Microchip Technology's AT25640B-TH-T is a 4K x 8 serial EEPROM designed for efficient data storage. This CMOS component operates over a wide supply voltage range, supporting 1.8V to 5.5V, with specific operation at 2.7V-5.5V and 4.5V-5.5V. It features a maximum clock frequency of 5MHz, enabling fast data transfer via the SPI serial bus. The memory density is 32 Kbits, organized as 4096 words of 8 bits each. Housed in a compact R-PDSO-G8 (TSOP2) package with a 0.65mm terminal pitch, it is suitable for surface-mount applications. The component offers a typical write cycle time of 5ms and operates across an industrial temperature range of -40°C to +85°C. Applications include industrial control, automotive, and consumer electronics requiring non-volatile data retention.
