MPN: PIC32MX150F128BT-50I/SS ✓ פעילPIC32MX150F128BT-50I/SS סקירה
A 32-bit microcontroller (MCU) is a single-chip computer integrating a 32-bit processor core, program and data memory, and programmable peripherals. Within the system hierarchy, the PIC32MX150F128B belongs to the PIC32MX family -> 32-bit MCU family -> microcontroller -> embedded processor -> semiconductor. Compared to 8-bit PIC MCUs, the MIPS32 M4K core offers up to 1.56 DMIPS/MHz, suitable for DSP and graphics workloads where 8-bit cores cannot keep pace.
Key features include 50 MHz max CPU speed, 128 KB Flash program memory organized as 128K x 8, 32 KB SRAM, USB 2.0 full-speed Device/Host/OTG support, 10-bit 1 Msps ADC with up to 13 analog inputs, four I2C, five UART, two I2S/SPI, and PMP for graphics LCDs. A real-time clock and calendar (RTCC) with backup power input is integrated, plus five 16-bit timers and a 32-bit core timer for precise scheduling.
Architecturally, the device uses a Harvard bus with separate Flash and RAM paths, M4K pipelined core with single-cycle multiply, and Peripheral Pin Select remapping that allows most digital peripherals to be routed to any remappable GPIO pin at runtime. This eliminates the PCB redesign cycle when a peripheral is moved. Internal 8 MHz FRC and PLL support 4x multiplication to reach 50 MHz system clock without external oscillator cost.
Typical applications include USB peripherals (HID, CDC, audio class), small TFT graphics HMI panels using PMP, audio codec interfaces via I2S, capacitive touch button panels, low-cost industrial sensor hubs, and consumer appliances requiring USB connectivity with modest computational headroom. The integrated USB PHY makes the PIC32MX150F128BT particularly attractive for low-BOM-count designs.
When designing with this MCU, allocate decoupling capacitors (100 nF + 10 uF) on each VDD/AVDD pair within 3 mm of the pins, and follow Microchip's application note AN588 for USB board layout to maintain 90-ohm differential impedance. The ICSP programming pins must be brought out for in-circuit programming and debugging; consult MPLAB X IDE for pin allocator settings.

יישומים טיפוסיים
PIC32MX150F128BT-50I/SS מתאים עבור 7 יישוםs: USB HID Peripheral Devices, Small TFT Graphics HMI, USB Audio Codec Interface, Industrial Sensor Hub, Capacitive Touch Button Panel, Consumer Appliance Control, Low-Cost Data Acquisition Module.
USB HID Peripheral Devices
The PIC32MX150F128BT-50I/SS's integrated USB 2.0 full-speed controller with on-chip PHY makes it ideal for USB HID-class peripherals such as keyboards, mice, game controllers, and custom input devices. The 50 MHz MIPS32 M4K core provides sufficient throughput for USB polling at 1 kHz with comfortable headroom for button debouncing, LED control, and protocol handling. The 128 KB Flash accommodates full HID report descriptors, vendor-specific report maps, and bootloader firmware. Two I2S/SPI modules can drive addressable RGB feedback LEDs while the USB stack runs concurrently. Power consumption stays below 25 mA during full-speed USB traffic, well within USB 2.0 bus-powered device limits.
מומלץ
Small TFT Graphics HMI
The integrated Parallel Master Port (PMP) peripheral drives small TFT LCD panels up to 480x272 (WQVGA) directly from the PIC32MX150F128BT-50I/SS without an external graphics controller. PMP supports 8-bit or 16-bit parallel interface with dedicated control signals, freeing CPU cycles for UI logic. The 50 MHz core renders fonts and simple shapes fast enough for responsive touch UI at 30 fps. mTouch capacitive touch sensing inputs pair naturally with PMP for integrated touch HMI panels. Designers should follow Microchip AN1428 for PMP timing on 3.3V-only panels to avoid bus contention.
מומלץ
USB Audio Codec Interface
The two I2S/SPI modules on the PIC32MX150F128BT-50I/SS interface directly to external 24-bit audio codecs such as the Microchip LAN8740A-class parts or third-party DACs like the TI PCM5102A. USB Audio Class 1.0 streams at 48 kHz/16-bit fit comfortably within the 12 Mbps USB full-speed envelope. The 32 KB SRAM holds audio sample buffers plus USB endpoint descriptors without external memory expansion. Active current under 25 mA enables bus-powered USB headphone designs where battery life and clean analog supply are critical. Use the on-chip temperature sensor for thermal foldback of the headphone output stage.
מומלץ
Industrial Sensor Hub
The PIC32MX150F128BT-50I/SS's industrial temperature range (-40C to +85C), five UART interfaces, four I2C, and 10-bit ADC make it a strong choice for industrial sensor aggregation gateways. The 50 MHz core aggregates up to four sensor buses concurrently while exposing USB or RS-485 to a higher-level controller. The RTCC with backup power maintains time-stamping during power-down for predictive maintenance data logging. Sub-0.5 mA/MHz active consumption allows solar/battery-powered remote sensors, and the PMP can drive a small status display locally.
מומלץ
Capacitive Touch Button Panel
The PIC32MX150F128BT-50I/SS supports mTouch capacitive touch sensing through the on-chip CTMU peripheral, enabling up to 13 touch buttons or a slider without external touch ICs. Combined with PPS, touch channels can be remapped at runtime to any available GPIO for flexible PCB layout. The 1 ns high-resolution time measurement module provides accurate touch acquisition timing for reliable proximity detection through glass or plastic overlays. The 50 MHz clock ensures sub-10 ms touch response latency. A small 28-SSOP footprint fits behind glass-fronted appliances easily.
מומלץ
Consumer Appliance Control
The PIC32MX150F128BT-50I/SS's combination of USB device mode, multiple UART interfaces, PMP graphics capability, and capacitive touch support fits consumer appliances like coffee machines, microwave ovens, and smart thermostats. The 128 KB Flash holds a USB firmware-upgrade bootloader plus the application, while 32 KB SRAM supports small graphics frame buffers. The integrated RTCC drives scheduled appliance functions across power cycles, and the on-chip temperature sensor can monitor internal ambient for safety shutdown. -40C to +85C range survives appliance environment extremes.
מומלץ
Low-Cost Data Acquisition Module
The 10-bit 1 Msps ADC with up to 13 input channels, combined with 32 KB SRAM for sample buffering, makes the PIC32MX150F128BT-50I/SS well-suited to compact USB-based data acquisition modules. Designers can stream 13 channels at 10 kHz each to a host PC via USB, sufficient for vibration analysis, multi-thermocouple monitoring, or low-bandwidth instrumentation. PPS remapping allows the ADC-trigger timer to be routed to any pin for external synchronization. 3.3V single-supply operation simplifies analog front-end design.

הערות תכנון
Place a 100 nF decoupling capacitor within 3 mm of each VDD pin (pins 15 and 27) and another on AVDD (pin 16). Add a bulk 10 uF ceramic or tantalum capacitor near the IC for transient load handling, especially when the USB controller toggles. The VUSB3V3 pin requires a 100 nF + 4.7 uF capacitor per Microchip AN588 to stabilize the internal USB 3.3V regulator. Avoid routing noisy digital lines near the AVDD/AVSS pair.
Route the USB D+ and D- traces as a 90-ohm differential pair with continuous reference plane on the layer below, matching lengths within 150 mil. Keep the pair away from clock traces and switching signals. Per Microchip AN588, place the VBUS sense resistor near the connector and avoid stubs. Use a common-mode choke on D+/D- if operating in noisy industrial environments to pass EN 55022 Class B EMI testing.
Do not leave MCLR floating - always tie it to VDD through a 10 kohm pull-up resistor, with a 100 nF capacitor to ground if MCLR is also used for in-circuit programming. Configure unused I/O pins as outputs driven low to minimize current leakage. The ICSP pins (PGECx/PGEDx) must be accessible for production programming; do not share them with critical peripherals without proper isolation. Verify the Configuration Words in code for proper WDT and oscillator settings before first power-up.
The 28-SSOP package has typical theta_JA of approximately 80 C/W when mounted on a standard 4-layer JEDEC test board. At full USB + peripheral activity, worst-case active current is around 25 mA from 3.3V, dissipating approximately 83 mW. Junction temperature rise above ambient is roughly 6.6 C, well within the 125 C maximum. For industrial deployments at +85 C ambient, internal die temperature stays around 91.6 C with comfortable margin for the -40C to +85C operating range.
