PIC32MX150F128DT-I/TL - 32-bit MCU, 128KB Flash, 44-pin VTLA | Microchip
MPN: PIC32MX150F128DT-I/TL ✓ Hoạt độngPIC32MX150F128DT-I/TL Tóm tắt
A 32-bit microcontroller (MCU) is an integrated circuit that combines a high-performance processor core, program memory (Flash), data memory (SRAM), and a configurable set of peripherals on a single die. PIC32MX devices sit within Microchip's PIC32 family, targeting applications that need more computational headroom and richer peripherals than 8-bit PIC MCUs while retaining the familiar MPLAB X toolchain. The M4K core executes most instructions in a single cycle and supports DSP extensions.
Key specifications include 128 KB (128K x 8) Flash, 32 KB SRAM, 21 general-purpose I/O lines (some sources cite up to 34 GPIOs depending on multiplexing), five 16-bit timers, a 16-bit Input Capture, a 16-bit Output Compare/PWM, and an on-chip temperature sensor. The device runs from 2.3 V to 3.6 V and supports an industrial temperature range of -40 °C to +105 °C. Pin-to-pin compatible siblings in the VTLA-44 package range from 64 KB up to 256 KB Flash.
Architecturally, the PIC32MX150F128D uses a 5-stage pipeline MIPS32 M4K core, separate 32-bit instruction and data buses, and dedicated peripherals reachable via PPS remapping for flexible PCB routing. The integrated USB 2.0 full-speed device controller, combined with audio (I2S) and graphics (PMP) interfaces, makes it well suited for connected multimedia and human-machine interface (HMI) nodes.
Typical applications include USB audio peripherals, low-cost HMI boards with TFT panels, capacitive-touch user interfaces using mTouch, industrial control nodes with USB diagnostics, and consumer graphics accessories. The wide peripheral mix and USB support let one chip replace a discrete MCU plus external controller.
When designing with this part, verify the I/O count and PPS mapping for your specific signal layout - VTLA-44 exposes fewer pins than TQFP-44. Plan for a 2.3-3.6 V supply with adequate bulk decoupling near VDD/VSS pairs, and use MPLAB X with XC32 for firmware development.
This page synthesizes distributor pricing, pin-compatible alternatives in the same VTLA-44 footprint, and practical design notes that go beyond the manufacturer datasheet.

Ghi chú thiết kế
Provide a bulk 10 µF ceramic or tantalum capacitor plus a 0.1 µF decoupling capacitor on every VDD/VSS pair of the PIC32MX150F128DT-I/TL. Place the 0.1 µF cap within 2-3 mm of the supply pins to suppress switching transients during USB packet transmission. For USB bus-powered designs, add 10 µF on VBUS and a ferrite bead to isolate analog VDD from digital switching noise.
Route the USB D+ and D+ lines as a 90 Ω differential pair with matched length to within 2 mm, and keep them away from high-frequency switching signals. The VTLA-44 (6x6 mm) package has a small thermal pad underneath; connect it to a copper pour to keep the M4K core within the -40 to +105 °C industrial range during sustained USB activity. Avoid placing the IC near I2S MCLK traces to minimize coupled jitter.
Do not exceed the 3.6 V absolute maximum on VDD - even brief over-voltage during USB hot-plug can latch-up the PIC32MX150F128DT-I/TL. Configure unused I/O as outputs low (not inputs floating) to minimize supply current. When migrating firmware from a PIC32MX1XX to PIC32MX2XX sibling, check the PPS input/output mapping table; some peripherals shift to different RPn pins. Verify the VBUSON function is enabled in firmware before relying on USB host detection.
