Description
This chip, the RTD2120, is a micro-processor designed for LCD monitors. It is equipped with the Designware DW8051, a 8051 core from Synopsys, making it compatible with other industry 8051 series. The chip also features a 96Kbyte FLASH with 8-bit bus, licensed from TSMC's 0.18um e-FLASH process. It is available in three package options: PLCC44, LQFP48, and QFP44. The chip can be used as a discrete MCU controller or integrated into a multi-chip package with our LCD monitor controller, reducing costs associated with packaging and PCB materials.
