Product details

Overview

AC244024 from Microchip Technology is a Processor Extension Pak (PEP) containing a debug header board with a pre-mounted PIC18LF14K50-ICE device, designed for in-circuit debugging of low-voltage 20-pin PIC18 microcontrollers. It supports 2.75V–3.6V operation, uses a 6-pin modular connector for tool interface, and enables full hardware debugging without consuming target I/O pins.

For engineers reviewing the AC244024 datasheet, AC244024 pinout, AC244024 application, or AC244024 equivalent, this PEP provides verified debug capability for PIC18LF14K50-based designs, integrates with MPLAB REAL ICE/ICD3/PICkit3 tools, and delivers production-aligned debug execution with factory-calibrated oscillator and bandgap settings.

Technical Context

The AC244024 implements a dedicated debug interface using the PIC18LF14K50-ICE silicon variant, which includes on-chip debug circuitry, dedicated debug memory, and two-wire ICD communication (ICDCLK/ICDDATA) plus VDD, VSS, and MCLR/VPP. It routes these signals from the -ICE device to both the debug tool (via 6-pin modular connector) and the target board (via 20-pin DIP socket).

This PEP operates within a strict 2.75V–3.6V supply range, matching the core voltage specification of the PIC18LF14K50-ICE device. Unlike standard programming, AC244024 is used exclusively for debugging in MPLAB X IDE - not for production programming - and preserves factory calibration bits for internal oscillator and bandgap reference.

Key Specifications

Parameter	Value and Actual Design Meaning
Product Type	Processor Extension Pak (PEP) - debug header assembly, not an IC or discrete component
Mounted Device	PIC18LF14K50-ICE - low-voltage, 20-pin Flash MCU with integrated debug module
Supply Voltage Range	2.75V–3.6V - matches VDDCORE spec of PIC18LF14K50-ICE; not 5V tolerant
Target Interface	20-pin DIP socket - mates directly with PDIP-packaged PIC18LF14K50 targets
Tool Interface	6-pin modular connector - standard interface for MPLAB REAL ICE, ICD3, and PICkit3
Debug Protocol	Two-wire ICD - uses ICDCLK and ICDDATA pins; requires no additional I/O on target
Calibration Retention	Factory bandgap & internal oscillator calibration bits preserved - ensures consistent timing across debug sessions

FAQ

What is the AC244024 used for?

The AC244024 is a Processor Extension Pak that provides in-circuit debugging capability for the PIC18LF14K50 microcontroller. It contains a debug header board with the PIC18LF14K50-ICE device pre-mounted and is used exclusively with Microchip debug tools (REAL ICE, ICD3, PICkit3) in MPLAB X IDE. The AC244024 enables full hardware debugging - including breakpoints, watchpoints, and register inspection - without occupying I/O pins on the target design.

Does the AC244024 support programming as well as debugging?

No, the AC244024 is designed solely for debugging and cannot be used for production programming. In MPLAB X IDE, it appears only under the Debug menu - not the Run menu. To program standard (non-ICE) PIC18LF14K50 devices, use tools like the MPLAB ICD3 or PICkit3 configured as programmers, or the Universal Programming Module (AC162049). The AC244024 itself loads only debug-executive firmware onto its onboard PIC18LF14K50-ICE device.

Which target devices does the AC244024 support?

The AC244024 is specifically intended for debugging the PIC18LF14K50 microcontroller in 20-pin PDIP packaging. It is listed in Microchip's DS50001292W specification as a required debug header for that device. While the header board may physically accept other 20-pin DIP devices, official support, signal routing, and debug feature compatibility are validated only for PIC18LF14K50-ICE operation per Microchip documentation.

What voltage range does the AC244024 operate within?

The AC244024 operates within a 2.75V–3.6V supply range, aligned with the VDDCORE specification of the onboard PIC18LF14K50-ICE device. This low-voltage range is mandatory - applying 5V risks damage or malfunction. Power must be supplied either by the connected debug tool (if capable) or externally to the header's VDD input, respecting the absolute maximum ratings defined for the PIC18LF14K50-ICE silicon.

Can the AC244024 be used with MPLAB X IDE?

Yes, the AC244024 is fully supported in MPLAB X IDE. During project creation, users select "AC244024" as the debug header product number in the Projects wizard and specify the attached debug tool (e.g., REAL ICE). Once configured, Debug > Debug Project initiates hardware debugging. The AC244024 requires no driver installation beyond standard Microchip tool drivers and relies on the IDE's built-in header configuration database for correct signal mapping and debug executive loading.
