PIC32MX210F016BT-V/ML - 40MHz 32-bit MCU 16KB Flash | Microchip
MPN： PIC32MX210F016BT-V/ML ✓ 啟用中PIC32MX210F016BT-V/ML 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (Flash for code, SRAM for data), and programmable peripherals (UART, SPI, I2C, timers, ADC). The PIC32MX family bridges 8-bit PIC legacy code with 32-bit MIPS performance, enabling migration of existing firmware while adding headroom for higher throughput. Within the broader taxonomy, this part sits as: microcontroller -> embedded processor -> integrated circuit -> semiconductor.
Key differentiators include the CTMU hardware block (used for capacitive buttons, sliders, and proximity sensing without an external IC), the PPS remapping engine (each peripheral function can be assigned to almost any I/O pin, simplifying PCB layout), and full-speed USB 2.0 device on-chip (saves an external PHY). The automotive-grade 'V' suffix (-40C to +105C) and AEC-Q100 qualification make the part suitable for in-cabin and chassis electronics that require automotive reliability. The 28-QFN exposed-pad package provides low thermal resistance for improved high-temperature operation versus SOIC alternatives.
Architecturally, the M4K core is a 5-stage pipeline MIPS32R2 implementation featuring single-cycle hardware multiply and a hardware divide unit. The 16 KB single-voltage Flash supports live updates via ICSP, and 4 KB SRAM is sufficient for TCP/IP stacks, USB device class drivers, or graphics framebuffers when paired with PMP-controlled displays.
Typical applications include automotive body modules (HVAC controls, lighting controllers, seat modules), industrial HMI with capacitive touch, consumer appliances with USB device connectivity, low-cost graphics display controllers via PMP, and USB-based firmware update dongles. The wide AEC-Q100 grade window also suits fan-driven remote sensor nodes.
When designing with this part, allocate the VDD and AVDD pins separately with local 0.1 uF + 1 uF decoupling, place a 12 kohm pull-up on D+ for USB device mode, and ensure the exposed pad on the QFN is thermally tied to the ground plane to meet the 105 C automotive junction limit.

典型應用
PIC32MX210F016BT-V/ML 適用於 6 應用s: Automotive Body Control Module, Capacitive Touch HMI Panel, USB Device Dongle / CDC Virtual COM Port, Low-Cost Graphics Display Controller, I2S Audio Codec Interface, IoT Sensor Hub with USB Logging.
Automotive Body Control Module
The PIC32MX210F016BT-V/ML fits automotive body modules such as HVAC panels, seat controllers, and lighting drivers where AEC-Q100 grade 'V' (-40C to +105C) qualification is required. Its 40 MHz MIPS32 M4K core delivers 66 DMIPS, sufficient for CAN-capable body firmware and capacitive touch button scanning via the on-chip CTMU. The integrated USB 2.0 FS device supports service-tool diagnostic interfaces, while the 4 KB SRAM and 16 KB Flash accommodate small RTOS-based stacks. The 28-QFN exposed pad provides low thermal resistance for under-dash mounting where ambient temperatures reach 85 C.
推薦
Capacitive Touch HMI Panel
The PIC32MX210F016BT-V/ML excels in capacitive touch HMI panels because of its CTMU (Charge Time Measurement Unit) hardware block, which scans mTouch capacitive buttons and sliders without an external touch IC. The 40 MHz core resolves touch events within the 10 ms refresh typical for industrial keypads, while the PPS function remaps I/O so sensor traces do not cross analog routing. 16 KB Flash stores the touch algorithm and slider gestures; 4 KB SRAM holds scan buffers. The AEC-Q100 grade makes the part equally viable in white-goods and industrial control panels.
推薦
USB Device Dongle / CDC Virtual COM Port
The PIC32MX210F016BT-V/ML is well suited for USB device dongles, including CDC virtual COM ports, HID peripherals, and DFU bootloaders, thanks to the integrated USB 2.0 full-speed device controller and on-chip pull-up driver. The MIPS32 M4K core at 40 MHz handles USB class drivers comfortably, and the 16 KB Flash stores Microchip MLA USB stack plus application code. Industrial-grade USB-to-serial bridges using this MCU appear in test fixtures, factory programming tools, and configuration dongles where 5 V tolerant GPIO is not required.
推薦
Low-Cost Graphics Display Controller
The PIC32MX210F016BT-V/ML drives small parallel TFT or character LCD panels via its Parallel Master Port (PMP), reducing BOM cost versus SPI-only MCUs that need additional controller ICs. PMP throughput at 40 MHz easily refreshes 320x240 QVLC-lockscreens and static menus, while 4 KB SRAM is enough for full-frame buffers up to 64 KB through page-flip schemes. The CTMU and I2S peripherals add audio cue support in the same MCU, replacing separate audio ICs in cost-sensitive appliance or equipment interfaces.
推薦
I2S Audio Codec Interface
The PIC32MX210F016BT-V/ML supports two I2S modules for interfacing with audio codecs in intercoms, door stations, and consumer audio docks. Its 40 MHz MIPS32 core runs software MP3/WAV decode for short voice prompts while streaming I2S to an external DAC, eliminating a dedicated audio processor. The PPS engine remaps I2S clock/data to any GPIO, simplifying PCB routing. Combined with the AEC-Q100 grade, this makes the part attractive for automotive premium-audio head-unit auxiliary inputs and in-cabin entertainment modules.
推薦
IoT Sensor Hub with USB Logging
The PIC32MX210F016BT-V/ML fits industrial IoT sensor hubs that log to USB sticks thanks to USB device/host support and core MIPS32 processing at 66 DMIPS. It reads I2C sensors for temperature, humidity, or pressure while running a USB mass-storage stack to write CSV files directly to USB media. The CTMU block also handles user-facing capacitive buttons. Industrial-grade or automotive-grade temperature range makes this MCU appropriate for factory-floor edge nodes and battery-monitoring modules.

設計說明
Decouple both VDD/AVDD pairs with a 0.1 uF ceramic in parallel with a 4.7 uF bulk capacitor placed within 5 mm of the pins. The PIC32MX210F016BT-V/ML core draws up to 20 mA active and <0.5 mA/MHz, so a switching DC-DC or low-dropout regulator with 100 mA headroom is appropriate. Keep the AVDD trace isolated from switching nodes to preserve ADC and CTMU accuracy. Estimate: at 40 MHz full activity, IDD peaks near 20 mA; idle standby is typically 30-50 uA.
The 28-QFN exposed pad must be soldered to a continuous ground plane with at least 8 thermal vias (0.3 mm in spec drill, 1 mm pitch) for heat dissipation. Without proper thermal vias, junction temperature can rise 30-40 C above ambient at 40 MHz full activity, threatening AEC-Q100 compliance at +105 C ambient. Mirror reference Microchip AN1267 'PIC32MX Thermal Management' for land-pattern recommendations.
Place the 12 MHz crystal (or 8 MHz for PLL to 40 MHz) within 5 mm of OSC1/OSC2 with guard traces around the oscillator pins. The USB D+/D- pair must be routed as a 90-ohm matched pair, 8-12 mil trace width, no stubs, and no place other signals between them. Microchip AN588 'PCB Layout for PIC32MX USB' recommends common-mode choke footprints even on full-speed designs.
Common pitfalls include forgetting the MCLR pull-up (10 kohm to VDD) which leaves the MCU in reset, omitting the 12 kohm pull-up on USB D+ which prevents enumeration, and configuring PPS without unlocking the IOLOCK sequence, which silently breaks peripheral routing.
