Microchip Technology, Inc. Memory AT25080A-10TU-1.8-T

The AT25080A-10TU-1.8-T is a serial electrically-erasable programmable read-only memory (EEPROM) with a capacity of 8 kilobits, organized as 1024 words of 8 bits each. It operates over a voltage range of 1.8V to 5.5V and supports SPI modes 0 and 3, with a maximum clock rate of 20 MHz at 5V. The device features a self-timed write cycle of up to 5 milliseconds and offers high reliability with an endurance of one million write cycles and data retention of up to 100 years. The AT25080A includes block write protection capabilities, allowing protection of 1/4, 1/2, or the entire memory array through hardware and software instructions. It is available in various package types, including 8-lead TSSOP, PDIP, and SOIC, making it suitable for space-constrained applications. The operating temperature range is from -55°C to +125°C, which is beneficial for industrial and automotive applications. However, it is noted that this product is not recommended for new designs.
