Revision A3
0GENERAL DESCRIPTION
The W78E52 is an 8-bit microcontroller that is functionally compatible with the W78C52, except that
the mask ROM is replaced by a flash EEPROM with a size of 8 KB.
To facilitate programming and verification, the flash EEPROM inside the W78E52 allows the program
memory to be programmed and read electronically. Once the code is confirmed, the user can protect
the code for security.
The W78E52 microcontroller supplies a wider frequency range than most 8-bit microcontrollers on the
market. It is functionally compatible with the industry-standard 80C52 microcontroller series.
The W78E52 contains four 8-bit bidirectional and bit-addressable I/O 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 an 8 KB flash EEPROM for application programs.
The W78E52 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.
