The 23A640-I/P is a 64 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 1.5V to 1.95V and supports a maximum clock frequency of 20 MHz. The memory is organized as 8192 x 8 bits and features a 32-byte page size for efficient data handling. 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 includes a HOLD pin for pausing communication, allowing the host to manage higher priority tasks without losing data integrity. The 23A640-I/P is available in various package types, including 8-lead PDIP, SOIC, and TSSOP, and is compliant with RoHS and halogen-free standards. The operating temperature range for the industrial version is -40¬8C to +85¬8C, while the automotive version supports -40¬8C to +125¬8C, making it suitable for a variety of applications. The device also features ESD protection on all pins rated at 2 kV, enhancing its reliability in demanding environments.
