CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
WITH LCD CONTROLLER/DRIVER
1. OVERVIEW
1.1 Description
The MC80X7208 is an advanced CMOS 8-bit microcontroller with 8K bytes of FLASH/ROM. This device is one of the
HMS800 and MC800 families and a powerful microcontroller which provides a high flexibility and cost effective solution
to many LCD applications. The MC80X7208 provides the following standard features: 8K bytes of FLASH/ROM, 256 bytes
of RAM, 27 nibbles of segment LCD display RAM, 8/16-bit timer/counter, 8-bit A/D converter, 7-bit watch dog timer, 8-bit
remote control carrier generator, 21-bit watch timer with 7-bit auto reload counter, on-chip oscillator and clock circuitry. In
addition, this device supports power down modes to reduce power consumption. So the MC80X7208 is the best controller
solution in system which charatered LCD display, ADC and battery backup. This document is only explained for the base of
MC80X7208, the compact functions are same as below.

5. PIN FUNCTION
VDD: Supply Voltage.
VSS: Circuit ground.
RESET: Reset the MCU Reset.
REMOUT: Signal output of an infrared remote controller.
XIN: Input to the inverting oscillator amplifier and input to
the internal main clock operating circuit.
XOUT: Output from the inverting oscillator amplifier.
SXIN: Input to the internal sub system clock operating cir-
cuit.
SXOUT: Output from the inverting subsystem oscillator
amplifier.
VCL0~VCL2: Power supply pins(bias) for the LCD driv-
er. The voltage on each pin is VCL2 > VCL1 > VCL0. See
"19. LCD DRIVER" on page 76 for details.
VLCDC: Booster reference voltage to drive LCD
CAPH, CAPL: Booster capacitor for voltage booster cir-
cuit to drive LCD.
VREG: Output of the voltage regulator for the sub clock os-
cillation circuit. Connect external 0.1uF capacitor to this
pin when using the sub system clock.
SEG0~SEG23, SEG32~SEG34: Segment signal output
pins for the LCD display. See "19. LCD DRIVER" on page
76 for details. Also SEG0~SEG23 are shared with a nor-
mal I/O ports and SEG32~34 are multiplexed with
COM3~COM1.
COM0~COM3: Common signal output pins for the LCD
display. See "19. LCD DRIVER" on page 76 for details.
SEG32~SEG34 and COM1~COM3 are selected by
LCDD[1:0] of the LCR register.
