USB interface for MCU development kit

Ramtron International product story
Edited by the Manufacturingtalk editorial team
Feb 12, 2007
USB-based JTAG interface enables faster programming and superior in-circuit debugging.
Ramtron International will offer a universal serial bus (USB) interface for in-circuit programming/debugging with its Versa 8051 microcontroller development tools.
The VJTAG-USB, a USB-based JTAG interface, will ship with the VersaKit-30xx, a complete and comprehensive evaluation platform that facilitates system prototyping and design development with Ramtron's fast and flexible MCUs - the VRS51L2070 and the FRAM-Enhanced VRS51L3074.
The new USB board will enable faster device programming and superior in-circuit debugging.
It functions on Windows-based computers with a USB interface capability and can be used independently of the VersaKit devboard to program Ramtron MCUs installed on other target hardware.
The VersaKit-30xx includes a development board with VRS51L3074 device; VJTAG-USB in-circuit programming/debugging interface; a USB cable; and a power supply.
The development board incorporates a comprehensive set of probe vias and header footprints for easy access to chip peripherals and I/Os; an RS-232 transceiver and two DB9 connectors for UART access; eight user LEDs; two tact switches for manual reset/interrupt triggering; ample prototyping space; and a JTAG access for in-circuit programming and real-time debugging of the VRS51L2070/3074.
For evaluation of Ramtron's FRAM memory devices, the board also features an FM31256 Processor Companion, an FM25CL64 (serial SPI FRAM) and an FM24CL64 (serial I2C FRAM).
Ramtron programming and debugging software is provided free with the VersaKit-30xx.
