M48T37Y-70MH1E - Brand New STMicroelectronics Real-time Clocks (RTC)
-
Description
The M48T37Y/V TIMEKEEPER® RAM is a 32 Kb x 8 non-volatile static RAM and real- time clock. The monolithic chip is available in a special package which provides a highly integrated battery-backed memory and real-time clock solution. The 44-lead, 330 mil SOIC package provides sockets with gold-plated contacts at both ends for direct connection to a separate SNAPHAT housing containing the battery and crystal. The unique design allows the SNAPHAT® battery/crystal package to be mounted on top of the SOIC package after the completion of the surface mount process.
Features
■ Integrated ultra low power SRAM, real-time clock, power-fail control circuit, and battery
■ Frequency test output for real-time clock software calibration
■ Automatic power-fail chip deselect and WRITE protection
■ Watchdog timer
■ WRITE protect voltage(VPFD= Power-fail deselect voltage):
–M48T37Y: VCC= 4.5 to 5.5 V
4.2 V ≤VPFD ≤4.5 V
–M48T37V: VCC= 3.0 to 3.6 V
2.7 V ≤VPFD ≤3.0 V
■ Packaging includes a 44-lead SOIC and SNAPHAT®top (to be ordered separately)
■ SOIC package provides direct connection for a SNAPHAT®top which contains the
battery and crystal
■ Microprocessor power-on reset (valid even during battery backup mode)
■ Programmable alarm output active in the battery backup mode
■ Battery low flag
■ RoHS compliant
