PIC32MX150F256LT-50I/GJX Overview
A PIC32MX microcontroller belongs to the 32-bit MCU family (hypernym chain: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS-based MCU -> semiconductor IC). The PIC32MX1XX/2XX series is Microchip's mid-range 32-bit family, bridging 8-bit PIC16/PIC18 designs and the higher-end PIC32MZ line. It uses the MIPS32 M4K core with hardware multiply/divide and a 5-stage pipeline, delivering ~1.56 DMIPS/MHz. The on-chip FPU is absent in this family; math-heavy DSP code runs in fixed-point.
Key features of the PIC32MX150F256LT-50I/GJX include 256 KB single-cycle Flash with live update support, 32 KB SRAM, 16-channel 10-bit ADC at 1 Msps, five 16-bit timers, two I2C, two UART, two I2S, four SPI, and a Parallel Master Port. The CTMU (Charge Time Measurement Unit) enables touch sensing and precise time-of-flight measurements. PPS remaps digital peripherals to nearly any I/O pin, simplifying PCB routing.
Architecturally, the device uses a Harvard-style bus with separate Flash and SRAM paths, a prefetch module that mitigates flash wait states at 50 MHz, and a multi-vectored interrupt controller. The PMP peripheral can drive external graphics controllers or SRAM, while DMA offloads I2S, ADC, and UART transfers, leaving the CPU free for application logic.
Typical applications include audio playback/recording with I2S codecs, low-resolution TFT graphics via PMP, USB-less HMI boards, industrial sensor hubs, and cost-sensitive consumer products needing 32-bit performance. The wide peripheral mix suits IoT edge nodes and motor-control front-ends.
Designers should allocate a 2.5 V or 3.3 V LDO with adequate bulk capacitance and route the 50 MHz traces as controlled impedance. For 100-pin TFBGA, use 0.4 mm-pitch escape routing and a 4-layer stack-up with continuous GND pour. Always program the configuration bits (windowed watchdog, oscillator selection) before the first instruction fetch.

Typical Applications
PIC32MX150F256LT-50I/GJX is suitable for 6 applications: Audio Playback and Recording Systems, Industrial Sensor Hubs and Data Acquisition, Low-Resolution TFT HMI and Graphics Interfaces, USB-less Consumer Embedded Products, IoT Edge Nodes and BLE Bridge Boards, Motor Control and PWM Front-Ends.
Audio Playback and Recording Systems
The PIC32MX150F256LT-50I/GJX suits I2S-based audio products where dual I2S interfaces and DMA offload matter. Its 50 MHz M4K core delivers 83 DMIPS, easily running audio codecs at 48 kHz/16-bit alongside light UI logic, while 32 KB SRAM holds double-buffered PCM frames for glitch-free playback. Designers pair the chip with low-power stereo codecs (e.g., Microchip's WM8904) and route I2S, I2C control, and DMA streams over the Parallel Master Port when a small TFT is added. Compared with 8-bit PIC16/PIC18 devices, this part removes the need for codec pre-mixing in software. Estimated: with VDD = 3.3 V and full DMA utilization, the core stays below 25 mA during stereo 48 kHz playback.
Recommended
Industrial Sensor Hubs and Data Acquisition
With a 16-channel 10-bit ADC at 1 Msps, eight DMA channels, and 5x 16-bit timers, the PIC32MX150F256LT-50I/GJX handles multi-sensor aggregation in industrial nodes. The CTMU enables capacitive touch or time-of-flight distance measurement for proximity and level sensing, while 32 KB SRAM buffers sensor frames before UART/SPI uplinks. Industrial -40C to +85C qualification and 2.3 V to 3.6 V operation simplify integration with 3.3 V sensor rails and battery-backed supercaps. Designers typically chain UART to RS-485 transceivers and use PPS to remap peripherals around layout constraints, eliminating trace crossings on dense sensor boards.
Recommended
Low-Resolution TFT HMI and Graphics Interfaces
The PIC32MX150F256LT-50I/GJX integrates a Parallel Master Port (PMP) with dual read/write buffers, enabling direct interface to small TFT controllers without external logic. Its 50 MHz core supports typical WQVGA 480x272 panels, refreshing 60 Hz with 16-bit color from 32 KB frame buffer plus tile cache. Peripheral Pin Select routes 8-bit data, sync, and PWM-controlled backlight across any 8 GPIOs, simplifying PCB stackups. For monochrome OLED, the same PMP drives SSD1309 controllers with no extra bus logic. Compared to SPI-only MCUs that struggle past QVGA, this PIC32 part adds headroom for touch scanning and on-screen animations.
Recommended
USB-less Consumer Embedded Products
For consumer devices without USB (home appliances, toys, fitness accessories), the PIC32MX150F256LT-50I/GJX delivers strong 32-bit performance at modest cost. Its two UART, two I2C, four SPI, and two I2S cover Bluetooth/BLE daughter modules, MEMS microphones, and segment LCDs. The 256 KB Flash accommodates rich UI logic, BLE state machines, and simple RTOS kernels, while 32 KB SRAM supports message queues. The TFBGA package saves space in slim enclosures; designers verify JTAG/ICSP routing for factory programming and reserve the two I2S interfaces for an external DAC path on premium SKUs.
Recommended
IoT Edge Nodes and BLE Bridge Boards
The PIC32MX150F256LT-50I/GJX pairs naturally with a Bluetooth or sub-GHz radio daughter module for IoT edge gateways. Its 4 SPI, 2 UART, and PPS routing allow concurrent connections to BLE modems, sensors, and an external NOR flash. 32 KB SRAM holds TLS/HTTP stacks for cloud-bootstrap sequences, while 256 KB Flash accommodates Over-The-Air update images with rollback. Operating at 2.3 V to 3.6 V, the part works directly from a 3.3 V LDO downstream of a battery charger. Compared to bare 8-bit MCUs, this design frees engineers to implement secure boot, encrypted firmware, and local analytics.
Recommended
Motor Control and PWM Front-Ends
The PIC32MX150F256LT-50I/GJX provides five 16-bit timers plus PPS, enough for brushless DC motor commutation, servo control, or stepper sequencing at modest RPMs. The 50 MHz core can run field-oriented control loops for low-power BLDC fans, with the 10-bit ADC sampling back-EMF at the required PWM rate. DMA-driven ADC transfers keep timing jitter minimal, while 32 KB SRAM holds diagnostic buffers. Designers add external gate drivers and current-sense amplifiers because the MCU lacks on-chip high-side drivers. For higher-power three-phase systems, consider PIC32MK devices with built-in PWM modules.

Key Differentiators
- Mature MIPS32 M4K core with 83 DMIPS at 50 MHz (vs PIC32MX130F256D-50I/PT)
- Dual I2S plus Parallel Master Port (PMP) for graphics/audio (vs PIC32MX170F256LT-50I/GJX)
- 100-ball TFBGA in compact 7x7 mm outline (vs PIC32MX150F256LT-50I/PT)
Design Notes
The 100-ball TFBGA (7x7 mm, 0.4 mm pitch) requires 4-layer PCB stack-up with 0.2 mm (8 mil) vias-in-pad and a continuous GND plane under the BGA. Escape route on the top layer uses micro-vias; signal traces fan out on internal layers 2 and 3 with reference to GND/VCC. Use ENIG finish to ensure reliable BGA solder joints and avoid HASL for fine-pitch parts. Estimated: at 0.4 mm pitch, design rule check (DRC) needs 0.075 mm clearance and 0.075 mm trace width.
Power the PIC32MX150F256LT-50I/GJX from a 3.3 V LDO with at least 200 mA headroom; place 0.1 uF ceramic decoupling caps on every VDD pin and a 4.7 uF bulk cap on the regulator output within 10 mm of the BGA. The analog supply AVDD must be filtered through a ferrite bead from VDD, with its own 0.1 uF + 10 uF cap. Estimated: at 50 MHz full-load active mode, the core draws ~25 mA; sleep current drops to <20 uA with all peripherals off.
Always configure the FSOSCEN, FNOSC, and POSC bits in the DEVCFG0/DEVCFG1 configuration words before the first instruction fetch - leaving the device in the default FRC mode can mislead early firmware debugging. Also ensure JTAGEN is disabled in production for security, and add proper BOR (brown-out reset) thresholds matched to your LDO dropout. For TFBGA, watch for cold solder joints on center balls; use X-ray inspection during NPI.
Use Peripheral Pin Select (PPS) to route digital peripherals away from analog signals - keep ADC inputs on dedicated ANx pins whenever possible to avoid switching-noise coupling. Place the 32.768 kHz crystal as close as possible to the SOSCO/SOSCI pins with a ground guard ring. If using I2S, route MCLK, BCLK, and LRCK as length-matched pairs (within 5 mm) to avoid timing drift in audio frames.
Compliance Information
