• Manufacturer Part Number: m48t201v
• Description: 5.0 Or 3.3v Timekeeper Supervisor
• Manufacturer: STMicroelectronics

Note:
Most low power SRAMs on the market today can be used with the M48T201Y/V
TIMEKEEPER
making the final choice of an SRAM to use.
The SRAM must be designed in a way where the chip enable input disables all other inputs
to the SRAM. This allows inputs to the M48T201Y/V and SRAMs to be “Don't care” once
V
2.0V. The chip enable access time must be sufficient to meet the system needs with the chip
enable (and output enable) output propagation delays included.

SUPERVISOR. There are, however some criteria which should be used in
PFD
(min). The SRAM should also guarantee data retention down to V
