MCU
The Winbond W78E65 is an 8-bit microcontroller which has in-system programmable
FLASH EPROM for firmware updating. The instruction set of the W78E65 is fully
compatible with the standard 8052. The W78E65 contains a 64K bytes of main
FLASH EPROM to be updated by the loader program located at the 4KB auxiliary
FLASH EPROM; four 8-bit ib-directional and bit-addressable I/O ports; three 16-bit
timer/counters; a serial port. The W78E65 allows user to modify firmware by using
ISP function. Once the code is confirmed, the user can protect the code for security.
