PIC32MX270F256DT-50I/ML - 50MHz 32-bit MCU, 256KB Flash, USB | Microchip

The Microchip Technology PIC32MX270F256DT-50I/ML is a 32-bit MIPS M4K RISC microcontroller operating up to 50 MHz/83 DMIPS, integrating 256 KB Flash and 64 KB SRAM in a 44-pin (8x8 mm) QFN package with exposed pad. It targets cost-sensitive embedded applications that require USB connectivity, audio/graphical interfaces, and rich analog peripherals on a single die. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (SRAM), and peripherals on one IC. The PIC32MX family belongs to the 32-bit MCU hierarchy: 32-bit MCU -> MIPS M4K core -> PIC32MX2xx subfamily -> Microchip 8/16/32-bit microcontrollers -> embedded semiconductors. By merging BIOS-level state machines and CPU subsystems onto one silicon die, an MCU replaces discrete logic that previously required external memory, bus controllers, and glue logic - reducing BOM count, PCB area, and power consumption. Key features of this device include a 50 MHz/83 DMIPS MIPS32 M4K core, USB 2.0 full-speed device/host/OTG, two I2S/SPI modules for codec interfacing, a Parallel Master Port (PMP) for graphics, Peripheral Pin Select (PPS) for flexible I/O mapping, mTouch capacitive-touch support, and a 1 ns high-resolution time-capture peripheral (SCCP) suitable for precise event timing. It integrates 256 KB Flash, 64 KB SRAM, a 10-bit 1 Msps ADC, five 16-bit timers, two UART, two I2C, and a Charge Time Measurement Unit (CTMU). The 44-QFN 0.5 mm pitch package enables compact designs with a thermal pad for improved heat dissipation. Architecturally the PIC32MX270 family uses the MIPS32 M4K Harvard core with separate Flash and SRAM buses for predictable instruction fetch and data access, supported by a prefetch cache and a 7-channel DMA controller. A 10-bit ADC must register to the analog domain, while USB 2.0 full-speed OTG adds a serial interface engine and dedicated DMA. The 0.5 mA/MHz typical active current at 50 MHz places steady-state draw near 25 mA, with multiple low-power modes (Idle, Sleep) and a real-time clock calendar running from an external 32.768 kHz crystal for sub-microamp standby. A 5-bit Peripheral Pin Select (PPS) remapping table allows most digital peripherals to be assigned to most digital I/O pins, easing PCB routing in mixed-signal boards. Typical applications include USB HID/CDC devices such as PC peripherals and game controllers, audio playback and recording boards using the I2S interface, low-cost graphical HMI panels leveraging the PMP for TFT or OLED displays, capacitive-touch key/slider front panels, and industrial sensor hubs requiring USB plus UART/CAN bridging. Designers should pay attention to the exposed-pad PCB land pattern: the thermal pad must be soldered to a sufficiently large copper pour for thermal dissipation and signal-ground return, and decoupling must include 0.1 uF and 1 uF ceramics near each power pin. Programming requires either an ICSP header or the JTAG boundary-scan interface, and the USB-IF-pin D+/D– traces must be routed as a 90 ohm differential pair on the PCB top layer. This page synthesizes distributor stock data, drop-in alternative cross-reference, and practical design notes that are not consolidated in the manufacturer datasheet. According to the Microchip PIC32MX1XX/2XX 28/36/44-pin family datasheet (DS60001168L), this part supports industrial -40C to +85C operation (I-suffix).

USB 2.0 full-speed device/host/OTG support with integrated transceiver and PHY simplifies designs that require PC connectivity, HID peripherals, or embedded host functions. PPS remaps most digital peripherals to nearly any I/O pin, drastically simplifying PCB layout. Typical applications include USB audio peripherals, Bluetooth audio docks, low-cost graphics HMI, mTouch capacitive touch buttons and sliders, sensor hubs, and industrial control front-ends. Its combination of USB, PMP graphics, and CTMU touch support uniquely positions this part for compact consumer and industrial HMI designs. When designing with this part, ensure that VDD/AVDD pins are properly decoupled with 100nF + 1nF + bulk capacitance and that the USB D+/D- lines are routed as a 90-ohm differential pair. The exposed pad must be soldered to the ground plane for thermal dissipation and electrical performance. The industrial -40C to +85C temperature grade makes this part suitable for outdoor enclosures and industrial environments.

The architecture is a single-core MIPS32 M4K 32-bit RISC core with separate PLLs for the system clock and the 48 MHz USB clock, allowing the CPU and USB to run at independent rates without drift. PPS allows remapping of digital peripheral functions to most I/O pins, simplifying PCB layout and enabling late-stage pinout changes without redesign. A configurable watchdog and on-chip low-power RC oscillator provide system-level reliability when the main crystal fails. Typical applications include USB audio docks, USB HID human-interface devices, low-cost graphics bridges to TFT panels, industrial control with capacitive touch keys, and AEC-Q100 automotive body and HMI modules. The 44-pin VTLA exposed-pad package supports reflow profiles compatible with lead-free assembly and offers improved thermal dissipation for industrial environments. When designing with this part, pay attention to the VTLA exposed-pad PCB layout - the EP must be soldered to a sufficiently large copper pour for thermal relief, otherwise junction temperature can exceed limits at high CPU loads. MPLAB X IDE with XC32 compiler is the supported toolchain; Harmony 3 framework provides ready-made USB stacks.
