Processor companion embeds 64-Kbit FRAM, 32-KHz crystal

Colorado Springs, Colo.—Ramtron International Corp. has launched the FM3135, a 64-kbit, 3-V processor companion product that combines the benefits of non-volatile FRAM memory with an enhanced real-time clock/calendar (RTC) and integrated 32 kHz 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 ideal for systems that time stamp events.

The FM3135 combines 64-Kbit 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 an ideal solution for applications such as high-end televisions that boast automatic on/off, channel switch and parental controls, and personal video recorder (PVR) 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 to 3.6 volts over the entire industrial temperature range (-40°C to +85°C).

Pricing: Starting at $3.20 in 10K quantities.
Availability: Samples are available in a 20-pin SOIC.
