1. GENERAL DESCRIPTION
The W78L058A is an 8-bit microcontroller which has an in-system programmable Flash EPROM for
firmware updating. The instruction set of the W78L058A is fully compatible with the standard 8052.
The W78L058A contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the
contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary
ROM; 512 bytes of on-chip RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional
4-bit port P4; three 16-bit timer/counters; a serial port. These peripherals are supported by a eight
sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the
W78L058A allows the program memory to be programmed and read electronically. Once the code is
confirmed, the user can protect the code for security.
The W78L058A 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.
