Ramtron introduces 64-kilobit F-RAM enhanced processor companion with embedded 32 kHz crystal
Ramtron International Corporation has launched the FM3135, a 64-kilobit (Kb), 3-volt Processor Companion product that combines the benefits of nonvolatile F-RAM memory with an enhanced real-time clock/calendar (RTC) and integrated 32 kHz watch crystal.
New single-chip solution reduces bill of materials and eliminates fatigue on crystal pins; ideal for meters and other time-stamp applications
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 F-RAM combined with an RTC make it ideal for systems that time stamp events.
The FM3135 combines 64Kb of F-RAM 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.
