PIC18F26K40-E/SP

Microcontrollers Overview

The PIC18F26K40-E/SP is a 28-pin SPDIP microcontroller from the PIC18(L)F26/45/46K40 family. It features 64 KB of Flash memory, 3615 bytes of SRAM, and 1024 bytes of EEPROM. The device operates at frequencies up to 64 MHz with an 8-bit RISC core. It supports voltage ranges of 1.8V to 3.6V (LF variant) or 2.3V to 5.5V (F variant). Key peripherals include a 10-bit ADC with computation, two comparators, a 5-bit DAC, and multiple communication interfaces.

Microcontrollers Feature Summary

• Integrates eXtreme Low-Power (XLP) technology for optimized energy consumption across various operating modes.
• Features a 10-bit Analog-to-Digital Converter with Computation (ADCC) that automates capacitive sensing techniques.
• Includes Core Independent Peripherals such as CWG, WWDT, CRC/Memory Scan, and Zero-Cross Detect.
• Supports flexible pin mapping through Peripheral Pin Select (PPS) for digital I/O configuration.

Microcontrollers Applications

• General-purpose embedded control systems
• Low-power industrial applications requiring extended temperature operation
• Touch sensing interfaces utilizing automated CVD techniques
• Battery-operated devices leveraging XLP sleep modes

Microcontrollers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +125°C) and '-SP' denotes the SPDIP package. Confirm the exact voltage rating by checking if the part number includes 'L' for low-voltage operation (1.8V-3.6V) or lacks it for standard operation (2.3V-5.5V). Ensure compatibility with your board's thermal requirements and physical footprint constraints.

Microcontrollers Selection Notes

Select this component when a balance of high performance and low power is required in a through-hole package. The inclusion of ADCC makes it suitable for touch applications without heavy CPU overhead. Consider the -E suffix for environments exceeding standard industrial temperatures. Evaluate the 64 KB Flash capacity against application code size requirements before finalizing the design.

Microcontrollers Part Context

This device belongs to the PIC18(L)F26/45/46K40 series, which shares a common architecture but varies in memory size and pin count. The 28-pin variants like the PIC18F26K40 offer a compact solution compared to the 40 or 44-pin models. It utilizes the enhanced PIC18 core with a 31-level hardware stack and programmable interrupt priorities.

Microcontrollers Replacement Considerations

PIC18LF26K40-E/SP offers identical functionality with a wider low-voltage operating range. PIC18F25K40-E/SP provides reduced memory resources (32 KB Flash, 2 KB RAM). PIC18F27K40-E/SP increases program memory to 128 KB while maintaining the same package and peripheral set.
