24AA08/P

Memory IC Overview

The Microchip Technology 24AA08/P is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz at voltages above 2.5V, and 100 kHz below 2.5V. The device features Industrial temperature range operation from -40°C to +85°C in an 8-Lead PDIP package.

Memory IC Feature Summary

• Supports bidirectional two-wire serial interface compatible with I2C protocols
• Includes hardware write-protect capability via the WP pin
• Features Schmitt trigger inputs for noise suppression
• Provides output slope control to eliminate ground bounce

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in industrial sensors

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the PDIP package type and Industrial temperature grade. Confirm the voltage operating range matches the system requirements, noting the 1.7V minimum for this device variant. Ensure compatibility with the host controller's I2C bus speed limitations.

Memory IC Selection Notes

Select this component when low standby current and wide voltage operation are required. The Industrial temperature range suits general-purpose applications. Consider alternative packages if surface-mount technology is preferred over through-hole mounting. Verify page write buffer size requirements against application data throughput needs.

Memory IC Part Context

This part belongs to the 24XX08 family of 8-Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC08B and 24FC08 devices but differs in voltage specifications and maximum clock frequencies. The family utilizes a standardized I2C interface for data access.

Memory IC Replacement Considerations

Direct substitutes include other 24AA08 variants with different package options such as SOIC or MSOP. Cross-family replacements like the 24LC08B require verification of the minimum operating voltage, as it starts at 2.5V compared to the 1.7V minimum of the 24AA08.
