24AA01HT-I/LT

Memory IC Overview

The Microchip Technology 24AA01HT-I/LT is a 1 Kbit (128 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 of up to 8 bytes with a typical write cycle time of 3 ms. The component is housed in a SC-70-5 package and is rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Hardware write-protect capability allows locking the upper half of the memory array via the WP pin.
• Schmitt trigger inputs and output slope control provide noise suppression and eliminate ground bounce.
• Supports acknowledge polling to maximize bus throughput during internal write cycles.
• Includes VCC threshold detection to disable erase/write logic if power drops below nominal levels.

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial instrumentation with noisy signal environments
• Battery-powered devices utilizing minimal standby current
• Consumer electronics needing compact surface-mount memory solutions

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement. Ensure the design accommodates the SC-70-5 footprint dimensions and electrical characteristics defined in the datasheet.

Memory IC Selection Notes

Select this component when a 1 Kbit EEPROM is required with a 5-lead SC-70 package. It is suitable for applications operating down to 1.7V, unlike the 2.5V minimum 24LC01BH variant. Consider the hardware write-protect feature if partial array security is necessary within the design constraints.

Memory IC Part Context

This part belongs to the 24AA01H/24LC01BH family of 1 Kbit serial EEPROMs. It shares functional similarities with other members like the 24AA01HT-I/SN but differs in physical packaging. The 'HT' suffix indicates tape and reel availability, while 'LT' specifies the SC-70-5 package configuration.

Memory IC Replacement Considerations

The 24AA01HT-I/SN serves as a direct alternative offering identical electrical specifications in an 8-SOIC package. Designers must verify PCB layout compatibility due to the difference in pin count and physical dimensions between the SC-70-5 and SOIC packages.
