Microchip Technology MA180035

Overview

MA180035 from Microchip Technology is a 100-pin plug-in module (PIM) designed to interface the PIC18F66K80 8-bit microcontroller with the Automotive Networking Development Board (ADM00716). It integrates an ECAN™ module compliant with CAN 2.0B Active, supports up to 1 Mbps bit rate, and features a factory-preprogrammed demo firmware for CAN-based automotive networking evaluation.

For engineers reviewing the MA180035 datasheet, MA180035 pinout, MA180035 application, or MA180035 equivalent, this module serves as a hardware-ready platform for rapid prototyping of CAN-enabled embedded control systems - particularly in vehicle communication gateways, body electronics, and diagnostic interfaces where ECAN configuration flexibility and jumper-selectable I²C/SPI routing are critical.

Technical Context

The MA180035 implements the PIC18F66K80 MCU in a socketed 100-pin PIM form factor, enabling direct insertion into the ADM00716 board. It provides full access to the device's three CAN operating modes (Legacy, Enhanced, FIFO), six programmable TX/RX buffers, and sixteen 29-bit acceptance filters - all exposed via standardized header pins.

Hardware configurability includes four jumper headers (J1–J4) for selecting between SPI/I²C on RC3/RC4, and routing INT0/INT1 signals to multiple click headers. A 32.768 kHz crystal is mounted for secondary oscillator use, supporting low-power timing and RTC applications.

FAQ

What is the primary function of the MA180035?

The MA180035 is a 100-pin plug-in module that hosts the PIC18F66K80 microcontroller and enables its direct integration with the Automotive Networking Development Board (ADM00716). Its purpose is to simplify CAN protocol experimentation, firmware debugging, and hardware validation - not to serve as a standalone production component. The MA180035 includes jumpers, a 32.768 kHz crystal, and preloaded demo firmware to accelerate development cycles.

Does the MA180035 support both SPI and I²C interfaces simultaneously?

No - the MA180035 uses jumper headers J1 and J2 to select *either* SPI *or* I²C routing to the same physical pins (RC3 and RC4). By default, J1 connects RC4 to SDI (SPI mode), and J2 connects RC3 to SCK (SPI mode); moving jumpers to alternate positions reconfigures those pins for SDA/SDA and SCL/SCK respectively. This design prevents bus contention while allowing flexible peripheral interface testing on the same PIM.

Can the MA180035 be used without the Automotive Networking Development Board?

The MA180035 is mechanically and electrically designed for mating with the ADM00716 board and lacks onboard power regulation, programming circuitry, or debug interface connectors. While its pinout maps directly to the PIC18F66K80's 100-pin TQFP package, standalone use would require custom carrier hardware to provide VDD, MCLR, ICSP, and CAN transceiver connections - functionality not integrated into the MA180035 itself.

What CAN modes does the MA180035 enable through the PIC18F66K80?

The MA180035 exposes the full ECAN™ capability of the PIC18F66K80, supporting three distinct operational modes: Legacy mode (backward-compatible with older PIC CAN modules), Enhanced mode (with programmable TX/RX buffer sizes and priorities), and FIFO mode (for high-throughput message handling). All modes are accessible via firmware configuration - no hardware modification of the MA180035 is required to switch between them.

Is the MA180035 preprogrammed, and what firmware does it include?

Yes - the MA180035 ships with factory-preprogrammed demonstration firmware that initializes DIO, ADC, and CAN peripherals at 100 kbps (Fosc = 8 MHz), reads a potentiometer, toggles LEDs via CAN command (ID 0x700), and transmits periodic messages containing LED status, potentiometer value, and a receive counter.
