The Microchip Technology 23A256T-I/ST is a 256 Kbit Serial SRAM device designed for applications requiring efficient serial data storage. It utilizes a Serial Peripheral Interface (SPI) compatible serial bus, requiring SCK, SI, and SO lines for communication, controlled by a Chip Select (CS) input.
This SRAM device offers a memory organization of 32K x 8 bits and supports a maximum clock frequency of 20 MHz. It operates within a supply voltage range of 1.7V to 1.95V and is rated for an industrial temperature range of -40°C to +85°C.
The 23A256T-I/ST is available in an 8-TSSOP package, suitable for surface mounting. Its low-power CMOS technology ensures efficient operation with a typical read current of 3 mA at 1 MHz and a maximum standby current of 4 µA at +85°C. The device also features a HOLD pin to pause communication, allowing the host to service higher priority interrupts.
This component is Pb-Free and Halogen Free, aligning with environmental compliance standards. It is designed for high reliability and flexible operating modes including byte read/write, page mode, and sequential read/write operations.
