RTD2120-series

Overview

This chip is the micro-processor of LCD monitor. It uses the Designware DW8051 of Synopsys

as the 8051 core of this chip and is compatible with other industry 8051 series. Also, 96Kbyte

FLASH with 8 bit bus is embedded in this chip which is licensed from TSMC 0.18um e-FLASH

process. Here we use the package of PLCC44/LQFP48/QFP44 if we would like to have a discrete

MCU controller or we make a multi-chip package with our LCD monitor controller to form one

chip package to save the cost of package and PCB material.
