AT29C512-15TC

Memory IC Overview

The AT29C512-15TC is a 5-volt only in-system Flash programmable and erasable read-only memory (PEROM) manufactured by Atmel. It provides 512K bits of storage organized as 65,536 words by 8 bits. The device features a maximum access time of 150 ns and operates within a commercial temperature range of 0°C to 70°C. It utilizes a single 5V ± 10% supply voltage and supports sector-based programming with hardware and software data protection mechanisms.

Memory IC Feature Summary

• Supports fast sector program operation with internal address and data latches for 128 bytes
• Includes hardware and software data protection features to prevent inadvertent writes
• Enables simple in-system reprogrammability without requiring high input voltages
• Provides data polling and toggle bit capabilities for end-of-program detection

Memory IC Applications

• In-system code storage and modification
• Data logging applications requiring nonvolatile storage
• Configuration parameter retention in embedded systems

Memory IC Procurement Notes

Verify the manufacturer designation, as this component originates from Atmel Corporation rather than Microchip Technology. Confirm the specific suffix 'TC' corresponds to the TSOP-32 package and commercial temperature rating. Ensure compatibility with existing system voltage levels, as the device requires a strict 5V supply.

Memory IC Selection Notes

Select this component when a 512K-bit Flash memory solution with sector erase capabilities is required. It is suitable for designs needing hardware write protection and low standby current. Note that the datasheet indicates this series is not recommended for new designs; consider evaluating newer alternatives if starting a fresh project.

Memory IC Part Context

This part belongs to the AT29C512 family of 5-volt Flash PEROMs. It shares architectural similarities with other densities in the series but offers specific capacity and sector organization. The device is designed for CMOS technology, ensuring low power consumption during active and standby modes while maintaining TTL-compatible inputs and outputs.
