PIC32MX150F128BT-I/SO Visão geral
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.

Aplicações típicas
PIC32MX150F128BT-I/SO é adequado para 6 aplicaçãos: USB Audio Peripherals, Graphical HMI with PMP Display, Capacitive Touch User Interface, Industrial Sensor Hub, Battery-Powered Data Logger, Migration from 8-bit PIC16/PIC18 Designs.
USB Audio Peripherals
The PIC32MX150F128BT-I/SO is well matched to USB audio peripherals because it integrates a full-speed USB 2.0 device controller with a dedicated PLL, two I2S/SPI modules for codec interfacing, and 32 KB of SRAM for audio buffer management. The MIPS32 M4K core at 40 MHz delivers enough throughput to manage USB isochronous endpoints, perform software volume/equalization, and feed an external DAC over I2S without dropouts. Operating from 2.3 V to 3.6 V simplifies direct Li-ion or USB-bus powered designs. The 128 KB Flash accommodates USB audio class drivers plus application firmware, while PPS allows flexible PCB routing of USB, I2S, and control buttons. Use an external 48 MHz crystal to meet USB clock accuracy.
Recomendado
Graphical HMI with PMP Display
The PIC32MX150F128BT-I/SO suits small graphical HMI panels via its Parallel Master Port (PMP), which directly drives 8-bit or 16-bit parallel LCDs and TFTs without an external controller. At 40 MHz the MIPS32 M4K core can refresh 320x240 QVGA panels over PMP while leaving headroom for capacitive touch processing and menu logic. The 128 KB Flash holds embedded GUI libraries and asset tables, and the 32 KB SRAM is enough for double-buffered framebuffer tiles. Peripheral Pin Select frees the PMP data bus to be remapped if board layout requires. Industrial -40C to +85C operation covers factory-floor and outdoor enclosures, and 2.3 V-3.6 V operation allows direct white-LED backlight driver control via PWM timers.
Recomendado
Capacitive Touch User Interface
The PIC32MX150F128BT-I/SO supports mTouch capacitive touch buttons, sliders, and proximity sensors through the on-chip 10-bit ADC and CVD peripherals, eliminating the need for an external touch controller IC. The 40 MHz MIPS core runs the Microchip mTouch library with scan times under 5 ms for typical 8-channel interfaces, allowing responsive UI feedback. The 128 KB Flash holds the touch firmware plus application logic, and PPS lets the designer route the ADC channels to any convenient PCB location. Industrial -40C to +85C operation ensures consistent touch behavior in outdoor kiosks and appliance control panels, while the SOIC-28 footprint simplifies hand-soldering for prototype iterations.
Recomendado
Industrial Sensor Hub
The PIC32MX150F128BT-I/SO acts as a small-form-factor industrial sensor hub by aggregating I2C sensor inputs (temperature, pressure, humidity) and forwarding data over UART, SPI, or USB to a host PLC or gateway. Two I2C and two UART channels allow multi-bus architectures without extra muxes, while the 4-channel DMA offloads repetitive sensor reads from the CPU. The 10-bit 1 Msps ADC can simultaneously digitize a 4-20 mA loop or a 0-10 V analog sensor signal. Industrial -40C to +85C operation and the wide 2.3 V-3.6 V supply range tolerate harsh factory-floor rails, and the SOIC-28 package is well suited to conformal-coated boards.
Recomendado
Battery-Powered Data Logger
The PIC32MX150F128BT-I/SO's sub-0.5 mA/MHz active current and multiple low-power sleep modes (down to microamp-level standby) make it suitable for battery-powered portable data loggers. The 128 KB Flash stores weeks of compressed log data with wear-leveled EEPROM emulation, while the 32 KB SRAM buffers burst sensor samples before flash write cycles. The 10-bit ADC samples at 1 Msps, capturing fast analog transients, and on-chip temperature sensing compensates for sensor drift across the -40C to +85C operating range. USB device mode enables convenient battery-charged PC-side download without an external bridge IC.
Recomendado
Migration from 8-bit PIC16/PIC18 Designs
The PIC32MX150F128BT-I/SO is the recommended first step when migrating from 8-bit PIC16F or PIC18F designs to a 32-bit architecture, because the SOIC-28 footprint, MPLAB X toolchain, and Harmony code-configurator carry over without retraining. The MIPS32 M4K core delivers roughly 30x-50x the instruction throughput of PIC18F at the same clock, so legacy firmware ports with significant speed gains. The 128 KB Flash / 32 KB SRAM envelope covers nearly all PIC18F target applications, and the same peripheral set (UART, I2C, SPI, ADC, timers) means existing driver code ports directly. The industrial -40C to +85C temperature range matches legacy PIC18F operating envelopes, simplifying qualification reuse.

Notas de projeto
The PIC32MX150F128BT-I/SO operates from a single 2.3 V to 3.6 V rail. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of each VDD pin, plus a bulk 10 uF tantalum or ceramic close to the device. The internal voltage regulator requires a 10 uF + 100 nF pair on VDDCORE (available as an internal node on most PIC32MX1xx variants) to maintain regulator stability. For USB operation, ensure the 3.3 V rail stays within +/- 0.3 V of nominal to meet USB signal-eye compliance.
Use Peripheral Pin Select (PPS) to remap UART, SPI, I2C, timers, and comparator outputs to available pins, but always cross-check the PPS mapping table in the PIC32MX1XX/2XX datasheet because not every peripheral function is available on every pin. Place the 8 MHz or 12 MHz primary crystal within 5 mm of OSC1/OSC2 with a grounded guard ring to reduce EMI coupling into the USB PLL. For USB differential pairs (D+/D-), maintain 90 ohm differential impedance with maximum 5 mm trace length and a common-mode choke if the cable is longer than 1 m.
Do not rely on the internal 8 MHz Fast RC for USB operation; it does not meet USB clock accuracy requirements. Use an external 48 MHz crystal or lock the USB PLL to the primary 8 MHz oscillator with software calibration against the USB Start-Of-Frame packet. Always set the JTAGEN fuse to disabled in production builds to free the RB13/RB15 pins for GPIO. Configure unused pins as digital outputs driven low to minimize supply current creep through floating input buffers.
