Advanced Micro Devices AM29BDS323D
The Am29BDS323 is a 32 Mbit, 1.8 Volt-only, simultaneous Read/Write, Burst Mode Flash memory device, organized as 2,097,152 words of 16 bits each. This device uses a single VCC of 1.7 to 1.9 V to read, program, and erase the memory array. The device can also be programmed in standard EPROM programmers.GENERAL DESCRIPTION
A 12.0-volt VPP may be used for faster program performance if desired. The Am29BDS323 provides a burst access of 20 ns at 30 pF with initial access times of 120 ns at 30 pF. The device operates within the industrial temperature range of –40°C to +85°C. The device is offered in the 47-ball FBGA package. requires Power Saving (PS), Ready (RDY), and Clock (CLK). This implementation allows easy interface with minimal glue logic to a wide range of microprocessors/microcontrollers for high performance read operations. The device offers complete compatibility with the JEDEC 42.4 single-power-supply Flash command set standard. Commands are written to the command register using standard microprocessor write timings. Reading data out of the device is similar to reading from other Flash or EPROM devices. The host system can detect whether a program or erase operation is complete by using the device status bit DQ7 (Data# Polling) and DQ6/DQ2 (toggle bits). After a program or erase cycle has been completed, the device automatically returns to reading array data.
