The Microchip Technology 23K640-I/ST is a 64 Kbit Serial SRAM with a 8K x 8 organization, utilizing a Serial Peripheral Interface (SPI) for communication. This device supports a maximum clock frequency of 20 MHz and operates within a voltage range of 2.7V to 3.6V.
Designed with low-power CMOS technology, it offers efficient operation with a read current of 3 mA at 1 MHz and a standby current of 4 µA maximum at +85°C. The SRAM supports flexible operating modes including byte read/write, page mode (32 Byte Page), and sequential mode, along with sequential read/write capabilities.
The 23K640-I/ST is housed in an 8-TSSOP package, suitable for surface mounting. It operates within an industrial temperature range of -40°C to 85°C. The device is Pb-Free and RoHS Compliant, and Halogen Free.
Key features include a HOLD pin for pausing communication, allowing the host to service higher priority interrupts without losing data. This makes it suitable for various embedded applications requiring reliable and efficient serial memory.
