The Microchip Technology AT25640B-PU is a 4K x 8 serial EEPROM utilizing CMOS technology. This device operates within a wide supply voltage range, supporting 1.8V to 5.5V, with specific operation modes at 2.7V-5.5V and 4.5V-5.5V. It features an SPI serial interface capable of clock frequencies up to 5 MHz. The memory organization is 4K words by 8 bits, providing a total density of 32 Kbits. Designed for through-hole mounting, it is housed in an 8-lead PDIP package (R-PDIP-T8) with a 2.54mm terminal pitch. The AT25640B-PU operates across a temperature range of -40°C to +85°C and is suitable for industrial and consumer electronics applications requiring non-volatile data storage.
