NEW PRODUCT ANNOUNCEMENT
GMS81C4040/87C4060
8-BIT CMOS SINGLE CHIP MICROCONTROLLER
INTRODUCTION :
GMS81C4040/87C4060 is a single chip microcomputer designed with CMOS
silicon gate technology.
It is housed in a 52-pin shrink plastic molded DIP. This single chip microcomputer
is useful for the high-tech channel selection system for TV.
WHAT IS IT?
The GMS81C4040/87C4060 is based on the GMS800 Series 8-bit CPU core.
In addition to such basic components as ROM(EPROM), RAM, and I/O ports,
they integrate on the single chip on-screen display function, I2C bus interface,
14-bit PWM generator for controlling a tuner, remote signal receiving circuit,
A/D converter, and watchdog timer.
