The Microchip Technology 23A640-I/SN is a 64 Kbit Serial SRAM device accessed via a Serial Peripheral Interface (SPI) compatible serial bus. It offers a maximum clock frequency of 20 MHz and operates with a low-power CMOS technology. The memory is organized as 8192 x 8 bits with a 32-byte page size.
This SRAM device supports flexible operating modes including byte read/write, page mode, and sequential mode. It features a HOLD pin to pause communication, allowing the host to service higher priority interrupts without losing data. The device is designed for industrial temperature ranges, operating from -40°C to +85°C.
The 23A640-I/SN is available in an 8-lead SOIC package, suitable for surface mounting. Its voltage range is between 1.7V and 1.95V, with a typical read current of 3 mA at 1 MHz and a standby current of 4 µA maximum at +85°C. This component is Pb-Free and RoHS Compliant, and Halogen Free.
