24AA08H-I/P

Memory IC Overview

The Microchip Technology 24AA08H-I/P is an 8 Kbit (1K x 8) Electrically Erasable PROM featuring a 2-Wire I2C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, drawing a maximum read current of 1 mA and standby current of 1 µA. It supports page writes up to 16 bytes with a typical write cycle time of 3 ms. The component is housed in an 8-lead PDIP package and is rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Self-timed erase/write cycles with acknowledge polling support for bus throughput optimization

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Low-voltage embedded controllers utilizing I2C communication
• Applications necessitating hardware-level write protection for critical data segments

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range (-40°C to +85°C) and 'P' denotes the 8-lead PDIP package. Confirm RoHS compliance status as per the latest datasheet revision. Ensure the design accounts for the 1.7V minimum operating voltage characteristic of the H-series devices compared to standard variants.

Memory IC Selection Notes

Select this part when a low-voltage EEPROM is required that supports operation down to 1.7V. The industrial grade rating makes it suitable for broader environmental conditions than commercial parts. The 8-pin PDIP package facilitates through-hole prototyping and assembly. Verify that the 400 kHz I2C speed meets the system's timing requirements.

Memory IC Part Context

This component belongs to the 24AA08H/24LC08BH family of 8 Kbit serial EEPROMs. The 'H' designation indicates support for lower voltage operation starting at 1.7V, distinguishing it from the 2.5V minimum 24LC08BH variant. The 'I' suffix specifies the industrial temperature range, while 'P' identifies the physical package type.

Memory IC Replacement Considerations

The 24LC08BH serves as a functional substitute but requires a minimum supply voltage of 2.5V. Other 8 Kbit I2C EEPROMs may differ in voltage ranges or package types. Verify electrical compatibility before substitution.
