PIC32MX150F256LT-V/PF Visão geral
A 32-bit microcontroller is an integrated circuit that combines a 32-bit processor core, volatile and non-volatile memory, and a programmable set of peripherals into a single chip. Within the embedded system hierarchy, a microcontroller sits below a microprocessor/MPU and above a DSP: it is a self-contained computing subsystem optimized for deterministic control tasks. The PIC32MX1xx/2xx family specifically occupies the cost-optimized, low-power tier of Microchip's PIC32 portfolio, providing higher code density and richer peripherals than 8/16-bit PIC MCUs at competitive prices.
Key features include two I2S and four SPI modules for codec and serial communication, Peripheral Pin Select (PPS) for flexible pin assignment, a Parallel Master Port (PMP) with dual read/write buffers for graphics interfaces, plus CTMU for capacitive touch. The PIC32MX150F256LT-V/PF also integrates a 10-bit 1 Msps ADC with up to 28 input channels, USB 2.0 Full-Speed Device/Host/OTG, two I2C modules, five 16-bit timers, and a wide 2.3V to 3.6V operating voltage range. AEC-Q100 qualification plus the -40C to +105C (V-grade) operating range make it suitable for under-hood automotive and industrial environments.
Typical applications include automotive infotainment/HMI, industrial control HMI panels, USB peripherals, low-cost graphics displays, and consumer audio products. With 85 user I/O available, designers have flexibility to map simultaneous LCD, touch, USB, and communication interfaces on the same board.
When designing with this device, allocate Vdd/Vss pin pairs with solid ground returns and follow Microchip application note AN833 for USB layout. The PPS feature allows remapping of digital peripherals but does not cover analog functions, so analog pin selection requires careful planning up-front.

Aplicações típicas
PIC32MX150F256LT-V/PF é adequado para 6 aplicaçãos: Automotive Infotainment HMI, Industrial Control HMI Panel, USB Peripherals and HID Devices, Low-Cost Graphics Display Module, Consumer Audio with I2S Codec, Home Appliance Control Board.
Automotive Infotainment HMI
The PIC32MX150F256LT-V/PF fits automotive infotainment HMI because of its AEC-Q100 qualification, -40C to +105C operating range, 256 KB Flash for graphics asset storage, and the Parallel Master Port with dual read/write buffers that streams data to TFT LCDs without CPU intervention. The 85 user I/O plus PPS allow concurrent touch (via CTMU), display, USB, and CAN-software-stack connectivity on the same board. Compared to higher-end MPUs, the PIC32MX150F256LT-V/PF delivers enough performance for menu rendering and audio playback while keeping BOM cost low. Designers typically pair it with the PIC32MX150F256LT-V/PF for the main MCU and a PIC16F microcontroller for keypad scanning; a 3.3V LDO (e.g., MCP1700) supplies both.
Recomendado
Industrial Control HMI Panel
The PIC32MX150F256LT-V/PF is well suited to industrial HMI panels with TFT displays and capacitive touch because of its 50 MHz MIPS32 M4K core (83 DMIPS), 32 KB SRAM for graphics frame buffering, 4 SPI modules for display and external peripherals, and CTMU for capacitive touch sensing. The PMP interface supports direct 8/16-bit bus connection to common TFT controllers without an external bridge IC, reducing BOM and PCB area. AEC-Q100 V-grade screening gives the part extra margin against the +85C typical industrial enclosure temperatures and ESD events. Recommended companion ICs include the MCP2200 USB-UART bridge for PC connectivity and the MCP2515 CAN controller for fieldbus.
Recomendado
USB Peripherals and HID Devices
The PIC32MX150F256LT-V/PF integrates USB 2.0 Full-Speed Device/Host/OTG on-chip, enabling cost-effective USB peripherals (HID, CDC, mass storage, audio class) without an external PHY. The 256 KB Flash accommodates USB stacks (Microchip MLA or Harmony) plus application code, and the 32 KB SRAM is sufficient for USB descriptor buffers and class drivers. The 50 MHz MIPS32 M4K core sustains USB 1 Ms polling plus application data processing simultaneously. Compared to lower-end 8-bit PIC MCUs, the PIC32MX150F256LT-V/PF delivers 30x the performance for the same price tier. Pair it with an MCP2221A USB-UART/I2C bridge or use it as a standalone USB device controller.
Recomendado
Low-Cost Graphics Display Module
The PIC32MX150F256LT-V/PF drives low-cost color TFT displays directly through its Parallel Master Port (PMP) with dual read/write buffers, supporting 8-bit and 16-bit bus widths at up to 25 MHz pixel clock. The 256 KB Flash stores multilingual fonts and bitmap assets, while 32 KB SRAM holds the active frame buffer for small QVGA/WQVGA panels. PPS allows flexible routing of display control signals (RD, WR, RS, CS) to free up pins for touch sensing. For larger VGA panels, consider the PIC32MX170F256L with its 64 KB SRAM. A typical BOM includes the PIC32MX150F256LT-V/PF, an MCP1700 3.3V LDO, and an SPI NOR flash (SST26VF016B) for asset storage.
Recomendado
Consumer Audio with I2S Codec
The PIC32MX150F256LT-V/PF supports two I2S interfaces plus four SPI modules, making it a good host for low-cost audio streaming designs (Bluetooth speakers, sound bars, intercoms). The I2S module can directly interface with PCM/I2S codecs such as the Texas Instruments TLV320AIC3254 or the Cirrus Logic CS4344, while the second I2S handles S/PDIF or a second channel. 50 MHz CPU clock provides ample margin for audio DSP (basic EQ, sample rate conversion) while driving the I2S DMA. AEC-Q100 V-grade plus -40C to +105C supports in-vehicle and outdoor consumer enclosures. Pair with a TPA2006 Class-D amplifier for compact audio output.
Recomendado
Home Appliance Control Board
The PIC32MX150F256LT-V/PF delivers the right balance of cost, performance, and AEC-Q100 V-grade reliability for home appliance control boards (washing machines, dishwashers, ovens, refrigerators). Its 50 MHz core runs sensor sampling, motor-control loops, and user interface simultaneously. The 10-bit 1 Msps ADC reads multiple temperature, pressure, and current sensors; five 16-bit timers drive triac/PWM control; CTMU provides capacitive touch keys; and USB enables service-port diagnostics. Compared to the PIC32MX130F256D, the PIC32MX150F256LT-V/PF adds USB for in-field firmware updates and AEC-Q100 V-grade screening for kitchen thermal environments. Companion ICs include the MCP8024 BLDC gate driver and the MCP9700 temperature sensor.

Notas de projeto
Power the PIC32MX150F256LT-V/PF from a 3.3V LDO with 100 mA of headroom. Place a 100 nF 0402 ceramic decoupling capacitor on every VDD/VSS pin pair (there are 5 pairs on the 100-pin TQFP) plus a single 4.7 uF bulk capacitor on the main VDD rail. The VUSB pin requires a separate 0.1 uF decoupling capacitor close to the pin. Estimate: at 50 MHz active mode the core draws approximately 30 mA, plus I/O drive current, so a 100 mA LDO provides adequate margin for transient peaks.
Route the 50 MHz crystal traces as short as possible with ground guard traces on both sides. Use a 4-layer PCB with a continuous ground plane directly under the MCU; the 100-pin TQFP thermal pad must be soldered to a copper pour connected to VSS to improve heat dissipation. Per Microchip application note AN833, the USB D+/D- traces must be matched length (within 150 mil) and have 90 ohm differential impedance. Route VDD/VSS power planes wide to support peak current transients during USB enumeration.
The PIC32MX150F256LT-V/PF has a 2.3V to 3.6V supply range - do NOT power it from 5V or you will damage the MCU. Use an external pull-up on MCLR (10 kOhm to VDD) to ensure clean reset. The PPS feature only remaps digital peripherals; analog functions (ADC inputs, analog comparators) are NOT remappable and must be assigned during board layout planning. Configure the JTAG/TRACE pins to GPIO or disable TRACE in code if not used, or the unused pins will float and add noise. For USB applications, install a 10 uF capacitor on VBUS if using bus-powered mode.
Estimate: the 100-pin TQFP package has a theta_JA of approximately 50 C/W on a standard JEDEC 4-layer test board. At +25C ambient and 30 mA active current at 3.3V (99 mW dissipation), the junction rises only ~5C. At +85C ambient industrial, junction reaches approximately 90C - well within the +105C V-grade limit. For automotive under-hood applications at +105C ambient, confirm board-level thermal simulation, particularly if the MCU drives high-current I/O loads continuously.
