PIC32MX150F128DT-50I/TL Overview
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a high-performance processor core, program memory (Flash), data memory (SRAM), and a rich set of peripherals into one package. Within the broader hierarchy, the PIC32MX family belongs to the MIPS32 architecture class of embedded controllers, which sit above 8-bit/16-bit MCUs in raw compute performance and below Cortex-M class parts in some mixed-signal features. The MX150F128D sub-family is positioned as a low-cost, USB-capable, graphics-capable general-purpose MCU line for cost-sensitive applications.
Key features distinguishing the PIC32MX150F128DT-50I/TL include 128KB Flash and 32KB SRAM, full-speed USB 2.0 device/host/OTG, an integrated 10-bit 1 Msps ADC, hardware crypto accelerator for AES/DES, and sub-0.5 mA/MHz active current consumption that supports long battery life in portable designs. The PPS remap block lets each peripheral signal be assigned to one of several physical pins, eliminating fixed-pin conflicts and simplifying PCB layout.
Architecturally, the device uses a 5-stage MIPS32 M4K pipeline, runs at 50MHz (with 40MHz also supported at industrial temperature), and pairs the core with a multi-channel DMA controller to offload memory-move tasks. The 44-pin VTLA package delivers a 0.65mm pitch and 0.9mm height for compact designs, while the exposed pad lowers junction-to-ambient thermal resistance.
Typical applications include USB peripherals (HID, CDC, mass-storage), small graphical user interfaces via PMP-driven TFT/STN displays, audio playback through I2S codecs, capacitive-touch control panels, and industrial sensor hubs. The 50MHz clock speed also supports lightweight TCP/IP stacks and modest RTOS workloads.
When designing with this MCU, prioritize firmware that uses the DMA to sustain I2S audio streams and reserve a PPS mapping table to avoid signal collisions. Plan for a 3.3V LDO with at least 100mA headroom and provide adequate decoupling on each VDD/VSS pair to maintain ADC accuracy.

Key Differentiators
- Higher 50MHz speed grade vs standard 40MHz variants (vs PIC32MX150F128D-I/TL)
- Doubles Flash and SRAM memory over PIC32MX150F128DT (vs PIC32MX130F256D-50I/TL)
- VTLA package with 0.65mm pitch for compact designs (vs PIC32MX150F128DT-50I/PT)
- Integrated USB 2.0 FS OTG with on-chip transceiver (vs PIC32MM0064GPM028-I/ML)
Design Notes
The PIC32MX150F128DT-50I/TL requires a clean 3.3V supply capable of delivering at least 100 mA during active USB transactions. Place a 10uF bulk capacitor plus a 0.1uF ceramic decoupling cap close to each VDD/VSS pair (pins 19/20, 33/34). The VUSB pin must be bypassed with a 0.01uF cap to ensure USB Full-Speed signal integrity. If the design is USB bus-powered, add a 4.7uF capacitor at VBUS to handle inrush transients per USB 2.0 specifications.
The 44-pin VTLA package has an exposed thermal pad that must be soldered to a copper pour on the PCB to meet thermal specifications. Estimated: at 50MHz full activity with 0.5 mA/MHz, the MCU draws about 25 mA from the 3.3V supply (82 mW). The junction-to-ambient thermal resistance of approximately 31 C/W results in a 2.5 C temperature rise above ambient - well within operating limits - but adequate ground-plane copper is still required for long-term reliability.
Route the USB D+ and D- traces as a 90-ohm differential pair with continuous ground reference and length matching within 2 mm. Keep clock traces short and away from analog inputs to minimize ADC coupling noise. Place a ground ring around the 44-pin VTLA land pattern and stitch vias every 5 mm around the perimeter. The exposed thermal pad requires an array of thermal vias (0.3 mm drill, 0.5 mm pitch) connecting the top copper pour to inner ground planes.
When migrating from the -I/TL (40 MHz) to -50I/TL (50 MHz) speed grade, verify that your firmware configures the system clock and peripheral dividers for the higher rate. Do not exceed 50 MHz or 3.6V VDD - this permanently damages the device. The Peripheral Pin Select (PPS) registers must be unlocked via the CFGCON register before remapping any peripheral - omitting this lock prevents pin changes. Always configure the analog/digital mode on shared pins before enabling digital peripherals to avoid contention.
