Ramtron VRS51L3072 Block Diagram

The VRS51L3072 is a Ramtron FRAM-Enhanced 8051-based microcontroller that reaches 40 MIPS and incorporates 2-kbyte of FRAM, 64-kbyte ISP/IAP of Flash, and 4352 bytes of SRAM. The device is suitable for nonvolatile data storage/processing systems and uses the same instruction set as standard 8051s.

Features include a 40 MHz internal oscillator, an enhanced hardware arithmetic unit that features 16-bit multiplication/division, 32-bit addition, and a 32-bit barrel shifter for DSP operations, a JTAG-USB interface for in-circuit programming/debugging/emulation, a highly configurable system clock, UARTs with a dedicated baud rate generator (20-bit equivalent resolution), enhanced SPI, I²C, PWCs and PWMs, general purpose timers/counters, a watchdog timer, 49 interrupts that share 16 interrupt vectors, and a port change and pin change interrupt. The VRS51L3072 operates at 3.3 volts over the entire industrial temperature range and features 5V-tolerant I/Os. It is available in a QFP-64 package.

The VersaKit-30xx development and evaluation system facilitates system prototyping and design development with the VRS51L3174. The kit ships with a VJTAG-USB in-circuit programming/debugging interface, programming/in-circuit debugging software, and demo programs. The VersaKit-30xx can also be used to evaluate Ramtron's FRAM memory devices.
