The 8051-based VRS51L3072 microcontroller from Ramtron offers 2 kbytes of F-RAM
nonvolatile ferroelectric memory. F-RAM memory was added to the Versa 8051 family for
a quick and reliable nonvolatile data storage
and processing system that's ideal
for saving system status, data logging,
and storing nonvolatile variables for applications
ranging from sensors and meters
to industrial controls, instrumentation,
and medical devices.
F-RAM simplifies the design cycle by
eliminating the code overhead associated
with integrating flash memory. It also significantly
increases the number of write
cycles while reducing the cycle time. And
unlike flash, F-RAM bytes can be modified
without first erasing an entire sector.
The VRS51L3072 also features a 40-MIPS, single-cycle 8051-core; 64 kbytes of flash;
4 kbytes of SRAM; support for DSP extensions; and a robust digital peripheral set. It operates
at 3.3 V over the entire industrial temperature range. Engineering samples are available
now in 64-QFN packages. Pricing starts at $4.50 for quantities of 10,000 units.
