Revision A2
GENERAL DESCRIPTION
The W78E58 is an 8-bit microcontroller that is functionally compatible with the W78C58, except that
the mask ROM is replaced by a flash EEPROM with a size of 32 KB. To facilitate programming and
verification, the flash EEPROM inside the W78E58 allows the program memory to be programmed
and read electronically. Once the code is confirmed, the user can protect the code for security.
The W78E58 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, except
that one extra 4-bit bit-addressable I/O port(Port 4) and two additional external interrupts (
INT2
,
INT3 ).
The W78E58 contains four 8-bit bi-directional and bit-addressable I/O ports, three 16-bit
timer/counters, and a serial port. These peripherals are supported by a eight-source, two-level
interrupt capability. There are 256 bytes of RAM and an 32 KB flash EEPROM for application
programs.
The W78E58 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.
