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.
