1. GENERAL DESCRIPTION
The W78C052D microcontroller supplies a wider frequency and supply voltage range than most 8-bit
microcontrollers on the market. It is compatible with the industry standard 80C52 microcontroller
series. The W78C052D contains four 8-bit bidirectional parallel ports, one extra 4-bit bit-addressable
I/O port (Port 4) and two additional external interrupts (
INT2
,
INT3
), three 16-bit timer/counters, one
watchdog timer and a serial port. These peripherals are supported by a eight-source, two-level
interrupt capability. There are 256 bytes of RAM and an 8K byte mask ROM for application programs.
The W78C052D microcontroller has two power reduction modes, idle mode and power-down mode,
both of which are software selectable. The idle mode turns off the processor clock but allows for
continued peripheral operation. The power-down mode stops the crystal oscillator for minimum power
consumption. The external clock can be stopped at any time and in any state without affecting the
processor.
