The Microchip Technology 23A256-I/ST is a 256 Kbit Serial SRAM device featuring low-power CMOS technology. It is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus, requiring SCK, SI, and SO lines, controlled by a Chip Select (CS) input.
Key electrical specifications include a maximum clock frequency of 20 MHz, an operating voltage range of 1.7V to 1.95V, and a read current of 3 mA at 1 MHz. The device also offers a low standby current of 4 µA maximum at +85°C.
This SRAM device has a memory organization of 32K x 8 bits with a 32-byte page size. It supports flexible operating modes including byte read/write, page mode, and sequential read/write operations. The HOLD pin allows communication to be paused without losing data.
The 23A256-I/ST is supplied in an 8-TSSOP package with surface mount mounting type. It operates within an industrial temperature range of -40°C to +85°C.
