Microchip 64 kB EEPROM 80 ns 8-Pin SOP Serial-SPI AT25640B-XHL-B

Microchip AT25640B-XHL-B is a 64 kB electrically erasable programmable read-only memory (EEPROM) designed for various industrial and commercial electronic applications requiring low power consumption and low voltage operation. It comes in an 8-pin small outline package (SOP) with a slim 1.5 mm height profile, enabling compact PCB layouts.

This EEPROM device features a serial peripheral interface (SPI) compatible with SPI modes 0 and 3, allowing easy integration with microcontrollers and communication systems. It supports a maximum clock frequency of 20 MHz, providing fast access times with a maximum random access time of 80 ns.

The memory is organized as 8K x 8 bits, totaling 64 kilobytes, with 8 bits per word. The supply voltage range extends from 1.8 V to 5.5 V, accommodating various power schemes. Low supply current of approximately 10 mA enhances its suitability for battery-powered or low-power devices.

The device includes advanced write protection mechanisms such as a Write Protect (WP) pin and software instructions to disable writing. Its self-timed write cycles have a maximum duration of 5 milliseconds, enhancing operational efficiency.

With industrial-grade temperature tolerance ranging from -40 °C to 85 °C and RoHS compliance, this EEPROM offers long-term reliability featuring 100-year data retention and endurance of 1,000,000 write cycles. The device is optimized for embedded systems in industrial, commercial, and manufacturing environments.
