Microchip Technology MA330052

Overview

MA330052 from Microchip Technology is a dsPIC33CK64MC105 General Purpose Plug-In Module (PIM), designed for rapid evaluation and development of the dsPIC33CK64MC105 digital signal controller on the Explorer 16/32 Development Board. It features a 48-pin TQFP-mounted dsPIC33CK64MC105 DSC, 100-pin PIM connector, mikroBUS™ A/B interfaces, LCD control signals, analog sensor inputs (TC1047A), pushbuttons, LEDs, and on-board EEPROM support.

For engineers reviewing the MA330052 datasheet, MA330052 pinout, MA330052 application, or MA330052 equivalent, this module serves as a hardware reference platform to validate firmware, verify peripheral routing (SPI/I²C/UART/PWM/ADC), assess mikroBUS™ compatibility, and prototype control algorithms targeting motor control, power conversion, and embedded sensing applications.

Technical Context

The MA330052 implements a fixed hardware mapping between the dsPIC33CK64MC105's 48-pin TQFP package and a standardized 100-pin PIM interface compatible with the Explorer 16/32 base board. Signal routing prioritizes mikroBUS™ A/B (SPI, I²C, UART, PWM, INT, RST), LCD control (RS, RW, D4–D7, EN), analog inputs (potentiometer, temperature sensor TC1047A), and debug interfaces (ICSP™ PGC3/PGD3).

Not all dsPIC33CK64MC105 I/Os are exposed due to pin count constraints; only 62 of the device's total I/Os are routed to the PIM connector, with VDD/VSS distributed across 12 pins and key peripherals like PWM, ADC, comparator, and op-amp outputs selectively assigned to accessible nets such as P72_PWMA, P24_ANB, and P21_TEMP.

FAQ

What is the primary purpose of the MA330052?

The MA330052 is a General Purpose Plug-In Module that enables rapid evaluation and firmware development for the dsPIC33CK64MC105 digital signal controller. It mounts directly onto the Explorer 16/32 Development Board and exposes key peripherals-including mikroBUS™ interfaces, LCD control lines, analog sensors, and debug headers-allowing engineers to validate code, test signal routing, and prototype control algorithms without designing custom hardware. The MA330052 serves as an official reference platform from Microchip.

Which development boards is the MA330052 compatible with?

The MA330052 is specifically designed for use with the Explorer 16/32 Development Board (DM320001/DM320004). Its 100-pin PIM connector matches the board's PIM socket footprint and electrical pinout definition. It is not mechanically or electrically compatible with PICkit™, Curiosity, or other non-Explorer 16/32 platforms. Compatibility requires correct jumper configuration and power domain alignment per the DS50002916B Information Sheet.

Does the MA330052 include a debugger interface?

Yes, the MA330052 provides dedicated ICSP™ programming and debugging connections via pins P26_PGC3 and P27_PGD3, which route to the dsPIC33CK64MC105's PGD3/PGC3 pins. These signals are accessible through the 100-pin PIM connector and are intended for use with Microchip's MPLAB® ICD 4 or REAL ICE™ debuggers when the module is installed on the Explorer 16/32 board. No on-board debugger is integrated-the MA330052 relies on external debug tools.

What mikroBUS™ peripherals are supported by the MA330052?

The MA330052 supports both mikroBUS™ A and B sockets with full SPI (SCK/MISO/MOSI), I²C (SCL/SDA), UART (RX/TX), PWM, INT, and RST signals routed from the dsPIC33CK64MC105. Specifically: mikroBUS™ A includes P10_SCKA, P11_MISOA, P12_MOSIA, P14_CSA, P72_PWMA, P67_INTA, and P51_TXA/P52_RXA; mikroBUS™ B includes P53_MOSIB, P54_MISOB, P55_SCKB, P56_SDA, P57_SCL, P78_PWMB, P18_INTB, P19_RSTB, and P49_RXB/P50_TXB.

Can the MA330052 be used for LCD display interfacing?

Yes, the MA330052 provides complete 4-bit parallel LCD interface capability, including P44_LCDRS (Register Select), P81_LCDE (Enable), P82_LCDRW (Read/Write), and data lines P100_LCDD4, P3_LCDD5, P4_LCDD6, and P5_LCDD7. Six onboard LEDs (LED3–LED6, plus two additional) share these same port pins, but are configured as general-purpose outputs and do not interfere with LCD operation when properly initialized in software. The MA330052 schematic confirms direct connection to a standard HD44780-compatible display.
