Ramtron International Corp. has beefed up its FM31x processor companion family to include a more efficient trickle charger and a real-time clock (RTC) that requires a standard 12.5pF external watch crystal.

The FM3127x/L27x processor companion features 4, 16, 64, or 256Kbits of non-volatile FRAM memory, a high-speed two-wire interface, and highly integrated support and peripheral functions for advanced processor-based systems.

It replaces discrete components and reduces cost and board space in processor-based designs. It supports commonly needed system functions in a variety of metering, consumer, communications, industrial, and computing applications.

The FRAM memory on the processor companion offers NoDelay writes, virtually unlimited endurance, and low power consumption. The FM32127x/L27x features an enhanced trickle charger, a 12.5pF external watch crystal, 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 (NMI).

The FM31272, FM31274, FM31276, and FM31278 operate from 4.0-5.5V over the entire industrial temperature range (-40 to +85 °C). The FM31L272, FM31L274, FM31L276, and FM31L278 operate from 2.7-3.6V over the entire industrial temperature range.

Unit pricing begins at Rs.71.46 ($1.81) in high volume. Samples of the FM3127x and FM31L27x are now available in a RoHS-compliant, 14-pin SOIC package.
