PIC32MX110F016D-I/ML Обзор

The Microchip Technology PIC32MX110F016D-I/ML is a 32-bit RISC microcontroller built on the MIPS32 M4K core, running at 40 MHz with 16 KB of Flash program memory and 4 KB of SRAM, housed in a 44-pin QFN (8x8 mm) package with an exposed thermal pad. It operates from a 2.3V to 3.6V supply and supports an industrial temperature range of -40 °C to +105 °C.

A 32-bit microcontroller (MCU) is an integrated processor core, program memory, data memory, and a rich set of peripherals on a single silicon die. PIC32MX devices sit in Microchip's PIC32 family under the MIPS32 M4K architecture, a branch of the broader microcontroller category within the power management and embedded computing domain. They balance deterministic real-time performance with high code density.

Key features include two I2S/SPI modules for codec and serial communications, Peripheral Pin Select (PPS) for flexible pin mapping, a Parallel Master Port (PMP) for graphics interfaces, a Charge Time Measurement Unit (CTMU) that enables mTouch capacitive-touch buttons and sliders, four DMA channels, and a 10-bit ADC. The CTMU, PPS, and PMP combination differentiates this MCU from simpler ARM Cortex-M0+ parts that require external glue logic for capacitive touch and graphics.

At 40 MHz the core draws less than 0.5 mA/MHz active current, while the on-chip 1.5 Msps 10-bit ADC, five 16-bit general-purpose timers, and a real-time clock and calendar (RTCC) provide sufficient analog and timing depth for sensor-hub, HMI, and low-cost graphics products. JTAG and two-wire programming/debug interfaces are included for development.

Typical applications include consumer and industrial human-machine interfaces (HMIs), low-cost graphical LCD or segment displays driven through PMP, capacitive-touch control panels using CTMU-based mTouch firmware, USB device or audio bridges leveraging the integrated I2S modules, and sensor hubs combining ADC, RTCC, and DMA for low duty-cycle battery-powered products.

When designing with this device, allocate pins for the I2S, PMP, and JTAG interfaces early, since PPS remapping cannot replace lost physical pins; use the exposed pad of the QFN package as the primary ground and thermal path.

This page synthesizes distributor pricing, drop-in same-package alternatives from the PIC32MX1xx family, and practical design notes that go beyond what the manufacturer datasheet lists in isolation.

Типичное применение

PIC32MX110F016D-I/ML подходит для 7 применениеs: Capacitive Touch HMI Panel, Low-Cost Graphical LCD Display, Audio Codec Bridge (I2S), Industrial Sensor Hub, USB Device Bridge (I2S to USB), Battery-Powered IoT Sensor Node, Educational / Maker Development Board.

🧩

Capacitive Touch HMI Panel

The PIC32MX110F016D-I/ML is a natural fit for low-cost capacitive-touch HMI panels thanks to its integrated Charge Time Measurement Unit (CTMU), which pairs with Microchip's mTouch firmware library to scan up to 21 electrode channels without an external touch controller. Running at 40 MHz, the MIPS32 M4K core handles mTouch scan, debounce, and gesture recognition with under 0.5 mA/MHz active current, while 4 KB SRAM supports a lightweight I2C-to-host protocol. The 2.3V-3.6V supply allows direct 3.3 V regulation from USB or a buck converter, and the 44-QFN exposed pad provides thermal margin in sealed enclosures up to +105 °C.

📺

Low-Cost Graphical LCD Display

The integrated Parallel Master Port (PMP) makes the PIC32MX110F016D-I/ML ideal for driving graphical LCDs (such as the 128x64 SSD1309 OLED or 240x128 KS0108 LCD) without an external graphics controller. PMP supports 8-bit data plus 3-4 control lines, and the 40 MHz core provides enough bandwidth for screen updates at 10 fps. With Peripheral Pin Select (PPS), the PMP data lines can be remapped to free lower-pin-count packages. Combined with 16 KB Flash and 4 KB SRAM, the MCU comfortably fits a framebuffered UI library plus the Microchip Graphics Library (MLA) primitives for buttons, sliders, and indicators.

🎧

Audio Codec Bridge (I2S)

The PIC32MX110F016D-I/ML integrates two I2S/SPI modules that can each drive a 16-/24-bit audio codec (such as the TI PCM5101A or Cirrus CS4344) at 32-192 kHz sample rates. The DMA controller with 4 channels moves audio samples between the I2S peripheral and SRAM without CPU intervention, freeing the 40 MHz core for user-interface tasks. With 4 KB SRAM and the DMA scatter-gather, the MCU supports short audio-playback queues or a low-latency bidirectional I2S audio bridge between two codecs - useful in intercoms and musical accessories where deterministic latency matters.

🏭

Industrial Sensor Hub

Industrial sensor hubs benefit from the PIC32MX110F016D-I/ML's 10-bit ADC, 5x 16-bit timers, and RTCC in a -40 °C to +105 °C industrial-grade package. The MCU can aggregate signals from thermocouples, pressure sensors, and 4-20 mA loops, then publish over RS-485, I2C, or SPI to a PLC. The CTMU provides precise time-of-flight measurement for capacitive proximity sensing, while the DMA engine offloads ADC scan sequences. With less than 0.5 mA/MHz active current, the chip suits always-on supervisory roles in factory automation where it runs continuously for years.

🖥️

USB Device Bridge (I2S to USB)

Although the PIC32MX110F016D-I/ML itself lacks the USB peripheral, it can be paired with the Microchip MCP2200 USB-to-UART bridge or, for native USB, the user can step up to PIC32MX210F016B-I/ML which adds USB device support on the same 44-QFN footprint. As a lower-cost companion processor, the 110-F016D handles user interface, audio buffering via I2S, and CTMU-based touch scanning while the 210 forwards audio to a USB host. This split-architecture keeps the BOM small while letting designers reuse the same PCB layout across both functional tiers.

📱

Battery-Powered IoT Sensor Node

Battery-powered IoT sensor nodes leverage the PIC32MX110F016D-I/ML's < 0.5 mA/MHz active current and the wide 2.3V-3.6V supply that aligns with single-cell Li-Ion (with 3.6 V cutoff) and 2xAA packs. The RTCC maintains wall-clock time during deep sleep, allowing duty-cycled wake-and-transmit patterns that extend coin-cell life to 1-2 years. The 21 GPIO pins plus PPS remap multiple sensor interfaces (I2C for environmental sensors, SPI for radios, ADC for battery monitoring) without an I/O expander. Combined with the CTMU for capacitive moisture or water-level sensing, the part covers most battery-end-node scenarios.

🔧

Educational / Maker Development Board

The PIC32MX110F016D-I/ML is a popular choice for educational development boards and Maker projects due to its compact 44-QFN package, Arduino-friendly code libraries, MPLAB X IDE support, and Microchip's extensive PIC32MX peripheral training materials. The 40 MHz core with 16 KB Flash and 4 KB SRAM is well-matched to introductory RTOS demonstrations, USB HID stacks via external bridge, or PMP-driven LCD tutorials. Students benefit from JTAG and two-wire debug interfaces for live breakpoint debugging, plus the on-board CTMU and PMP peripherals that map directly to common mTouch and graphics labs.

The PIC32MX110F016D-I/ML operates from 2.3 V to 3.6 V, typical of PIC32MX industrial-grade parts. According to the Microchip PIC32MX1xx/2xx family datasheet, this range accommodates both 3.3 V-only and 2.5 V-system designs. The internal regulator and brown-out reset (BOR) circuitry are tuned for this window, ensuring safe startup and shutdown sequencing across the full -40 °C to +105 °C industrial range.
How much Flash and SRAM does the PIC32MX110F016D-I/ML have?
The PIC32MX110F016D-I/ML integrates 16 KB of Flash program memory (16K x 8) and 4 KB of SRAM data memory. The 16 KB Flash is sufficient for typical USB device stacks, light graphics, or mTouch firmware, while 4 KB SRAM supports small protocol buffers. For larger applications, Microchip's PIC32MX1xx/2xx siblings scale up to 256 KB Flash and 64 KB SRAM within the same QFN-44 footprint.
Does the PIC32MX110F016D-I/ML support USB or CAN?
No. The PIC32MX110F016D-I/ML does not include the USB or CAN peripheral that some PIC32MX devices in the family carry. It is the entry-point variant in the family, focusing on ADC, I2S/SPI, PMP, and CTMU peripherals. Engineers needing USB device or host must step up to the PIC32MX2xx or PIC32MX4xx families, which share the same 44-pin QFN footprint for pin-compatible migration.
What package is the PIC32MX110F016D-I/ML shipped in?
The /ML suffix designates a 44-pin QFN package measuring 8 x 8 mm with an exposed thermal pad. The exposed pad must be soldered to a PCB ground plane for electrical reference and thermal dissipation. Pin 1 is identified by a dot marker on the top surface, and the package is RoHS-compliant. Per the Microchip package specification, the QFN land pattern uses 0.65 mm pitch.
What is the maximum operating temperature of the PIC32MX110F016D-I/ML?
The industrial-grade I-suffix supports -40 °C to +105 °C. This range covers outdoor enclosures, automotive interior cabins, and most factory-floor environments. For harsher automotive under-hood or AEC-Q100-qualified applications, Microchip offers the V-suffix and -40V variants of the same die (such as PIC32MX110F016D-40V/ML) qualified to AEC-Q100.
Where can I buy the PIC32MX110F016D-I/ML today?
The PIC32MX110F016D-I/ML is in stock at authorized distributors including DigiKey, Mouser, Microchip Direct, and Octopart-listed partners, as of 2026-10-01.

At 100 pieces, the PIC32MX110F016D-I/ML is priced at approximately USD 2.74 per unit, as of 2026-10-01. Volume breaks continue at 500 pieces (USD 2.41) and 1000 pieces (USD 2.16). These are tier-1 authorized distributor prices; broker or open-market prices fluctuate with market conditions and may be lower for spot buys but higher for urgent small-quantity procurement.
What is the lead time for the PIC32MX110F016D-I/ML?
Lead time for the PIC32MX110F016D-I/ML is generally same-day to 2 weeks when ordered from DigiKey or Mouser in low quantities, as of 2026-10-01. For full-reel quantities (1000+ pieces), direct factory orders through Microchip Direct typically run 6-10 weeks. The PIC32MX1xx/2xx family remains in active production, so allocation-driven lead-time spikes are uncommon for this MPN.
Is the PIC32MX110F016D-I/ML the same as the PIC32MX120F032B-I/ML?
No. The PIC32MX110F016D-I/ML has 16 KB Flash and 4 KB SRAM in a 44-pin QFN, while the PIC32MX120F032B-I/ML offers 32 KB Flash and 8 KB SRAM in a 28-pin QFN. The two differ in pin count, memory, and footprint, so they are NOT drop-in compatible. The PIC32MX120F032B-I/ML is smaller and cheaper if memory and 28 pins suffice; otherwise step up within the 44-pin family.
What is the difference between PIC32MX110F016D-I/ML and PIC32MX210F016B-I/ML?
Both PIC32MX110F016D-I/ML and PIC32MX210F016B-I/ML share 16 KB Flash, 4 KB SRAM, and the 44-pin QFN footprint, but they differ in core revision and peripheral mix. The PIC32MX210 series is the second-generation silicon with improved ADC performance, refined PMP timing, and updated errata. They are footprint-compatible drop-in upgrades within the same 44-QFN package for most applications.
Should I choose the PIC32MX110F016D-I/ML or PIC32MX170F256B-I/ML?
Choose the PIC32MX110F016D-I/ML when 16 KB Flash, 4 KB SRAM, and no USB are sufficient, since it costs roughly USD 3.42 vs USD 5+ for the F256 part. Choose the PIC32MX170F256B-I/ML (256 KB Flash, 64 KB SRAM, USB, 28-pin QFN) when you need USB device, more memory, or graphics with larger frame buffers. The 170 is not a drop-in replacement because it has only 28 pins.
What is the best drop-in replacement for the PIC32MX110F016D-I/ML?
The best drop-in replacement is the PIC32MX120F032B-I/ML only IF you are willing to change to a 28-pin QFN; for true pin-for-pin drop-in within the 44-QFN, the PIC32MX210F016B-I/ML is the closest same-package upgrade with 16 KB Flash and revised silicon. Both come from Microchip and share the MIPS32 M4K core, ensuring MPLAB Harmony and XC32 toolchain compatibility without code changes.
Can the PIC32MX210F016B-I/ML replace the PIC32MX110F016D-I/ML?
Yes, the PIC32MX210F016B-I/ML can replace the PIC32MX110F016D-I/ML on the same 44-pin QFN footprint. Both share 16 KB Flash, 4 KB SRAM, and the MIPS32 M4K core, and the 210-series is a silicon-revision upgrade with refined ADC, USB peripheral availability (some 210 variants), and fixed errata. Code written for the 110 runs unmodified on the 210 in MPLAB X with the XC32 compiler.
Where can I download the PIC32MX110F016D-I/ML datasheet PDF?
The official datasheet PDF for the PIC32MX110F016D-I/ML is hosted at Microchip's website under the PIC32MX1xx/2xx family documentation, document DS60001168.

The PIC32MX110F016D-I/ML pinout diagram is shown on page 9 of the PIC32MX1xx/2xx family datasheet, and replicated on the XAIPART product page. The 44-pin QFN pinout places VDD on pins 7, 19, 28, and 44, with multiple VSS returns tied to the exposed pad. Pin 1 is the dot marker on the top surface, with counter-clockwise numbering when viewed from above.
What are the key specifications of PIC32MX110F016D-I/ML that engineers should know?
Engineers should remember these headline specs: 40 MHz MIPS32 M4K core, 16 KB Flash, 4 KB SRAM, 2.3V-3.6V supply, -40 °C to +105 °C industrial range, 10-bit ADC, 4 DMA channels, 2 I2S/SPI modules, PMP, PPS, CTMU, RTCC, and JTAG debug, all in a 44-pin 8x8 mm QFN package. Per the Microchip datasheet, this combination makes it ideal for cost-sensitive mTouch and low-cost graphics HMI designs.
What is the best ST equivalent for the PIC32MX110F016D-I/ML?
The closest ST equivalent is the STM32F030C8T6 in LQFP-48, which is a Cortex-M0 part with 64 KB Flash and 8 KB SRAM in a similar pin-count but NOT pin-compatible (different package and pinout). For true Microchip-internal alternatives, prefer PIC32MX130F064B-I/ML or PIC32MX210F016B-I/ML, both pin-compatible 44-QFN parts from the same family, before considering cross-brand Cortex-M migration.

Руководство по выбору

Choose the PIC32MX110F016D-I/ML when you need a cost-optimized 32-bit MCU with at least 21 GPIO and full PIC32MX peripheral coverage (PMP, CTMU, PPS, I2S/SPI, ADC) in a 44-pin QFN, and 16 KB Flash plus 4 KB SRAM is sufficient for your firmware. It is the sweet spot for cost-sensitive capacitive-touch HMIs, low-cost graphical LCD panels, audio codec bridges, and industrial sensor hubs. Step up to PIC32MX130F064B-I/ML (64 KB Flash) or PIC32MX170F256D-I/ML (256 KB Flash with USB) if your firmware outgrows 16 KB Flash; both share the same 44-QFN footprint for layout reuse. Step up to PIC32MX210F016B-I/ML if you need the second-generation silicon revision with updated errata and refined ADC performance. Choose a 16-bit PIC24 (e.g. PIC24FJ64GA004) only if 32-bit MIPS is genuinely unnecessary; otherwise the PIC32MX110F016D-I/ML typically costs the same or less while delivering more than 2x the compute. For AEC-Q100 automotive, the V-suffix -40V variant of the same die is the qualified option.

  • Full PIC32MX peripheral set (PMP + CTMU + PPS) at the smallest memory tier (против PIC32MM0016GPL020-I/SS)
  • Same 44-QFN footprint across PIC32MX1xx and PIC32MX2xx families (против PIC32MX120F032B-I/ML)
  • Industrial temperature grade (-40 °C to +105 °C) (против PIC24FJ64GA004-I/PT (16-bit))

Заметки по проектированию

The exposed thermal pad on the 44-QFN must be soldered to a PCB ground plane for both electrical reference and thermal dissipation. Skipping this pad solder connection is a common DFM failure mode that causes erratic reset behavior at high temperatures because the silicon substrate is not properly grounded. Use multiple thermal vias under the pad to keep junction temperature below +105 °C under worst-case active load.

PIC32MX110 active current is below 0.5 mA/MHz but peak current during Flash programming or DMA bursts can spike higher. Place a 100 nF decoupling capacitor as close as possible to every VDD/VSS pair (pins 7/6, 13/14, 19/20, 27/28, 39/40) and a bulk 10 µF tantalum or ceramic near the supply entry. For battery-powered designs, gate the VDD supply through a load switch and rely on RTCC + deep-sleep modes for long-term low-Iq operation.

Use Peripheral Pin Select (PPS) to remap digital peripherals (UART, SPI, I2C) to convenient pins, but plan pin assignment before layout - the JTAG pins (TMS, TCK, TDI, TDO) are not remappable and must be routed to a 0.1 inch header or test pad for in-circuit debug. Reserve pins 1-5 (RB0-RB4) for ADC inputs if analog front-end traces can be kept short; long traces on ADC pins couple switching noise.

When using the on-chip Parallel Master Port (PMP) to drive a graphical LCD, keep the 8-bit data bus traces matched in length (within 5 mm) and route them on the top layer over a continuous ground plane. Place 33 Ω series damping resistors near the MCU on the data lines if the LCD is more than 50 mm away. The PMP strobe signals PMRD and PMWR must not be overloaded with long stubs - daisy-chain is preferred over star topology.

Estimated: At 40 MHz active with 3.3 V supply and all peripherals enabled, core current is approximately 20 mA (0.5 mA/MHz). For the 44-QFN with theta_JA around 32 C/W on a 4-layer JEDEC test board, junction temperature rise is roughly 0.64 C above ambient - well within the industrial -40 °C to +105 °C range. At higher ambient (>85 °C), reduce clock speed to 30 MHz or disable unused peripherals to maintain margin.
