MX29LA641DH

MX29LA641DH/L is a 64Mbit flash memory that can be organized as 8Mbytes of 8 bits each or as 4Mbytes of 16 bits
each. These devices operate over a voltage range of 2.7V to 3.6V typically using a 3V power supply input. The memory array is divided into 128 equal 64 Kilo byte blocks.

The MX29LA641DH/L is offered in a 64-ball BGA(LFBGA) JEDEC standard package. The package is offered in leaded, as well as lead-free version that is compliant to the RoHS specifications. The software algorithm used for this device also adheres to the JEDEC standard for single power supply devices. These flash parts can be programmed in system or on commercially available EPROM/Flash programmers.

Separate OE# and CEx (Output Enable and Chip Enable) signals are provided to simplify system design. When used
with high speed processors, the 90ns read access time of this flash memory permits operation with minimal time lost
due to system timing delays.

The automatic write algorithm provided on Macronix flash memories perform an automatic erase prior to write. The user only needs to provide a write command to the command register. The on-chip state machine automatically controls the program and erase functions including all necessary internal timings. Since erase and write operations take much longer time than read operations, erase/write can be interrupted to perform read operations in other sectors of the MX29LA641DH. For this, Erase Suspend operation along with Erase Resume operation are provided. Data# polling or Toggle bits are used to indicate the end of the erase/write operation.

The MX29LA641DH is manufactured at the Macronix fabrication facility using the time tested and proven MXIC advanced technology.

This proprietary non-epi process provides a very high degree of latch-up protection for stresses up to 100 milliamperes on address and data pins from -1V to 1.5xVCC.

With low power consumption and enhanced hardware and software features, this MX29LA641DH retains data reliably for at least ten years. Erase and programming functions have been tested to meet a typical specification of 100,000
cycles of operation.
