General Description

MLC852A is a cost effective, high performance

8-bit micro-controller of MEGAWIN. It

integrates an 8-bit pipeline CPU core, 64KB

ROM, 3328B RAM, two 8-bit timers, 1120 dots

LCD driver, 20 I/O pins and other system

control circuits into a single chip. MLC852A

build in an UART interface circuit, which could

be used to system link with other devices. An

e-flash interface is useful for the external

memory application. The MLC852A provides a

build-in oscillator as clock source. It is suitable

for data bank product, hand-held game, toy

controllers and other products’ applications.
