The PIC18F6X7X/8X7X is Microchip's latest 16-bit Flash microcontroller family. This series of products offers high performance, low power, multiple peripherals and rich software resources, making it the ideal embedded control chip.
The PIC18F6X7X/8X7X series integrates two independent 16‑bit Σ‑Δ ADCs with programmable gain, a 10‑bit ADC offering up to 8 channels, and programmable‑VREF comparators. It also includes an LCD driver capable of directly driving panels with up to 44 segments and 112‑176 pixels, even while the device is in sleep mode.
Key peripherals include a real‑time clock with calendar, master synchronous serial port supporting SPI and I²C, two USART modules, four 8/16‑bit timers/counters, and four capture/compare/PWM modules. Low‑power features comprise multiple oscillator modes, PLL options, brown‑out reset, watchdog timer, and extensive flash and EEPROM endurance specifications. This manual is written in Chinese.
