23A640-I/P Description

Short technical summary and product information.

The Microchip Technology 23A640-I/P is a 64 Kbit Serial SRAM device designed for applications requiring fast, low-power memory access. It utilizes a Serial Peripheral Interface (SPI) compatible serial bus, requiring minimal pins for communication. The device supports flexible operating modes including byte read/write, page mode (32 Byte Page), and sequential mode, with a maximum clock frequency of 20 MHz.

This SRAM operates within a voltage range of 1.7V to 1.95V and features a memory organization of 8K x 8 bits. It is suitable for industrial applications with an operating temperature range of -40°C to 85°C (TA). The device is available in an 8-PDIP through-hole package, measuring 0.300 inches (7.62mm).

Key electrical characteristics include a read current of 3 mA at 1 MHz and a standby current of 4 µA maximum at +85°C, highlighting its low-power CMOS technology. The HOLD pin allows communication to be paused, enabling the host to service higher priority interrupts without losing data.

This component is designed for high reliability and is Pb-Free and RoHS Compliant, Halogen Free. Its SPI interface and compact package make it a versatile choice for embedded systems and data logging applications.
