Supply original MX29F400CBMI-70G, Memory, by Macronix

GENERAL MX29LV320E T/B is a 32Mbit flash memory that can be organized as 4Mbytes of 8 bits each or 2Mbytes 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 64 equal 64 Kilo byte blocks. However, depending on the device being used as a Top-Boot or Bottom-Boot device, the top or the bottom frst block is further subdivided into 8 equal 8Kbyte blocks.
The outermost two sectors at the top or at the bottom can be protected at the boot blocks for this device. This flash memory also provides an additional factory lockable or customer lockable 256byte sector to provide security feature.
