PIC32MX150F128B-V/SS Обзор
A 32-bit microcontroller (MCU) is a programmable system-on-chip that integrates a CPU core, Flash program memory, SRAM, and a rich set of peripherals on a single die. Within the broader taxonomy, PIC32MX devices sit in the microcontroller -> embedded controller -> semiconductor hierarchy. The MIPS M4K core supports the MIPS32 instruction architecture, providing 32-bit datapath performance while remaining code-compatible with the broader PIC32 ecosystem. This PIC32MX150/170/1XX family targets cost-sensitive embedded designs needing USB, audio, and graphics interfaces.
Key features 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 support for mTouch capacitive touch buttons and sliders. The integrated Charge Time Measurement Unit (CTMU) provides 1 ns high-resolution time measurement, while an on-chip temperature sensor simplifies thermal monitoring without external components. Five general-purpose 16-bit timers and a 10-bit ADC round out the analog and timing peripherals.
Architecturally, the M4K core is a 5-stage pipeline RISC processor with hardware multiply/divide, delivering 1.56 DMIPS/MHz. The 128 KB Flash is organized as 128K x 8 with ECC support, and 32 KB SRAM provides ample workspace for protocol stacks and audio buffers. PPS is particularly valuable because it allows digital peripheral pins to be remapped in software, simplifying PCB layout when signals would otherwise need to cross.
Typical applications include USB audio peripherals, low-cost graphics HMI with PMP-driven LCDs, capacitive touch key panels, industrial control with mTouch, and automotive body controllers benefiting from the extended -40°C to +105°C grade. The device is well-suited to bridge products transitioning from PIC16/PIC24 designs to 32-bit performance.
When using this part, ensure the 32 kHz crystal and PLL configuration follow the datasheet's oscillator tuning procedure to meet USB Full-Speed timing. JTAG/ICSP pads must remain accessible for in-circuit programming if the application does not dedicate them to other functions.

Типичное применение
PIC32MX150F128B-V/SS подходит для 6 применениеs: USB Audio Peripherals, mTouch Capacitive Touch HMI, Graphics HMI with Parallel Master Port, Industrial Control and Automation, Automotive Body Controllers, Low-Cost Embedded Gateways.
USB Audio Peripherals
The PIC32MX150F128B-V/SS is well-suited to USB audio peripherals like USB speakers, headsets, and DAC interfaces. Its 40 MHz MIPS32 M4K core delivers sufficient processing bandwidth for USB Full-Speed isochronous endpoints and audio sample-rate conversion, while the integrated on-chip USB transceiver and pull-up resistor eliminate external USB components. The 32 KB SRAM can buffer 16-bit stereo audio at 48 kHz with comfortable headroom for packet scheduling, and the two I2S modules provide direct digital audio interface to external DACs and codecs. The -40 to +105 °C automotive temperature grade also suits car-infotainment audio accessories operating in hot cabin environments.

mTouch Capacitive Touch HMI
With native mTouch support and the integrated Charge Time Measurement Unit (CTMU), the PIC32MX150F128B-V/SS is a strong choice for capacitive touch key panels and slider interfaces. The CTMU provides 1 ns time-resolution charge measurement, enabling reliable touch detection through glass and plastic overlays without an external touch controller IC. The 21 I/O pins support up to 21 touch channels directly, and PPS routing lets the layout engineer place sensor traces conveniently. The 128 KB Flash is large enough to host Microchip's mTouch library plus user application logic, while 32 KB SRAM handles the scanning state without burdening the CPU.

Graphics HMI with Parallel Master Port
The PIC32MX150F128B-V/SS integrates a Parallel Master Port (PMP) that can directly drive small TFT LCD displays up to 8-bit parallel in 8080/6800 mode, making it a good fit for low-cost graphics HMI panels. The 40 MHz CPU core is adequate for simple GUIs and menu rendering, while PPS allows the PMP data and control signals to be remapped for layout flexibility. With 128 KB Flash available, designers can store multiple fonts and bitmaps in compressed form and decompress to a small frame buffer. The 32 KB SRAM is sufficient for offscreen drawing and double-buffered animations on QVGA displays.

Industrial Control and Automation
The -40 to +105 °C automotive temperature grade of the PIC32MX150F128B-V/SS extends its usefulness into harsh factory and process-control environments where commercial-grade parts would fail. The 10-bit ADC handles analog sensor readings from thermocouples, pressure transducers, and 4-20 mA loops when paired with a current-sense amplifier. Multiple 16-bit timers can drive PWM outputs for motor speed control, soft-start, and synchronous rectification. The PIC32MX1XX/2XX ecosystem includes certified TCP/IP stacks and CAN libraries, simplifying industrial networking and motor-control firmware development.
Рекомендуется
Automotive Body Controllers
Automotive body controllers for lighting, HVAC, and door modules benefit from the PIC32MX150F128B-V/SS automotive-grade -V temperature suffix. The 40 MHz MIPS32 M4K core handles CAN stack, LIN master, and body-control logic concurrently, and PPS lets the designer route CAN, LIN, and PWM signals to convenient PCB locations. On-chip temperature sensing simplifies self-diagnostics, while the CTMU can be repurposed for key-press or liquid-level measurement. The 128 KB Flash is sufficient for a Vector AUTOSAR-lite or OEM-specific body controller firmware, and Microchip's MPLAB X IDE plus MPLAB Harmony framework accelerate automotive firmware certification.
Рекомендуется
Low-Cost Embedded Gateways
USB host/device capability plus UART, SPI, and I2C peripherals position the PIC32MX150F128B-V/SS as a compact protocol-translation gateway. Typical designs use the MCU to bridge a USB host port to SPI sensors, or to bridge a UART-controlled wireless module to an I2C peripheral cluster. The 128 KB Flash accommodates a small TCP/IP or USB stack plus the bridging firmware, while the 32 KB SRAM is enough for packet buffers in low-throughput bridges. The -40 to +105 °C automotive grade broadens applicability to vehicle-mounted gateways in cabin or under-hood environments.

Заметки по проектированию
The PIC32MX150F128B-V/SS has two VDD/VSS pairs (pins 7/8 and 18/19) plus additional VSS pins 13. Decouple both VDD pairs with 100 nF ceramic capacitors placed as close to the respective pins as possible, with a bulk 10 µF tantalum or aluminum-polymer capacitor nearby on the supply rail. For USB applications, route the D+ and D- traces with 90 Ω differential impedance and add ferrite beads if the design has noisy switching nodes near the USB connector. Brown-out reset (BOR) should be enabled during the LDO module configuration.
The 28-pin SSOP package has 0.65 mm pitch which is hand-solderable but tight for rework; reserve at least 8 mil traces and 8 mil spacing on PCB escape routing around the device. Use a 4-layer PCB with a continuous ground plane beneath the device for best EMI and signal integrity. The ICSP/PGED1/PGEC1 pins (pins 9 and 10) must remain accessible to a programming header or test pad - do not dedicate them to other peripherals if field updates are required. JTAG pins 25-28 are alternate functions and can be released to general I/O via the JTAGEN bit in CFGCON after programming.
Do not confuse the -V/SS suffix with the -V/SO or other package codes - the -SS denotes SSOP only. When migrating firmware between the -V/SS and -50I/SS variants, the clock configuration bits and peripheral library headers must be updated, although user code is otherwise source-compatible. Watch for PPS remap conflicts: when the USB D+/D- pins (20, 21) are used in PPS mode they cannot simultaneously act as GPIO RB8/RB9, so plan pin allocation before code freeze. PPS input pin groups are limited and the datasheet pin selection tables (section 11.0 I/O Ports) must be consulted to ensure a signal can be mapped to the desired physical pin.
Estimated: At maximum 40 MHz active current of <0.5 mA/MHz, the MCU core draws roughly 20 mA. Combined with I/O pin currents (sourced up to 15 mA per pin in groups), worst-case device power dissipation at 3.6 V is approximately 75 mW, well below SSOP-28 thermal limits. In typical USB audio applications running at 30% duty cycle, total power is around 30 mW, allowing PCB-only thermal management. No external heatsink is required for normal operation, but the device should be derated to 70 mA total I/O current per the absolute maximum ratings.
