PIC32MX150F128CT-50I/TL 概要
A PIC32MX series microcontroller is a 32-bit MCU based on the MIPS32 M4K core, designed by Microchip for embedded applications requiring higher performance than 16-bit PIC microcontrollers. Within the broader system hierarchy, PIC32MX devices sit between PIC24F (16-bit) and PIC32MK/MZ (32-bit high-performance) families, falling under the umbrella of MIPS-based 32-bit microcontrollers and the wider category of embedded microcontrollers. The PIC32MX1XX/2XX 28/36/44-pin family specifically targets cost-sensitive applications requiring USB, advanced peripherals, and graphics/audio interfaces. The M4K core executes most instructions in a single cycle, giving the 50MHz part 50 Dhrystone MIPS of performance.
Key features of the PIC32MX150F128CT-50I/TL include up to 25 I/O pins, two UART modules, two I2C modules, two SPI modules, a Parallel Master Port (PMP), 10-bit ADC with up to 12 channels, 5 PWM, Peripheral Pin Select (PPS) functionality for flexible pin assignment, hardware DMA with up to 4 channels, and JTAG programming/debug interface. The exposed pad on the VTLA package improves thermal dissipation for higher-current applications.
Architecturally, the device integrates a Harvard architecture with separate instruction and data paths, configurable interrupt controller supporting up to 64 interrupt sources with 7 priority levels, and multiple low-power sleep modes (idle, sleep, deep-sleep) for power-constrained applications. The integrated USB 2.0 full-speed controller supports both device and host/OTG modes when paired with proper external components.
Typical applications include industrial automation (PLCs, motor control interfaces), consumer audio/graphics interfaces with USB connectivity, USB peripherals such as mice, keyboards, and Human Interface Devices (HIDs), portable data loggers, sensor hubs, and low-cost graphics display controllers. The combination of 128KB Flash, 32KB RAM, USB, and PMP makes it suitable for applications traditionally served by more expensive Cortex-M0+ devices.
A key design consideration is power supply decoupling. Place a 0.1uF ceramic bypass capacitor as close as possible to each VDD/VDDCORE pin and a bulk 10uF tantalum or ceramic capacitor near the package to ensure stable operation. Use the exposed pad as a thermal dissipation path by soldering it to a copper pour on the PCB.

Industrial Control Interfaces
The PIC32MX150F128CT-50I/TL fits industrial control interfaces such as PLCs, motor control front-ends, and HMI panels that require deterministic 32-bit performance and industrial temperature tolerance. The 50 MHz MIPS32 M4K core executes control loops in microseconds, the dual UART enables RS-232/RS-485 communications to other controllers, and the industrial -40C to +85C rating supports harsh factory environments. The integrated 10-bit ADC (number of channels) reads sensor inputs such as temperature, pressure, and current. With Peripheral Pin Select, you can route UART, SPI, and I2C pins to PCB layout-optimal positions without redesign.
おすすめ
Portable Data Loggers
The PIC32MX150F128CT-50I/TL is well-suited for portable battery-powered data loggers that need 32-bit performance and integrated peripherals. With 50 MHz performance, the MCU can sample multiple sensor channels at high rates, run compression algorithms, and write to external Flash or SD cards via SPI. The 128KB Flash stores logger firmware and embedded file system support, while 32KB SRAM provides buffer space for time-stamped sensor data. Low-power sleep and idle modes minimize battery drain during idle periods. The 2.3V to 3.6V operating range directly supports 2xAA or lithium battery chemistries.

The Parallel Master Port (PMP) drives 8-bit parallel TFT/OLED displays at high refresh rates, while 50 MHz MIPS performance renders simple graphics, text, and menus smoothly. The Peripheral Pin Select feature allows flexible routing of SPI touch controllers, I2C sensors, and UART communication pins. The 128KB Flash accommodates graphics libraries, fonts, and localized UI strings, while 32KB SRAM provides display framebuffer or render buffer.
おすすめ
Sensor Hubs and IoT Edge Nodes
The PIC32MX150F128CT-50I/TL is well-suited for sensor hubs and IoT edge nodes that aggregate data from multiple I2C/SPI sensors, perform local processing, and forward results over USB, SPI, or UART. The 50 MHz core runs sensor fusion algorithms and local analytics, while two I2C and two SPI interfaces connect to multiple sensors concurrently. The 128KB Flash stores IoT protocol stacks (MQTT-SN, Lwm2m) or custom edge processing logic, while 32KB SRAM supports data buffering. The integrated USB enables easy PC connection for configuration and firmware updates. Low-power sleep modes extend battery life in intermittently-operating IoT deployments.

設計ノート
Decoupling strategy: Place a 0.1uF ceramic bypass capacitor within 2mm of each VDD pin (pins 9 and 29) and a single 10uF bulk tantalum or ceramic capacitor near the package. According to Microchip's PIC32MX1XX/2XX family design guide, inadequate decoupling causes intermittent USB enumeration failures and ADC measurement noise. For USB applications, place 0.01uF capacitors as close as possible to the VUSB and VDD3V pins if [USB] are present in this layout.
Exposed thermal pad handling: The 36-pin VTLA package includes an exposed pad (pin 36) on the underside that should be connected to a copper ground pour on the PCB. According to the manufacturer datasheet, soldering the exposed pad improves thermal dissipation and is required for reliable operation at high CPU loads. For best results, use multiple thermal vias in the exposed pad to distribute heat to inner PCB copper layers. Without the pad soldered, junction temperature can rise 15-20C at full 50 MHz load.
Crystal oscillator placement: If using an external crystal for the primary oscillator, place the crystal as close as possible to the OSC1 (pin 30) and OSC2 (pin 31) pins. Keep crystal traces short, symmetric, and surrounded by a ground pour to minimize EMI. According to Microchip application note AN588, crystal load capacitors (typically 10-22 pF) should be placed on the same PCB side as the crystal, with short traces to the OSC pins. Avoid routing high-speed digital signals (USB, SPI) near the crystal traces.
ICSP programming: The PIC32MX150F128CT-50I/TL uses RB6 (PGEC2, pin 7) and RB7 (PGED2, pin 8) for In-Circuit Serial Programming. Do not place low-impedance loads on these pins that would interfere with programming. According to Microchip programming specifications, add 4.7kOhm pull-ups on MCLR (pin 32) to VDD for proper reset behavior during programming and normal operation. For JTAG, TMS, TDI, TDO, and TCK are available on dedicated pins per the datasheet.
USB trace routing: The USB D+ (pin 34) and D- (pin 35) lines require matched 90-ohm differential impedance routing. According to USB 2.0 specifications, keep the differential pair traces short (under 50mm ideally), maintain constant spacing for 90-ohm differential impedance, and avoid right-angle bends. Place the 15kOhm pull-down resistor on D- if operating in device mode. Series ferrite beads on VUSB can improve EMI compliance.
