MX29LV160DBXEI-70G

MX29LV160DT/B is a 16Mbit flash memory that can be organized as 2Mbytes of 8 bits each or as 1Mwords 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 32 equal 64 Kilo byte blocks. However, depending on the device being used as a Top-Boot or Bottom-Boot device. The outermost one sector at the top or at the bottom are respectively the boot blocks for this device. The MX29LV160DT/B is offered in a 48-pin TSOP, 48-ball XFLGA/WFBGA and a 48-ball CSP(TFBGA) JEDEC standard package. These packages are offered in leaded, as well as lead-free versions that are 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 CE# (Output Enable and Chip Enable) signals are provided to simplify system design. When used with high speed processors, the 70ns 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 device. 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.
