Description
M48T08-150PC1 Integrated Circuits
The M48T08/18/08Y TIMEKEEPER® RAM is an 8 K x 8 non-volatile static RAM and real-time clock that is pin and function compatible with the DS1643.
This monolithic chip is offered in two specialized packages, delivering a highly integrated solution for battery-backed memory and real-time clock functionality.
The M48T08/18/08Y serves as a non-volatile equivalent in pin and function to any JEDEC standard 8 K x 8 SRAM.
It seamlessly fits into various ROM, EPROM, and EEPROM sockets, offering the non-volatility of PROMs without necessitating special WRITE timing or imposing limitations on the number of WRITEs that can be executed.
The 28-pin, 600 mil DIP CAPHAT™ encapsulates the M48T08/18/08Y silicon along with a quartz crystal and a long-lasting lithium button cell within a single package.
The 28-pin, 330 mil SOIC features sockets with gold-plated contacts at both ends, allowing for direct connection to a separate SNAPHAT® housing that contains the battery and crystal.
This innovative design permits the SNAPHAT® battery package to be mounted atop the SOIC package following the completion of the surface mount process.
Inserting the SNAPHAT® housing after reflow mitigates the risk of potential damage to the battery and crystal due to the elevated temperatures required for surface-mounting the device.
The SNAPHAT® housing is designed with a key to prevent reverse insertion.
The SOIC and battery/crystal packages are supplied separately in plastic anti-static tubes or in tape & reel format.
For the 28-lead SOIC, the part number for the battery/crystal package (e.g., SNAPHAT®) is “M4T28-BR12SH” or “M4T32-BR12SH.”
