Description

1 piece M48T12-70PC1
TIMEKEEPER® SRAM
16 Kbit (2 Kb x 8) | 70ns | Vcc 4.5 to 5.5 V | PCDIP24 package
Manufacturer: STMicroelectronics
Package: PCDIP24
Product Family: TIMEKEEPER® SRAM
Integrated, ultra low power SRAM, real-time clock, and power-fail control circuit
Pin and function compatible with JEDEC standard 2 K x 8 SRAMs
The M48T02/12 TIMEKEEPER® RAM is a 2 Kb x 8 non-volatile static RAM and real-time clock which is pin and functional compatible with the DS1642.
A special 24-pin, 600 mil DIP CAPHAT™ package houses the M48T02/12 silicon with a quartz crystal and a long life lithium button cell to form a highly integrated battery-backed memory and real-time clock solution.
The M48T02/12 button cell has sufficient capacity and storage life to maintain data and clock functionality for an accumulated time period of at least 10 years in the absence of power over the operating temperature range.
The M48T02/12 is a non-volatile pin and function equivalent to any JEDEC standard 2 Kb x 8 SRAM. It also easily fits into many ROM, EPROM, and EEPROM sockets, providing the non-volatility of PROMs without any requirement for special WRITE timing or limitations on the number of WRITEs that can be performed.
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 compatible with JEDEC standard 2 K x 8 SRAMs
