Description
The M48T86 is an industry standard real-time clock (RTC). The M48T86 is composed of a
lithium energy source, quartz crystal, write protection circuitry, and a 128-byte RAM array.
This provides the user with a complete subsystem packaged in either a 24-pin DIP
CAPHAT or 28-pin SNAPHAT SOIC. Functions available to the user include a non-
volatile time-of-day clock, alarm interrupts, a one-hundred-year clock with programmable
interrupts, square wave output, and 128 bytes of non-volatile static RAM.
The 24-pin, 600 mil DIP CAPHAT houses the M48T86 silicon with a quartz crystal and a
long-life lithium button cell in a single package.
The 28-pin, 330 mil SOIC provides sockets with gold plated contacts at both ends for direct
connection to a separate SNAPHAT housing containing the battery and crystal. The
unique design allows the SNAPHAT battery package to be mounted on top of the SOIC
package after the completion of the surface mount process.
Insertion of the SNAPHAT housing after reflow prevents potential battery and crystal
damage due to the high temperatures required for device surface-mounting. The SNAPHAT
housing is keyed to prevent reverse insertion.
The SOIC and battery packages are shipped separately in plastic anti-static tubes or in tape
& reel form.
For the 28-lead SOIC, the battery/crystal package part number is “M4T28-BR12SH” (see
