F-RAM devices upgraded

6 February 2008 DSP, Micros & Memory

Ramtron has upgraded its FM31x Processor Companion family to include a more efficient trickle charger and a realtime clock (RTC) that requires only a standard 12,5 pF external watch crystal. The new FM3127x/L27x Processor Companion features 4, 16, 64, or 256 Kbits of nonvolatile F-RAM memory, a high-speed two-wire interface, and integrated support and peripheral functions for advanced processor-based systems.

The F-RAM memory on these new Processor Companions boasts NoDelay writes, virtually unlimited endurance, and low power consumption. The FM32127x/L27x features a programmable low-VDD reset, a programmable watchdog timer, a manual reset function, dual battery-backed event counters, a lockable serial number, and a general-purpose comparator that can be used for early warning power-fail interrupts.
