Ramtron Reduces Costs with Highly Integrated FRAM-based Processor

10/29/2003 - Ramtron International Corporation (Nasdaq:RMTR), the leading supplier of nonvolatile ferroelectric memory products, 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. Ramtron’s Processor Companion family, which is the most integrated FRAM product developed to date, provides commonly needed system functions for a variety of automotive, consumer, communications, industrial, metering, and computing applications.

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-micron 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. An industry standard 2-wire bus is used to access the memory and control all functions. All devices operate from 2.7 to 5.5V 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,” stated Mike Alwais, VP FRAM products of Ramtron International Corporation. “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 discreet versions and the total package achieves superior bill of material cost and board space,” he said.

Features of the Processor Companion:

Pricing and Availability
Samples are available for the FM3104, FM3116, FM3164 and FM31256 in a 14-pin SOIC package with prices starting at $2.04 for 4Kb, $2.34 for 16Kb, $2.75 for 64Kb and $3.76 for 256Kb for 10,000 piece quantities.

About the 0.35 Micron and IT/IC FRAM Technology
Advances in ferroelectric memory design and manufacturing have enabled commercial FRAM products using 0.35-micron geometries and a more efficient 1T/1C memory architecture. The Processor Companion family represents the first commercial advanced nonvolatile memory product featuring 1T/1C memory cells on one of the most widely used semiconductor process nodes.
