Product details
Overview
MCP3901EV-MCU16 from Microchip Technology is an evaluation board designed to assess the performance of the MCP3901 dual-channel delta-sigma ADC and serve as a development platform for 16-bit PIC® MCU-based applications. It supports simultaneous 4 ksps sampling at 90 dB SINAD, integrates a dsPIC33FJ256GP710 PIM module, and enables real-time data acquisition via UART and USB interfaces for precision energy metering and sensor signal conditioning.
For engineers reviewing the MCP3901EV-MCU16 datasheet, MCP3901EV-MCU16 pinout, MCP3901EV-MCU16 application, or MCP3901EV-MCU16 equivalent, this board provides validated hardware reference for MCP3901 ADC integration with 16-bit MCUs, SPI-driven configuration, time/frequency/noise domain analysis tools, and Explorer 16-compatible PICtail™ Plus expansion.
Technical Context
The MCP3901EV-MCU16 implements a dual-channel analog front-end with differential inputs (CH0±, CH1±), configurable PGA gain, and two independent SINC3 digital filters. It uses either a 3.58 MHz external crystal or MCU-generated MCLK via Output Compare 1 (OC1) to drive the MCP3901's oversampling modulator.
Firmware on the dsPIC33FJ256GP710 handles DR-triggered SPI reads (24-bit conversion data per channel), UART communication at 115200 baud with ASCII-encoded buffer transmission, and real-time sampling speed measurement using Timer8/Timer9 as a 32-bit counter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Interface | SPI serial interface with CS, SCK, SDI, SDO signals - enables direct register-level control of MCP3901 configuration and conversion data readout. |
| Sampling Rate Support | Configurable up to 55 ksps dual-channel - achieved via OC1-generated MCLK or 3.58 MHz crystal, directly setting oversampling ratio in MCP3901 delta-sigma modulator. |
| Data Acquisition Path | DR-pin interrupt-driven SPI transfers - ensures deterministic timing capture of conversion completion and minimizes latency between sample and host receipt. |
| Host Communication | UART (115200 baud) + USB (with 512×8 SRAM buffer) - supports streaming raw ADC data and PC GUI synchronization without MCU firmware modification. |
| Hardware Compatibility | PICtail™ Plus connector and 100-pin PIM socket - allows plug-and-play integration with Explorer 16 and other high-pin-count PIC/dsPIC demo boards. |
| Analog Signal Conditioning | Dual differential input channels with jumper-selectable single-ended mode and burden resistor pads (R1–R4) - supports direct current transformer interfacing for metering applications. |

FAQ
What is the primary function of the MCP3901EV-MCU16 evaluation board?
The MCP3901EV-MCU16 evaluation board is a complete hardware platform for evaluating the MCP3901 dual-channel delta-sigma ADC and developing 16-bit MCU-based applications. It integrates a dsPIC33FJ256GP710 PIM module, supports configurable MCLK generation, provides differential analog inputs with burden resistor options, and delivers real-time ADC data to PC software via UART and USB interfaces - all within a 4-layer low-noise PCB layout optimized for precision measurement.
Which microcontrollers are pre-programmed and supported on the MCP3901EV-MCU16?
The MCP3901EV-MCU16 ships with two pre-programmed Plug-in Modules (PIMs): the dsPIC33FJ256GP710 and PIC24FJ128GA010. Both are configured to manage SPI communication with the MCP3901, generate MCLK via Output Compare 1, handle DR-triggered data acquisition, and transmit formatted ADC results over UART at 115200 baud - enabling immediate evaluation without firmware reprogramming.
Does the MCP3901EV-MCU16 support USB data streaming, and what is its implementation status?
The MCP3901EV-MCU16 includes USB hardware circuitry and a 512×8 SRAM buffer for high-speed data collection, but no USB firmware is supplied with the board. The onboard PIC18F86J55 microcontroller is blank and intended solely for user-developed USB firmware - meaning USB streaming requires custom firmware implementation, while UART remains the fully supported, out-of-box communication interface for the MCP3901EV-MCU16.
How does the MCP3901EV-MCU16 achieve precise timing for ADC sampling?
The MCP3901EV-MCU16 achieves precise ADC sampling timing through hardware-synchronized interrupt handling: the MCP3901's Data Ready (DR) pin triggers External Interrupt 3 on the dsPIC33, which initiates SPI read cycles to fetch 24-bit conversion data. Simultaneously, a 32-bit timer built from Timer8 and Timer9 measures elapsed time between first and last buffer samples - providing accurate, firmware-measured sampling rate validation for the MCP3901EV-MCU16.
What software tools are provided to interface with the MCP3901EV-MCU16?
The MCP3901EV-MCU16 is supported by Microchip's dedicated PC software tool, which provides a LabVIEW™-based GUI for configuring the MCP3901 (gain, phase, filter settings), visualizing acquired data in time domain (oscilloscope plot), frequency domain (FFT), and noise domain (histogram), plus statistical analysis of ADC performance metrics - all communicating with the MCP3901EV-MCU16 via UART at 115200 baud.
