FPGA and CPLD devices by Xilinx, Altera and Lattice, ...
- Very fast operation
- Controlled and powered by USB
- Target application voltage 3 to 5 V
- Overcurrent and overvoltage protection
- GO button
- RoHS compliant
- New enclosure since April 2010
- Advanced software for Windows XP/Vista/7/8/8.1/10 (both 32 & 64 bit) and Linux (using Wine)

More information about PRESTO
PRESTO is optimized for high speed, for example it programs and verifies a full PIC18F8720 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 or other
software for PRESTO. For detailed information, visit the page
Enhanced programming interface
In-Circuit Serial Programming (ICSP) or In-System Programming (ISP) is a very beneficial and frequently used MCU feature. PRESTO directly supports this function using a dedicated connector and an included cable.
The target application device can be either powered by PRESTO (5 V nominally) or powered by an application within a voltage range of 3 to 5 V (with a ±10% tolerance, i.e. 2.7 to 5.5 V). The voltage range can be extended by two special headers -
HPR3V3 (for 3.3 V output) and
HPR1V2 (for 1.2 to 3.3 V support).
Overcurrent limitation on target supply and programming voltages remarkably reduces the risk of damaging parts because of operator error. Target supply overvoltage detection is also implemented.
UP supports PRESTO as well as other ASIX' programmers. It offers 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. UP works in Windows XP/Vista/7/8/8.1/10 (32 and 64 bit) as well as in
Linux (using Wine).
Devices with JTAG interface and eCOG microcontrollers are supported by dedicated programs
JTAG SVF Player and eCOG Programmer, respectively. Microcontrollers with 32-bit ARM core are supported by OpenOCD and some of them also by easy-to-use Armine application. The advanced control of the PRESTO programmer can be made using a
PRESTO .DLL Library.
Software upgrades are freely available for all users on the Internet. They contain new device support, new functions and algorithm updates if required.
LINUX support (using WINE).
Comfortable user interface
GO button allows the user to comfortably start the device programming, without the need for a PC keyboard or a mouse. LEDs indicate programmer status - green LED ON-LINE signals a working USB connection and yellow LED ACTIVE indicates that PRESTO is operating (programming, reading, ...).
PRESTO is powered by the USB bus, so there is no need for any additional supply adaptor.
PRESTO is small, lightweight and compact.
Since spring 2012 there is a new enclosure and label colour
To achieve a consistent colour scheme for our new products, we changed the PRESTO enclosure colour from light gray to light beige, the colour of the plastic reduction at the ICSP connector from dark grey to orange and the product name from red to orange. Of course, dimensions and weight (as well as the electronics) remained unchanged.
PRESTO is delivered in a new enclosure since April 2010
