PIC32MX250F128B-I/ML

PIC32MX250F128B-I/ML - 32-bit MCU 128KB Flash 40MHz | Microchip

The Microchip Technology PIC32MX250F128B-I/ML is a 32-bit MIPS M4K microcontroller running at 40 MHz, with 128 KB Flash and 32 KB SRAM, housed in a 28-pin 6x6 mm QFN package. The MIPS32 M4K core delivers up to 1.56 DMIPS/MHz (83 DMIPS total) and consumes only 0.5 mA/MHz active, providing a strong compute-to-power ratio for embedded designs. A 32-bit microcontroller (MCU) is an integrated processor core with on-chip memory, peripherals, and I/O that executes instructions on 32-bit-wide data paths. Within the broader taxonomy, PIC32MX sits at: 32-bit MCU -> MIPS M4K architecture -> Microchip PIC32 family -> embedded microcontroller -> semiconductor IC. The "MX" suffix indicates the mainstream PIC32 line, balancing peripherals, performance, and cost for general-purpose applications including audio, graphics, USB, and advanced analog interfaces. The PIC32MX250F128B integrates two I2S/SPI modules for codec/serial comms, a Parallel Master Port (PMP) for graphics, Peripheral Pin Select (PPS) for flexible I/O mapping, mTouch capacitive touch support, and 1 ns high-resolution time measurement. The on-chip 10-bit ADC reaches 500 ksps with a 16-channel input mux, and an on-die temperature diode supports internal thermal monitoring without an external sensor. Architecturally, the device uses a 5-stage pipeline Harvard MIPS core with hardware multiply/divide and a single-cycle MAC. Code execution is from Flash through a 16-entry instruction cache, accelerating loops common in DSP-style signal chains. USB 2.0 full-speed device/host/OTG and CAN 2.0B peripherals are available in sibling variants of the PIC32MX2xx family, while this "B" pinout exposes 21 general-purpose I/O pins. Typical applications include USB HID peripherals (audio interfaces, HID controllers), mTouch capacitive-button front panels, low-cost graphics HMI with PMP-driven LCDs, sensor-hub data acquisition with on-chip temperature, and industrial control with CAN-style comms. The wide 2.3-3.6 V supply range and 40 MHz operation also suit battery-powered IoT nodes. For layout, place a 10 uF + 0.1 uF decoupling pair within 5 mm of VDD/AVDD pins and keep the analog reference trace short. Note that the USB-equipped "50I" sibling at 50 MHz has a different supply budget, so verify firmware timing constraints when migrating between speed grades. This page consolidates distributor pricing, same-family pin-compatible alternatives, and practical design notes that go beyond the manufacturer datasheet to help engineers select and source this MCU efficiently.

The Microchip Technology PIC32MX250F128B-I/SP is a 32-bit RISC microcontroller built on the MIPS32 M4K core, delivering 50 MHz / 83 DMIPS of processing performance with 0.5 mA/MHz active current consumption. It integrates 128 KB of Flash program memory and 32 KB of SRAM in a 28-pin SPDIP through-hole package, making it well suited for industrial and consumer designs that benefit from breadboard-friendly pinouts and a wide peripheral set. An MCU (microcontroller unit) is a single-chip computer that combines a CPU core, non-volatile program storage (Flash), working memory (SRAM), and a rich set of on-chip peripherals such as timers, communication interfaces, ADCs, and I/O controllers. PIC32MX250 devices sit in Microchip's mid-range 32-bit PIC32MX family, sitting architecturally between 8-bit PIC16/PIC18 devices and higher-end Cortex-M-class parts. Their role in the broader hierarchy is: microcontroller -> embedded processor -> semiconductor IC. Key features include two I2S/SPI modules for audio codec and serial communication, Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) for graphics interfaces, mTouch capacitive touch support, 1 ns high-resolution time measurement, and on-chip temperature sensing. The device is also equipped with an USB OTG full-speed controller. The PIC32MX250F128B-I/SP architecture pairs the MIPS M4K core with a multi-channel DMA engine, a 10-bit 1 Msps ADC, five 16-bit timers (plus up to two 32-bit timers), and an input-capture/PWM module. This combination enables real-time deterministic control with minimal CPU overhead, while PPS allows remapping of digital peripherals to almost any I/O pin to ease PCB layout. Typical applications include industrial control (HMI panels, sensor hubs), USB device peripherals (HID, CDC, audio-USB), consumer audio with I2S codec interfaces, low-cost graphics with PMP-driven LCDs, and capacitive-touch user interfaces (keyboards, control surfaces, white goods). When designing with this part, pay attention to the 2.3 V to 3.6 V supply range, place a decoupling capacitor on Vcap, and use Microchip's MPLAB X IDE with Harmony framework for firmware development. JTAG/ICSP programming via PICkit or ICD supports in-circuit debugging. This page synthesizes distributor pricing, drop-in alternative listings, application examples, and design considerations that supplement, rather than duplicate, the Microchip datasheet.

PIC32MX250F128B-I/SS

PIC32MX250F128B-I/SS - 50MHz 32-bit MCU 128KB Flash SSOP-28 | Microchip

The Microchip Technology PIC32MX250F128B-I/SS is a 32-bit MIPS M4K RISC microcontroller operating at up to 50 MHz (83 DMIPS) with 128 KB Flash and 32 KB SRAM, housed in a 28-pin SSOP (Shrink Small Outline Package). It integrates Peripheral Pin Select (PPS) for flexible signal routing, two I2S/SPI modules for codec interfacing, a Parallel Master Port (PMP) for graphics, and a Charge Time Measurement Unit (CTMU) supporting mTouch capacitive touch sensing. A 32-bit microcontroller is a microprocessor with a 32-bit data path, registers, and address bus, paired with integrated Flash, SRAM, and peripherals on a single die. PIC32MX parts belong to the MIPS M4K architecture family, positioned between 8/16-bit MCUs and Cortex-M cores for embedded designs needing higher throughput (50 MHz/83 DMIPS) without the complexity of an MPU. They sit in the power-management-aware embedded control tier above PIC24/dsPIC and below Cortex-M4 in typical BOM cost. Key features of the 65-MHz MIPS32 M4K core: 0.5 mA/MHz typical active current, on-chip temperature sensor with 1 ns high-resolution time measurement, 1.5625 ms POR/BOR options, and a 16-bit wide instruction path. The 28-pin SSOP package is footprint-compatible with the PIC32MX150F128B-I/SS and PIC32MX230F064B-I/SS variants, enabling PCB reuse across the family. Operating voltage range is 2.3 V to 3.6 V, suitable for 3.3 V rails common in audio/graphics subsystems. The architecture uses a 5-stage pipeline, hardware multiply/divide, single-cycle bit manipulation, and atomic bit-set/clear operations on I/O registers. PPS remaps most digital peripherals to any remappable I/O pin, decoupling PCB constraints from firmware architecture. DMA is not present on this family (PIC32MX1xx/2xx), but the 50 MHz core, 32 KB SRAM, and PMP allow bit-mapped displays without an external controller. Typical applications include USB audio Class 2 DAC interfaces, low-cost graphics HMI panels via PMP, mTouch capacitive key/slider panels, low-cost DSP control, and chipKIT-style Arduino-compatible development boards. The USB 2.0 Full-Speed peripheral (device/host/OTG) is supported on the B-revision, distinguishing it from PIC32MX1xx without USB. Design consideration: Vcap requires a low-ESR 10 uF ceramic capacitor; PCB layout must keep the trace short. USB D+/D- impedance must be 90 ohm differential. Use ICSP pins (PGECx/PGEDx) carefully - they are multiplexed with JTAG on some PIC32 devices.

PIC32MX250F128B-V/SO

PIC32MX250F128B-V/SO - 50MHz 32-bit MCU 128KB Flash 28-SOIC | Microchip

The Microchip Technology PIC32MX250F128B-V/SO is a 32-bit MIPS M4K RISC microcontroller running up to 50 MHz with 83 DMIPS throughput, integrating 128 KB of Flash program memory and 32 KB of SRAM in a 28-pin wide-body SOIC package. The 'V' temperature grade supports an industrial operating range of -40C to +105C, while the 'B' suffix denotes the 28-pin variant of the PIC32MX1XX/2XX family. A 32-bit microcontroller (MCU) is a single-chip processor that integrates a CPU core, program memory (Flash), working memory (SRAM), and a rich set of peripherals on one die. Within the broader taxonomy, this part sits in the embedded 32-bit MCU category -> microcontroller -> semiconductor IC. The PIC32MX250 specifically targets low-power 32-bit applications where deterministic real-time performance, USB 2.0 full-speed device support, and audio/graphics interfaces are required. Key features include 128 KB self-programmable Flash with an endurance of 20,000 cycles, 32 KB SRAM, Peripheral Pin Select (PPS) for flexible I/O mapping, a Parallel Master Port (PMP) for graphics or external memory, two I2S/SPI modules for audio codecs, a 10-bit 1 Msps ADC with up to 28 channels, five 16-bit and two 32-bit timers, an 8-bit Parallel Port (EPMP), a USB 2.0 full-speed device peripheral, and mTouch capacitive touch support with 1 ns high-resolution time measurement. The 0.5 mA/MHz active current consumption enables battery-friendly designs. Architecturally the part uses the MIPS32 M4K core with a 5-stage pipeline, hardware multiply/divide, and a single-cycle 32-bit ALU. The 28-pin variant offers up to 21 general-purpose I/O (some are multiplexed with analog or oscillator functions), 4-wire SPI, two I2C, two UART, plus USB and PMP - giving designers strong interface density for its small SOIC footprint. Typical applications include USB HID devices (mouse, keyboard, custom peripherals), audio playback interfaces via I2S to external DACs/codecs, low-cost graphics with PMP-driven LCDs, mTouch capacitive touch buttons/sliders on user interfaces, industrial sensor hubs with USB diagnostics, and small embedded HMI panels. Industrial users often select this MCU for 3.3 V systems where USB and a rich peripheral set are required in a low-pin-count SOIC. Design consideration: at 50 MHz the part draws roughly 25 mA active plus USB suspend current; decoupling must include a bulk 4.7 uF + a 0.1 uF near each VDD/VSS pair, plus a 10 uF on VBUS when USB is used. The 28-pin SOIC has only 8 dedicated GPIO ports so plan pin mapping with the PPS feature in mind. This page synthesizes distributor pricing, drop-in alternative inventory, and practical design notes not found in the standalone Microchip datasheet, including same-package (28-SOIC) drop-in replacement candidates drawn from the broader PIC32MX1XX/2XX family.

Key features include 0.5 mA/MHz active current consumption, four 16-bit timers plus one 16-bit timer pair, five general purpose 16-bit timers/counters, mTouch capacitive touch hardware, a 1 ns resolution input capture, an on-chip temperature indicator, and JTAG/ICSP debug interfaces. The -V suffix denotes the V temperature grade (operating range -40C to +105C). The MIPS M4K core with 5-stage pipeline executes most instructions in one cycle and supports 83 DMIPS at 50 MHz; this part is rated 40 MHz operation. USB OTG, PMP, and PPS together allow flexible pin mapping without board rework. 32 KB SRAM supports reasonable RTOS or audio buffer workloads typical of USB audio class or USB HID designs. Typical applications include USB peripherals (keyboards, mice, audio class, HID), capacitive touch human-machine interfaces, small graphical LCDs via PMP, low-cost audio codec bridges, and embedded control with on-chip USB. Designers should pay attention to the 28-SPDIP through-hole footprint - the same silicon is offered in SOIC-28 and QFN-28 packages for SMD designs. The Vcap pin requires an 8 uF-10 uF low-ESR decoupling capacitor to stabilize the internal 1.8 V core regulator; omitting it causes erratic operation.

The part operates from 2.3 V to 3.6 V over the -40 °C to +105 °C industrial temperature range and consumes 0.5 mA/MHz in active mode, making it well suited to low-power embedded designs that need USB and graphics peripherals on a single chip. What is a PIC32 microcontroller? PIC32MX devices are 32-bit MIPS-based microcontrollers from Microchip Technology belonging to the broader PIC MCU family. They occupy the mid-range of Microchip's 32-bit portfolio, sitting between the smaller PIC32MM and the more capable PIC32MZ. Their role in the system hierarchy is: MCU -> 32-bit microcontroller -> embedded processor -> semiconductor. PIC32MX parts integrate high-performance CPU cores with rich peripherals such as USB, I2S, PMP, and ADC, enabling designers to consolidate what previously required multiple ICs onto one MCU. Key features of the PIC32MX250F128B-V/SS include two I2S/SPI modules for codec and serial communications, Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) for graphics interfaces, and mTouch capacitive touch sensing support. The CTMU peripheral provides 1 ns high-resolution time measurement, and an on-chip temperature sensor enables die-level thermal monitoring. The 10-bit ADC offers up to 13 input channels and 1 Msps conversion rate for mixed-signal acquisition. Architecturally, the device uses a Harvard-style MIPS32 core with single-cycle multiplication, 5-stage pipeline, and a dedicated prefetch cache, achieving 1.5 DMIPS/MHz. Hardware multiply/divide and a single-cycle bit manipulation engine accelerate DSP-style algorithms. The USB 2.0 Full-Speed device controller with on-chip transceiver eliminates external PHY components, while the PMP bus and I2S peripherals enable direct glueless interfaces to TFT displays and audio codecs. Typical applications include USB HID peripherals, audio processing devices, graphics-display HMI modules, capacitive touch user interfaces, and industrial sensor hubs. The wide temperature range and rich peripheral set make it a strong fit for medical instruments, building automation, and consumer appliances requiring USB connectivity plus user feedback. When designing with the PIC32MX250F128B-V/SS, ensure the VCAP pin decoupling is implemented exactly as specified (typically 10 µF ceramic) because the internal 1.8 V core regulator requires this for stability. Use the PPS feature to remap peripherals, but verify pin assignments during code development because not every peripheral maps to every I/O.

PIC32MX250F128C-50I/TL

PIC32MX250F128C-50I/TL - 50MHz 128KB Flash 32-bit MCU | Microchip

The Microchip Technology PIC32MX250F128C-50I/TL is a 32-bit RISC microcontroller based on the MIPS32 M4K core, delivering 50 MHz / 83 DMIPS performance with 128 KB of Flash program memory and 32 KB of SRAM, housed in a 36-pin VTLA (5x5 mm) surface-mount package. It integrates USB 2.0 full-speed OTG, two I2S/SPI modules for audio codec interfacing, a Parallel Master Port (PMP) for graphics, a Charge Time Measurement Unit (CTMU), and a 10-bit ADC. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and a rich set of on-chip peripherals. The PIC32MX family sits in the 32-bit microcontroller hierarchy: it uses a MIPS32 RISC core rather than an 8-bit PIC core, giving a step change in performance and addressable memory. The 'PIC32' family descends from the original PIC 8-bit line and provides higher compute density for embedded designs that require networking stacks, graphical user interfaces, or audio processing at low BOM cost. Within Microchip's portfolio, the PIC32MX1xx/2xx sub-family balances peripheral integration with small 28-44 pin packages, while the PIC32MM/MZ sub-families target ultra-low-power or high-performance designs respectively. Key features include 23 general-purpose I/O pins (per datasheet), 0.5 mA/MHz typical core current consumption, on-chip temperature sensor, RTCC for real-time clock with backup, Peripheral Pin Select (PPS) for flexible peripheral-to-pin routing, and 1.5 Msps 10-bit ADC with up to 28 analog inputs. The device supports mTouch capacitive-touch sensing via the CTMU, providing 1 ns resolution time measurement for sliders and buttons. USB 2.0 full-speed OTG, UART, SPI, I2C, and PMP give a broad connectivity surface for graphics and audio subsystems. Architecturally, the PIC32MX250F128C implements a 5-stage MIPS32 M4K pipeline with single-cycle multiply and hardware divide. The 50 MHz core couples to dedicated DMA channels that move data between peripherals and memory without CPU intervention, freeing the core for application logic and accelerating audio/USB throughput. The 36-pin VTLA package reduces PCB area versus 44-pin TQFP alternatives. Typical applications include USB-audio interfaces, low-cost HMI panels using PMP-driven LCDs, capacitive-touch control panels, audio DAC/ADC front ends with I2S, and industrial control nodes requiring RTCC-based timekeeping. The wide 2.3V-3.6V supply range supports single-cell Li-ion systems.

PIC32MX250F128C-I/TL - 32-bit MCU 128KB Flash 40MHz USB | Microchip

The Microchip PIC32MX250F128C-I/TL is a 32-bit MIPS32 M4K microcontroller with 128KB Flash, 32KB SRAM, USB 2.0 full-speed device/host/OTG, and audio/graphics interfaces, housed in a 36-pin VTLA (5x5 mm) surface-mount package with exposed pad. It runs at 40 MHz core clock, provides 19 general-purpose I/O, and integrates Peripheral Pin Select (PPS), a Parallel Master Port (PMP) for graphics, two I2S/SPI modules for codec interfacing, a 10-bit 1 Msps ADC with up to 13 channels, and mTouch capacitive-touch support. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), peripherals, and I/O. The PIC32MX250 family sits within Microchip's PIC32MX tier of 32-bit MIPS-based microcontrollers, which itself belongs to the broader category of microcontrollers -> embedded processors -> semiconductors. PIC32MX parts target applications that need more performance than 8/16-bit MCUs while keeping the PIC ecosystem (MPLAB X IDE, Harmony, MCC code configurator) and a clear migration path across the PIC32 family. Key differentiating features include on-chip USB 2.0 full-speed device/host/OTG (rare in this flash/RAM tier), 4-wire Parallel Master Port for direct graphics LCD driving without external controllers, and dual I2S/SSI interfaces aimed at audio codecs. The part operates from 2.3V to 3.6V with industrial -40C to +85C temperature range, uses an internal 8 MHz Fast RC oscillator with PLL up to 40 MHz, and supports 5 general-purpose 16-bit timers plus Input Capture and Output Compare channels. The PIC32MX250F128C uses the MIPS32 M4K core with 5-stage pipeline, single-cycle multiply, hardware multiply-accumulate, and a 1.5 DMIPS/MHz figure (delivering 60 DMIPS at 40 MHz). It includes a 32-channel DMA controller, JTAG and 2-wire ICSP programming/debug, and an on-chip temperature indicator for thermal monitoring. The VTLA-36 (5x5 mm) package has a thermal pad that must be soldered to the PCB ground pour for proper thermal dissipation. Typical applications include USB audio devices (USB headsets, USB DACs), consumer audio products with I2S codecs, low-cost graphical HMI panels (using PMP+LCD), capacitive-touch human interfaces (keyboards, sliders), and small USB peripherals such as HID game controllers, data loggers, or CDC devices. The combination of USB OTG + graphics PMP + I2S makes the PIC32MX250 particularly attractive for cost-sensitive multimedia consumer nodes. When designing with this part, allocate generous PCB copper under the exposed pad - the VTLA package dissipates heat through this pad. Add a 4.7uF + 0.1uF decoupling pair at every VDD pin. For USB applications, the internal USB transceiver requires a 48 MHz clock derived from the PLL with 0.25% accuracy; a 12 MHz crystal or 8 MHz + PLL configuration is recommended. JTAG and ICSP share pins, so plan the programming header to avoid contention with user I/O.

AEC-Q100 qualification makes the V-temperature variant suitable for automotive ECUs and body controllers. Architecture-wise, the M4K core fetches fixed-length 32-bit instructions and provides a hardware multiplier, zero-overhead loops, and a shadow register set for real-time interrupt latency. PPS allows remapping of most digital peripherals to nearly any I/O pin, simplifying PCB layout and enabling reuse across product variants. Typical applications include USB peripherals (HID, CDC, MSD class devices), audio interfaces with I2S codecs, low-cost graphics terminals, capacitive touch HMI panels, automotive body controllers, and industrial sensors with USB diagnostics. The AEC-Q100 rating extends suitability to infotainment accessory controllers and OBD-II dongles. When designing with this part, ensure the VTLA exposed pad is soldered to a sufficient copper pour (minimum 25 mm^2, recommended >100 mm^2) for thermal dissipation - the small package dissipates more heat than its size suggests at high CPU load. Decouple VDD/VBUS with 100 nF ceramic capacitors within 2 mm of each supply pin, and route the USB DP/DM traces as a 90 ohm differential pair.

PIC32MX250F128D-V/TL - 32-bit MCU 128KB Flash USB OTG | Microchip
PIC32MX250F128D-V/TL

PIC32MX250F128D-V/TL - 32-bit MCU 128KB Flash USB OTG | Microchip

The Microchip Technology PIC32MX250F128D-V/TL is a 32-bit MIPS32 M4K microcontroller with 128 KB Flash and 32 KB SRAM, running at up to 40 MHz core / 50 MHz max, in a 44-pin VTLA exposed-pad surface-mount package. It integrates USB 2.0 full-speed device/host/OTG, two I2S/SPI modules, a Parallel Master Port (PMP) for graphics, Peripheral Pin Select (PPS), mTouch capacitive touch support, a 1 ns resolution input capture, and an on-chip temperature sensor. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripheral interfaces. The PIC32MX1XX/2XX family sits within the broader MIPS32 architecture hierarchy and is designed for cost-sensitive embedded applications that still require USB connectivity and graphics peripherals. Within Microchip's portfolio this part bridges 8-bit PIC16/PIC18 designs and higher-end Cortex-M alternatives, offering the PIC toolchain (MPLAB X, XC32) and a mature DSP/USB library stack. Key specifications include 83 DMIPS core performance (1.56 DMIPS/MHz), 0.5 mA/MHz typical active current, 2.3 V to 3.6 V supply, ten 16-bit timers plus two 32-bit timers, a 10-channel 10-bit ADC at 1 Msps, and an AEC-Q100 automotive grade rating. The 44-pin VTLA package has 34 general-purpose I/O pins and measures 8 x 8 mm with a 0.65 mm pitch and 0.90 mm profile, including an exposed thermal pad that must be soldered to the ground plane for proper thermal dissipation. The MIPS32 M4K core uses a 5-stage pipeline and supports MIPS16e compressed instructions to reduce code size by up to 40%. Programmable PPS remaps most digital peripheral inputs/outputs to a wide range of physical pins, simplifying PCB routing and allowing late-stage BOM changes without board respins. The USB 2.0 full-speed OTG controller handles Host, Device, and On-The-Go roles in firmware, and the PMP bus drives external graphical LCDs. Typical applications include USB HID peripherals (HID keyboards, mice, custom interfaces), embedded audio streamers via I2S, low-cost graphical HMI panels with PMP-driven LCDs, capacitive touch control surfaces using mTouch, and AEC-Q100 automotive body and infotainment sub-modules. Designers building on this part should pay attention to the 5 V tolerance of I/O pins, the need for a 24 MHz primary oscillator to derive USB clocks, and the exposed pad requirement for thermal management.

Key features include five 16-bit timers/counters, a 16-channel 10-bit ADC capable of 1 Msps conversion, CTMU for capacitance measurement, an analog comparator, and a charge-time measurement unit for mTouch. The USB 2.0 full-speed On-The-Go controller adds tethered/hostless connectivity, while two I2S/SSI peripherals support audio CODECs and serial DACs. PMA graphics interfacing through PMP enables direct connection to QVGA displays without external RAMDACs. The PIC32MX250F128D is built on a 0.18 µm flash process with the MIPS32 M4K core delivering 1.56 DMIPS/MHz at 50 MHz. Hardware-level PPS remapping of digital peripherals to nearly any I/O pin simplifies PCB routing. Five 16-bit timers support input capture, output compare, and quadrature encoding. The integrated 10-bit ADC supports up to 28 analog inputs and 1 Msps sampling. USB OTG, two I2S, two I2C, two UART/USART peripherals, and an SPI interface provide flexible connectivity. Typical applications include USB peripherals, audio interfaces, low-cost graphics HMI, mTouch capacitive touch sensing, and industrial control. The USB OTG and PMP graphics interface make it well-suited for embedded hosts, while the CTMU supports capacitive buttons and sliders in human-machine interfaces. When designing with this part, note that the 44-pin VTLA package shares its pinout with the PIC32MX250F128D-50I/TL non-T variant. Operating voltage is 2.3V-3.6V; a 3.3V LDO with adequate decoupling is required for noise-sensitive applications. This page combines verified distributor pricing, same-package drop-in alternatives, and practical design notes that are not aggregated in the manufacturer datasheet alone.

The Microchip Technology PIC32MX250F128DT-I/TL is a 32-bit MIPS32 M4K RISC microcontroller running at 40 MHz with 128 KB Flash and 32 KB SRAM, housed in a 44-pin VTLA (6x6 mm) package with exposed pad. It integrates a USB 2.0-compliant full-speed device/host/OTG controller, two I2S/SPI modules, and a Parallel Master Port (PMP) for graphics interfaces. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripherals onto one silicon die. The PIC32MX family belongs to the broader taxonomy of embedded processors: microcontroller -> 32-bit MCU -> MIPS-based MCU -> Microchip PIC32MX series. These devices target applications requiring deterministic real-time control combined with rich connectivity, sitting between 8-bit PIC16/PIC18 MCUs and the higher-performance ARM Cortex-M based SAM family. Key features include Peripheral Pin Select (PPS) for flexible peripheral-to-pin mapping, five 16-bit timers/capture/compare, a 10-bit 1 Msps ADC with up to 13 input channels, mTouch capacitive touch sensing, and on-chip temperature measurement. The device supports 2.3V to 3.6V single-supply operation with 0.5 mA/MHz active current consumption, and provides JTAG and 2-wire ICD debugging interfaces. The architecture uses a 5-stage pipeline MIPS32 M4K core with hardware multiply/divide, achieving 1.56 DMIPS/MHz (83 DMIPS at 50 MHz). The 32 KB SRAM is partitioned for instruction and data, and the 128 KB Flash supports self-programming under firmware control for in-field updates. Typical applications include USB audio class devices, USB HID peripherals, embedded graphics with PMP-driven TFT displays, capacitive touch user interfaces, and low-power sensor hubs. The combination of USB OTG, audio I2S, and PMP makes this MCU a strong fit for multimedia and human-machine interface designs. When designing with this part, pay close attention to VTLA PCB land pattern requirements and thermal pad soldering. The USB peripheral requires precise 48 MHz clocking from the on-chip PLL, and the JTAG pins are multiplexed on I/O ports, so debugger sharing must be planned at the board level. This page synthesizes distributor pricing, parametric drop-in alternatives from the same PIC32MX2XX family, and practical design considerations not found in the standalone datasheet.

PIC32MX250F128DT-V/ML

PIC32MX250F128DT-V/ML - 40MHz 32-bit MCU, USB, 128KB Flash | Microchip

The Microchip Technology PIC32MX250F128DT-V/ML is an AEC-Q100-qualified 32-bit MIPS32 M4K microcontroller running at 40 MHz (50 MHz/83 DMIPS capable) with 128 KB Flash and 32 KB SRAM, housed in a 44-pin QFN (8x8 mm) exposed-pad package. It integrates a USB 2.0 full-speed device/host/OTG controller, two I2S/SPI modules, a Parallel Master Port (PMP) for graphics, and Peripheral Pin Select (PPS) for flexible pin mapping, making it a single-chip solution for embedded designs that need both connectivity and a small footprint. A 32-bit microcontroller (MCU) is a programmable system-on-chip that integrates a CPU core, program Flash, data SRAM, and a rich peripheral set in one device. PIC32MX parts are Microchip's MIPS32-based 32-bit MCU family that bridges 8/16-bit PIC legacy code to modern ARM-class 32-bit workloads, occupying the power-management IC / microcontroller tier within the semiconductor hierarchy. Within that hierarchy, the PIC32MX250 sub-family is the entry-level 32MX USB-enabled variant targeting cost-sensitive embedded graphics, HMI, and audio designs. Key features include 34 usable I/O lines, supply voltage 2.3 V to 3.6 V, 1 ns high-resolution timer capture, on-chip temperature sensor, mTouch capacitive-touch hardware, five 16-bit general-purpose timers, a 10-bit 1 Msps ADC (up to 13 channels), and CTMU/ICSP trace support. The -V suffix denotes the -40 C to +105 C automotive/industrial operating range and the T suffix denotes tape-and-reel packaging. Architecturally, the device uses a single-core MIPS32 M4K RISC pipeline with hardware multiply/divide and a tightly-coupled prefetch module; combined with the PMP and USB-OTG, it enables direct driving of graphical LCDs and USB peripherals without external bus bridges. Compared with 8-bit PIC16/PIC18 parts, the PIC32MX250 executes instructions ~10x faster and offers substantially more deterministic interrupt response thanks to a hardware shadow register set. Typical applications include automotive infotainment and HVAC human-machine interfaces, USB HID peripherals (keyboards, mice, custom input devices), portable medical measurement instruments, industrial control panels with capacitive touch, graphics terminal modules, and low-cost audio docking stations with I2S codec connectivity. A key design tip is to follow Microchip's "Minimum USB Connection Requirements" (one VBUS sense resistor, ESD protection on D+/D-, and 47 nF decoupling on VUSB) to pass USB compliance on the first revision, and to allocate the exposed thermal pad as a single solid copper pour with 9 thermal vias to dissipate the ~140 mW typical operating power.
