PIC18LF24K22-E/SO

Microcontrollers Overview

The PIC18LF24K22-E/SO is an 8-bit microcontroller from the PIC18(L)F2X/4XK22 family, manufactured by Microchip Technology. It features a high-performance RISC CPU with up to 16 MIPS operation and operates at frequencies up to 64 MHz using the internal PLL. The device includes 16 Kbytes of Flash program memory, 768 bytes of SRAM, and 256 bytes of Data EEPROM. It supports low-voltage operation from 1.8V to 3.6V and offers XLP technology for extreme power efficiency. The package is SOIC-28.

Microcontrollers Feature Summary

• Incorporates eXtreme Low-Power (XLP) technology with multiple sleep modes and alternate run modes to minimize power consumption.
• Features a flexible oscillator structure with a precision 16 MHz internal block, PLL, and fail-safe clock monitor.
• Includes analog peripherals such as a 10-bit ADC, two comparators, a DAC, and a Charge Time Measurement Unit (CTMU).
• Provides enhanced serial communication capabilities via two MSSP modules supporting SPI and I2C, and two EUSART modules.

Microcontrollers Applications

• Battery-powered consumer electronics requiring low standby current.
• Industrial control systems utilizing LIN bus or RS-232 communication.
• Capacitive touch sensing applications supported by the CTMU module.
• Motor control designs utilizing ECCP modules for PWM generation.

Microcontrollers Procurement Notes

Verify that the 'LF' designation confirms the 1.8V to 3.6V operating voltage range required for your specific application. Ensure the '-E' suffix indicates the extended temperature range if operation beyond commercial limits is needed. Confirm the '/SO' suffix matches the SOIC-28 surface-mount package requirement. Cross-reference the datasheet revision DS40001412H for any silicon errata relevant to this part number.

Microcontrollers Selection Notes

Select this component when a balance of moderate flash capacity and low power consumption is required in a compact 28-pin package. It is suitable for applications needing multiple serial interfaces and analog inputs without the complexity of higher pin counts. Consider the PIC18F24K22 variant if a wider 2.3V to 5.5V supply range is necessary instead of the lower voltage LF version.

Microcontrollers Part Context

This device belongs to the PIC18(L)F2X/4XK22 family, which shares core architecture and peripheral sets. Variations within the family differ primarily in memory sizes, I/O counts, and package options. The 'LF' prefix specifically denotes the low-voltage operational capability compared to the standard 'F' series devices.
