MC80F7708
CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
WITH LCD CONTROLLER/DRIVER
1. OVERVIEW
1.1 Description
The MC80F7708 are an advanced CMOS 8-bit microcontroller with 8K bytes of FLASH ROM(MTP). This device is one of
the MC800 family and a powerful microcontroller which provides a high flexibility and cost effective solution to many LCD
applications. The MC80F7708 provide the following standard features: 8K bytes of FLASH ROM, 256 bytes of RAM, 20
bytes of segment LCD display RAM, 8/16-bit timer/counter, 10-bit A/D converter, 7-bit watch dog timer, 21-bit watch timer
with 7-bit auto reload counter, 8-bit UART, on-chip oscillator and clock circuitry. In addition, this device supports power
saving modes to reduce power consumption. So the MC80F7708 is the best controller solution in system which uses chara-
tered LCD display and ADC.
