The PIC18F14K50-I/SS from Microchip Technology is an 8-bit PIC® microcontroller designed for embedded applications requiring integrated USB connectivity. It includes 16KB of Flash program memory, 768 bytes of RAM and 256 bytes of data EEPROM, with an internal clock system capable of operating at up to 48MHz.
The PIC18F14K50 integrates a USB 2.0-compliant interface supporting both Low-Speed and Full-Speed USB operation. It supports Control, Interrupt, Isochronous and Bulk transfer types, with up to 16 endpoints or eight bidirectional endpoints, along with automatic detection of a physical USB host connection.
The device provides up to 15 I/O pins, a 9-channel 10-bit ADC, two analog comparators and up to five PWM outputs. Serial interfaces include SPI, I²C and enhanced USART, with support for applications using RS-232, RS-485 and LIN 2.0 communication.
Additional features include an enhanced watchdog timer, programmable brown-out reset, power-on reset, oscillator fail-safe operation and multiple power-managed modes. The device supports an operating-voltage range of approximately 1.8V to 5.5V and includes a single-cycle 8 × 8 hardware multiplier and interrupt-priority support.
The PIC18F14K50-I/SS is supplied in a 20-pin SSOP surface-mount package, with the “I” option indicating the industrial temperature grade. Microchip currently lists the PIC18F14K50 family as In Production.
