Product details

Overview

The MA180028 is a PIC18F87K22 Plug-in Module (PIM) from Microchip Technology, designed as a direct replacement for the on-board PIC18F8722 on the PICDEM™ PIC18 Explorer Board. It enables rapid evaluation and firmware development for the PIC18F87K22 microcontroller-featuring 128 KB Flash, 4 KB RAM, 1.8–5.5 V operation, and integrated high-speed serial bootloader (AN1310)-in industrial control, sensor interface, and embedded prototyping applications.

For engineers reviewing the MA180028 datasheet, MA180028 pinout, MA180028 application, or MA180028 equivalent, this module supports voltage-configurable VDD (via R101/R102), 1:1 I/O mapping to J3/J5/J7/J11 PICtail™ connectors, MCLR reset configuration, and in-circuit emulation (ICE) mode activation via S4 switch-critical for secure bootloader deployment and mixed-voltage peripheral testing.

Technical Context

The MA180028 interfaces with the PICDEM PIC18 Explorer Board through a 3-pin female header aligned to the board's 3-pin riser, requiring S4 switch positioning to ICE mode to hold the original PIC18F8722 in reset. It modifies the board's regulator output to match PIC18F87K22 voltage requirements (1.8–5.5 V).

Pin compatibility is partial: most PICtail™ connector I/O lines map 1:1, but RF0 is unconnected (absent on PIC18F87K22), and VDD/VSS routing is adapted per DS51895A schematic. Bootloader firmware (AN1310) and demonstration firmware are preprogrammed for immediate UART-based reprogramming and feature validation.

FAQ

What is the primary function of the MA180028?

The MA180028 is a plug-in module that replaces the on-board PIC18F8722 on the PICDEM™ PIC18 Explorer Board, enabling evaluation and development with the PIC18F87K22 microcontroller. It adapts board voltage regulation, provides preloaded AN1310 bootloader firmware, and maintains compatibility with existing PICtail™ connectors-making MA180028 essential for legacy platform upgrades.

How does the MA180028 interface with the PICDEM PIC18 Explorer Board?

The MA180028 connects via a 3-pin female header that mates precisely with the board's 3-pin riser. Operation requires setting switch S4 to "ICE" to hold the original PIC18F8722 in reset. Power must be applied only after correct alignment and switch configuration-MA180028 relies entirely on this mechanical and logic-level handoff to function.

Does the MA180028 support configurable VDD voltage?

Yes. The MA180028 allows VDD adjustment from 1.8 V to 5.5 V by populating resistors R101 and R102 per the "Calculating Other VDD Values" section in the PICDEM™ PIC18 Explorer Demonstration Board User's Guide. This configurability ensures MA180028 operates correctly across the full PIC18F87K22 voltage range without hardware modification.

Is bootloader functionality preprogrammed on the MA180028?

Yes. The MA180028 ships with the AN1310 High-Speed Serial Bootloader preloaded, enabling UART-based firmware updates without an external PIC® programmer. Host software and documentation are available from Microchip's website-this eliminates dependency on dedicated debug tools during early-stage MA180028 development.

Which I/O pins are not supported when using the MA180028?

RF0 is left unconnected on the MA180028 because it does not exist on the PIC18F87K22 device. All other I/O pins connected to PICtail™ connectors J3/J5/J7/J11 maintain 1:1 mapping. Engineers must verify application logic excludes RF0 references to ensure reliable MA180028 operation.
