Microchip's 8-Kbit 25XX080A/B and 16-Kbit 25XX160A/B are SPI bus-compatible serial EEPROM devices that have a maximum clock speed of 10 MHz, a write time of 5 ms, and a write current of 3 mA. These devices all feature self-timed Erase and Write cycles, built-in write protection, and high reliability with 200-year data retention and one million erase/write cycles. The devices are available in two voltage ranges (1,8-5,5 V and 2,5-5,5 V), and in both industrial temperature grade (-40 to +85°C), and extended temperature grade (-40 to +125°C) version. In addition, both 16- and 32-byte page sizes are available. Microchip's SEEVAL 32 Serial EEPROM Designer's Kit supports these devices assisting system integration and hardware/software debug. They are available in small packages, such as the MSOP, alongside standard packages.
