Memory IC datasheet and documents for AT49BV320T-90TI

AT49BV320T-90TI

Memory IC Overview

The AT49BV320T-90TI is a 32-megabit (2M x 16 / 4M x 8) NOR Flash memory manufactured by Microchip Technology. It operates on a single voltage supply ranging from 2.65V to 3.3V. The device features an asynchronous access time of 90ns and supports sector erase architecture with individual write lockout capabilities. It includes a 128-bit protection register, suspend/resume functionality for erase and program operations, and hardware data protection mechanisms. The component is housed in a 48-lead TSOP package.

Memory IC Feature Summary

Sector Erase Architecture with individual write lockout for sixty-three 32K Word sectors and eight 4K Word sectors
Erase Suspend and Program Suspend features allowing interruption of operations to read or program other sectors
Hardware Data Protection via VPP pin control and power-on delays to prevent inadvertent programming
128-bit Protection Register with factory-programmed Block A and user-programmable Block B

Memory IC Applications

In-system programming applications requiring single voltage operation
Storage of secure boot code using sector lockdown features
Embedded systems utilizing asynchronous parallel flash memory interfaces

Memory IC Procurement Notes

Verify the specific suffix 'T' corresponds to the TSOP package and '90' indicates the 90ns speed grade as per the official datasheet. Confirm that the 'BV' designation aligns with the required 2.65V to 3.3V operating voltage range. Ensure compatibility with existing system designs regarding the 48-lead TSOP footprint and electrical specifications before procurement.

Memory IC Selection Notes

Select this component for designs requiring 32-megabit capacity with asynchronous parallel interface. It is suitable for applications needing sector-level erasure and hardware-based write protection. Consider the 90ns access time for timing constraints. Verify that the system can support the required VCC and VPP voltage levels for reliable program and erase operations.

Memory IC Part Context

This part belongs to the AT49BV/LV32X(T) family of 3-volt Flash memories. The manufacturer recommends using the AT49BV320A(T) or AT49BV322A(T) variants for new designs. The device is produced by Microchip Technology, which acquired Atmel, the original developer of this technology line.
