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.
