Description

The SB80C196NU is a member of Intel’s 16-bit MCS® 96 microcontroller family. It features 1 Mbyte of linear address space, a demultiplexed bus, and a chip-select unit. The external bus can dynamically switch between multiplexed and demultiplexed operation. When operating at 25 MHz in demultiplexed mode, the SB80C196NU can access a 100 ns memory device with zero wait states. The SB80C196NU is available without ROM (80C196NP) or with 4 Kbytes of ROM (83C196NP).
