DESCRIPTION
128Mb Async./Burst/Sync./A/D MUX
Winbond x16 ADMUX products are high-speed, CMOS pseudo-static random access memory developed for lowpower, portable applications. The device has a DRAM core organized. These devices are a variation of the industrystandard Flash control interface, with a multiplexed address/data bus. The multiplexed address and data functionality dramatically reduce the required signal count, and increase READ/WRITE bandwidth.
For seamless operation on a burst Flash bus, Winbond x16 ADMUX products incorporate a transparent self-refresh mechanism. The hidden refresh requires no additional support from the system memory controller and has no significant impact on device READ/WRITE performance.
Two user-accessible control registers define device operation. The bus configuration register (BCR) defines how the Winbond x16 ADMUX device interacts with the system memory bus and is nearly identical to its counterpart on burst mode Flash devices. The refresh...
