MEGAWIN MLC852A
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.
