N01S818HA Datasheet (ON Semiconductor) - 1 Mb Ultra-Low Power Serial SRAM

N01S818HA, 1 Mb Ultra-Low Power Serial SRAM

Signal Mode Used Name Description CS All Chip Select A low level selects the device and a high level puts the device in standby mode.

If CS is brought high during a program cycle, the cycle will complete and then the device will enter standby mode.

When CS is high, SO is in high-Z.

CS must be

N01S818HA 1 Mb Ultra-Low Power Serial SRAM Standard SPI Interface and Multiplex DUAL and QUAD Interface Overview The ON Semiconductor serial SRAM family includes several integrated memory devices including this 1 Mb serially accessed Static Random Access Memory, internally organized as 128 K words by 8 bits.
