PRESTO - Fast ICSP Programmer - PICS & more PRESTO - fast and flexible USB programmer PRESTO is a powerful, very fast and cost effective programmer for wide range of popular components - microcontrollers, serial EEPROM and Flash memory chip, CPLDs and others. PRESTO operates on the USB port and requires no external power supply. High speed PRESTO is optimized for speed and it is really very fast, for example the full PIC18F8720 is programmed and verified in 6 seconds! (3 seconds for programming and 3 seconds for verification). Complete eCOG1 in less than 3 seconds. Many devices supported Hundreds of devices are supported by the UP software and the list is growing continuously. Moreover, many other parts can be programmed using JTAG. For more information, see the paragraph "Wide range of supported devices" below. Enhanced programming interface In-Circuit Serial Programming (ICSP) is a very useful and often used PIC feature. PRESTO directly supports this function using a dedicated connector and an included cable. In comparison to other ASIX' programmers, the ICSP connector is enhanced - there are two more pins allowing support of wider range of components such as Atmel's MCUs, devices with JTAG interface and many serially programmable memory chips. The target application device can be either powered by PRESTO (5 V nominally) or can be powered by an application within a voltage range from 3 to 5 V (with 10% tolerance, i.e. 2.7 to 5.5 V). Overcurrent limitation of target supply and programming voltages remarkably reduces the risk of damaging the parts because of user mistakes. Target supply overvoltage detection is also implemented. Advanced software The program UP supports PRESTO as well as other ASIX' programmers. It offer many advanced functions like projects, command line control, Windows message control, workspace setup including user keyboard shortcut definitions, serial number generation by various methods etc. Devices with JTAG interface and eCOG microcontrollers are supported by dedicated programs eCOG Programmer and JTAG SVF Player. The software upgrade is freely available for all users on the Internet. It contains new device support, new functions and algorithm updates when required. Comfortable user interface GO button allows user to start device programming comfortably, without need of PC keyboard or mouse. LEDs indicate programmer status - green LED ON-LINE informs about USB connection and yellow LED ACTIVE indicates that PRESTO is just working (programming, reading, ...). PRESTO is powered from the USB bus, so there is no need for any additional supply adaptor. PRESTO is small, lightweight and compact.

MU Beta Real-Time Hardware PIC Emulator The unique and affordable PIC emulator (Parallel Port) MU Beta is a Real-Time In-Circuit Emulator for the most popular 6-pin to 18-pin Microchip PIC® microcontrollers. It offers many professional level features for a very low price. It is designed to multiply your productivity and comfort in the development of PIC applications. It is extremely beneficial as an educational tool. Small system design - when designing systems based on small PIC MCUs like power supplies, sensors, alarms, simple communication units, robots, controllers, toys, etc., the MU Beta will cut the time required for firmware development to only a fraction. You can focus on new features of your product rather than spending hours by looking for forgotten data bank select bit... Complex systems with distributed intelligence - when using more processors, why not to use more emulators? The price of MU Beta allows for such solution. Then, the debugging of tasks like inter-processor communication will no longer be a nightmare. Educational - excellent tool for the most efficient teaching of embedded microcontroller technology. Enables your students to fast and deeply understand the processes inside the microcontrollers - why to waste time by describing a behavior of a "black box" when you can demonstrate everything absolutely clearly. Many advanced technical features Extremely flexibile MU Beta is based on the state-of-the-art programmable gate arrays (FPGA). This solution is far more flexible and offers more functionality than the "traditional" one, based on bond-out chips specially manufactured. The analogue peripherals are designed to be compatible with the ones found on the original PIC MCUs. The target device type, clock frequency, oscillator type, reset, watchdog and many other parameters are software selectable, with no confusing jumper settings or interchangeable oscillator modules. The user only needs to connect one of the small target probes for 6-pin to 18-pin devices. An internal clock frequency synthesizer provides the clock in the range from 25 kHz to 20 MHz (full speed of emulated devices). The user can select among various oscillator modes: crystal, RC with CLKOUT equal to Fosc/4, external clock up to 10 MHz, or external RC oscillator. Target application independent functionality: the emulator can be used with or without a target system (which allows to test internal routines independently of application), like a "real-time software simulator". Really non-intrusive All device resources are available for the user's application. Nothing is used by the emulator hardware or software. MU Beta offers excellent device resource accessibility even when running at full application speed, so you do not have to stop the real-time run to watch and modify the device registers. Low voltage support Low voltage applications? No problem with MU Beta. Target application supply voltage can be as low as 2 V and your emulator will still work fine. No obvious 5 V only limitations. Extensive break logic options Extensive break logic possibilities: Unlimited number of breakpoints anywhere in the code memory, activated BEFORE instruction execution. Many other break conditions: file register breaks in data memory, Timer0 overflow, Trace buffer overflow, Watchdog timer overflow, Stack overflow/underflow, Break on external input (Trigger In). Many other beneficial features... 32-bit instruction cycle counter - stopwatch - with overflow detection accurately counts active cycles both in Run or Step modes. The time is displayed in cycles and in microseconds. A second - differential - counter is implemented in software. Flexibility of emulator circuitry allows software upgrades (e.g. via Internet) of the emulator hardware. Trace memory 256 instructions deep, tracing is fully user selectable for arbitrary (even discontinuous) locations and areas.   Datasheet Price:  £249.99 (Ex VAT) £293.74 Including VAT at 17.5%

ISP2ZIF - Programming Adapter with ZIF Socket ISP2ZIF is an adapter for programming of all types of devices with In-Circuit Serial/In-System Programming (ICSP/ISP), especially with the PRESTO programmer. The adapter is provided with the 40-pin Zero Insertion Force socket (ZIF) which accepts 300 to 600 mils wide devices. ISP2ZIF works well for most of programmable devices like Microchip PIC® and Atmel AVR and AT89S ('51 architecture) microcontrollers in DIP packages up to 40 pins. The user can connect any device pin to any of 7 programming signals (VPP/13V, VDD, GND, DATA/MOSI, CLOCK, MISO, LVP). Typical usage example: The user connects the ISP2ZIF to the PRESTO using a ICSP cable supplied with the programmer. Device to be programmed (e.g. PIC or AVR MCU) then smoothly fits into the ZIF socket. The user then connects programming signals to corresponding pins of the device by plugging jumpers to appropriate positions in the pin array. It is also possible to use the ISP2ZIF as a prototyping board.   Datasheet Price:  £29.99 (Ex VAT) £35.24 Including VAT at 17.5%
	SPINET - Ethernet to SPI interface module SPINET is a module based on ENC28J60 Ethernet controller by Microchip. It provides easy connection of any microcontroller like Microchip PIC or Atmel AVR to an Ethernet network. SPINET contains 10BASE-T physical layer (PHY) including RJ45 connector with galvanic insulation and media access control logic (MAC). The heart of SPINET - the ENC28J60 chip - is an IEEE 802.3 compliant stand-alone Ethernet controller. It supports half duplex and full duplex operation at 10 Mb/s and it is equipped by 8 KB of dual port SRAM for incoming and outgoing data. Besides of other features it includes hardware engine for copying blocks of memory and checksum calculation in one's complement arithmetics (IP checksum) and CRC. It connects to an external microcontroller by SPI interface which can be easily implemented in any microcontroller and requires only 4 or 5 signals. The module is powered by single power supply - either +3.3 V or +5 V. All module inputs are LVTTL and are 5 V tolerant. All outputs are doubled - they are available in 3.3 V levels (connected directly to ENC28J60) and, if 5 V power supply is used, also in 5 V levels. This is necessary for AVR microcontrollers operated on 5 V which have CMOS input levels and cannot reliably work with 3.3 V signals. Two LED indicators on the RJ45 connector help user to monitor the Ethernet activity. Four mounting holes allow for firm mechanical fixation of the SPINET module in user's equipment. SPI interface is connected to the open holes which allow for flexible connection of the cable or 2.54 mm/0.1 inch header (top/bottom, straight/right angle). An example program in C is available royalty free. It is written for the PVK40 development board with PIC18F458 but this can be easily modified for other microcontrollers.
