Description

1 piece M48T08-150PC1
TIMEKEEPER® SRAM
64 Kbit (8 Kb x 8) | 150ns | Vcc 4.75 to 5.5 V | PCDIP28 package
Manufacturer: STMicroelectronics
Package: PCDIP28
Product Family: TIMEKEEPER® SRAM
Integrated ultra low power SRAM, real-time clock, power-fail control circuit, and battery
Pin and function compatible with DS1643 and JEDEC standard 8 K x 8 SRAMs
The M48T08/18/08Y TIMEKEEPER® RAM is an 8 K x 8 non-volatile static RAM and realtime clock which is pin and function compatible with the DS1643. The monolithic chip is available in two special packages to provide a highly integrated battery-backed memory and real-time clock solution.
The M48T08/18/08Y is a non-volatile pin and function equivalent to any JEDEC standard 8 K 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.
The 28-pin, 600 mil DIP CAPHAT™ houses the M48T08/18/08Y silicon with a quartz crystal and a long-life lithium button cell in a single package.
Integrated ultra low power SRAM, real-time clock, power-fail control circuit, and battery
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
Automatic power-fail chip deselect and WRITE protection
WRITE protect VPFD = power-fail deselect voltage):
– M48T08: VCC = 4.75 to 5.5 V; 4.5 V ≤ VPFD ≤ 4.75 V
– M48T18/T08Y: VCC = 4.5 to 5.5 V; 4.2 V ≤ VPFD ≤ 4.5 V
Software controlled clock calibration for high accuracy applications
Self-contained battery and crystal in the CAPHAT™ DIP package
Packaging includes a 28-lead SOIC and SNAPHAT® top (to be ordered separately)
SOIC package provides direct connection for a snaphat top which contains the battery and crystal
