24AA65/SM

The Microchip Technology 24AA65/SM is a smart 8K x 8 Serial Electrically Erasable PROM (EEPROM) designed for advanced, low-power applications. This device offers a memory capacity of 64Kbit and utilizes the industry-standard I2C compatible two-wire bus protocol.

Key electrical specifications include an operating voltage range of 1.8V to 6.0V, a maximum clock frequency of 400 kHz, and an access time of 900 ns. The EEPROM supports both byte and page write modes with a typical write cycle time of 2 ms. It features a 64-byte input cache for fast write loads and offers endurance ratings of up to 10,000,000 erase/write cycles for high endurance blocks and 1,000,000 cycles for standard endurance blocks. Data retention is rated at over 200 years.

This EEPROM is housed in an 8-pin SOIJ surface mount package, suitable for space-constrained designs. The operating temperature range is 0°C to 70°C (TA). The device also includes features like Schmitt Trigger filtered inputs for noise suppression and power-on/off data protection circuitry.

With its flexible features and robust performance, the 24AA65/SM is well-suited for applications requiring reliable non-volatile data storage in low-power environments.
