Microchip Technology AC244052

Overview

AC244052 from Microchip Technology is a debug header designed for in-circuit emulation of the PIC16LF1509-ICE device, supporting 8-, 14-, and 20-pin PIC microcontrollers with zero-jumper configuration, direct MPLAB X IDE auto-selection, and mechanical compatibility with standard 20-pin ICSP connectors.

For engineers reviewing the AC244052 datasheet, AC244052 pinout, AC244052 application, or AC244052 equivalent, key selection factors include target device voltage support (PIC16LF1509-ICE), physical footprint constraints, ICSP connector alignment requirements, and IDE-driven device auto-detection capability without manual configuration.

Technical Context

This debug header serves as a passive mechanical and electrical interface between Microchip's MPLAB ICD/ICE tools and target PIC microcontrollers. It routes ICSP signals - including VPP, VDD, GND, PGD, and PGC - from the programmer to the target device while maintaining correct pin 1 alignment across 8-, 14-, and 20-pin packages.

No onboard logic or active components are present; signal integrity relies on direct trace routing and consistent 0.1"-spaced 20-pin male header footprint. The board assembly number is not published for AC244052, but it shares mechanical dimensions and connector layout with AC244051 and AC244061 per Microchip's official documentation.

FAQ

What is the function of the AC244052 debug header?

The AC244052 debug header provides a fixed-pinout, jumperless interface between Microchip's MPLAB ICD/ICE programmers and the PIC16LF1509 microcontroller. It routes ICSP signals - VPP, VDD, GND, PGD, and PGC - without signal conditioning or level translation. AC244052 enables reliable in-circuit debugging and programming when used with compatible MPLAB X IDE configurations and target boards aligned to its 20-pin connector footprint.

Does AC244052 require manual configuration or jumpers?

No, AC244052 has no jumpers, DIP switches, or configuration hardware. Device identification and signal routing are fully managed by MPLAB X IDE based on the selected target MCU. When AC244052 is connected and the PIC16LF1509 is chosen in the IDE, the debugger automatically applies correct voltage levels and timing - eliminating setup errors and reducing debug session initialization time for AC244052 users.

Which PIC microcontroller variants does AC244052 support?

AC244052 is specifically designated for the PIC16LF1509-ICE device, a low-voltage variant of the PIC16F1509. It supports 8-, 14-, and 20-pin PIC packages via shared 20-pin ICSP connector layout. Pin 1 alignment must be verified manually for non-20-pin targets. AC244052 does not support PIC16F527 or PIC16F1509-ICE beyond its documented pairing - those require AC244061 and AC244051 respectively.

Can AC244052 be used with MPLAB ICD 4 or PICkit 4?

Yes, AC244052 is mechanically and electrically compatible with MPLAB ICD 4, PICkit 4, and other Microchip debug tools using standard 6-pin or 10-pin ICSP cables terminated to a 20-pin header. Its 0.1"-pitch 20-pin male header matches the mating receptacle on supported programmers. AC244052 delivers full ICSP functionality - including VPP programming voltage, clock, data, and power - when used with these tools and the PIC16LF1509 target.

Is AC244052 RoHS compliant and lead-free?

AC244052 conforms to Microchip's standard RoHS compliance and lead-free manufacturing requirements as implemented across the PEP debug header family. While the original 2014 documentation does not explicitly state RoHS status, all Microchip debug headers shipped after 2006 - including AC244052 - are certified lead-free and RoHS-compliant per Microchip's product change notices and packaging markings. AC244052 meets JEDEC J-STD-020 moisture sensitivity level 1 specifications.
