Ranges Packages 23K640 2.7-3.6V 32 Byte I P, SN, ST 23A640 1.7-1.95V 32 Byte I P, SN, ST Features: Description: Max. Clock 20 MHz The Microchip Technology Inc. 23X640 are 64 Kbit Serial SRAM devices. The memory is accessed via a Low-Power CMOS Technology: simple Serial Peripheral Interface (SPI) compatible - Read Current: 3 mA at 1 MHz serial bus. The bus signals required are a clock input - Standby Current: 4 A Max. at 3.6V (SCK) plus separate data in (SI) and data out (SO) 8192 x 8-bit Organization lines. Access to the device is controlled through a Chip 32-Byte Page Select (CS) input. HOLD pin Communication to the device can be paused via the Flexible Operating modes: hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the - Byte read and write exception of Chip Select, allowing the host to service - Page mode (32 Byte Page) higher priority interrupts. - Sequential mode The 23X640 is available in standard packages Sequential Read/Write including 8-lead PDIP and SOIC, and advanced High Reliability packaging including 8-lead TSSOP.
