AT49BV163D-70TU-T

Memory IC Overview

The AT49BV163D-70TU-T is a 16-megabit (1M x 16/2M x 8) NOR Flash memory manufactured by Microchip Technology. It operates on a single voltage supply ranging from 2.65V to 3.6V and features a fast read access time of 70 ns. The device supports sector erase architecture with individual write lockout capabilities for 31 large sectors and 8 small sectors. It includes suspend/resume functionality for both program and erase operations, allowing concurrent access to other memory regions. The component utilizes a parallel interface and is housed in a 48-lead TSOP package.

Memory IC Feature Summary

• Sector Erase Architecture with Individual Write Lockout
• Erase and Program Suspend/Resume Capability
• Hardware Data Protection and Sector Lockdown
• Common Flash Interface (CFI) Support

Memory IC Applications

• In-system programming applications
• Code storage requiring boot block protection
• Embedded systems needing sector-level data security
• Industrial control firmware storage

Memory IC Procurement Notes

Verify the specific ordering suffix 'T' against official Microchip documentation to confirm tape-and-reel packaging status. Ensure the voltage range matches system requirements as this device is strictly 3-volt only. Confirm pin compatibility with the 48-lead TSOP footprint before integration.

Memory IC Selection Notes

Select this component when a 16-megabit density with 70 ns access speed is required. It is suitable for designs needing flexible sector protection and suspend features. Verify that the host system supports the necessary command sequences for sector lockdown and CFI queries.

Memory IC Part Context

This part belongs to the AT49BV series of 3-volt Flash memories. It shares architectural similarities with other devices in the family but offers specific sector configurations and timing characteristics. The manufacturer transitioned from Atmel to Microchip Technology, maintaining the product lineage.

Memory IC Replacement Considerations

Check for AT49BV163DT variants if CBGA packaging is preferred over TSOP. Verify electrical equivalence with other 16Mbit 3V Flash parts from the same manufacturer before substitution.
