SUMMARY DESCRIPTION
The M40SZ100Y/W NVRAM Controller is a selfcontained device which converts a standard lowpower SRAM into a non-volatile memory. A precision voltage reference and comparator monitors the VCC input for an out-of-tolerance condition.
FEATURES SUMMARY
■ CONVERT LOW POWER SRAMs INTO NVRAMs
■ 5V OR 3V OPERATING VOLTAGE
■ PRECISION POWER MONITORING and POWER SWITCHING CIRCUITRY
■ AUTOMATIC WRITE-PROTECTION WHEN VCC IS OUT-OF-TOLERANCE
■ CHOICE OF SUPPLY VOLTAGES and POWER-FAIL DESELECT VOLTAGES:
– M40SZ100Y: VCC = 4.5 to 5.5V; 4.20V ≤ VPFD ≤ 4.50V
– M40SZ100W: VCC = 2.7 to 3.6V; 2.55V ≤ VPFD ≤ 2.70V
■ RESET OUTPUT (RST) FOR POWER ON RESET
■ 1.25V REFERENCE (for PFI/PFO)
■ LESS THAN 10ns CHIP ENABLE ACCESS PROPAGATION DELAY (at 5V)
■ OPTIONAL PACKAGING INCLUDES A 28- LEAD SOIC and SNAPHAT? TOP (to be ordered separately)
■ 28-LEAD SOIC PACKAGE PROVIDES DIRECT CONNECTION FOR A SNAPHAT TOP WHICH CONTAINS THE BATTERY
■ BATTERY LOW PIN (BL)
