General Description
The ST7FLCD1 is a microcontroller (MCU) from the
ST7 family with dedicated peripherals for LCD
monitor applications. The ST7FLCD1 is an industry
standard 8-bit core that offers an enhanced
instruction set. The 5V supplied processor runs
with an external clock at 24 MHz (27 MHz
maximum). Under software control, the MCU mode
changes to Wait mode thus reducing power
consumption. The enhanced instruction set and
addressing modes offer real programming
potential.
In addition to standard 8-bit data management, the
MCU features also include true bit manipulation,
8x8 unsigned multiplication and indirect addressing
modes.
The device gathers the on-chip oscillator, CPU,
60-Kbyte Flash, 2-KByte RAM, I/Os, two 8-bit
timers, infrared preprocessor, 4-channel Analog-to-
Digital Converter, 2 DDCs, I²C single master,
watchdog, reset and six 8-bit PWM outputs for
analog DC control of external functions.
