AT49BV802A-70CI

Memory IC Overview

The AT49BV802A-70CI is an 8-megabit (512K x 16 or 1M x 8) NOR Flash memory manufactured by Microchip Technology. It operates on a single voltage supply ranging from 2.65V to 3.6V with a maximum access time of 70 ns. The device supports asynchronous parallel interfaces and features sector erase architecture comprising fifteen 32K-word sectors and eight 4K-word sectors. It offers low-power consumption with 12 mA active current and 13 µA standby current, alongside robust data protection mechanisms including sector lockdown and a 128-bit protection register.

Memory IC Feature Summary

• Sector Erase Architecture with individual write lockout for fifteen 32K-word and eight 4K-word sectors
• Erase Suspend and Program Suspend capabilities allowing read/write operations in non-suspending sectors
• Hardware Data Protection against inadvertent programming via VCC sense and power-on delay
• Common Flash Interface (CFI) support for standardized system software querying

Memory IC Applications

• In-system programming applications requiring single power supply operation
• Storage for secure boot code utilizing sector lockdown features
• Embedded systems requiring fast byte/word program times

Memory IC Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm the specific package variant (TSOP or CBGA) matches design requirements. Check for end-of-life status as the datasheet indicates this series may be discontinued. Ensure environmental compliance documentation aligns with project specifications.

Memory IC Selection Notes

Select based on required memory organization (x8 vs x16) and physical package constraints. Consider the availability of top or bottom boot block configurations depending on application needs. Evaluate the necessity of sector lockdown features for security requirements. Verify compatibility with existing system control signals such as CE, OE, and WE.

Memory IC Part Context

This component belongs to the AT49BV family of 3-volt Flash memories. It is part of Microchip's portfolio following the acquisition of Atmel Corporation. The device serves as a non-volatile storage solution for embedded applications requiring reliable data retention and flexible sector management.

Memory IC Replacement Considerations

Consult official Microchip Technology documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when evaluating alternatives.
