PIC32MX150F128BT-V/SS Übersicht
An MCU (microcontroller unit) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and on-chip peripherals such as ADC, timers, communication interfaces, and I/O. The PIC32 family sits above the 8-bit PIC16/PIC18 families and below the high-performance PIC32MZ/32MK families, addressing applications that need 32-bit processing headroom with low power and rich peripherals. Within the PIC32MX1xx/2xx series, the part number suffix encodes the package and grade: T = tape and reel, V = -40C to +105C operating range, and SS = 28 SSOP.
Key features include a MIPS32 M4K core running up to 40 MHz (50 MHz on selected -50I variants), Peripheral Pin Select (PPS) for flexible I/O mapping, a Parallel Master Port (PMP) for graphics interfaces, two I2S/SPI modules for audio codec interfacing, mTouch capacitive-touch support, a 1 ns high-resolution timer, and an on-chip temperature sensor. The device also integrates a 10-bit ADC, five 16-bit timers plus two 32-bit timers, DMA, and USB 2.0 full-speed on-package variants.
Architecturally, the PIC32MX150 combines a Harvard-style MIPS core with a multi-channel DMA engine, a 1.5 Msps 10-bit ADC, and analog comparators on a single die. The 128 KB Flash holds application code, while the 32 KB SRAM supports data buffers for USB and audio streams. PPS allows most digital peripherals to be remapped to any digital I/O pin, simplifying PCB routing.
Typical applications include USB audio devices, capacitive-touch human-machine interfaces, low-cost graphics modules with PMP, sensor hubs, and industrial sensor nodes. The 128 KB Flash and 32 KB SRAM are sufficient for protocols such as USB HID/CDC, basic Bluetooth HCI stacks, and small RTOS kernels.
When designing, ensure a 10 uF bulk + 0.1 uF bypass capacitor is placed within 6 mm of each VDD/VSS pair, and that traces to the 8 MHz crystal (or 40 MHz internal oscillator configuration) are kept short to minimize EMI and clock jitter.

Typische Anwendungen
PIC32MX150F128BT-V/SS ist geeignet für 6 Anwendungs: USB Audio Device, Capacitive Touch HMI, Industrial Sensor Hub, Low-Cost Graphics Module, USB HID Control Device, Battery-Powered IoT Sensor Node.
USB Audio Device
The PIC32MX150F128BT-V/SS fits USB audio because its integrated USB 2.0 full-speed controller with on-chip transceiver and two I2S/SSI modules target digital audio streaming at 16-bit/48 kHz stereo. The 128 KB Flash holds USB Audio Class 1.0 descriptors and a small RTOS kernel, while the 32 KB SRAM buffers USB isochronous packets (typically 4-8 ms of stereo audio) without dropping frames. Compared to discrete USB plus DAC solutions, this PIC32 consolidates USB protocol handling and audio sample routing on one die, reducing BOM count by 3-5 parts. Place the MCU near the USB connector with a 15 kΩ D+ pull-up to VDD and an external 48 MHz crystal to drive the USB PLL with < 0.25% frequency error.

Capacitive Touch HMI
For capacitive-touch human-machine interfaces, the PIC32MX150F128BT-V/SS supports up to 13 mTouch channels via its CTMU peripheral, with 1 ns time measurement resolution for proximity and water-tolerant touch sensing. The 128 KB Flash stores touch firmware plus a small GUI for an OLED or character LCD, while the 32 KB SRAM handles debounce buffers and gesture state. Unlike dedicated touch controllers that require a separate MCU, this part integrates touch acquisition on the same die, eliminating the I2C/SPI overhead of a two-chip solution. Route the touch electrodes as short PCB traces with no ground plane beneath them and add a 100 nF series capacitor on each CTMU channel for EMC immunity.
Empfohlen
Industrial Sensor Hub
In industrial sensor-hub applications, the PIC32MX150F128BT-V/SS combines a 10-bit 1.5 Msps ADC for analog sensor sampling, eight DMA channels for low-CPU-overhead data movement, and the V-grade -40C to +105C range for factory-floor deployments. The 128 KB Flash runs Microchip's Harmony TCP/IP Lite stack plus Modbus RTU slave firmware, while the 32 KB SRAM buffers sensor frames. Compared to a discrete MCU + ADC architecture, this PIC32 adds analog comparators and a temperature sensor on-chip, reducing board space by 30-40%. Use 4-wire SPI to external sensors at 10 MHz, and add TVS diodes on analog inputs to survive IEC 61000-4-2 ESD events.
Empfohlen
Low-Cost Graphics Module
For low-cost graphics modules driving QVGA or smaller TFT displays, the PIC32MX150F128BT-V/SS integrates a Parallel Master Port (PMP) capable of up to 25 MHz pixel clock - sufficient for 320x240@60 fps through an 8-bit PMP interface to common ILI9341 / ST7789 controllers. The 128 KB Flash fits a small GUI library plus framebuffer handling, and the 32 KB SRAM provides a partial framebuffer for block-level updates. Compared to dedicated graphics MCUs such as PIC32MZ DA, this part cuts cost by 60% while still supporting menu-driven interfaces in appliances, instruments, and IoT panels. Place 10 uF + 100 nF bypass within 5 mm of every VDD pin and route PMP data lines as 8-bit length-matched bus to the display connector.
Empfohlen
USB HID Control Device
The PIC32MX150F128BT-V/SS is well suited for USB Human Interface Devices such as custom keyboards, game controllers, and HID-based remote controls. The integrated USB 2.0 full-speed controller with on-chip pull-ups handles USB enumeration without external components, while the 128 KB Flash stores HID report descriptors and key-mapping tables. The 32 KB SRAM handles HID debounce buffers. Compared to low-end 8-bit MCUs plus an external USB controller, this PIC32 reduces BOM by 2-3 parts and simplifies USB stack maintenance. Implement VBUS sensing on a GPIO to detect cable connection, and add a ferrite bead + capacitor filter on VUSB to meet USB-IF conducted emissions limits.
Empfohlen
Battery-Powered IoT Sensor Node
For battery-powered IoT sensor nodes, the PIC32MX150F128BT-V/SS supports deep-sleep currents around 1 mA in idle and can wake via RTCC, External Interrupt, or peripherals - enabling multi-month battery life on a 2xAA cell for duty-cycled sensor reporting. The 128 KB Flash runs BLE HCI passthrough or LoRa SX1276 driver stacks, and the 32 KB SRAM buffers sensor samples between sleeps. Compared to higher-end Cortex-M0+ parts, this PIC32 trades off a slightly higher active current (~20 mA at 40 MHz) for richer USB and PMP connectivity. Use a 32.768 kHz watch crystal for RTCC, and add a Schottky diode + 100 uF bulk for backup capacitor behavior on power switching.

Wichtigste Unterscheidungsmerkmale
- V-grade extended-industrial temperature range with tape-and-reel packaging (vs. PIC32MX150F128B-I/SS)
- Balanced Flash/RAM ratio with on-chip USB (vs. PIC32MX130F256B-V/SS)
- Stable 40 MHz specification versus higher-current 50 MHz option (vs. PIC32MX150F128B-50I/SS)
Designhinweise
Place a 10 uF bulk + 100 nF high-frequency bypass within 5 mm of every VDD/VSS pair on the PIC32MX150F128BT-V/SS. According to Microchip's PIC32 hardware design checklist, the VDD rails (multiple pins on 28-SSOP) must each see a local decoupling cap; sharing one cap across multiple VDD pins creates a 50-150 mV droop during USB peak currents (up to 100 mA in host mode). Use X5R/X7R ceramics rated 6.3 V or higher to retain 50%+ capacitance at 3.3 V bias.
Route the crystal traces (OSC1/OSC2, pins 9-10) as a 5-10 mm guarded pair with no other signal traces crossing within 5 mm. According to Microchip's oscillator design application note, trace capacitance above 5 pF on either side can detune the crystal by 5-15 ppm, causing USB clock drift and audio sample-rate errors. Place a ground guard ring around the crystal + load capacitors and keep the oscillator away from high-current switching nodes (inductor, MOSFET, USB data lines).
Estimated: at maximum active CPU load (40 MHz, USB + I2S active, peripherals on), the PIC32MX150F128BT-V/SS draws approximately 20-25 mA from VDD, dissipating 66-83 mW. With a typical 28-SSOP theta_JA of 80-100 C/W, junction temperature rise is 5-8 C above ambient, well within the 105 C maximum. The V-grade -40C to +105C specification provides adequate headroom for sealed industrial enclosures with internal ambient up to 85 C.
Do NOT omit the 100 nF capacitor on the VCAP pin (if exposed on package variant) - this internal voltage regulator output requires 1 uF + 100 nF for stable core operation. According to the Microchip errata for PIC32MX1xx/3xx, missing VCAP bulk capacitance causes intermittent resets and brown-out events. Also, configure unused I/O pins as digital outputs (not inputs) to avoid parasitic current draw of 1-5 uA per pin across 21 I/Os.
Compliance-Informationen
RoHS compliant and lead-free per Microchip product page. Not AEC-Q100 qualified - choose AEC-Q100 variants such as PIC32MX150F128BT-V/SS automotive-suffix parts if automotive PPAP compliance is required. MSL-1 rated per JEDEC J-STD-020.
