PIC32MX150F128B-50I/SS

PIC32MX150F128B-50I/SS - 50MHz 32-bit MCU 128KB Flash | Microchip

The Microchip PIC32MX150F128B-50I/SS is a 32-bit MIPS32 M4K RISC microcontroller running at up to 50 MHz with 128 KB Flash and 32 KB SRAM in a 28-pin SSOP package. It belongs to the PIC32MX1xx/2xx 28/36/44-pin family and integrates audio/graphics interfaces, USB, advanced analog peripherals, and on-chip mTouch capacitive-touch support. A 32-bit microcontroller (MCU) is a single-chip computer that integrates a 32-bit CPU core, Flash program memory, SRAM data memory, and a rich peripheral set (ADC, timers, communication controllers, GPIO) into one package. MCUs belong to the broader hierarchy of microcontrollers -> embedded processors -> semiconductors, and 32-bit MCUs are typically chosen when 8-bit or 16-bit devices lack the performance, address space, or peripheral mix required by the application. Key specifications include a 50 MHz maximum CPU clock, 1.56 DMIPS/MHz performance, sub-0.5 mA/MHz active current, a 10-bit 1 Msps ADC with up to 28 channels, two I2S/SPI modules, USB 2.0 full-speed device/host/OTG, a Parallel Master Port (PMP), and Peripheral Pin Select (PPS) for flexible signal routing. The Charge Time Measurement Unit (CTMU) supports mTouch capacitive touch buttons/sliders and provides 1 ns high-resolution time measurement. Architecturally, the device uses a Harvard-style MIPS32 M4K core with hardware multiply/divide, a 5-stage pipeline, and tightly-coupled prefetch cache to sustain 1.56 DMIPS/MHz at 50 MHz. The wide peripheral integration reduces external component count and PCB area, while the 2.3-3.6 V supply range supports both 3.3 V and battery-powered designs. Typical applications include consumer electronics with USB connectivity, industrial control with capacitive touch HMIs, low-cost audio playback using I2S codecs, USB graphics terminals using PMP-driven LCDs, sensor hubs, and small-form-factor IoT endpoints that need more headroom than 8-bit MCUs but lower cost than Cortex-M4 parts. Designers should note that the 28-pin SSOP variant limits available I/O compared to 36/44-pin cousins, so pin allocation matters; PPS allows remapping most digital peripherals to different pins, simplifying PCB layout. Decoupling, ICSP programming header placement, and VDD/VSS pin pairing per the datasheet layout guidelines are critical for noise-free operation.

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 - 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.

The single-cycle multiply hardware divider needs HW multiplier consume less than 0.5 mA/MHz for low-power embedded designs. 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.

PIC32MX150F128D-50I/TL

PIC32MX150F128D-50I/TL - 50MHz 32-bit MCU 128KB Flash | Microchip

The Microchip Technology PIC32MX150F128D-50I/TL is a 32-bit MIPS M4K microcontroller running at 50 MHz with 128 KB of Flash program memory and 32 KB of SRAM, housed in a 44-pin VTLA (6x6 mm) surface-mount package. 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. The VTLA package has an exposed thermal pad that must be soldered to the ground plane for mechanical stability and thermal dissipation.

PIC32MX150F128D-I/ML

PIC32MX150F128D-I/ML - 32-bit MCU 128KB Flash 32KB RAM 44-QFN | Microchip

The Microchip Technology PIC32MX150F128D-I/ML is a 32-bit MIPS M4K RISC microcontroller with 128 KB Flash, 32 KB SRAM, and USB 2.0 full-speed support, housed in a 44-pin QFN (ML) 8x8 mm package. It runs at up to 40 MHz (industrial grade, -40C to +85C) with sub-0.5 mA/MHz active current, and integrates Peripheral Pin Select (PPS), a Parallel Master Port (PMP) for graphics interfaces, two I2S/SPI modules for codec connectivity, and a Charge Time Measurement Unit (CTMU) supporting mTouch capacitive touch and 1 ns high-resolution time measurement. 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. Key features of the PIC32MX150F128D-I/ML include five 16-bit timers/counters, two I2C ports, two UART ports, two SPI/I2S ports, a 10-bit 1 Msps ADC with up to 28 analog inputs, an on-chip temperature sensor, a 5-bit DAC, and 34 digital I/O pins. 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.

It operates from a 2.3 V to 3.6 V supply, integrates 21 general-purpose I/O pins, and consumes less than 0.5 mA/MHz in active mode for energy-efficient embedded designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (SRAM), and a rich set of peripherals. The PIC32MX1XX/2XX family specifically targets cost-sensitive 32-bit applications where MIPS performance, USB connectivity, and audio/graphics peripherals are required. It sits within the broader hierarchy: microcontroller -> embedded processor -> semiconductor, competing directly with ARM Cortex-M0/M3 based MCUs from STMicroelectronics and NXP. Key features include two I2S/SPI modules for codec and serial audio interfaces, a Parallel Master Port (PMP) for graphics and external memory, Peripheral Pin Select (PPS) for flexible signal routing, a 10-bit 1 Msps ADC with up to 13 channels, and a Charge Time Measurement Unit (CTMU) supporting mTouch capacitive touch and high-resolution 1 ns time measurement. The device also integrates full-speed USB 2.0 (device/host/OTG), five 16-bit timers, two UART/I2C/SPI peripherals, and an on-chip temperature sensor for thermal management. Architecturally, the PIC32MX150F128D uses a Harvard-style 5-stage pipeline M4K core with single-cycle multiply and hardware divide, achieving 1.56 DMIPS/MHz. The Flash controller supports pre-fetch buffering for zero-wait-state execution up to 40 MHz, while the integrated DMA controller offloads data movement between peripherals and memory. This combination delivers deterministic real-time response suitable for USB audio, control panels, and graphics HMI applications. Typical applications include USB audio DAC interfaces, low-cost graphics HMIs with PMP-driven LCDs, capacitive touch user interfaces, industrial sensor hubs with USB connectivity, consumer medical devices, and educational development platforms. Its combination of USB, audio I2S, and graphics PMP makes it well suited for multimedia-rich embedded products. When designing with this MCU, allocate the 44-pin budget carefully: the USB pins require external 48 MHz clock or crystal and 27% accuracy internal PLL, and PPS reassignment must respect peripheral availability per pin. Use MPLAB Harmony or MCC for code generation to avoid timing errors in USB enumeration.
