Ramtron International Corp. has launched the VRS51L3074, touted to be the market's first 8051-based MCU with nonvolatile ferroelectric RAM (FRAM). The company said it has added FRAM into its fast and flexible Versa 8051s for a quick and reliable nonvolatile data storage and processing system that only a FRAM-enhanced MCU can provide.

"The VRS51L3074 represents an advance that could fundamentally alter the microcontroller landscape by providing all the advantages of FRAM on an MCU," explained Irv Lustigman, general manager of Ramtron Canada. "This is the first in a series of planned products leading to a microcontroller based entirely on FRAM, where FRAM will be used for program, data and register memory, eliminating the need for Flash and SRAM altogether."

FRAM simplifies the design cycle by eliminating the code overhead accompanying Flash data storage, and the limited endurance and drawn out write cycles of Flash/EEPROM. Unlike Flash, FRAM bytes can be modified without first erasing an entire sector, rendering it easier to use. And unlike Flash/EEPROM, FRAM provides virtually unlimited read/write cycles and fast data writes.

According to Ramtron, the new MCU combines 8Kbytes of FRAM memory with a fully-integrated, high-performance SoC. Features include an advanced 40MIPS, single-cycle 8051-core, 64Kbytes Flash with in-system/in-application programming, 4KByte SRAM, a JTAG program/debug interface, DSP extensions, and a robust digital peripheral set.

Operating at 3.3V over the entire industrial temperature range, said Ramtron, the MCU offers the ideal embedded DAQ solution, targeting a wide array of applications from sensors and metering to industrial control, instrumentation and medical devices.

The VRS51L3074 is currently sampling and costs under $5 in volume.
