PIC18F65K40-E/MR

Microcontrollers Overview

The PIC18F65K40-E/MR is an 8-bit microcontroller featuring a PIC18 core with up to 32k bytes of Program Flash Memory, 2048 bytes of Data SRAM, and 1024 bytes of Data EEPROM. It operates at clock frequencies up to 64 MHz over the full voltage range of 2.3V to 5.5V. The device includes a 10-bit ADC with Computation (ADC2) supporting 45 external channels, a 5-bit DAC, three comparators, and a Zero-Cross Detect module. It provides 60 I/O pins in a 64-pin QFN package.

• Advanced touch sensing interfaces
• Industrial communication nodes

Microcontrollers Procurement Notes

Verify the specific suffix 'E' indicates industrial temperature range (-40°C to +85°C) and 'MR' denotes the 64-pin QFN package. Confirm RoHS compliance status through official Microchip documentation. Ensure the ordering part number matches the exact memory size and peripheral configuration required for your design.

Microcontrollers Selection Notes

Select this component when 32KB of program memory and 2KB of RAM are sufficient for the application logic. Choose this model over the PIC18F66K40 variant if lower memory capacity meets requirements while maintaining the same 64-pin footprint and peripheral set. Verify voltage supply constraints align with the 2.3V to 5.5V operating range.

Microcontrollers Part Context

This device belongs to the PIC18(L)F65/66K40 family of 64-pin, low-power, high-performance microcontrollers. It shares architectural similarities with other members like the PIC18F67K40 but offers distinct memory configurations. The family emphasizes XLP technology and integrated analog peripherals for versatile general-purpose use.

Microcontrollers Replacement Considerations

PIC18LF65K40-E/MR serves as the low-voltage version within the same package and feature set. Cross-referencing with PIC18F66K40-E/MR is possible if higher memory capacity is acceptable without changing the physical footprint.
