描述 Description

The M40SZ100Y/W NVRAM Controller is a self-contained device which converts a standard low-power SRAM into a non-volatile memory. A precision voltage reference and comparator monitors the VCC input for an out-of-tolerance condition.

特性 Features

■ 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-oftolerance

■ 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(a)

■ Battery low pin (BL)

■ RoHS compliant

– Lead-free second level interconnect
