Nexperia S29AS016J70BHIF40

The S29AS016J is a 16 Mbit, 1.8 Volt-only Flash memory organized as 2,097,152 bytes or 1,048,576 words with a x8/x16 bus and either top or bottom boot sector architecture. The device is offered in 48-pin TSOP and 48-ball FBGA packages. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device is designed to be programmed and erased in-system with the standard system 1.8 volt VCC supply. A 12.0VVPP or 5.0VCC are not required for program or erase operations. The device can also be programmed in standard EPROM programmers. The device offers access time of 70 ns allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls. The device requires only a single 1.8 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. The S29AS016J is entirely command set compatible with the JEDEC single-power-supply Flash standard. Commands are written to the command register using standard microprocessor write timings. Register contents serve as input to an internal state-machine that controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices. Device programming occurs by executing the program command sequence. This initiates the Embedded Program algorithm—an internal algorithm that automatically times the program pulse widths and verifies proper cell margin. The Unlock Bypass mode facilitates faster programming times by requiring only two write cycles to program data instead of four. Device erasure occurs by executing the erase command sequence.
