... TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic Firmware Built In Digital Servo The TC9457F is a firmware incorporating CD digital servo system. In addition to an LCD/LED driver, 4-channel 6-bit AD converters, and 2-wire/3-wire serial interface, it has a buzzer function, interrupt function, and 8-bit timer/counter. The CPU allows selection of the operating clock from three types of crystal oscillators (16 ...
