S-22H10R/I

The S-22H10R/I is a non-volatile CMOS RAM,composed of a CMOS static RAM and a non-volatile electrically erasable programmable memory (E2PROM) to backup the SRAM.The organization is 64-word * 4-bit(total 256 bits) and the RAM is asynchronously CMOS static.The pin layout is compatible with X2210 of Ltd.When a store signal is input to the SRAM,all the data is copied into the E2PROM.When a recall signal is input,the E2PROM data is recopied into the SRAM.

The S-22H10R/I has some absolute maximum ratings.When item is storage temperature,the symbol is Tstg,the condition is S-22H10R,the rating is -65 to +125,the unit is .When item is storage temperature,the symbol is Tstg,the condition is S-22H10I,the rating is -65 to +150,the unit is .When item is storage temperature under bias,the symbol is Tbias,the condition is S-22H10R,the rating is -10 to +85,the unit is .When item is storage temperature under bias,the symbol is Tbias,the condition is S-22H10I,the rating is -50 to +95,the unit is .When item is power supply voltage,the symbol is VCC,the rating is -0.3 to +6.0,the unit is V.When item is input voltage,the symbol is VIN,the rating is -0.3 to VCC+0.3,the unit is V.When item is output voltage,the symbol is Vout,the rating is 0.0 to VCC,the unit is V.
