PIC32MX250F128D-V/TL 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripheral interfaces. The PIC32MX1XX/2XX family sits within the broader MIPS32 architecture hierarchy and is designed for cost-sensitive embedded applications that still require USB connectivity and graphics peripherals. Within Microchip's portfolio this part bridges 8-bit PIC16/PIC18 designs and higher-end Cortex-M alternatives, offering the PIC toolchain (MPLAB X, XC32) and a mature DSP/USB library stack.
Key specifications include 83 DMIPS core performance (1.56 DMIPS/MHz), 0.5 mA/MHz typical active current, 2.3 V to 3.6 V supply, ten 16-bit timers plus two 32-bit timers, a 10-channel 10-bit ADC at 1 Msps, and an AEC-Q100 automotive grade rating. The 44-pin VTLA package has 34 general-purpose I/O pins and measures 8 x 8 mm with a 0.65 mm pitch and 0.90 mm profile, including an exposed thermal pad that must be soldered to the ground plane for proper thermal dissipation.
The MIPS32 M4K core uses a 5-stage pipeline and supports MIPS16e compressed instructions to reduce code size by up to 40%. Programmable PPS remaps most digital peripheral inputs/outputs to a wide range of physical pins, simplifying PCB routing and allowing late-stage BOM changes without board respins. The USB 2.0 full-speed OTG controller handles Host, Device, and On-The-Go roles in firmware, and the PMP bus drives external graphical LCDs.
Typical applications include USB HID peripherals (HID keyboards, mice, custom interfaces), embedded audio streamers via I2S, low-cost graphical HMI panels with PMP-driven LCDs, capacitive touch control surfaces using mTouch, and AEC-Q100 automotive body and infotainment sub-modules. Designers building on this part should pay attention to the 5 V tolerance of I/O pins, the need for a 24 MHz primary oscillator to derive USB clocks, and the exposed pad requirement for thermal management.

主な用途
PIC32MX250F128D-V/TL の用途: 6 件s: USB HID Peripherals, Automotive Body Control Modules, Embedded Audio Streaming Devices, Graphical HMI Panels, Capacitive Touch Control Surfaces, USB-to-UART Bridge / Industrial Gateway.
USB HID Peripherals
The PIC32MX250F128D-V/TL's integrated USB 2.0 full-speed device/host/OTG controller makes it an ideal host for USB HID peripherals such as keyboards, mice, custom HID interfaces, and game controllers. The 83 DMIPS MIPS32 M4K core executes the USB stack plus HID report processing with low latency, while 32 KB SRAM buffers HID reports and command sequences. The 128 KB Flash accommodates the Microchip USB stack (MCHPUSB or MLA USB) plus application logic. Two I2S/SPI modules can drive external LEDs or audio feedback while the USB enumeration is active.
おすすめ
Automotive Body Control Modules
AEC-Q100 qualification, -40C to +105C operating range, and the integrated USB OTG make the PIC32MX250F128D-V/TL a strong fit for automotive body control and infotainment sub-modules. The 34 GPIO pins drive MOSFET bridges for lighting, mirror, and seat control, while the 10-channel 10-bit ADC reads battery voltage, current sensing, and thermistor inputs. mTouch capacitive touch support replaces mechanical buttons in HMI subassemblies, and the 1 ns input capture measures PWM signals from automotive sensors with high precision.
おすすめ
Embedded Audio Streaming Devices
Two I2S/SPI modules combined with USB device capability make the PIC32MX250F128D-V/TL a compact audio streaming platform. The MCU decodes USB audio class 1.0 isochronous streams from a host PC and outputs I2S frames to an external DAC such as the PCM5102A. Programmable gain and sample rate conversion are handled in firmware on the MIPS32 M4K core. The exposed-pad VTLA package simplifies single-sided PCB layouts in compact consumer audio products such as USB DACs, headphone amplifiers, and Bluetooth dongles.
おすすめ
Graphical HMI Panels
The Parallel Master Port (PMP) on the PIC32MX250F128D-V/TL drives graphical LCDs up to QVGA resolution directly, eliminating the need for an external graphics controller. The 83 DMIPS core redraws menus, icons, and status indicators at 30+ fps while leaving headroom for touch processing via the mTouch peripheral. PPS remapping routes 34 GPIO signals to optimize PCB layout for slim HMI panels in industrial control, medical bedside terminals, and home automation gateways.
おすすめ
Capacitive Touch Control Surfaces
mTouch capacitive touch hardware plus the 1 ns resolution input capture enable the PIC32MX250F128D-V/TL to implement robust touch buttons, sliders, and proximity sensors. Charge-time measurement on up to 10 channels detects finger presence while the MIPS32 core runs the mTouch library to debounce, calibrate, and report events. AEC-Q100 qualification supports automotive door handle, steering wheel, and center console touch surfaces exposed to +105C ambient.
おすすめ
USB-to-UART Bridge / Industrial Gateway
Industrial USB-to-UART, USB-to-SPI, or USB-to-I2C bridges benefit from the PIC32MX250F128D-V/TL's USB device firmware stack and dual I2S/SPI modules. The 128 KB Flash stores the USB class driver plus vendor-specific protocol logic, and the 32 KB SRAM buffers high-speed CDC streams. Operating from 2.3-3.6 V lets the bridge tie directly into 3.3 V industrial MCU rails without level shifters, while PPS routing places UART, SPI, and I2C pins for optimum PCB escape.

設計ノート
The PIC32MX250F128D-V/TL core consumes 0.5 mA/MHz typical plus peripheral and I/O leakage. Estimated: at 40 MHz with USB active and I2S streaming, total IDD reaches roughly 30-35 mA, requiring the VDD rail to source at least 50 mA with adequate bulk decoupling (10 uF + 0.1 uF near each VDD/VSS pin pair). The on-chip 3.3V regulator output (VDDCORE) requires an external 10 uF low-ESR capacitor for stability.
Although the VTLA (TL) exposed-pad package has no formal theta_JA specification in the public datasheet, the exposed bottom plane is recommended to be soldered to a VSS copper pour covering at least 1 square inch of board area. Without this, the junction-to-ambient thermal resistance can exceed 60 C/W and the part will throttle or fail at sustained +105C ambient. Estimated: 1 square inch of 2 oz copper reduces theta_JA to roughly 35 C/W.
Place the 24 MHz primary oscillator crystal within 5 mm of the OSCI/OSCO pins, surrounded by a ground guard ring, to meet USB 2.0 full-speed timing accuracy requirements. The D+ and D+ traces must be 90 ohm differential with no stubs and equal length within 1 mm. Place the USB VBUS sense resistor divider near the VBUS pin with a 0.1 uF bypass. Keep PMP data/control traces short and length-matched for parallel LCD timing.
Three common pitfalls: (1) Forgetting to solder the exposed pad - the datasheet explicitly states 'metal plane at the bottom of the device is not connected to any pins and is recommended to be connected to VSS externally'. (2) Failing to configure the internal 3.3V regulator enable bit (DEVFN0/DEVFN1) - without it, the core will not start. (3) Using a non-USB-rated 24 MHz crystal - any frequency error over 0.25 percent will fail USB compliance tests per USB 2.0 spec.
