Ramtron International Corp. has launched the FM3135, a 64kbit, 3V processor companion product that combines the benefits of non-volatile FRAM memory with an enhanced real-time clock/calendar (RTC) and integrated 32kHz watch crystal.

The FM3135 is designed for use in meters, elapsed time monitors, time-of-use recording and other data-storage applications that require time-stamping. The high endurance and fast writes of FRAM combined with an RTC make it suitable for systems that time stamp events.

The FM3135 combines 64Kbit of FRAM with an RTC that incorporates an alarm and a programmable frequency clock output. The alarm compares user-programmed alarm values to corresponding RTC time/date values, creating a solution optimized for applications such as high-end TV sets that boast automatic on/off, channel switch and parental controls, and personal video recorder functions. An industry-standard 2-wire bus is used to access the memory and to control the RTC. Available in a 20-pin SOIC package, the FM3135 operates at 2.7-3.6V over the industrial temperature range (-40C to 85C).

Pricing starts at $3.20 in 10,000 quantities.

Samples are available in a 20-pin SOIC.
