1. General
Description
The TP8511KB is an 8-bits microcontroller that can operate in wide range of power
supply. The TP8511KB contains four 8-bit bi-directional parallel ports, two 16-bit
timer/counters, and three direct LED drivers. These peripherals are supported by a two-source,
two-level interrupt capability. The internal memory includes 128 bytes of RAM for data
memory and 4K bytes of ROM for program memory.
