8051-based microcontroller with non-volatile FRAM memory
Ramtron International has launched the VRS51L3074, said to be the market’s first 8051-based microcontroller with non-volatile FRAM memory. Ramtron has added FRAM into its Versa 8051s for quick and reliable non-volatile data storage and a processing system that only a FRAM-enhanced MCU can provide.“T
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.
The VRS51L3074 combines 8KB of FRAM memory with a fully-integrated, high-performance system-on-chip. Features include an advanced 40-MIPS, single-cycle 8051-core, 64KB Flash with In-System/In-Application Programming, 4KB SRAM, a JTAG program/debug interface, digital signal processing (DSP) extensions and a robust digital peripheral set. Operating at 3.3 volts over the entire industrial temperature range, the VRS51L3074 offers the ideal embedded data acquisition solution, targeting a wide array of applications from sensors and metering to industrial control, instrumentation and medical devices.
