It operates at up to 25 MHz and delivers 79 CoreMark performance, while consuming only a few microamps in deep sleep modes, making it ideal for USB-equipped battery-powered and energy-harvesting applications. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals. The 32-bit MCU class extends 8/16-bit devices with higher compute throughput, larger addressable memory, richer DSP support, and modern peripherals such as USB, CAN, and capacitive touch sensing. PIC32MM GPM sits within Microchip's PIC32 portfolio as the lowest-power, most cost-effective branch, hierarchically: 32-bit MCU -> ARM/MIPS architecture -> PIC32 family -> PIC32MM GPM sub-family. Key features include a USB 2.0 Full-Speed Device/Host/OTG controller, 4-channel DMA, Configurable Logic Cell (CLC), 12-bit ADC, 10-bit DAC, multiple PWM/SCCP/MCCP timers, RTCC, I2C, SPI, UART, and 21 general-purpose I/O pins. Hardware ECC on Flash and RAM provides enhanced reliability for safety-conscious designs, while a 4-wire programming/debug interface (PGDx/PGECx) enables MPLAB X IDE and ICD support. The device uses Microchip's proprietary microMIPS ISA option to balance code density and throughput, with the MIPS32 microAptiv core providing deterministic interrupt latency. Internal LDO and a flexible 2.0V-3.6V supply range support single-cell Li-ion or 3.3V regulated rails, with multiple low-power modes (Sleep, Deep Sleep, Deep Sleep with RTCC) achieving deep-sleep currents in the low microamp range. Typical applications include consumer USB HID devices such as mice and game controllers, IoT sensor nodes, low-power wearables, smart home peripherals, battery-powered medical monitors, and industrial HMI panels. The combination of USB, large memory, and ultra-low sleep current is uniquely suited to tethered or intermittently connected products. When designing with this device, place the 4x4 UQFN land pattern with proper thermal vias under the exposed pad, route the USB DP/DM pair as a 90-ohm differential with controlled impedance, and follow Microchip's MPLAB Harmony framework for peripheral drivers. Note the -E/M6 suffix denotes the -40C to +125C extended temperature grade and UQFN-28 package; -I/M6 (industrial -40C to +85C) is also available for less demanding environments.

PIC32MM0256GPM048-E/PT - 32-bit 25MHz 256KB Flash MCU | Microchip

The Microchip PIC32MM0256GPM048-E/PT is a 32-bit eXtreme Low Power (XLP) microcontroller from the PIC32MM GPM family, featuring a MIPS32 microAptiv core running at up to 25 MHz, 256 KB of ECC Flash, and 32 KB of SRAM in a 48-pin TQFP-EP (7x7 mm) package. It operates from a 2.0 V to 3.6 V supply, integrates a full-speed USB 2.0 device controller, and targets cost-sensitive low-power embedded designs with strict memory integrity requirements. A 32-bit microcontroller (MCU) is a single-chip processor that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals on one die. The 32-bit MIPS microAptiv core used here offers higher code density and arithmetic performance than 8/16-bit MCUs at similar clock rates, while ECC Flash protects against soft errors common in industrial and IoT deployments. As part of the broader PIC32 family, this MCU sits between 8-bit PIC MCUs and high-performance PIC32MX/MZ parts, targeting applications that need USB connectivity without the cost of larger devices. Key features include a 4-channel DMA controller, 21 timers, 3 analog comparators, a 12-bit 200 ksps ADC with up to 19 channels, 3 I2C, 3 SPI, and 5 UART/LIN ports, plus a Cryptographic Engine and Peripheral Pin Select (PPS) for flexible signal routing. The integrated USB 2.0 Full-Speed device with internal pull-up resistors eliminates external components, while the 79 CoreMark benchmark at 25 MHz demonstrates ample processing headroom for sensor fusion and protocol stacks. The device also provides multiple low-power modes including Sleep, Idle, and Deep Sleep with Real-Time Clock/Calendar (RTCC) retention, drawing under 5 µA in Deep Sleep. Architecture highlights include single-cycle 32-bit ALU instructions, hardware divide, a prefetch cache, and a Peripheral Trigger Generator for low-latency peripheral-to-peripheral signaling. PPS remaps most digital peripherals to multiple I/O pins, simplifying PCB layout when signal integrity or routing constraints conflict with peripheral pin assignments. Hardware ECC on Flash detects and corrects memory errors autonomously, supporting IEC 60730 Class B safety requirements in household appliances. Typical applications include USB Human Interface Devices (HID) like keyboards and mice, low-power sensor nodes with USB diagnostics, IoT edge controllers, fitness wearables, motor control for small appliances, and consumer USB peripherals. The combination of 256 KB Flash and USB makes the device especially attractive when firmware updates or data logging require both large code space and a standard PC interface. For designers, the principal trade-off is core speed: at 25 MHz/79 CoreMark this part targets low-power USB, not high-throughput DSP or graphics. Ensure Vcap pin has a proper 4.7 µF decoupling capacitor to stabilize the internal 1.8 V core voltage regulator, and route USB D+/D- as a 90-ohm differential pair for USB compliance.

PIC32MM0256GPM048T-I/PT - 32-bit 25MHz 256KB MCU 48-TQFP | Microchip

The Microchip Technology PIC32MM0256GPM048T-I/PT is a 32-bit MIPS32 microAptiv PIC microcontroller operating at up to 25 MHz, integrating 256 KB of Flash and 32 KB of SRAM into a 48-pin TQFP-EP (7x7 mm) package with an exposed thermal pad. It is part of the eXtreme low power PIC32MM GPM family and runs from a 2.0V to 3.6V supply. The part combines a fast deterministic core, a USB 2.0 Full-Speed device/host/OTG controller, and Error-Correcting Code (ECC) memory for robust industrial and consumer designs. A microcontroller (MCU) is a single-chip computer that combines a CPU, memory and programmable peripherals into a single IC; the PIC32MM family belongs to the broader 32-bit MCU taxonomy (32-bit MCU -> RISC microcontroller -> embedded controller -> semiconductor IC) and is purpose-built for low-power mixed-signal applications. The microAptiv core implements the MIPS32 instruction set with hardware multiply/divide and a Memory Management Unit-like configuration, giving it deterministic interrupt latency for real-time control. The on-chip 32 KB SRAM is ECC-protected against soft errors, while the 256 KB Flash supports live update and a configurable Prefetch module that lets the core execute from Flash with zero wait state on most accesses. Key differentiating features include: 4-channel hardware DMA, a 12-bit ADC with up to 24 channels and 200 ksps throughput, three 16-bit timers/captures/PWMs, up to nine CCP/SCCP modules, an integrated USB 2.0 FS transceiver that eliminates external PHY cost, and configurable peripherals that allow pin-mapping remap. The device supports multiple serial interfaces including UART, SPI (3-wire/4-wire/Quad-SPI optional), I2C and I2S, along with PMP/EPMP for parallel display or memory buses. Power-saving features include Deep Sleep, Sleep, Idle and Peripheral Module Disable modes that drive quiescent consumption into the microampere range. Typical applications include USB HID peripherals such as PC gaming mice/keyboards, low-cost IoT sensor nodes, cost-optimized consumer appliances, industrial data loggers, and small-color graphics HMI with parallel display. The USB OTG capability lets designers build dual-role devices (e.g., USB-C chargers, debug bridges) without adding a USB IC, while the 256 KB flash accommodates a full TCP/IP or USB stack plus application code. Design trade-off: although the PIC32MM GPM provides strong low-power behavior, designers migrating from PIC32MX should confirm that their existing firmware uses the Harmony configurator (PMSM, ICSP) projects. The exposed thermal pad (EP) must be soldered for thermal and electrical reference - failing to do so derates power performance and may cause latch-up under high-current loads.

Compared with a discrete 8-bit MCU plus external ADC, the PIC32MX110F016B integrates peripherals and 32-bit compute into a single SOIC-28 footprint, reducing PCB area and BOM count. Designers should note that the 28-SOIC package is 0.300" wide (not the narrow 0.150" version); use appropriate land pattern. Decoupling: place a 100 nF ceramic near each VDD/VSS pair, with a 10 µF bulk capacitor at the regulator output. For CTMU touch sensing, follow Microchip AN1250 PCB layout guidelines to minimize trace-to-trace capacitance that can degrade touch sensitivity. This page synthesizes drop-in alternatives in the same 28-SOIC footprint, current distributor stock and pricing, and practical design considerations not found in the manufacturer datasheet.

PIC32MX110F016B-I/SS

PIC32MX110F016B-I/SS - 40MHz 32-bit MCU 16KB Flash | Microchip

The Microchip PIC32MX110F016B-I/SS is a 32-bit MIPS32 M4K microcontroller delivering 40 MHz CPU performance with 16 KB Flash and 4 KB SRAM in a 28-pin SSOP package. It is part of the PIC32MX1XX/2XX family of general-purpose microcontrollers and is targeted at cost-sensitive embedded designs that need more performance than 8/16-bit MCUs can offer while retaining a simple peripheral set. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripherals such as timers, ADC, and communication interfaces on one die. The PIC32MX1XX/2XX family belongs to the broader category of 32-bit microcontrollers -> RISC microcontrollers -> MIPS32-based MCUs -> embedded processors -> semiconductors. It is designed as an entry-level upgrade path for engineers migrating from PIC16/PIC24 devices who need higher throughput for USB, graphics, or audio front-end tasks. Key features include a 10-bit ADC with up to 12 analog input channels, four hardware DMA channels, a Charge Time Measurement Unit (CTMU) for touch and capacitive sensing, two UART, two SPI, and two I2C peripherals, plus a Parallel Master Port (PMP) for graphics or external memory expansion. The 21 general-purpose I/O pins support Peripheral Pin Select (PPS), which allows digital peripheral signals to be remapped to a wide range of physical pins, simplifying PCB layout. The device operates from 2.3 V to 3.6 V with industrial -40C to +85C temperature range. Internally the PIC32MX110F016B uses the MIPS32 M4K core with single-cycle hardware multiply/divide, a 5-stage pipeline, and a separate PLL for the system clock. Five 16-bit timers/counters and a configurable watchdog with on-chip low-power RC oscillator provide robust task scheduling. The part supports ICSP (In-Circuit Serial Programming) and JTAG debugging through the MPLAB X IDE with the free XC32 compiler, enabling rapid firmware development. Typical applications include USB HID devices, low-cost audio playback front-ends, capacitive touch user interfaces, sensor hubs, and small graphic LCD controllers. The combination of CTMU, DMA, and PMP makes it a fit for human-machine interface (HMI) panels and consumer appliances. When designing with this MCU, allocate the 16 KB Flash budget carefully - the bootloader plus USB stack plus application code leaves only a few KB for user logic. Use the CTMU and DMA offload the CPU from touch scanning to keep MIPS available for application work. Pin 1 dot marker should be observed carefully for SSOP-28 land pattern.

PIC32MX110F016B-V/SP - 40MHz 32-bit MCU, 16KB Flash | Microchip
PIC32MX110F016B-V/SP

PIC32MX110F016B-V/SP - 40MHz 32-bit MCU, 16KB Flash | Microchip

The Microchip Technology PIC32MX110F016B-V/SP is a 32-bit RISC microcontroller built on the MIPS32 M4K core, running up to 40 MHz with less than 0.5 mA/MHz current consumption, housed in a 28-pin SPDIP package. The device integrates 16 KB of Flash program memory and 4 KB of SRAM, 21 general-purpose I/O pins, and operates from a 2.3 V to 3.6 V supply across a -40 °C to +105 °C industrial temperature range. A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich peripheral set on one die. Within the broader taxonomy, PIC32MX devices sit between 8-bit PIC16/PIC18 MCUs and higher-end Cortex-M parts, forming Microchip's mid-range 32-bit MCU family targeting audio/graphics, USB, and advanced analog applications. The PIC32MX110F016B-V/SP is positioned as the entry-level Flash member of the PIC32MX1XX/2XX 28/36/44-pin family, optimized for cost-sensitive designs that still need DSP-class throughput and USB connectivity. Key differentiating features include Peripheral Pin Select (PPS) for flexible function-to-pin remapping, a Parallel Master Port (PMP) for graphics interfaces, two I2S/SPI modules for codec/serial audio, a 10-bit ADC with multiple analog channels, and a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch sensing. Direct Memory Access (DMA) offloads CPU data movement, while five 16-bit timers (and up to two 32-bit timers) give flexible event timing. AEC-Q100 qualification supports automotive deployment, especially in the -V (industrial-grade) operating range. Architecturally, the MIPS32 M4K core executes most instructions in a single cycle with hardware multiply/divide and a 5-stage pipeline. The 16 KB Flash and 4 KB SRAM are sized for compact control loops, USB device stacks (CDC/HID/MSD), and small graphical user interfaces rendered via PMP to external LCD controllers. DMA channels move peripheral data to RAM without CPU intervention, leaving headroom for application code. Typical applications include low-cost USB peripherals, capacitive touch human-machine interfaces (HMIs), audio/graphic control panels using external PMP-attached LCDs, sensor conditioning nodes with on-chip ADC, and general-purpose industrial controllers. The automotive-grade (-V) variant also suits body-electronics and HMI modules where AEC-Q100 qualification is required. Design consideration: with less than 0.5 mA/MHz active current, regulator choice should focus on low-noise, low-IQ LDOs; bulk decoupling of 10 µF ceramic plus 0.1 µF HF bypass near each VDD pin is recommended per the family datasheet. PPS routing must be reconfigured after each reset, so save PPS maps in non-volatile configuration.

PIC32MX110F016BT-V/ML

PIC32MX110F016BT-V/ML - 32-bit 40MHz MCU, 16KB Flash, AEC-Q100 | Microchip

The Microchip Technology PIC32MX110F016BT-V/ML is a 32-bit MIPS32 M4K RISC microcontroller running at 40 MHz, equipped with 16 KB of Flash program memory and 4 KB of SRAM, in a 28-pin QFN (6 x 6 mm) package with an exposed thermal pad. It operates from 2.3 V to 3.6 V and is qualified to AEC-Q100 for automotive applications, with a temperature range of -40 °C to +105 °C. The device integrates USB Full-Speed, two I²S/SPI modules, two UART/I²C modules, a Parallel Master Port (PMP) for graphics interfaces, and Peripheral Pin Select (PPS) for flexible routing of digital peripherals. A microcontroller (MCU) is an integrated circuit containing a CPU core, program and data memory, and programmable peripherals such as timers, communication interfaces, and analog blocks. PIC32MX110F016B sits inside the Microchip PIC32MX family, which in turn belongs to the broader 32-bit microcontroller category within the larger family of embedded processors that includes ARM Cortex-M, RISC-V, and MIPS architectures. MCUs are the central compute element of nearly every embedded system, executing firmware that interacts with sensors, actuators, displays, and external buses. Key features of this device include 21 general-purpose I/O pins, four DMA channels with automatic data size detection, a 10-bit ADC with multiple channels, and a Charge Time Measurement Unit (CTMU) for mTouch capacitive-touch sensing. Two separate PLLs (one for the CPU, one for USB) simplify mixed-clock designs, and five 16-bit timers cover a wide range of PWM and capture/compare tasks. The configurable Watchdog Timer with on-chip Low-Power RC oscillator enhances safety in noisy or low-power modes. The architecture combines a MIPS32 M4K core with Microchip's Peripheral Pin Select (PPS) fabric, allowing remapping of most digital peripherals to virtually any I/O pin. This is especially valuable in compact 28-pin designs where pin assignments often conflict with PCB layout, eliminating the need to re-spin a board for routing reasons. The integrated Full-Speed USB 2.0 device controller with on-chip transceiver simplifies connectivity without an external PHY. Typical applications include automotive body and infotainment modules, USB Human Interface Devices (HIDs) such as keyboards and mice, graphics interfaces via PMP for low-cost LCDs, capacitive touch panels using mTouch, and industrial control nodes. The wide operating voltage range and AEC-Q100 qualification make it well-suited to automotive and harsh industrial environments. When designing with this device, allocate PCB copper under the exposed pad for thermal relief and ensure the decoupling network uses 100 nF plus bulk capacitance within a few millimetres of the supply pins. The PPS feature must be configured at startup; forgetting to enable a peripheral's PPS mapping is a common first-time designer pitfall. This page synthesizes official Microchip specifications, AEC-Q100 automotive qualification details, drop-in PIC32MX1x0 family alternatives, and practical design notes that are not assembled in a single place on the manufacturer datasheet or distributor listing.
