AT49BV6416C-70CI

Memory IC Overview

The AT49BV6416C-70CI is a 64-megabit (4M x 16) NOR Flash memory manufactured by Microchip Technology. It operates on a single 2.7V to 3.6V power supply with asynchronous access times of 70 ns and page mode read times of 20 ns. The device features a four-plane organization allowing concurrent read operations in planes not being programmed or erased. It includes sector erase architecture with individual write lockout, suspend/resume capabilities for program and erase cycles, and low-power consumption of 30 mA active and 25 µA standby. The component utilizes a CBGA package and supports Common Flash Interface (CFI).

Memory IC Feature Summary

• Four-plane memory organization enabling concurrent read operations while other planes are undergoing programming or erasing.
• Sector erase architecture with eight 4K-word sectors and 127 32K-word main sectors, each featuring individual write lockout.
• Erase and program suspend/resume functionality allowing interruption of operations to read or program data from other sectors.
• Hardware data protection mechanisms including VCC sense, power-on delay, noise filters, and VPP control.

Memory IC Applications

• In-system programming applications requiring single-voltage operation.
• Systems utilizing Common Flash Interface (CFI) for standardized device configuration queries.
• Embedded storage solutions requiring flexible sector protection modes such as Softlock and Hardlock.

Memory IC Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Confirm current availability status as legacy components may have limited supply. Ensure compatibility with system voltage levels and interface requirements before procurement.

Memory IC Selection Notes

Select this component for designs requiring high-performance parallel NOR flash with multi-plane concurrency. Consider the CBGA package constraints and pin configuration during PCB layout. Evaluate the need for hardware write protection features and sector locking capabilities when designing secure storage architectures.

Memory IC Part Context

This part belongs to the AT49BV series of 3-volt Flash memories produced by Microchip Technology following its acquisition of Atmel. The series is characterized by single-voltage read/write operations and support for both asynchronous and page mode accesses. It serves as a nonvolatile memory solution for embedded systems requiring reliable data retention and fast access speeds.

Memory IC Replacement Considerations
