PIC18LF47K40-I/P

Microcontrollers Overview

The PIC18LF47K40-I/P is a 40-pin PDIP 8-bit microcontroller from the PIC18(L)F27/47K40 family. It features 128 KB of Flash program memory, 3615 bytes of SRAM, and 1024 bytes of EEPROM. The device operates at up to 64 MHz with an instruction cycle as low as 62.5 ns. It supports a supply voltage range of 1.8V to 3.6V and functions within industrial temperatures (-40°C to +85°C). Key peripherals include a 10-bit ADC with computation (ADCC), two comparators, a 5-bit DAC, Zero-Cross Detect, and multiple communication interfaces.

Microcontrollers Feature Summary

• Integrates eXtreme Low-Power (XLP) technology for optimized energy consumption in Sleep and active modes.
• Features a 10-bit Analog-to-Digital Converter with Computation (ADCC) that automates Capacitive Voltage Divider techniques for touch sensing and signal processing.
• Includes Core Independent Peripherals such as CWG, WWDT, CRC/Memory Scan, and ZCD to reduce CPU load.
• Provides Peripheral Pin Select (PPS) for flexible digital I/O mapping and configurable interrupt-on-change on all pins.

Microcontrollers Applications

• General-purpose embedded control systems requiring high performance and low power.
• Advanced touch sensing applications utilizing automated CVD techniques.
• Industrial monitoring and fault detection using Hardware Limit Timer and CRC modules.
• AC mains interfacing via Zero-Cross Detect functionality.

Microcontrollers Procurement Notes

Verify the specific suffix 'I/P' corresponds to the Industrial temperature range and PDIP package before ordering. Confirm the 'LF' designation indicates the lower voltage operating range (1.8V-3.6V) compared to the standard 'F' variant. Ensure compatibility with your system's power supply constraints and thermal requirements.

Microcontrollers Selection Notes

Select this component when 128 KB of Flash and 3615 bytes of RAM are required in a 40-pin DIP package. It is suitable for designs needing extensive analog capabilities like ADCC and ZCD. Consider the 1.8V-3.6V operating range if low-voltage operation is critical. Verify that the PDIP form factor meets your PCB assembly needs.
