8-bit Microcontroller

The W78LE58 is an 8-bit Microcontroller which has an in-system programmable MTP-ROM for firmware updating. The instruction set of the W78LE58 is fully compatible with the standard 8052. The W78LE58 contains a 32K bytes of main MTP-ROM and a 4K bytes of auxiliary MTP-ROM which allows the contents of the 32KB main MTP-ROM to be updated by the loader program located at the 4KB auxiliary MTP-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 MTP-ROM inside the W78LE58 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user CAN protect the code for security. The W78LE58 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. By Winbond Electronics Corp America
