General Description
MLC822A is a cost effective, high performance
8-bit micro-controller of MEGAWIN. It
integrates an 8-bit pipeline CPU core, 48KB
ROM, 3072B RAM, two 8-bit timers, 660 dots
LCD driver, 10 I/O pins and other system
control circuits into a single chip. MLC822A
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 MLC822A provides a
build-in oscillator as clock source. It is suitable
for data bank product, hand-held game, toy
controllers and other products’ applications.
