PIC32MX210F016BT-V/SS Overview
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a 32-bit CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals such as timers, communication interfaces, and analog blocks. The PIC32MX family belongs to the PIC microcontroller hierarchy from Microchip, sits within the broader 32-bit MCU segment, and is widely used in applications that demand more computational headroom than 8-bit or 16-bit parts while preserving low power consumption.
Key features of this part include USB 2.0 full-speed device support, two I2S/SPI modules for codec and serial communication, Peripheral Pin Select (PPS) for flexible routing, a Parallel Master Port (PMP) for graphics interfaces, and a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch sensing. The device operates from 2.5V to 3.6V and is rated for the -40C to +105C automotive temperature range.
Architecturally, the MIPS32 M4K core delivers 1.56 DMIPS/MHz efficiency with single-cycle hardware multiply and a hardware divider for fast integer math. The 16 KB Flash supports self-programming for field upgrades, and the 4 KB SRAM supports small RTOS workloads. The integrated USB 2.0 full-speed device, PMP, and CTMU blocks allow designers to replace external components, reducing BOM cost and PCB footprint.
Typical applications include automotive body and HVAC controls, USB-capable consumer peripherals, low-cost graphics displays driven through PMP, capacitive touch user interfaces using CTMU, and industrial sensor hubs. The AEC-Q100 qualification makes the V temperature grade especially suitable for in-cabin automotive ECUs.
When designing with this part, plan for a 3.3V LDO or switching supply that can source at least 50 mA, follow Microchip's USB PCB layout guidelines for the D+/D- traces, and use the PPS feature to remap peripherals onto spare pins if a design change is needed late in the project.

Typical Applications
PIC32MX210F016BT-V/SS is suitable for 7 applications: Automotive Body Control Module, USB HID / CDC Peripheral, Capacitive Touch User Interface, Small Graphics / Segment LCD Panel, Industrial Sensor Hub, Audio Codec Interface (I2S), Battery-Powered Data Logger.
Automotive Body Control Module
The PIC32MX210F016BT-V/SS fits automotive body control and HVAC ECUs because it is AEC-Q100 qualified and rated for the -40C to +105C V automotive grade. The 40 MHz MIPS32 M4K core runs small CAN/LIN gateways and capacitive touch interfaces through the integrated CTMU. Using the Parallel Master Port, designers can also drive segmented LCD panels for HVAC faceplates. Replacing a discrete 8-bit MCU with this PIC32 allows consolidating body and lighting logic into one IC while keeping code size small enough to fit within the 16 KB Flash budget.
Recommended
USB HID / CDC Peripheral
The PIC32MX210F016BT-V/SS integrates a USB 2.0 full-speed device controller with on-chip transceiver, making it well suited to low-cost USB keyboards, mice, custom HID controllers, and CDC virtual COM ports. Microchip's free USB device stack supports HID, CDC, MSD, and vendor classes. At 66 DMIPS the M4K core handles HID polling and HID-to-serial translation without external logic. The 4 KB SRAM accommodates typical HID descriptors and small command buffers, and the 3.3V rail matches USB signaling levels directly when D+/D- pull-up is correctly configured.
Recommended
Capacitive Touch User Interface
The integrated CTMU (Charge Time Measurement Unit) and mTouch library make the PIC32MX210F016BT-V/SS ideal for capacitive touch keypads, sliders, and proximity sensors. The CTMU charges a touch pad and a reference capacitor with a known current source and measures the time delta to detect finger touch; the M4K core processes the results and handles debouncing. With 4 KB of SRAM and a 16 KB Flash budget, designers can implement multi-element sliders and piezo haptics feedback. PPS allows the touch channels to be remapped to spare pins if mechanical layout changes mid-design.
Recommended
Small Graphics / Segment LCD Panel
Driving a small character LCD or segment display from a 28-pin part is challenging without a dedicated peripheral, but the Parallel Master Port (PMP) integrated in the PIC32MX210F016BT-V/SS provides an 8-bit parallel master interface to control an external LCD controller such as the SSD1963 or segment driver. The 66 DMIPS core can refresh display buffers and run a UI state machine concurrently, while PPS keeps the PMP pins flexible. This application makes sense for 320x240 graphics panels in test and measurement front panels that must fit the 28-SSOP automotive V package.
Recommended
Industrial Sensor Hub
Industrial sensor hubs require a low-power 32-bit MCU with flexible peripherals, and the PIC32MX210F016BT-V/SS delivers that. Using the two I2S/SPI modules, the MCU can interface with MEMS microphones, accelerometers, and temperature sensors while the PPS feature routes UART and I2C traffic to available pins. The sub-0.5 mA/MHz active current consumption keeps total board power low, and the AEC-Q100 V grade tolerates harsh factory environments. With 16 KB Flash and 4 KB SRAM, the device can run Microchip's free MPLAB Harmony Configurator generated code for MODBUS RTU slave or small sensor fusion tasks.
Recommended
Audio Codec Interface (I2S)
The two I2S/SPI modules inside the PIC32MX210F016BT-V/SS enable direct connection to audio codecs such as the Microchip MCP4921 DAC family and external ADC codecs. Combined with the PMP and PPS, designers can build small audio front-ends for intercom panels and automotive infotainment accessories. The 16 KB Flash holds a basic PCM playback firmware, and 4 KB SRAM buffers stereo audio frames comfortably at 48 kHz. The AEC-Q100 V grade and -40C to +105C temperature window suit in-vehicle headrest intercoms and door-module chimes.
Recommended
Battery-Powered Data Logger
When paired with a small SPI FRAM and a real-time clock, the PIC32MX210F016BT-V/SS becomes a battery-friendly automotive data logger that records temperature, voltage, and event timestamps. The MIPS32 M4K core's less than 0.5 mA/MHz active consumption extends battery life, and the RTCC module keeps time while the core is in sleep. The AEC-Q100 V grade allows mounting in cabin or under-hood locations within the rated envelope. The 16 KB Flash and 4 KB SRAM are adequate for a circular event buffer plus Microchip's RTCC and MDDFS file-system library.

Key Differentiators
- AEC-Q100 automotive V grade qualification with V temperature suffix (vs PIC32MX210F016BT-I/SS)
- 16 KB Flash and 4 KB SRAM tuned for compact USB stacks (vs PIC32MX130F256B-I/SS)
- Native Parallel Master Port for small graphics (vs PIC32MX110F016BT-V/SS)
Design Notes
Place a 100 nF ceramic decoupling capacitor as close as possible to each VDD/VSS pair (pins 7/8 and 19/20) and add a bulk 10 uF tantalum or ceramic capacitor near the IC. The internal 1.8V regulator draws up to 25 mA on USB bursts, so a low-ESR bulk cap is required. For USB operation, the on-chip transceiver requires a stable 3.3V rail within +/-3%; use a dedicated LDO rather than sharing with switching converter noise sources.
Route the USB D+ (pin 24) and D- (pin 25) as a 90 ohm differential pair with matching length to within 150 mil, and keep the pair away from switching converter edges. Add a 90 ohm common-mode choke near the connector to pass EMI pre-compliance. The crystal traces (OSC1/OSC2, pins 26/27) must be short, surrounded by a ground guard ring, and kept away from the D+/D- pair to avoid jitter.
Do not confuse the V automotive grade suffix (-40C to +105C, AEC-Q100) with the I industrial grade (-40C to +85C). Mixing them up in safety-relevant automotive designs will fail qualification. Always configure the unused I/O pins as digital outputs (not floating inputs) to reduce current consumption and improve EMI. MCLR (pin 28) must have a 10 kohm pull-up to VDD - omitting it causes intermittent resets on noisy automotive supplies.
The 28-SSOP package has a theta_JA around 80 C/W on a standard 4-layer JEDEC test board. Estimated: at 40 MHz with full peripheral activity, the MCU consumes roughly 20 mA, so junction temperature rise is below 1.6 C above ambient. No heatsink is needed in sealed enclosures up to 70 C ambient, but the V grade limit of 105 C junction should be respected when the device is mounted near heat-generating components.
Compliance Information
AEC-Q100 qualified per Microchip product page for the V temperature grade. RoHS compliant per distributor listings.
