A 1.17 MB Microchip datasheet for the PIC16C9xx family, PIC16 microcontrollers with a built-in LCD driver module. The x characters stand for several family members differing in memory and features. Expect pinouts, LCD segment and common driver configuration, oscillator modes and electrical characteristics. A technician can use it to trace segment and backplane lines between controller and glass, check bias and supply pins, and confirm the chip type. As C-series parts are typically EPROM or OTP, reprogramming in place is usually not an option.
