PIC32MX150F128C-V/TL Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (SRAM), and integrated peripherals such as timers, ADC, communication interfaces, and I/O. The PIC32MX family sits within Microchip's broader 32-bit portfolio (PIC32 > MIPS MCU > embedded processor > semiconductor IC), offering a balance of performance, peripherals, and power efficiency for connected embedded systems.
Key features include five 16-bit timers, a 10-bit 1 Msps ADC with up to 16 channels, two UART, two I2C, two SPI, PMP (Parallel Master Port), USB 2.0 full-speed device/host/OTG, peripheral pin select (PPS) for flexible signal routing, RTCC, CTMU (charge time measurement unit) for capacitive touch, and up to 21 general-purpose I/O lines. Internal 8 MHz and 32 kHz oscillators reduce external component count.
Architecturally, the M4K core is a 5-stage pipeline Harvard architecture delivering 1.56 DMIPS/MHz. Separate PLLs drive the system clock and USB clock, enabling flexible baud-rate generation. A 4-channel DMA engine offloads data movement to lower CPU load. Code is programmed via ICSP (In-Circuit Serial Programming) or JTAG using any PGECx/PGEDx pair.
Typical applications include USB HID peripherals, sensor interfaces with capacitive touch, automotive body controllers, audio playback devices, simple graphics displays, and low-cost IoT nodes. The USB, RTCC, and CTMU peripherals make it well-suited for connected sensor hubs and HMI subsystems.
Design tip: ensure all VDD and VSS pins are connected and decoupled with 100 nF ceramic capacitors placed close to the package. For USB applications, the VUSB pin requires a 100 nF bypass to ground and a 10 uF bulk capacitor.

Typical Applications
PIC32MX150F128C-V/TL is suitable for 6 applications: USB HID Peripheral Devices, Automotive Body Controllers, Capacitive Touch Sensor Interfaces, Industrial Sensor Hubs, Simple Graphics Display Controllers, Low-Cost Audio Playback Devices.
USB HID Peripheral Devices
The PIC32MX150F128C-V/TL is well-suited for USB HID peripherals thanks to its on-chip USB 2.0 full-speed OTG controller, dedicated 48 MHz USB PLL, and integrated transceiver, which remove the need for an external PHY. With 128 KB Flash and 32 KB SRAM, the device fits HID stacks, bootloader code, and application firmware simultaneously. The 40 MHz M4K core drives polling rates above 1 kHz while maintaining sub-frame latency, important for keyboards, mice, and game controllers. Compared to a discrete USB MCU + regulator solution, this part consolidates power management and USB in a single 5x5 mm VTLA footprint.
Recommended
Automotive Body Controllers
AEC-Q100 qualification makes the PIC32MX150F128C-V/TL a candidate for automotive body-control modules including lighting, HVAC panels, and seat controllers. LINbus support directly interfaces with vehicle body networks, while the CTMU peripheral enables capacitive touch buttons on door handles and overhead consoles. The 36-VTLA package is small enough for tight instrument-cluster PCBs, and the industrial/peripheral mix (5 timers, 10-bit ADC, RTCC) handles wake-on-LIN duty cycling. Verified distributor data confirms AEC-Q100 stress testing, qualifying it for cabin-mounted ECUs with -40C to +125C exposure.
Recommended
Capacitive Touch Sensor Interfaces
The on-chip CTMU (Charge Time Measurement Unit) enables reliable capacitive touch sensing with up to 16 channels multiplexed through the 10-bit ADC. The PIC32MX150F128C-V/TL can implement touch buttons, sliders, and proximity sensors without external touch ICs, reducing BOM cost and PCB area. The peripheral pin select (PPS) feature allows reassignment of touch channels to alternative pins during PCB layout rework. Combined with RTCC for sleep/wake scheduling, the part delivers sub-10 uA touch standby current for battery-powered doorbells, remote controls, and kitchen appliances.
Recommended
Industrial Sensor Hubs
With two UART, two I2C, two SPI, and PMP interfaces, the PIC32MX150F128C-V/TL can aggregate data from multiple sensors (temperature, pressure, accelerometers) and forward them to a host via USB or UART bridge. The 4-channel DMA engine offloads serial data movement, leaving the M4K core free for calibration and filtering. Industrial-grade -40C to +85C variants handle factory-floor environments. Verified web data confirms connectivity options including IrDA and LINbus, which extend the part to legacy fieldbus nodes.
Recommended
Simple Graphics Display Controllers
The Parallel Master Port (PMP) on the PIC32MX150F128C-V/TL drives small TFT LCDs up to 8-bit wide with DMA-driven refresh, enabling cost-effective HMI graphics without external display controllers. The 40 MHz core supports fluid refresh rates on 320x240 panels, while the 32 KB SRAM handles frame buffers for compact GUIs. The 36-VTLA footprint fits behind 2.4-inch displays, ideal for thermostat screens, e-bike dashboards, and appliance UIs.
Recommended
Low-Cost Audio Playback Devices
The PIC32MX150F128C-V/TL features audio-specific peripherals including I2S capability through its SPI peripheral and DMA-driven sample transfer, enabling low-cost MP3/AAC playback from SPI Flash or SD cards. With 128 KB Flash holding small audio codecs and 32 KB SRAM supporting 16-bit 44.1 kHz ping-pong buffers, the part fits doorbells, talking toys, and message-annunciation systems. PWM outputs can drive Class D amplifiers directly, eliminating external DACs in mono-audio designs.

Key Differentiators
- Pin-compatible automotive-grade variant exists for dual-sourcing (vs PIC32MX150F128C-I/TL)
- Higher Flash density with same footprint (vs PIC32MX130F256D-V/TL)
- Higher clock speed option within same package (vs PIC32MX150F128C-50I/TL)
Design Notes
Estimated: Connect every VDD/VSS pair on the PIC32MX150F128C-V/TL with a 100 nF X7R ceramic bypass capacitor placed within 3 mm of each pin. Add a single 10 uF bulk capacitor on the 3.3V rail. For USB applications, the VUSB pin must have a 100 nF bypass to ground and a 10 uF bulk capacitor on the USB rail to meet USB 2.0 full-speed edge monotonicity.
Solder the exposed thermal pad of the 36-VTLA package to a continuous copper pour on the top layer with multiple thermal vias to inner ground planes. This both reduces thermal resistance (theta JA of approximately 30 C/W on a 4-layer JEDEC test board) and improves electrical grounding. Recommended PCB land pattern follows IPC-7351 nominal density for VTLA 5x5 mm.
Always pair PGECx with PGEDx: if you wire PGEC2 to the programmer clock, ICSPDAT must connect to PGED2. Mixing PGEC1 with PGED2 will fail ICSP. Also note that Peripheral Pin Select (PPS) must be unlocked via CFGCON bit 13 before reassignment; failure to unlock silently ignores PPS writes, a common source of 'pin does not toggle' debugging sessions.
For USB designs, route the D+ and D- traces as a 90 ohm differential pair with length matching to within 150 mils. Keep the traces short and avoid vias. Place the VUSB bypass network close to the IC. Verified web data confirms USB 2.0 full-speed support, which uses 12 Mbps signalling that is forgiving but still requires impedance control to pass USB compliance.
