The AT25128AN-10SI-2.7 is a 128Kbit EEPROM memory device from Quarktwin Technology Ltd., designed for applications requiring low-power and low-voltage operation. It operates within a voltage range of 2.7V to 5.5V and supports a maximum clock rate of 20 MHz. The device features a Serial Peripheral Interface (SPI) that is compatible with modes 0 and 3, allowing for efficient data communication. This memory chip is organized as 16,384 words of 8 bits each and supports both byte and page write operations with a self-timed write cycle of up to 5 ms. It includes block write protection options, enabling protection of 1/4, 1/2, or the entire memory array. The AT25128AN-10SI-2.7 also incorporates hardware and software data protection mechanisms, including a write protect (WP) pin. The device is rated for high reliability, with an endurance of 100,000 write cycles and a data retention period exceeding 100 years. It is available in multiple package types, including 8-lead SOIC, making it suitable for various industrial and commercial applications. The operating temperature range is from -40¬8C to +85¬8C, with extended temperature options available.
