MPN: PIC32MX210F016BT-I/ML ✓ Hoạt độngPIC32MX210F016BT-I/ML Tóm tắt
A 32-bit microcontroller (MCU) is a microprocessor-based controller whose data path, registers and ALU are 32 bits wide, enabling higher throughput, larger addressable memory and richer peripherals than 8-bit or 16-bit MCUs. PIC32MX devices sit in the power-management IC family hierarchy as low-power MCU SoCs that combine a CPU core, on-chip memory, timers, communication peripherals and analog blocks into a single chip. The MIPS32 M4K core used here is a Harvard-architecture RISC core widely deployed in PIC32MX1xx/2xx/3xx/4xx/5xx/6xx/7xx families.
Key features include 16 KB Flash, 4 KB SRAM, 40 MHz maximum CPU speed, 10-bit ADC with up to 10 channels, two UART modules, two I2C modules, two SPI modules, five 16-bit timers/counters, and Peripheral Pin Select (PPS) for flexible signal routing. The device integrates separate PLLs for CPU and USB clocks, USB 2.0 full-speed device/host/OTG, and configurable power management modes for energy-constrained designs.
The architecture relies on a single-cycle multiply unit, a hardware DMA engine (up to 4 channels with automatic data-size detection) and an internal 8 MHz oscillator with PLL multiplication. The exposed pad on the QFN package provides a low-thermal-resistance path, while the 32-bit MIPS core delivers 1.56 DMIPS/MHz performance, suiting control loops and protocol stacks that exceed 8-bit MCU capability.
Typical applications include consumer electronics, industrial control nodes, USB peripherals, sensor hubs, low-cost graphical user interfaces, and home appliances. The combination of small Flash, ample I/O and USB makes it well suited to HID-class devices, motor control boards, and audio/graphics front-ends that need 32-bit headroom without stepping up to Cortex-M class pricing.
When designing with this part, ensure the exposed pad is soldered to a sufficiently large copper pour for thermal relief and ground integrity. Decouple VDD/VUSB with 100 nF + 4.7 uF ceramics placed within 3 mm of the pins, and follow Microchip's PIC32MX Family Reference Manual for DMA and PPS configuration to avoid pin conflicts.

Ghi chú thiết kế
The 28-VQFN package has an exposed thermal pad that MUST be soldered to a ground pour of at least 16 mm^2 to meet the datasheet's thermal and electrical performance. Place 100 nF + 4.7 uF ceramic decoupling capacitors within 3 mm of VDD and VSS pins, and keep D+/D- traces matched within 2 mm and length-matched to the USB connector to avoid signal-integrity issues.
Use the on-chip Low-Voltage Detect (LVD) and Brown-Out Reset (BOR) to protect Flash integrity during supply dips. Configure BOR for a trip voltage near 2.5 V so that a sagging 3.3 V rail does not corrupt program memory. For USB applications, VUSB must be tied to VDD through a ferrite bead and decoupled with 100 nF + 4.7 uF per the PIC32MX Family Reference Manual.
Do not confuse PGEC1/PGED1 (RB0/RB1) with PGEC2/PGED2 when designing the ICSP header. On 28-pin devices only PGEC1/PGED1 are bonded; using alternate pairs will fail programming. Also note that some QFN pads default to analog inputs at reset; configure them as digital with the appropriate ANSx register before reading GPIO, otherwise the digital input buffer stays disabled.
When using the USB OTG module, place a 90.9 ohm +/-1% series resistor on each of D+ and D- as close to the MCU as possible, and ensure the differential pair is routed with 90 ohm impedance. Avoid splitting the ground plane under USB traces; keep a continuous ground return path beneath the differential pair to suppress common-mode noise.
