PIC18LF14K50-I/SS

Microcontrollers Overview

The PIC18LF14K50-I/SS is an 8-bit microcontroller from the PIC18(L)F1XK50 family, featuring a PIC18 core and SSOP-20 package. It provides 16 KB of Flash program memory, 768 bytes of SRAM, and 256 bytes of data EEPROM. The device supports a maximum operating frequency of 48 MHz with a voltage range of 1.8V to 3.6V. It includes a 10-bit ADC with 11 channels, USB 2.0 compliance, and multiple communication interfaces.

Microcontrollers Feature Summary

• Integrated USB 2.0 compliant Serial Interface Engine (SIE) supporting Full Speed and Low Speed modes with up to 16 endpoints.
• Extreme Low-Power (XLP) technology enabling deep sleep current as low as 24 nA and multiple idle run modes for power optimization.
• Flexible oscillator structure with a 16 MHz internal block, PLL, and fail-safe clock monitor for robust system timing.
• Enhanced Capture/Compare/PWM module providing auto-shutdown and auto-restart capabilities for motor control applications.

Microcontrollers Applications

• USB-enabled peripheral devices requiring full-speed or low-speed connectivity
• Battery-powered embedded systems utilizing XLP power management features
• Industrial controllers using LIN bus protocol support via EUSART
• Motor control applications leveraging ECCP PWM outputs

Microcontrollers Procurement Notes

Verify that the specific part number corresponds to the LF variant, which indicates operation within the 1.8V to 3.6V range, distinct from the F series. Confirm the -I suffix denotes industrial temperature rating and the /SS suffix specifies the SSOP-20 package. Ensure compatibility with development tools such as MPLAB ICD3 for programming.

Microcontrollers Selection Notes

Select this component when a balance of moderate memory capacity and integrated USB functionality is required in a compact 20-pin form factor. The LF designation is critical for designs operating below 3.0V. Consider the availability of the extended instruction set if optimizing C compiler re-entrant code performance is a priority.

Microcontrollers Part Context

This device belongs to the PIC18(L)F1XK50 family of 20-pin USB flash microcontrollers. It shares architectural similarities with the PIC18F14K50 but differs in operating voltage specifications. The family integrates high-endurance Flash memory and specialized peripherals like the SR latch and analog comparators into a single RISC-based controller.
