MX29L1610T

The MX29L1610T/B is a 16 Mbit, 3 V-only Flash memory organized as a either 1 Mbytesx16 or 512K word x32.For flexible erase and program capability, the 16 Mbits of data is divided into 35 sectors of one 16 Kbyte block,two 8 Kbyte parameter blocks, one 32 Kbyte main block,and thirty-one 64 Kbyte main blocks. To allow for simple in-system operation, the device can be operated with single 2.7 V to 3.6 V supply voltage. Since many designs read from the flash memory a large percentage of the time, significant power saving is achieved with the 2.7 V VCC operation. Manufactured with MXIC's advanced nonvolatile memory technology, the device offers access times of 90 ns.

The MX29L1610T/B command set is compatible with the JEDEC single-power-supply flash standard. Commands are written to the command register using standard microprocessor write timings. MXIC's flash memory augments EPROM functionality with an internal state machine which controls the erase and pro-
gram circuitry. The device Status Register provides a convenient way to monitor when a program or erase cycle is complete, and the success or failure of that cycle.

Programming the MX29L1610T/B is performed on a page basis; 128 bytes of data are loaded into the device and then programmed simultaneously. The typical Page Program time is 5ms.The device can also be reprogrammed in standard EPROM programmers. Reading data out of the device is similar to reading from an EPROM or other flash.

Erase is accomplished by executing the Erase command sequence. This will invoke the Auto Erase algorithm which is an internal algorithm that automatically times the erase pulse widths and verifies proper cell margin.This device features both chip erase and block erase.Each block can be erased and programmed without affecting other blocks. Using MXIC's advanced design technology, no preprogram is required (internally or ex-ternally). As a result, the whole MX29L1610T can be typically erased and verified in as fast as 200 ms.
