Description
The M40Z300/W NVRAM supervisor 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.
Features
■ Converts low power SRAM into NVRAMs
■ Precision power monitoring and power
switching circuitry
■ Automatic WRITE-protection when VCC is outof-tolerance
■ Two-input decoder allows control for up to
8 SRAMs (with 2 devices active in parallel)
■ Choice of supply voltages and power-fail
deselect voltages:
– M40Z300:
VCC = 4.5 V to 5.5 V
THS = VSS: 4.5 V ≤ VPFD ≤ 4.75 V
THS = VOUT: 4.2 V ≤ VPFD ≤ 4.5 V
– M40Z300W:
VCC = 3.0 V to 3.6 V
THS = VSS: 2.8 V ≤ VPFD ≤ 3.0 V
VCC = 2.7 V to 3.3 V
THS = VOUT: 2.5 V ≤ VPFD ≤ 2.7 V
■ Reset output (RST) for power on reset
■ Battery low pin (BL)
■ Less than 12 ns chip enable access
propagation delay (for 5.0 V device)
■ Packaging includes a 28-lead SOIC and
SNAPHAT® top (to be ordered separately), or
A 16-lead SOIC
■ SOIC package provides direct connection for a
SNAPHAT top which contains the battery
■ RoHS compliant
– Lead-free second level interconnect
