M48Z2M1Y 5V或3.3V的,16兆位( 2MB的× 8 ) ZEROPOWER ?SRAM
The M48Z2M1Y/V ZEROPOWER? RAM is a nonvolatile 16,777,216-bit, Static RAM organized as 2,097,152 words by 8 bits. The device combines two internal lithium batteries, CMOS SRAMs and a control circuit in a plastic 36-pin DIP, long Module.
The ZEROPOWER RAM replaces industry standard SRAMs. It provides the nonvolatility of PROMs without any requirement for special WRITE timing or limitations on the number of WRITEs that can be performed.
M48Z2M1Y 技术特性:
- INTEGRATED, ULTRA LOW POWER SRAM,
POWER-FAIL CONTROL CIRCUIT, AND
BATTERIES - CONVENTIONAL SRAM OPERATION;
UNLIMITED WRITE CYCLES - 10 YEARS OF DATA RETENTION IN THE
ABSENCE OF POWER - AUTOMATIC POWER-FAIL CHIP
DESELECT AND WRITE PROTECTION - WRITE PROTECT VOLTAGES
(VPFD = Power-fail Deselect Voltage):
– M48Z2M1Y: VCC = 4.5 to 5.5V
4.2V ≤ VPFD ≤ 4.5V
– M48Z2M1V: VCC = 3.0 to 3.6V
2.8V ≤ VPFD ≤ 3.0V - BATTERIES ARE INTERNALLY ISOLATED
UNTIL POWER IS APPLIED - PIN AND FUNCTION COMPATIBLE WITH
JEDEC STANDARD 2Mb x 8 SRAMs
