23A256-I/P Memory by Microchip Technology

1.5-1.95V 256Kb SPI Serial SRAM


The Microchip Technology Inc. 23X256 are 256 Kbit Serial SRAM devices. The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input. Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of Chip Select, allowing the host to service higher priority interrupts. The 23X256 is available in standard packages including 8-lead PDIP and SOIC, and advanced packaging including 8-lead TSSOP.
