ASIX - Presto: Fast and Flexible USB Programmer

• Wide range of supported devices: Microcontrollers by Microchip/Atmel, Texas Instruments and Cypress/Infineon, serial EEPROM & Flash memories by various manufacturers, FPGA and CPLD devices by AMD/Xilinx, Intel/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/7/8/8.1/10/11 (both 32 & 64 bit)

High speed: 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. Moreover, many other parts can be programmed using JTAG or other software for PRESTO. For detailed information, visit the page Supported Devices.

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.

Advanced software: The program 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/7/8/8.1/10/11 (32 and 64 bit).

Devices with JTAG interface are supported by dedicated program JTAG SVF Player (provided that the corresponding development software can create a standard SVF file for them). 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.

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.
