The 23K256-I/SN is a 256 Kbit low-power serial SRAM memory device from Quarktwin Technology Ltd., designed for use with a Serial Peripheral Interface (SPI). It operates within a supply voltage range of 2.7V to 3.6V and supports a maximum clock frequency of 20 MHz. The memory is organized as 32,768 x 8 bits and features a 32-byte page size, allowing for efficient data handling in various modes including byte read/write, page mode, and sequential mode. This device is characterized by low power consumption, with a read current of 3 mA at 1 MHz and a maximum standby current of 4 ¬µA at +85¬8C. It is available in multiple package types, including 8-lead PDIP, SOIC, and TSSOP, and is compliant with RoHS and halogen-free standards. The operating temperature ranges include industrial (-40¬8C to +85¬8C) and automotive (-40¬8C to +125¬8C), making it suitable for a variety of applications. The inclusion of a HOLD pin allows for communication pauses, enhancing its versatility in interrupt-driven environments.
