AT29C010A-12TI

Memory IC Overview

The AT29C010A-12TI is a 5-volt-only in-system Flash programmable and erasable read-only memory (PEROM) manufactured by Microchip Technology. It provides 1 megabit of storage organized as 131,072 words by 8 bits. The device features a maximum access time of 120 ns and operates within an industrial temperature range of -40°C to +85°C. It utilizes a 32-lead Thin Small Outline Package (TSOP). Key electrical specifications include a typical active current of 50 mA and a standby current of 300 µA.

Memory IC Feature Summary

• Supports sector-based programming with 1024 sectors of 128 bytes each
• Includes hardware and software data protection mechanisms
• Features two 8K-byte boot blocks with independent lockout capabilities
• Provides DATA polling and toggle bit methods for end-of-program detection

Memory IC Applications

• In-system reprogrammable code storage
• Boot block applications requiring secure code locking
• Industrial embedded systems requiring wide temperature operation

Memory IC Procurement Notes

Verify the specific suffix 'TI' corresponds to the Industrial temperature grade (-40°C to +85°C) and the TSOP package type. Confirm that the datasheet revision matches the required specifications, noting the manufacturer's statement that this product family is not recommended for new designs. Ensure compatibility with 5V logic levels and check for any RoHS compliance updates on the official Microchip website.

Memory IC Selection Notes

Select this component when a 1-megabit nonvolatile memory solution with sector-level granularity is required. It is suitable for applications needing hardware data protection and boot block lockout features. Consider the 120 ns access speed and 5V-only supply requirement. Evaluate the TSOP package constraints against available board space and thermal requirements for industrial environments.

Memory IC Part Context

This part belongs to the AT29C010A series of 5-volt Flash memories from Atmel/Microchip. The series includes variants with different access times (70 ns, 90 ns, 150 ns) and packages (PLCC, PDIP, TSOP). The 'I' suffix denotes the industrial temperature range, while 'T' indicates the TSOP package. This series is designed for direct replacement of EPROMs in existing systems.

Memory IC Replacement Considerations

Compatible parts within the same series include AT29C010A-70TI, AT29C010A-90TI, and AT29C010A-15TI, which share identical pinouts and functionality but differ in access speed. Other package options like PLCC or PDIP are available with corresponding suffixes.
