24AA08-I/P

Memory IC Overview

The Microchip Technology 24AA08-I/P is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 400 kHz at VCC levels between 2.5V and 5.5V, and 100 kHz when operating below 2.5V. The device operates on a single supply ranging from 1.7V to 5.5V and is housed in an 8-Lead PDIP package. It supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional data transmission via a two-wire serial bus protocol
• Includes hardware write-protect functionality controlled by the WP pin
• Features Schmitt trigger inputs for noise suppression on SDA and SCL lines
• Provides self-timed erase/write cycles with automatic page write buffering

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention for sensor modules
• Device identification and serial number storage

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm voltage compatibility with the system design, noting that maximum clock frequency varies based on the supply voltage level. Ensure the application circuit correctly handles the open-drain nature of the SDA line with appropriate pull-up resistors.

Memory IC Selection Notes

Select this component for applications requiring low-power operation down to 1.7V. Consider the 8-pin PDIP form factor for through-hole assembly processes. Evaluate the need for hardware write protection if security against accidental overwrites is critical. Verify that the host controller can support the required I2C timing constraints for the target supply voltage.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs, which includes variants like the 24LC08B and 24FC08. While sharing similar architectural features, these variants differ in minimum operating voltage and maximum clock speed specifications. The 24AA08 specifically targets low-voltage industrial applications within the standard I2C frequency range.

Memory IC Replacement Considerations

Direct substitutes include other 8Kbit I2C EEPROMs from the same manufacturer family, such as the 24AA08H or 24LC08B, provided voltage and speed requirements align. Cross-manufacturer replacements must be evaluated for pinout compatibility and electrical characteristic matching.
