The 83C196LC, 83C196LD are low-cost, pin-compatible replacements for the existing 87C196JT and 87C196JR, respectively. These products feature an enhanced synchronous serial I/O (SSIO) port for more flexible communication to other devices. The enhanced SSIO is compatible with Motorola’s Serial Peripheral Interface (SPI) protocol and National’s Microwire protocol. To optimize die size, the A/D converter was removed for use in those applications that use an off-chip A/D converter.
