M48T02
M48T02 is 16Kbit (2 Kb x 8) TIMEKEEPER SRAM manufactured by STMicroelectronics.
Features
- Integrated, ultra low power SRAM, real-time clock, and power-fail control circuit
- BYTEWIDE™ RAM-like clock access
- BCD coded year, month, day, date, hours, minutes, and seconds
- Typical clock accuracy of ±1 minute a month, at 25 °C
- Software controlled clock calibration for high accuracy applications
- Automatic power-fail chip deselect and WRITE protection
- WRITE protect voltages (VPFD = power-fail deselect voltage):
- M48T02: VCC = 4.75 to 5.5 V; 4.5 V ≤ VPFD ≤ 4.75 V
- M48T12: VCC = 4.5 to 5.5 V; 4.2 V ≤ VPFD ≤ 4.5 V
- Self-contained battery and crystal in the CAPHAT™ DIP package
- Pin and function patible with JEDEC standard 2 K x 8 SRAMs
- Ro HS pliant
- Lead-free second level interconnect
