General Description
The Spansion S29VS256/128R and S29XS256/128R are MirrorBit® Flash products fabricated on 65 nm process technology.
These burst mode Flash devices are capable of performing simultaneous read and write operations with zero latency on two
separate banks using multiplexed data and address pins. These products can operate up to 108 MHz and use a single VCC of
1.7 V to 1.95 V that makes them ideal for the demanding wireless applications of today that require higher density, better
performance, and lowered power consumption. The S29VS256/128R operates in ADM mode, while the S29XS256/128R can
operate in the AADM mode.
