A universal serial bus (USB) interface for in-circuit programming / debugging is now included with Ramtron's 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 the company'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 USB interface capability and can be used independent of the VersaKit devboard to program Ramtron MCUs installed on other target hardware. The VersaKit-30xx includes:
Development board with VRS51L3074 device, VJTAG-USB in-circuit programming / debugging interface and USB cable 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, says the company.
