FRAM-enhanced processor companion family with high-speed serial interface
(Technology News, 05 Jun 2007 )
Ramtron International Corporation has introduced the FM33x product family – a new line of FRAM-Enhanced Processor Companions with a high-speed serial peripheral interface (SPI). The FM33x family combines, in one small package, all the benefits of a nonvolatile RAM with a comprehensive set of highly-integrated support and peripheral functions for processor-based designs.
Ramtron launches the 33x Processor Companion family with two products: the FM33256 and the FM3316, which are 3-volt devices with 256 kilobits and 16 kilobits of FRAM, respectively. This single-chip solution replaces discrete components and reduces cost and board space, supporting commonly-needed system functions in processor-based systems such as meters and automotive telematics applications.
The FM33x family incorporates a nonvolatile FRAM memory with No Delay™ writes, virtually unlimited endurance and low power consumption. The devices also include a real-time clock/calendar/alarm (RTC), as well as processor companion features such as a programmable low-VDD reset, a programmable watchdog timer, a manual reset function, a nonvolatile event counter, a lockable serial number, and a general-purpose comparator that can be used for early warning power-fail interrupts (NMI). The devices operate from 2.7 to 3.6 volts over the entire industrial temperature range (-40 degrees C to +85 degrees C).
