Ramtron International Corp. introduced its FRAM-based Processor Companion family featuring highly integrated support and peripheral functions for processor-based systems. The FM3104, FM3116, FM3164 and FM31256 devices combine a nonvolatile ferroelectric random access memory (FRAM) with a real-time clock (RTC), a processor supervisor and additional peripheral functions. The Processor Companion family provides commonly needed system functions for a variety of automotive, consumer, communications, industrial, metering and computing applications, added the company.

The FM31X Processor Companion family includes a processor supervisor that features a programmable low-VDD reset, a programmable watchdog timer and a manual reset function. Additional peripherals include a nonvolatile event counter, a lockable 64-bit serial number area and a general-purpose comparator that can be used for an early power-fail (NMI) interrupt or other purpose. Implementing these complementary but distinct functions using an advanced 0.35?m manufacturing process allows them to share a common interface and combine to fit in a tiny 14-pin SOIC package, replacing the need for multiple parts on a system board, explained Ramtron. An industry-standard 2-wire bus is used to access the memory and control all functions. All devices operate from 2.7V to 5.5 and are available in 4Kb, 16Kb, 64Kb and 256Kb densities.

"No other processor support chip has the unique nonvolatile memory features of unlimited endurance and fast read/write," shared Mike Alwais, VP of FRAM products at Ramtron. "The Processor Companion family also gives system designers the most highly integrated system management solution to support virtually any microcontroller- or microprocessor-based design. Through the careful integration of nonvolatile memory, all individual features are improved versus discrete versions and the total package achieves superior bill-of-material cost and board space."

Samples are available for the FM3104, FM3116, FM3164 and FM31256 in a 14-pin SOIC package, with prices starting at $1.81 for 4Kb, $2.02 for 16Kb, $2.36 for 64Kb, and $3.25 for 256Kb, all in for 25,000-piece quantities.
