The PIC18F1XK22/LF1XK22 family are 20‑pin microcontrollers offering up to 16 KB of flash program memory, 512 bytes of data RAM and 256 bytes of EEPROM. They operate from 1.8 V to 5.5 V and include a range of peripherals such as 8‑bit hardware multiplier, multiple timers, enhanced capture/compare/PWM modules, and an EUSART supporting RS‑232, RS‑485 and LIN 2.0.
The devices are available in PDIP, SSOP and SOIC packages and support a 64 MHz maximum clock frequency using an internal PLL. Detailed pin‑out tables, electrical characteristics, temperature ranges and package information are provided throughout the document. This manual is written in Chinese.
