Colorado Springs, Co. Ramtron International Corp.'s new FM3130 is billed as a 64-kbit 3-volt FRAM-Enhanced processor companion device that combines the benefits of nonvolatile ferroelectric RAM with an integrated real-time clock/calendar (RTC) in one tiny package.
The FM3130 has been streamlined to reduce system cost and board space in consumer and computing applications, supporting commonly-needed system functions in products such as printers and high-definition televisions (HDTVs), without the need for discrete components. "The FM3130 has been optimized for price-sensitive applications," explains Mike Alwais, vice president of Marketing at Ramtron.
The real-time clock/calendar incorporates an alarm and a programmable frequency clock output, and uses a common 12pF watch crystal. The alarm compares user-programmed alarm values to corresponding RTC time/date values, creating an ideal solution for automatic on/off, channel switch and parental control and personal video recorder (PVR) functions in high-end televisions.
An industry-standard 2-wire bus is used to access the memory and to control the RTC. Available in an 8-pin TDFN (thin dual flat no-lead) package that is footprint-compatible with TSSOP8s, or a standard 8-pin, 150-mil SOIC package, the device operates from 2.7 to 3.6 volts over the entire industrial temperature range (-40 degrees C to +85 degrees C). The 8Kx8 FRAM is true nonvolatile RAM (not battery-backed). FRAM memory technology replaces system SRAM or nonvolatile memory since it reads and writes at bus speed with NoDelay writes, 10 year data retention and unlimited read/write endurance.
Samples of the FM3130 are currently available in an 8-pin SOIC package, with pricing starting at $2.20 in 10K quantities.
