PIC32MX210F016B-I/SS 概述
A 32-bit microcontroller is an integrated circuit that combines a high-performance CPU core, volatile and non-volatile memory, programmable peripherals, and a rich interrupt subsystem on a single die. The PIC32MX family sits in the broader hierarchy of microcontroller -> embedded controller -> semiconductor, using the MIPS32 M4K instruction set to deliver 1.56 DMIPS/MHz while maintaining code density and deterministic interrupt latency suitable for real-time embedded systems.
Key features of the PIC32MX210F016B-I/SS include 19 general-purpose I/O pins, five 16-bit timers/counters, two I2C, two UART, and a parallel master port. The CTMU enables touch-sense and time-of-flight applications without external analog components, while the 4-channel DMA engine offloads the CPU in data-movement tasks. The on-chip USB 2.0 full-speed device controller with integrated transceiver simplifies connectivity for HID, CDC, and vendor-class peripherals.
The architecture pairs the M4K core with a 5-stage pipeline, branch predictor, and single-cycle multiply, which accelerates DSP and signal-processing workloads. Hardware-level support for PMP (Parallel Master Port) allows glueless connection to external graphics or memory-mapped peripherals, expanding its role beyond traditional MCU applications into low-cost audio and graphic HMI designs.
Typical applications include USB HID peripherals (keyboards, mice, custom input devices), capacitive touch user interfaces, low-cost graphics terminals, sensor hubs, and industrial control nodes. Designers frequently pair the PIC32MX210F016B-I/SS with Microchip's MCP2200 USB-UART bridge or the MCP2515 CAN controller to extend connectivity in mixed-protocol systems.
When designing with this MCU, ensure decoupling is placed within 5 mm of each VDD/VSS pair and that the 8 MHz internal oscillator is calibrated against the system clock domain for timing-sensitive USB enumeration. The compact 28-SSOP footprint suits cost-sensitive designs that need 32-bit throughput plus USB on the smallest PCB area.

典型应用
PIC32MX210F016B-I/SS 适用于 7 应用s: USB HID Peripherals, Capacitive Touch User Interfaces, Sensor Hubs and Data Loggers, Industrial Control Nodes, Low-Cost Graphics Terminals, Medical Point-of-Care Devices, Battery-Powered IoT Edge Nodes.
USB HID Peripherals
The PIC32MX210F016B-I/SS is well matched to USB Human Interface Device designs such as keyboards, mice, game controllers, and custom input devices. Its integrated USB 2.0 Full-Speed device controller with on-chip transceiver eliminates an external PHY, reducing BOM cost and freeing the 19 GPIO pins for key-matrix scanning or analog joysticks. With 16 KB Flash and 4 KB SRAM at 40 MHz, the MCU can run a USB HID bootloader plus a composite HID application stack, while the 4-channel DMA engine handles HID report FIFOs without CPU intervention.
推荐
Capacitive Touch User Interfaces
The integrated CTMU peripheral makes the PIC32MX210F016B-I/SS a strong fit for capacitive touch buttons, sliders, and proximity sensors. The CTMU supplies constant current to sense electrodes while the 10-bit 1 Msps ADC measures the resulting voltage, allowing 16-key touch panels to be scanned in software without an external analog front end. The 40 MHz M4K core executes the touch-decimation and noise-filtering algorithms in real time, and the small 28-SSOP footprint keeps the PCB area under 100 mm^2 for compact appliance and consumer panels.
推荐
Sensor Hubs and Data Loggers
The 10-bit 1 Msps ADC, 4-channel DMA, and I2C/SPI/UART connectivity on the PIC32MX210F016B-I/SS make it suitable for multi-sensor aggregation hubs that read temperature, pressure, and motion devices and stream data over USB CDC. The DMA offloads burst transfers while the CPU executes calibration and host-protocol stacks. With 16 KB Flash and 4 KB SRAM, designers can implement a small embedded file system in external EEPROM and a real-time clock interface for timestamping, satisfying battery-backed data logging requirements.
推荐
Industrial Control Nodes
In factory-automation nodes the PIC32MX210F016B-I/SS operates from 2.3 V to 3.6 V over the industrial -40C to +85C range. The UART and I2C ports drive sensor front ends, while the 5 timers handle PWM for valve and motor control up to 40 MHz peripheral clock. Brown-out detect, watchdog timer, and power-on reset support IEC 61508-style system-level reliability. USB CDC enables field firmware upgrades and diagnostics without a dedicated programmer.
推荐
Low-Cost Graphics Terminals
The PIC32MX210F016B-I/SS pairs the Parallel Master Port with external SRAM to drive small monochrome or color TFT panels for low-cost HMI terminals. The M4K core executes bit-blit operations fast enough to update 320x240 QVGA displays at 10 fps, while the DMA engine manages frame-buffer refresh in the background. USB allows configuration and firmware updates, and the 28-SSOP package keeps the controller footprint under 60 mm^2 on the main board.
推荐
Medical Point-of-Care Devices
For portable medical peripherals such as glucose meters, pulse oximeters, and spirometers, the PIC32MX210F016B-I/SS delivers 32-bit processing in a compact 28-SSOP footprint. The CTMU supports precision capacitance-based humidity and pressure sensing, the 10-bit ADC digitizes sensor outputs, and the USB device interface streams data to a host PC or tablet. The -40C to +85C industrial temperature range covers clinical and home-use environments without additional thermal compensation.
推荐
Battery-Powered IoT Edge Nodes
The PIC32MX210F016B-I/SS running from a 2.3 V to 3.6 V supply can be paired with a low-quiescent LDO and a 3.6 V Li-thionyl primary cell to build long-life IoT edge nodes. The peripheral-rich core wakes on USB attach or CTMU event, executes a sensing pass, and returns to sleep. USB enumeration is handled in firmware without external glue, simplifying the BOM and supporting field upgrades through the same USB port used for charging.

设计说明
Place a 10 uF bulk decoupling capacitor within 5 mm of each VDD pin pair (pins 7, 13, 27) and pair it with a 100 nF ceramic on each VDD/VSS adjacent pair for high-frequency noise suppression. According to the Microchip PIC32MX1XX/2XX datasheet, the on-chip 3.3 V regulator can supply up to 50 mA to external circuitry; reserve a dedicated 4.7 uF tantalum or ceramic at the VUSB pin (pin 18) when USB is enabled. A bulk 10 uF at the board input protects against USB hot-plug voltage transients.
Keep the D+ (pin 21) and D- (pin 20) traces matched within 0.5 mm and routed over a continuous ground plane to meet USB Full-Speed signal-integrity requirements. Place the 33 ohm series termination resistors within 5 mm of the MCU pins when using an external USB connector. The 28-SSOP 0.65 mm pitch requires careful solder-paste stencil aperture design: use a 0.4 mm aperture with 0.1 mm thickness to avoid solder bridges. The PGEC1/PGED1 pair (pins 10 and 11) should be reserved for the MPLAB ICD header with no series resistors in line.
Do not leave the VUSB pin floating when USB is unused - tie it to VDD through a 10 kohm resistor to disable the USB transceiver and reduce current by approximately 1 mA. According to the Microchip PIC32MX1XX/2XX datasheet, the device enters a low-power Sleep mode when the ON bit (OSCCON[15]) is cleared and the WAIT instruction is executed; ensure all peripherals are disabled before sleep to minimize quiescent current below 50 uA. Configuration bits must be set for the internal Fast RC oscillator and the correct WDT postscaler to avoid unintended resets on power-up.
