Preliminary W78E52B 8-BIT MTP MICROCONTROLLER GENERAL DESCRIPTION The W78E52B is an 8-bit microcontroller which can accommodate a wider frequency range with low power consumption.
The instruction set for the W78E52B is fully compatible with the standard 8051.
The W78E52B contains an 8K bytes MTP ROM (Multiple-Time Programmable ROM); a 256 bytes RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 4-bit I/O port P4; three 16bit timer/counters; a hardware watchdog timer and a serial port.
These peripherals are supported by eight sources two-level interrupt capability.
To facilitate programming and verification, the MTP-ROM inside the W78E52B allows the program memory to ...
