Memory IC datasheet and documents for M58LR256KB70ZQ5E

M58LR256KB70ZQ5E

Memory IC Overview

The M58LR256KB70ZQ5E is a 256 Mbit (16 Mbit x 16) non-volatile Flash memory manufactured by Micron Technology Inc. It operates with a supply voltage range of 1.7 V to 2.0 V for both the core circuitry and I/O buffers, with an optional 9 V supply for fast programming. The device supports asynchronous random access read times of 70 ns and synchronous burst read modes at frequencies up to 66 MHz. It features a multiple bank architecture allowing dual operations, where program or erase activities in one bank do not interrupt reads in others. The component is housed in an ECOPACK-compliant TFBGA88 package measuring 8 x 10 mm.

Memory IC Feature Summary

Supports simultaneous program/erase operations in one bank while performing read operations in other banks without delay.
Features instant individual block locking with zero latency and absolute write protection via hardware signals.
Includes a unique 64-bit device number and user-programmable OTP cells within the Protection Register structure.

Memory IC Applications

Embedded systems requiring high-speed data storage with low power consumption
Firmware storage in portable electronic devices
Industrial control applications needing robust block-level data protection

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required speed grade and package type. Confirm the presence of the ZQ designation corresponds to the TFBGA88 package variant. Ensure compatibility with the 1.7 V to 2.0 V supply requirements during system design validation.

Memory IC Selection Notes

Select this component when a 256 Mbit capacity with a 16-bit interface is required. The 70 ns access time suits applications needing fast asynchronous retrieval. Consider the TFBGA88 package dimensions if board space is constrained. Verify that the system can support the necessary voltage levels for reliable operation.

Memory IC Part Context

This part belongs to the M58LR256KT/B series of 1.8 V Flash memories from Numonyx, now part of Micron Technology. The series includes variants with different access speeds and package options. The KB suffix indicates bottom parameter blocks, distinguishing it from the KT version which places them at the top.
