Preliminary W78C33B 8-BIT MICROCONTROLLER GENERAL DESCRIPTION The W78C33B microcontroller supplies a wider frequency range than most 8-bit microcontrollers on the market. It is functional compatible with the industry standard 80C32 microcontroller series except the one extra 4-bit bit-addressable I/O port (Port 4). The W78C33B contains four 8-bit bidirectional parallel ports, three 16-bit timer/counters, and a serial port. These peripherals are supported by a six-source, two-level interrupt capability. There are 256 bytes of RAM, and the device supports ROMless operation for application programs. The W78C33B microcontroller has two power reduction modes, idle mode and power-down mode, both of which are software selectable.
