Description

1 piece MK48T12B15
TIMEKEEPER SRAM
16 Kbit (2Kb x 8) | 200ns | Vcc 4.5 to 5.5V | PHDIP24
MK48T12B20 = M48T12 = DS1642
Manufacturer: STMicroelectronics
Package: PHDIP24 with Battery Top Hat (B)
Product Family: TIMEKEEPER
MK48T02/12 versus M48T02/12 are the same devices (pinning ,parameters, etc.), only the construction of the package is slightly different (but the pitch/layout is equal)
PIN and FUNCTION COMPATIBLE WITH JEDEC STANDARD 2K x 8 SRAMs like 6116 , 5517 and to DS1642 ,M48T12 , M48T02
The MK48T02/12 TIMEKEEPERTM RAM combines a 2K x 8 full CMOS SRAM, a BYTEWIDETM accessible real time clock, a crystal and a long life lithium carbon mono-fluoride battery, all in a single plastic DIP package The MK48T02/12 is a non-volatile pin and function equivalent to any JEDEC standard 2K x 8 SRAM, such as the 6116 or 5517. lt also easily fits into many EPROM AND EEPROM sockets, providing the non-volatility of the PROMs without any requirement for special write timing, or Iimitations on the number of writes that can be performed
