M48T08, M48T08Y, M48T18
Operation modes
When VCC drops below VSO, the control circuit switches power to the internal battery which
preserves data and powers the clock. The internal button cell will maintain data in the
M48T08/18/08Y for an accumulated period of at least 10 years when VCC is less than VSO.
Note:
Requires use of M4T32-BR12SH SNAPHAT top when using the SOH28 package.
As system power returns and VCC rises above VSO, the battery is disconnected and the
power supply is switched to external VCC.
Write protection continues until VCC reaches VPFD (min) plus trec (min). E1 should be kept
high or E2 low as VCC rises past VPFD (min) to prevent inadvertent WRITE cycles prior to
system stabilization. Normal RAM operation can resume trec after VCC exceeds VPFD (max).
For more information on battery storage life refer to the application note AN1012.
2.4
Power-fail interrupt pin
The M48T08/18/08Y continuously monitors VCC. When VCC falls to the power-fail detect trip
point, an interrupt is immediately generated. An internal clock provides a delay of between
10 s and 40 s before automatically deselecting the M48T08/18/08Y. The INT pin is an
open drain output and requires an external pull-up resistor, even if the interrupt output
function is not being used.
