PIC32MX110F016DT-V/PT - 40MHz 32-bit MCU, 16KB Flash, AEC-Q100 | Microchip
MPN: PIC32MX110F016DT-V/PT ✓ Hoạt độngPIC32MX110F016DT-V/PT Tóm tắt
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a 32-bit processor core, program and data memory, and a rich set of peripherals (timers, communication interfaces, ADC/DAC, GPIO) into one package. Within the broader semiconductor taxonomy, an MCU belongs to the category of microcontrollers -> embedded processors -> integrated circuits. The PIC32MX family uses the MIPS32 M4K core, which sits in the same RISC lineage as other 32-bit MCU cores like ARM Cortex-M and competes in cost-sensitive embedded segments where deterministic performance and rich peripheral integration are required.
Key features of the PIC32MX110F016DT-V/PT include Peripheral Pin Select (PPS) for flexible signal assignment, a Parallel Master Port (PMP) for graphics interfaces, two I2S/SPI modules for codec and serial audio communication, a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch buttons and sliders, five 16-bit general-purpose timers, and an operating voltage range of 2.3V to 3.6V. The part supports up to 21 I/O ports and integrates USB, I2C, UART, SPI, and PMP peripherals. The 5V tolerant I/O and AEC-Q100 Grade 3 qualification enable deployment in automotive body and infotainment subsystems.
The architecture is built around the MIPS32 M4K Harvard-style core with separate instruction and data paths, single-cycle hardware multiply, and a multi-channel DMA controller for offloading data movement. The 40 MHz operation delivers approximately 50 DMIPS of computational throughput while consuming less than 0.5 mA/MHz, balanced for always-on and battery-tolerant designs. Five 16-bit timers can be paired to generate 32-bit timing events, and the CTMU simplifies touch-button and capacitive slider implementation without external analog front-ends.
Typical applications include automotive body electronics and HVAC controls, low-cost graphics HMI with PMP-driven TFT panels, USB audio peripherals and consumer audio codecs, capacitive touch user interfaces (mTouch), and industrial control nodes requiring AEC-Q100 qualification. The wide peripheral mix makes it well-suited for bridging legacy MCU designs into more capable 32-bit platforms.
When designing with this part, ensure your linker script reserves both the 16 KB Flash and 4 KB SRAM regions; the PIC32MX1xx family is offered in multiple memory density variants and choosing the wrong density at firmware-build time can silently truncate the image. The PPS feature must be configured before peripheral use, and the CTMU requires calibration of the internal current source for stable touch readings.

Ứng dụng tiêu biểu
PIC32MX110F016DT-V/PT phù hợp cho 6 Áp dụngs: Automotive Body Electronics, Low-Cost Graphics HMI with PMP, USB Audio Peripherals, Capacitive Touch User Interface (mTouch), Industrial Control Nodes, Battery-Connected Always-On Modules.
Automotive Body Electronics
The PIC32MX110F016DT-V/PT is purpose-built for AEC-Q100 automotive body modules where its -40C to +105C operating range and 5V-tolerant I/O simplify interfacing with 12V battery transients and legacy 5V sensors. The MIPS32 M4K core at 40 MHz delivers approximately 50 DMIPS of throughput, sufficient to run CAN-friendly software stacks or LIN master firmware while Peripheral Pin Select (PPS) lets the designer remap UART, I2C, and PWM to any spare GPIO to ease PCB routing. The 16 KB Flash accommodates typical body-control state machines and the 4 KB SRAM is large enough for the small RTOS tasks common in door, seat, and HVAC controllers. Place a 100 nF decoupling cap within 5 mm of every VDD pin and follow the automotive-grade layout guideline in the PIC32MX family datasheet section on EMI/ESD.

Low-Cost Graphics HMI with PMP
The integrated Parallel Master Port (PMP) on the PIC32MX110F016DT-V/PT drives small parallel TFT or STN panels up to 8-bit data width, enabling cost-optimized graphical human-machine interfaces without an external graphics controller. The 40 MHz MIPS core is sufficient to refresh a 320x240 QVGA panel at 30 fps while leaving cycles for touch and communications, and the CTMU provides on-chip capacitive touch sensing for buttons and sliders that share the same PCB. PPS allows reassigning the PMP data bus so that the designer is not constrained to a fixed pinout, which simplifies two-layer board routing. The AEC-Q100 grade means the same board can ship in both consumer and automotive variants by swapping the temperature grade suffix.

USB Audio Peripherals
The PIC32MX110F016DT-V/PT integrates a USB 2.0 full-speed device controller plus two I2S/SPI modules, allowing a single chip to implement a USB audio class device such as a headset adapter, USB DAC, or USB microphone. The MIPS32 M4K core runs the USB stack and audio sample-rate conversion at 40 MHz with margin, while the 4 KB SRAM holds USB endpoint buffers and a small audio ring buffer. CTMU handles headset-button press detection on the same MCU. Designers should reference the Microchip USB Audio device library and add 24 MHz crystal accuracy within +/-50 ppm to meet USB timing requirements; place the USB DP/DM trace as a 90 ohm differential pair as recommended in the PIC32MX family datasheet.
Được đề xuất
Capacitive Touch User Interface (mTouch)
The on-chip Charge Time Measurement Unit (CTMU) of the PIC32MX110F016DT-V/PT measures capacitance changes with sub-pC resolution, enabling robust mTouch capacitive buttons, sliders, and proximity sensors without an external analog front-end. PPS lets the designer route touch electrodes to almost any spare GPIO, simplifying PCB layout and allowing touch electrodes to live on the same flex as the display. The AEC-Q100 qualification supports automotive touch panels such as steering-wheel switches or overhead console controls. Microchip recommends calibrating the CTMU current source per board to compensate for parasitic capacitance, and the 16 KB Flash provides ample room for the mTouch library plus application firmware.

Industrial Control Nodes
The PIC32MX110F016DT-V/PT is well-suited for industrial sensor nodes, motor-control edge modules, and protocol converters where its -40C to +105C temperature range, 21 GPIO, and rich peripheral mix (UART, SPI, I2C, PMP) replace multiple 8/16-bit MCUs. The 40 MHz core runs MODBUS RTU or proprietary field-bus stacks while PPS reassigns peripheral functions to clean up PCB routing. AEC-Q100 qualification gives the design headroom for harsh industrial environments subject to vibration and temperature swings. For multi-axis motion or higher sampling rates, consider PIC32MX210F016DT-V/PT which doubles Flash and SRAM in the same footprint.

Battery-Connected Always-On Modules
The PIC32MX110F016DT-V/PT draws less than 0.5 mA/MHz in run mode, supporting always-on automotive and IoT modules connected directly to a 12V battery through a low-Iq regulator. Its idle and sleep modes with rapid wake-up via the CTMU or peripheral interrupts let the MCU spend most of its life in microamp-level sleep, only waking for sensor polling or communication events. PPS and a rich peripheral mix allow the same MCU to run a small LoRa or sub-GHz radio link alongside sensor sampling. Designers should use the MCP1700 or similar 1.6 uA quiescent LDO for the rail and follow Microchip app note guidelines for sleep-mode retention.

Ghi chú thiết kế
Estimated: at 40 MHz run mode, the PIC32MX110F016DT-V/PT consumes less than 20 mA core current (0.5 mA/MHz x 40 MHz) plus I/O drive. A 3.3V rail from a low-dropout regulator such as MCP1700 (250 mA) provides ample headroom. Place a 100 nF ceramic decoupling capacitor within 5 mm of every VDD/VSS pair to suppress switching transients, and add a bulk 10 uF tantalum or ceramic near the package to support peak load steps during USB enumeration.
Route the USB DP/DM pair as a 90 ohm differential with continuous ground reference and length matching within 2 mm to comply with USB 2.0 full-speed signaling. Keep the 24 MHz crystal traces short and surrounded by a ground guard ring; the secondary 32.768 kHz oscillator pins should likewise be guarded. Place the MCLR reset pull-up within 5 mm of the pin and add a 100 nF cap to ground if longer trace length is unavoidable. The 44-TQFP 0.8 mm pitch pads are reflow-compatible with standard lead-free profiles (peak 245C, 60 s above 217C).
Configure Peripheral Pin Select (PPS) before using any remappable peripheral function; out-of-reset GPIOs are high-impedance and will not drive peripherals until PPS registers are unlocked and written. Always specify the linker script for exactly 16 KB Flash and 4 KB SRAM; PIC32MX1xx variants with larger memory will compile but the boot code will not relocate vectors correctly. Do not leave MCLR floating in noisy automotive environments - add a 10 kohm pull-up plus a 100 nF cap to ground for ESD immunity. Finally, calibrate the CTMU current source against a known capacitance on each board because absolute capacitance varies with PCB layout and overlay material.
The PMP parallel data bus (PMD0-PMD15) on the PIC32MX110F016DT-V/PT can drive small TFT panels directly but signal integrity depends on short traces (<50 mm) and matched ground return paths. If the LCD connector is far from the MCU, add 33 ohm damping resistors in series with the data lines to reduce ringing. For I2S audio, keep I2S clock and data traces length-matched within 25 mm and route away from switching power and USB data pairs to avoid audio-band noise coupling into the DAC reference.
