PIC32MX150F128BT-I/ML

PIC32MX150F128BT-I/ML - 32-bit MCU 128KB Flash 40MHz | Microchip

The Microchip PIC32MX150F128BT-I/ML is a 32-bit MIPS32 M4K RISC microcontroller with 128 KB Flash, 32 KB SRAM, and 40 MHz maximum CPU clock, housed in a 28-pin QFN (6x6 mm) package with exposed pad for thermal dissipation. It operates from 2.3 V to 3.6 V and integrates two I2S/SPI modules, two UART, two I2C, a USB 2.0 Full-Speed device peripheral, a Parallel Master Port (PMP), and a 10-bit 1 Msps ADC with up to 13 channels. What is a 32-bit PIC microcontroller? A 32-bit MCU is a microcontroller whose arithmetic logic unit, registers, and data bus are all 32 bits wide, enabling single-cycle multiplications, larger linear address spaces, and significantly higher throughput than 8-bit or 16-bit alternatives. The PIC32MX family is Microchip Technology's migration path from the PIC16/PIC24 lines to true 32-bit performance while preserving Peripheral Pin Select (PPS) flexibility and the MPLAB X / Harmony tool-chain ecosystem. Positioned in the hierarchy: PIC32MX150F128B -> PIC32MX1xx family -> PIC32MX series -> PIC32 family -> 32-bit microcontroller -> microcontroller -> embedded semiconductor. Key features of this part include 21 general-purpose I/O lines, five 16-bit timers (with Input Capture and Output Compare), a 5-channel DMA controller, mTouch capacitive-touch hardware, an on-chip temperature sensor, and pin remapping via PPS. The MIPS32 M4K core delivers 1.56 DMIPS/MHz (approx. 52 DMIPS at 40 MHz), bringing genuine 32-bit performance to cost-sensitive designs. The 128 KB Flash supports self-programming and the 32 KB SRAM comfortably accommodates TCP/IP stacks or USB audio class frames. Technical depth: the silicon integrates dedicated PLLs for the system clock and the USB clock, allowing the 48 MHz USB clock to be generated without an external crystal when the system uses the internal 8 MHz oscillator plus PLL. Two Comparators and a CTMU (Charge Time Measurement Unit) round out the analog front end, while JTAG and two-wire ICSP provide debug. Typical applications include USB audio interfaces (USB headphone DAC), capacitive touch panels, low-cost graphics with PMP-driven TFTs, sensor hubs, and battery-powered IoT nodes. Pairing it with a USB device stack and the on-chip PMP removes the need for an external display controller. When designing with this device, route the exposed pad (EP) to a continuous ground plane with multiple thermal vias to keep theta_JA within the 28-QFN thermal envelope; this is the single most common layout pitfall on QFN packages.

PIC32MX150F128BT-I/SO

PIC32MX150F128BT-I/SO - 40MHz 32-bit MCU 128KB Flash | Microchip

The Microchip PIC32MX150F128BT-I/SO is a 32-bit MIPS32 M4K RISC microcontroller running at up to 40 MHz, integrating 128 KB of Flash program memory and 32 KB of SRAM in a 28-pin SOIC package. The 'BT' suffix denotes tape-and-reel packaging, the 'I' indicates the industrial -40C to +85C temperature range, and the 'SO' specifies the wide-body SOIC-28 outline. The device operates from a single 2.3V to 3.6V supply and consumes less than 0.5 mA/MHz active, making it well suited to battery-aware embedded designs. A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and a rich set of peripherals on one silicon die. Within the embedded hierarchy it sits at the same tier as 16-bit MCUs and 8-bit MCUs but offers higher computational throughput, larger addressable memory, and typically richer peripheral integration. PIC32MX1xx/2xx devices occupy the low-power, low-pin-count position of the PIC32 family, sitting between the smaller PIC24 16-bit line and the higher-pin-count PIC32MX3xx/4xx/5xx/6xx/7xx families. Key features include the MIPS32 M4K core with 5-stage pipeline and hardware multiply/divide, two I2S/SPI modules for audio codec interfaces, two UART and two I2C peripherals, a Parallel Master Port (PMP) for graphics displays, and up to four DMA channels with automatic data-size detection. Peripheral Pin Select (PPS) remaps most digital peripherals to a wide choice of physical pins, easing PCB layout. Five 16-bit timers, a 10-bit 1 Msps ADC with up to 13 channels, on-chip temperature sensing, and mTouch capacitive-touch support round out the analog and timing resources. A separate PLL for the USB clock allows full-speed USB 2.0 device operation independently of the system clock. The architecture uses a Harvard-style bus with separate program Flash and SRAM paths, and a configurable prefetch module that hides Flash latency at high clock rates. The 128 KB Flash is organized for in-application programming through self-write rows, and the device supports run-time DMA-driven peripheral servicing with minimal CPU intervention. Interrupt latency is deterministic, which simplifies real-time control loops. Typical applications include low-cost USB audio peripherals, small graphical HMI panels using PMP, capacitive-touch user interfaces, sensor hubs, and general-purpose 32-bit control replacing older PIC24 or 8051 designs. Designers migrating from 8-bit PIC16/PIC18 parts gain an immediate 30x-50x instruction throughput uplift while keeping the MPLAB X toolchain and Harmony framework. Design consideration: the 28-pin SOIC does not expose every peripheral on a fixed pin. Plan your pin map using PPS early in the schematic phase, and budget for an external 8 MHz primary crystal if USB accuracy is required - the internal 8 MHz Fast RC is insufficient for full-speed USB without software calibration against the USB SOF. This page synthesizes distributor pricing, drop-in package-equivalent alternatives, and practical design notes that are not collected in any single manufacturer datasheet, helping engineers shorten the BOM validation and second-source qualification cycle.

A PIC32MX-series microcontroller is a 32-bit RISC MCU built on the MIPS microAptiv (M4K) core, sitting in Microchip's hierarchy of 32-bit embedded controllers: PIC32MX -> PIC32 -> 32-bit MCU -> microcontroller -> semiconductor. Compared with 8-bit PIC16/PIC18 devices, the PIC32MX delivers deterministic interrupt latency, full C-language efficiency, and on-chip peripherals that previously needed glue logic - making it a mainstream choice for human-machine interface (HMI), audio decoding, and USB device applications. Key features include two I2S/SPI interfaces for codec and serial communications, Peripheral Pin Select (PPS) for flexible signal routing, mTouch capacitive touch buttons and sliders, on-chip temperature measurement, and a Parallel Master Port for graphics interfaces. Hardware trace and JTAG boundary-scan interfaces support development, and the wide-body 28-SOIC footprint is friendly to through-hole DPCB prototypes and hand-rework designs. The device uses a Harvard-architecture bus with separate program Flash (128 KB) and data SRAM (32 KB) for deterministic code-fetch and zero-wait-state operation up to 40 MHz. Integrated DMA, up to 5 timers, PMP, I2S/SPI, USB, and ADC peripherals enable designers to consolidate multiple external components onto a single chip, reducing BOM cost and PCB area. Less than 0.5 mA/MHz active current keeps thermal dissipation low in compact sealed enclosures. Typical applications include USB audio bridges, capacitive touch human-machine interfaces, graphic LCD control via PMP, low-cost sensor data acquisition, and industrial control panels. The V-temp range and automotive pedigree make the -V/SO grade especially suited for AEC-Q100 design chains and automotive-grade subsystems where higher temperature reliability is required. When designing with the PIC32MX150F128BT-V/SO, confirm that your toolchain - MPLAB X IDE, XC32 compiler, and Harmony framework - supports the exact silicon revision (B revision). Route analog inputs away from PWM outputs to minimize ADC crosstalk, and use 100 nF + 10 uF decoupling close to each VDD/VSS pair. Boundary-scan is enabled through dedicated JTAG pins for in-circuit test coverage.

Key features include two I2S/SPI modules for codec and serial audio, Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) for graphics and external memory interfaces, a Charge Time Measurement Unit (CTMU) supporting mTouch capacitive touch sensing with 1 ns resolution, on-chip temperature measurement, and USB 2.0 full-speed device/host/OTG. The part operates from 2.5 V or 3.3 V with less than 0.5 mA/MHz active current consumption, suiting portable and USB-powered designs. Architecturally, the M4K core offers single-cycle hardware multiply/divide and a 5-stage pipeline, providing deterministic interrupt latency. The 128 KB Flash and 32 KB SRAM are accessible through the unified 32-bit bus, while the PMP module can address up to 16 MB of external memory in master mode - useful for graphics and audio buffer extensions. Typical applications include USB audio devices (headsets, dongles, MIDI controllers), capacitive touch user interfaces (mTouch sliders and buttons), low-cost graphics HMI with PMP-connected TFT panels, industrial control front-ends with USB connectivity, and portable consumer electronics requiring 32-bit math without ARM licensing overhead. When designing with this device, plan I/O carefully: PPS lets remap most digital peripherals to alternate pins, but analog and oscillator pins are fixed. Use the exposed pad (EP) of the QFN-44 package as the primary thermal and ground return path - it must be soldered to a continuous copper pour for rated performance.

It is part of the PIC32MX1XX/2XX family, which integrates USB 2.0 (Full-Speed), two I2S/SPI modules, a Parallel Master Port (PMP), a 10-bit ADC, and a Charge Time Measurement Unit (CTMU) for mTouch capacitive sensing. A 32-bit microcontroller (MCU) is a programmable system-on-chip that combines a CPU core, volatile memory (SRAM), non-volatile memory (Flash), and multiple peripheral interfaces on a single silicon die. Within the broader hierarchy of microcontrollers, the PIC32MX family belongs to the 32-bit MCU category, itself a sub-category of microcontrollers, embedded processors, and ultimately semiconductors. 32-bit MCUs are typically chosen over 8-bit or 16-bit parts when applications require more than 64 KB of code space, hardware USB, or graphics-oriented peripherals such as PMP for TFT displays. Key features of the PIC32MX150F128D-50I/TL include a low active current of less than 0.5 mA/MHz at full speed, Peripheral Pin Select (PPS) for flexible peripheral-to-pin mapping, two I2S/SPI modules for codec and serial communication, PMP for graphics interfaces, support for mTouch capacitive touch buttons and sliders, and a high-resolution 1 ns time-measurement capability. The device operates from 2.3 V to 3.6 V and supports industrial temperature range parts (-40C to +85C). The architecture combines a MIPS32 M4K RISC core with a 5-stage pipeline, Harvard bus structure, single-cycle hardware multiply/divide, and tightly coupled peripherals. PPS remapping allows designers to assign peripherals to available I/O pins without redesigning the PCB. The 10-bit ADC provides up to 1 Msps conversion with on-chip sample-and-hold, and the CTMU enables capacitive touch measurement, time-of-flight, and accurate pulse generation. Typical applications include USB audio devices, mTouch capacitive touch panels, low-cost graphics displays via PMP, sensor hubs, and general-purpose embedded control. The wide peripheral mix makes this MCU particularly attractive for cost-sensitive consumer electronics requiring USB plus graphics in a single chip. When designing with the PIC32MX150F128D-50I/TL, plan the decoupling network with a 0.1 uF capacitor on each VDD pin and a bulk 4.7 uF to 10 uF tantalum/ceramic capacitor near the regulator.

What is a 32-bit MCU? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripherals such as timers, ADCs, and communication interfaces. The PIC32MX1XX/2XX family uses the MIPS32 M4K core, placing these parts in the microcontroller -> 32-bit MCU -> MIPS-based MCU -> embedded controller taxonomy, and within Microchip's broader portfolio they sit alongside the PIC24 and dsPIC families as general-purpose embedded controllers with DSP-class throughput.

PPS allows remapping of digital peripheral signals to most I/O pins, simplifying PCB routing in densely packed designs. Architecturally, the part uses a 5-stage pipeline MIPS32 M4K core with hardware multiply/divide and a Prefetch Cache Module that fetches 16-bit words from Flash and presents 32-bit instructions to the core. The dual-bank Flash with live-update support enables in-field firmware upgrades, and the 32 KB SRAM provides ample headroom for USB stacks, graphics framebuffers, and audio processing buffers. Typical applications include USB audio devices (USB speakers, headphones, and headsets), low-cost graphics HMI with PMP-driven TFT panels, capacitive touch key/slider front panels using CTMU, industrial control with on-chip 10-bit ADC, and consumer devices requiring USB connectivity. The wide peripheral mix and USB make the part a single-chip solution for many USB+graphics products. A key design consideration is that the 44-QFN part exposes fewer I/O than the 64-pin variants; designers needing more pins should consider the PIC32MX150F128D-I/PT (44-TQFP, same pinout assignment) or migrate to PIC32MX250/270 64-pin devices for additional peripherals. Ensure VUSB decoupling follows the USB specification and the VBAT/AVDD rails are properly sequenced.

Key features include MIPS32 M4K 32-bit core at 40 MHz, 128 KB Flash with 32 KB SRAM, 4-channel hardware DMA with automatic data-size detection, Peripheral Pin Select (PPS) for flexible pin mapping, two UART, two I2C, two I2S/SPI modules, a Parallel Master Port (PMP) for graphics, a 1 ns resolution hardware timer for time measurement, and on-chip temperature measurement. The AEC-Q100 grade and -40C to +105C range suit automotive and industrial environments. Architecturally the device uses a 5-stage pipeline M4K core with separate instruction and data Flash buses, achieving 1.56 DMIPS/MHz. The Dual-bank Flash supports live update via the panel A/B partitioning scheme, and PPS remaps most digital peripherals to any I/O pin, simplifying PCB routing in space-constrained designs. Typical applications include automotive HMI and body controllers, industrial control panels with graphical displays, USB-to-UART bridges, low-cost audio processing, capacitive touch (mTouch) interfaces, and sensor hubs. The combination of 128 KB Flash and 32 KB RAM is enough for mid-size state-machine firmware, USB stacks, and small RTOS kernels (FreeRTOS port available). When designing with this device, remember that 'V' in the suffix indicates the -40C to +105C (V-temp) grade, 'DT' indicates tape and reel with 128 KB Flash, and 'ML' indicates the 44-pin QFN package. A 4-layer PCB with a continuous ground pour under the exposed pad is essential for thermal dissipation.

PIC32MX150F256H-50I/MR

PIC32MX150F256H-50I/MR - 32-bit 50MHz 256KB Flash MCU | Microchip

The Microchip PIC32MX150F256H-50I/MR is a 32-bit RISC microcontroller built on the MIPS32 M4K core, delivering up to 50 MHz / 83 DMIPS of processing performance with 256 KB of Flash program memory and 32 KB of SRAM, housed in a 64-pin QFN (MR) 9x9 mm package with an exposed thermal pad. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O on one silicon die. The PIC32MX family sits in the broader taxonomy as: 32-bit microcontroller -> RISC MCU -> embedded controller -> semiconductor IC. Within Microchip's portfolio, the PIC32MX1xx/2xx/5xx series represents the mid-range 32-bit tier, optimized for cost-sensitive applications that still require USB, CAN, or graphics peripherals. Compared with 8-bit PIC16/PIC18 MCUs, the PIC32MX offers five to ten times the processing throughput and large memory footprints, while remaining more power-efficient and easier to use than high-end Cortex-M4 devices. Key differentiating features of this part include Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) with dual buffers for graphics interfaces, three I2S/SPI modules for codec connectivity, a 10-bit 1 Msps ADC with up to 28 channels, a 16-bit Parallel Master Port, and an integrated mTouch capacitive-touch sensing peripheral via CTMU. The PPS feature in particular allows remapping of digital peripheral functions to alternate pins, simplifying PCB layout and BOM consolidation. Architecturally, the device combines a Harvard-style bus with unified 32-bit instruction and data paths, hardware multiply/divide, single-cycle MAC operations, a 5-stage pipeline, and tightly-coupled prefetch cache for Flash. The 64-pin QFN package exposes 53 digital I/O, USB 2.0 full-speed OTG, two I2C, two UART, four SPI, and two I2S interfaces, plus PMP and a 10-bit ADC, providing extensive connectivity for mixed-signal embedded designs. Typical applications include USB audio peripherals with codec interfacing, industrial control HMI panels using PMP graphics, consumer appliances with capacitive-touch interfaces, low-cost motor control, sensor aggregation nodes with USB diagnostics, and educational/development platforms where the PICkit 3 or ICD 3 toolchain is already in place. When designing with the PIC32MX150F256H-50I/MR, note the -50 speed grade limits operation to 50 MHz (versus 70 MHz on -70 variants). Decoupling requires 100 nF on every VDD/AVDD pair plus a bulk 4.7 uF; the exposed thermal pad must be soldered to a continuous ground plane for thermal dissipation and reduced ground inductance.

PIC32MX150F256H-I/MR

PIC32MX150F256H-I/MR - 256KB Flash 32-bit MCU, 50MHz | Microchip

The Microchip PIC32MX150F256H-I/MR is a 32-bit MIPS M4K microcontroller with 256KB Flash and 32KB SRAM in a 64-pin QFN (9x9 mm) package. The device runs up to 50 MHz (83 DMIPS) on a 2.3V-3.6V supply and integrates 53 general-purpose I/O pins, two I2S audio interfaces, four SPI modules, two I2C buses, and a Parallel Master Port (PMP) for graphics. Industrial-grade -40C to +85C temperature range and the M4K MIPS32 core make this MCU a mainstream embedded control + HMI DSP hybrid. The MR suffix denotes 64-lead QFN with exposed pad. What is a PIC32MX microcontroller? The PIC32MX family sits inside Microchip's broader PIC32 portfolio - a line of 32-bit MIPS-based microcontrollers that bridges the gap between 8/16-bit PIC MCUs and the higher-performance Cortex-M class. PIC32MX devices integrate DSP instructions (MIPS M4K with multiply-add pipelines), audio interfaces (I2S), and graphics peripherals (PMP) that let a single chip drive HMI panels without an external DSP. In the embedded taxonomy: PIC32MX -> PIC32 family -> 32-bit MCU -> microcontroller -> embedded processor. Key features: 50 MHz / 83 DMIPS M4K core; 256KB Flash and 32KB SRAM; Peripheral Pin Select (PPS) for flexible signal routing; 10-bit ADC up to 1 Msps; Charge Time Measurement Unit (CTMU) for touch sensing; 4-wire PMP for direct LCD interface; dual I2S for stereo audio codecs; full-speed USB 2.0 device/host/OTG. Two I2C buses share with SPI muxing in PPS; 16-bit parallel PMP doubles as a graphics engine for QFSMP-LCD control panels. Architecturally, the M4K core runs a 5-stage pipeline with hardware multiply-divide, plus DSP-style SIMD instructions in the multimedia extension. The PPS peripheral remap block keeps the silicon die constant while letting the firmware relocate UART, SPI, and I2C onto almost any digital I/O pin. Internal 8 MHz RC oscillator plus PLL give the system 50 MHz from a low-cost 8 MHz crystal, and the on-chip voltage regulator simplifies single-supply designs. Typical applications: HMI touch panels with integrated audio playback; USB audio devices (headsets, USB speakers); graphics LCD controllers via PMP; low-cost DSP front-ends; industrial control with USB diagnostics. The CTMU + ADC combination is purpose-built for capacitive touch on glass overlays. Design consideration: route the USB D+/D- lines as a 90-ohm differential pair with the EPAD of the QFN tied to a continuous ground plane for thermal dissipation. At 50 MHz, four PCB layers are strongly recommended.
