PIC18F67K40-I/PT

Microcontrollers Overview

The PIC18F67K40-I/PT is a 64-pin TQFP microcontroller from the PIC18(L)F67K40 family. It features 128 KB of Program Flash Memory, 3562 bytes of Data SRAM, and 1024 bytes of Data EEPROM. The device operates at frequencies up to 64 MHz with an instruction cycle as low as 62.5 ns. Operating voltage ranges from 2.3 V to 5.5 V, supporting industrial temperatures from -40°C to +85°C. It includes 47 external ADC channels, five CCP modules, two 10-bit PWMs, one CWG, three comparators, a 5-bit DAC, and a Zero-Cross Detect module.

Microcontrollers Feature Summary

• Integrates eXtreme Low-Power (XLP) technology for significant power reduction during operation through alternate run modes and peripheral disable capabilities.
• Features a 10-bit Analog-to-Digital Converter with Computation (ADCC) that automates signal analysis via averaging, filtering, oversampling, and threshold comparisons.
• Includes Core Independent Peripherals such as Complementary Waveform Generator (CWG), Windowed Watchdog Timer (WWDT), Cyclic Redundancy Check (CRC)/Memory Scan, and Peripheral Pin Select (PPS).
• Supports flexible clocking structures including High-Precision Internal Oscillator Block (HFINTOSC) up to 64 MHz and a Fail-Safe Clock Monitor.

Microcontrollers Applications

• General purpose applications requiring high performance and low power consumption.
• Advanced touch sensing systems utilizing Capacitive Voltage Divider (CVD) techniques.
• Industrial control systems requiring reliable data monitoring via CRC/Memory Scan.
• Applications needing AC signal detection using the Zero-Cross Detect (ZCD) module.

Microcontrollers Procurement Notes

Verify the specific suffix 'I/PT' corresponds to the Industrial temperature range (-40°C to +85°C) and TQFP-64 package. Confirm the 'F' designation indicates 5V support (2.3V to 5.5V) rather than the LF variant's 1.8V to 3.6V range. Ensure compatibility with required programming interfaces like ICSP or ICD.

Microcontrollers Selection Notes

Select this component when 128 KB of program memory and extensive analog peripherals are required in a 64-pin package. Consider the PIC18LF67K40 if the application operates strictly within the 1.8V to 3.6V range. Evaluate the need for Core Independent Peripherals to offload CPU tasks and reduce overall system power consumption.

Microcontrollers Part Context

This device belongs to the PIC18(L)F67K40 family, which combines large memory capacities with rich peripheral integration. The family shares identical core features except for variations in memory size, I/O count, and analog channel availability. The PIC18F67K40 represents the high-memory, 5V-tolerant option within the 64-pin configuration.

Microcontrollers Replacement Considerations

PIC18LF67K40-I/PT: Lower voltage range (1.8V-3.6V). PIC18F66K40-I/PT: Reduced memory (64KB Flash, 3.5KB RAM). PIC18F65K40-I/PT: Reduced memory and fewer analog channels.
