PIC32MX174F256DT-I/ML - 72MHz 32-bit MCU 256KB Flash | Microchip

The Microchip PIC32MX174F256DT-I/ML is a 32-bit MIPS M4K microcontroller running up to 72 MHz, integrating 256 KB of Flash and 64 KB of SRAM in a 44-pin QFN (8x8 mm) package, and belongs to the PIC32MX1xx/2xx XLP family with on-chip Full-Speed USB 2.0. What is a 32-bit microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripherals such as timers, communication interfaces, and analog blocks. The PIC32MX family uses the MIPS32 M4K core, a Harvard-architecture RISC processor with single-cycle multiplication, sitting in the broader hierarchy: MCU -> embedded controller -> semiconductor. The XLP (eXtreme Low Power) variants add aggressive power-saving modes that extend battery life in always-on products. Key features include 72 MHz core clock with 83 DMIPS performance, 256 KB Flash (256K x 8), 64 KB SRAM, Full-Speed USB 2.0 Device/Host/OTG, three comparators with a CTMU (Charge Time Measurement Unit) for touch and capacitive sensing, a Real-Time Clock and Calendar (RTCC), and the standard PIC32 peripheral set: I2C, SPI, UART, PMP, ADC, and JTAG programming/debug. The 44-QFN package reduces PCB footprint while exposing up to 34 usable I/O pins. Architecturally, the device pairs the M4K core with a multi-vector interrupt controller, hardware DMA into dedicated RAM regions, and a peripheral bus that allows ADC and USB transfers without CPU intervention. Deep-sleep current is in the microamp range thanks to dedicated low-power regulator and RTCC retention, while the 72 MHz operation delivers enough headroom for USB stacks, graphics libraries, and sensor-fusion algorithms. Typical applications include low-power IoT sensor nodes with USB, consumer wearables, USB HID peripherals (keyboards, mice, custom input devices), capacitive-touch user interfaces, industrial control panels, and educational/development boards. The combination of XLP operation and FS USB makes the part especially attractive for tethered battery-powered devices that occasionally need to enumerate as a USB device. When designing with this MCU, ensure the VUSB 3.3V rail is stable before USB enumeration and provide a 1uF bypass on VCAP for the internal core regulator. JTAG/ICSP pins should be reserved on the PCB for in-circuit programming, and unused I/O must be configured as outputs low to minimise sleep current.

The 28-SSOP package keeps the part compatible with hand-soldering and breadboarding, which is helpful in prototype and small-volume runs. When designing with this MCU, allocate 4 Kbytes for bootloader + 28 Kbytes for application when using the USB bootloader, and ensure the 3.3V rail is clean (LDO, not switcher) because the 10-bit ADC is sensitive to ripple near the MCU supply pins. Use Microchip's MPLAB X IDE and Harmony v3 framework for pin configuration and peripheral drivers; the device is also supported by the open-source pic32prog and xc32 toolchain.

PIC32MX220F032BT-50I/SO

PIC32MX220F032BT-50I/SO - 32-bit MCU 32KB Flash 50MHz USB | Microchip

The Microchip Technology PIC32MX220F032BT-50I/SO is a 32-bit MIPS32 M4K PIC microcontroller running at 50 MHz, with 32 KB of Flash program memory and 8 KB of SRAM, integrated USB 2.0 full-speed, CTMU, RTCC and a 28-pin SOIC wide package. The 'T' suffix denotes industrial tape-and-reel packaging while 'I' denotes the industrial temperature grade of -40C to +85C. A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals such as timers, communication interfaces and ADCs. PIC32MX220 MCUs are positioned in Microchip's product taxonomy as MCU -> 32-bit microcontroller -> MIPS M4K core -> PIC32MX family -> entry-level connectivity (USB). They target embedded designs that need more code space and arithmetic headroom than 8-bit/16-bit PIC MCUs, while remaining easy to migrate to from existing PIC24/PIC32 code bases. Key features of the PIC32MX220F032BT-50I/SO include a MIPS32 M4K core with single-cycle multiply and hardware divide, 32 KB Flash / 8 KB SRAM, integrated USB 2.0 full-speed Device/Host/OTG controller, 10-bit ADC with up to 13 channels, three analog comparators, RTCC with calendar mode, CTMU for capacitive touch or time measurement, Peripheral Pin Select (PPS) for flexible pin mapping, and 4-channel hardware DMA. The 28-SOIC package offers generous I/O access in a wide-body footprint suitable for hand-soldered prototypes and industrial modules. The architecture uses a 5-stage pipeline with separate buses for Flash and RAM, allowing concurrent instruction fetch and data access. The USB module has its own PLL (96 MHz / 48 MHz) decoupled from the system PLL, ensuring jitter-tolerant USB signaling even when the system clock is reconfigured. PPS lets the user remap most digital peripherals to any available I/O pin, simplifying PCB routing for densely populated boards. Typical applications include USB HID peripherals (keyboards, mice, custom joysticks), USB-to-UART bridges, low-cost data loggers with RTCC timestamping, capacitive touch key panels using CTMU, and industrial sensor interfaces where 32-bit arithmetic is needed for linearization. The wide 28-SOIC package also makes this part well-suited for educational development boards and breadboard-friendly designs. When designing with this device, ensure that VBUS sensing is wired correctly if USB Device mode is used, and add the recommended 0.1 uF + bulk capacitor network close to the VDD/VSS pins. The PPS feature means firmware must configure pin mapping before peripheral use; the IOL1WAY fuse prevents write-after-write glitches when changing remappable pins at runtime.

PIC32MX220F032BT-50I/SS

PIC32MX220F032BT-50I/SS - 50MHz 32-bit MCU 32KB Flash SSOP-28 | Microchip

The Microchip Technology PIC32MX220F032BT-50I/SS is a 32-bit MIPS32 M4K RISC microcontroller running at 50 MHz with 32 KB of Flash program memory and 8 KB of SRAM, housed in a 28-pin SSOP (Shrink Small Outline Package). It belongs to the PIC32MX1XX/2XX 28/36/44-pin family and integrates USB 2.0 full-speed, three analog comparators, a 10-bit ADC with up to 13 input channels, two I2S/SPI modules, a Charge Time Measurement Unit (CTMU), and a Parallel Master Port (PMP) for graphics interfaces. A 32-bit microcontroller is an integrated circuit containing a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals such as timers, communication controllers, and analog blocks on a single silicon die. In the embedded hierarchy, MCUs sit above 8/16-bit microcontrollers but below application processors, and they dominate real-time control, sensor interfacing, and USB-connected device applications where deterministic interrupt response and low BOM cost matter most. Key features of the PIC32MX220F032BT-50I/SS include Peripheral Pin Select (PPS) which remaps digital peripherals to any I/O pin, hardware RTCC with calendar mode, five 16-bit timers/counters, two UART modules, and an operating voltage range of 2.3V to 3.6V. Typical active current is below 0.5 mA/MHz at 50 MHz and the industrial temperature grade supports -40C to +85C operation. Architecturally the device pairs a 5-stage pipelined MIPS32 M4K core capable of 83 DMIPS with a multi-vector interrupt controller and a flexible DMA engine, delivering strong throughput for USB stacks and graphics rendering through PMP. The CTMU enables mTouch capacitive touch sensing without an external timer IC. Typical applications include USB audio/Class-D device controllers, capacitive touch user interfaces, low-cost graphics HMI panels, sensor data loggers, and industrial control front-ends. Design tip: ensure the 28-pin SSOP land pattern uses 0.65 mm pitch with proper thermal relief on VDD/VSS pins and add a 1 uF + 0.1 uF decoupling pair within 3 mm of the supply pins. This page combines current distributor pricing, drop-in same-package alternatives, and design considerations drawn from the Microchip datasheet.
