PIC32MX570F512L-50I/PT - 50MHz 512KB Flash MCU | Microchip
MPN: PIC32MX570F512L-50I/PT ✓ Hoạt độngPIC32MX570F512L-50I/PT Tóm tắt
A 32-bit microcontroller (MCU) is an embedded processor that integrates CPU, memory, and peripherals on a single die. Within the broader taxonomy, the PIC32MX570 sits in the 32-bit MCU category (above 8-bit and 16-bit MCUs), and within that family in the MIPS32 M4K architectural line. Compared with 8-bit PIC16/PIC18 devices, the PIC32MX core delivers roughly 10x the MIPS throughput while retaining Microchip's MPLAB X toolchain compatibility, easing migration for existing PIC firmware developers. The PIC32MX5xx sub-family specifically adds USB-OTG and CAN peripherals that are absent on lower-tier PIC32MX1xx/2xx parts.
Key features of the PIC32MX570F512L include Peripheral Pin Select (PPS) for flexible I/O mapping, a Charge Time Measurement Unit (CTMU) for capacitive touch sensing, a 16-bit Parallel Master Port (PMP) with dual read/write buffers for graphics interfaces, two I2S modules for audio codec interfaces, and an on-chip 8 MHz internal oscillator with PLL support up to 50 MHz. The device also includes a JTAG debugger interface, five 16-bit timers/counters, five input capture and five output compare modules, and a real-time clock calendar.
Architecturally, the M4K core combines single-cycle hardware multiply and a 5-stage pipeline, enabling deterministic interrupt response at 50 MHz. The 64 KB SRAM supports data buffering for USB isochronous transfers and CAN message handling simultaneously. The 512 KB Flash is organized as 256K x 16 with pre-fetch cache, accelerating instruction fetches at full clock rate.
Typical applications include USB audio headsets and USB-to-CAN bridges, industrial HMI panels with graphics LCDs, capacitive touch user interfaces, embedded web servers, and USB HID peripherals. The wide peripheral mix also suits motor control prototyping and medical instrumentation front-ends.
When designing with this MCU, allocate adequate decoupling capacitance near each VDD/VSS pair, ensure the 50 MHz PLL reference is within 50 ppm stability, and observe the I/O pin current limits of 15 mA source / sink when driving LEDs or relays directly. The -50I suffix denotes 50 MHz maximum clock and -40 C to +85 C industrial temperature range.

Ứng dụng tiêu biểu
PIC32MX570F512L-50I/PT phù hợp cho 6 Áp dụngs: USB Audio Headset / USB DAC, Industrial HMI with Graphics LCD, USB-to-CAN Bridge Gateway, Capacitive Touch User Interface, Embedded Web Server / IoT Edge Node, Medical Device Data Logger.
USB Audio Headset / USB DAC
The PIC32MX570F512L-50I/PT's integrated USB 2.0 Full-Speed OTG controller and two I2S modules make it ideal for USB audio peripherals such as USB headsets, USB DACs, and USB-to-S/PDIF bridges. The 50 MHz / 83 DMIPS throughput provides ample CPU headroom for sample-rate conversion and audio DSP, while 64 KB SRAM supports isochronous USB buffering at 48 kHz / 24-bit without dropouts. Two I2S modules allow simultaneous headphone and microphone paths, and the 10-bit ADC can be used for push-button or sidetone sampling.

Industrial HMI with Graphics LCD
The PIC32MX570F512L-50I/PT integrates a 16-bit Parallel Master Port (PMP) with dual read/write buffers, enabling direct connection to graphics LCDs and TFT displays up to 480x272 resolution without external bus multiplexers. The 83 I/O pins expose the full PMP data and address bus alongside CTMU-driven capacitive touch keys for industrial operator panels. The 50 MHz core and 64 KB SRAM deliver smooth menu refresh at 30+ FPS, and the 2.3-3.6 V supply range simplifies 3.3 V-only industrial designs.

USB-to-CAN Bridge Gateway
With both USB 2.0 Full-Speed OTG and CAN 2.0B (DeviceNet-compatible) integrated on-chip, the PIC32MX570F512L-50I/PT is a natural fit for USB-to-CAN gateway modules used in industrial automation, automotive diagnostics, and CAN-based sensor networks. The CPU runs the USB CDC host protocol on one side and the CAN bus arbitration on the other, while 64 KB SRAM buffers high-throughput message traffic. The 50 MHz MIPS32 M4K core handles both stacks simultaneously without DMA conflicts.

Capacitive Touch User Interface
The PIC32MX570F512L-50I/PT integrates a Charge Time Measurement Unit (CTMU) that measures capacitance to sub-picofarad resolution, enabling capacitive touch buttons, sliders, and proximity sensors without external touch ICs. Combined with 83 I/O pins and 10-bit ADC, the part supports 28+ touch channels for appliances, lighting controls, and consumer electronics. The 50 MHz core and 64 KB SRAM provide plenty of headroom for touch firmware filtering and gesture recognition algorithms.

Embedded Web Server / IoT Edge Node
The PIC32MX570F512L-50I/PT combines 512 KB Flash (sufficient for full TCP/IP stacks such as Microchip's Harmony), 64 KB SRAM, and a USB 2.0 Full-Speed OTG port to serve as a low-cost embedded web server or IoT edge node. The 83 I/O pins support SPI-based Ethernet MACs (e.g., ENC28J60) or Wi-Fi modules, while 4 SPI and 2 I2C peripherals handle sensor aggregation. The 50 MHz / 83 DMIPS performance is sufficient for HTTP/HTTPS, MQTT, and JSON parsing in resource-constrained edge devices.

Medical Device Data Logger
With 512 KB Flash for firmware and 64 KB SRAM for data buffers, the PIC32MX570F512L-50I/PT fits medical device data loggers for bedside monitors, pulse oximeters, and portable diagnostic peripherals. The 10-bit 1 MSPS ADC captures analog biosignals, and the USB-OTG port enables seamless patient data upload to PCs. The industrial -40 C to +85 C temperature range covers most clinical environments; the -V variant extends this to -40 C to +105 C for ambulance or field applications.

Ghi chú thiết kế
Place one 0.1 uF decoupling capacitor on each VDD pin (pins 7, 26, 44, 65, 89) as close as physically possible to the IC, and add one bulk 10 uF ceramic plus 100 uF electrolytic per VDD/VSS pair. The PIC32MX570F512L draws up to 75 mA active at 50 MHz, so the power trace from the LDO to VDD should be at least 0.5 mm wide on outer layers. Use a ferrite bead on the USB VBUS rail to suppress in-rush current during USB attach events.
Route the 50 MHz system clock trace as short as possible (under 25 mm), keep it over a continuous ground plane, and place a 33 ohm series damping resistor near the source. For USB, route the differential pair (D+/D-) with 90 ohm differential impedance, matching length within 2 mm, and avoid splits in the ground plane beneath the pair. The 100-pin TQFP requires at least a 4-layer PCB with dedicated power and ground planes for clean USB signaling.
Do not confuse the PIC32MX570F512L (100-pin) with the PIC32MX570F512H (64-pin) - they share the same silicon but the H variant lacks many I/O pins including portions of the Parallel Master Port. Always verify the /PT vs /PF package suffix when ordering - both are 100-pin TQFP but with slightly different lead footprints. Ensure the 8 MHz crystal or resonator has 50 ppm or better stability for USB Full-Speed compliance, and never operate the MCU above 3.6 V on any VDD pin.
The PIC32MX570F512L-50I/PT in the 100-pin TQFP package has a junction-to-ambient thermal resistance (theta_JA) of approximately 40 C/W. At 50 MHz full CPU load the typical active current is 60 mA at 3.3 V (about 0.2 W dissipation), so the self-heating temperature rise is around 8 C - well within the 85 C industrial limit. For high-temperature +85 C ambient applications, ensure 100 mm^2 of copper pour under the exposed die-attach pad and continuous airflow for margin.
Thông tin tuân thủ
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified as standard; the PIC32MX570F512L-V/PT variant extends temperature range but is still industrial grade, not full automotive qualification.
