S93C66B Overview
It is organized as 64-word × 16-bit, 128-word × 16-bit, 256-word × 16-bit, respectively. Each is capable of sequential read, at which time addresses are automatically incremented in 16-bit blocks. The instruction code is patible with the NM93CS46/56/66.
S93C66B Key Features
- Wide operating voltage range
