PIC32MX570F512L-V/PF - 32-Bit MCU 512KB Flash 64KB RAM 100-TQFP | Microchip
MPN: PIC32MX570F512L-V/PF ✓ Hoạt độngPIC32MX570F512L-V/PF Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (RAM), and programmable peripherals into one package. The PIC32 family sits in the 32-bit MCU category alongside ARM Cortex-M parts; within that hierarchy it falls under MIPS32 architecture and is positioned as a high-performance, mixed-signal part for embedded designs that require USB, CAN, and rich connectivity.
Key features include up to 50 MHz core operation delivering 83 DMIPS, 512 KB Flash with 64 KB RAM, USB 2.0 Full-Speed On-The-Go, and CAN 2.0B with DeviceNet-ready addressing. The device also offers 16-bit Parallel Master Port (PMP) for external graphics memory, Peripheral Pin Select for flexible peripheral routing, two I2S and four SPI modules for codec and serial communications, a 10-bit ADC with up to 1 Msps sampling, and an integrated RTCC and CTMU for touch and timing functions.
Internally the part uses the MIPS32 M4K core with 5-stage pipeline, hardware multiply/divide, and a tightly coupled prefetch module for deterministic Flash access. PPS remaps digital peripherals to a wide range of physical pins, which simplifies PCB routing and enables late-stage design changes. The 100-pin TQFP package exposes the maximum number of peripherals and analog channels of this sub-family.
Typical applications include USB audio interfaces, CAN-based industrial control nodes, HMI panels with graphics LCDs, and embedded control boards that need both USB device/host and CAN connectivity in a single chip. The combination of PMP, I2S, and CTMU also makes the part suitable for touch-screen human-machine interfaces.
When designing with this device, ensure the supply rail stays within 2.3 V to 3.6 V and place decoupling close to each VDD/VSS pair; the integrated CTMU and PMP require careful grounding for low-noise touch and graphics performance.

Ứng dụng tiêu biểu
PIC32MX570F512L-V/PF phù hợp cho 6 Áp dụngs: USB-CAN Industrial Bridge, HMI Panel with Graphics LCD, USB Audio Interface, CAN-Based Industrial Control Node, Touch-Screen User Interface, Automotive Body Control Module.
USB-CAN Industrial Bridge
The PIC32MX570F512L-V/PF is ideal for USB-to-CAN bridge nodes thanks to its integrated USB 2.0 Full-Speed OTG controller and CAN 2.0B module with DeviceNet addressing support. The 50 MHz MIPS32 M4K core provides enough throughput to handle full-speed USB traffic while forwarding CAN frames with minimal latency, and the 512 KB Flash accommodates USB and CAN protocol stacks plus application firmware. The 64 KB SRAM allows buffering of CAN frames and USB packets simultaneously, reducing host-side polling. Power the part from a 3.3 V regulated rail and add ESD protection on the USB D+/D- lines and CANH/CANL bus pins.

HMI Panel with Graphics LCD
The PIC32MX570F512L-V/PF drives graphics LCDs through its 16-bit Parallel Master Port (PMP) with dual read/write buffers, eliminating external display controller cost in cost-sensitive HMIs. The 50 MHz core and 64 KB SRAM provide headroom for frame-buffer manipulation and touch event processing, while Peripheral Pin Select (PPS) routes SPI, I2C, and PWM to any available pin. The integrated CTMU simplifies resistive touch-screen biasing and ADC sampling, reducing analog front-end complexity. Use the I2S modules to drive an audio codec for HMI sound feedback alongside the display.

USB Audio Interface
The PIC32MX570F512L-V/PF is well suited for USB audio class devices because it combines USB 2.0 Full-Speed OTG with two I2S modules and four SPI modules for codec interfacing. The 50 MHz core delivers enough processing margin for sample-rate conversion and audio effects while maintaining a stable USB isochronous stream. The 512 KB Flash stores USB Audio class drivers and audio processing code, while 64 KB SRAM supports multi-channel audio buffering. Add an external low-jitter crystal for I2S MCLK to preserve audio dynamic range.
Được đề xuất
CAN-Based Industrial Control Node
The PIC32MX570F512L-V/PF anchors industrial control nodes on a CAN bus by integrating CAN 2.0B with DeviceNet-ready addressing and exposing the full peripheral set in a 100-pin TQFP. The 50 MHz MIPS core handles CANopen or DeviceNet stack processing while PWM, ADC, and I/O peripherals drive actuators and sensors. The AEC-Q100 grade and -40C to +105C operating range make this -V/PF variant suitable for harsh industrial cabinets. Use PPS to optimize PCB routing and isolate analog and digital grounds near the CAN transceiver.
Được đề xuất
Touch-Screen User Interface
The PIC32MX570F512L-V/PF simplifies resistive touch-screen design by integrating the CTMU for touch bias and a 10-bit ADC for position measurement, eliminating external analog front-end parts. Peripheral Pin Select remaps I/O to keep the touch layer routing clean, and PMP simultaneously drives a parallel LCD while touch scanning runs in the background. The 64 KB SRAM and 50 MHz core support lightweight GUI frameworks without external memory. Combined with the AEC-Q100 qualification, this part can serve automotive HMI prototypes as well as industrial panels.
Được đề xuất
Automotive Body Control Module
The PIC32MX570F512L-V/PF in its AEC-Q100 qualified form provides automotive body-control functionality through CAN 2.0B communication, LIN-capable UART peripherals, PWM outputs for lighting and motors, and robust ADC channels for sensor monitoring. The 100-pin TQFP exposes enough I/O for multi-load drivers while the -40C to +105C operating range tolerates under-hood thermal stress. The 512 KB Flash holds bootloader and CAN stack plus application firmware, and 64 KB SRAM buffers diagnostic messages. Pair the MCU with automotive-grade CAN transceivers and watchdog supervisors for full ISO 11898 compliance.

Ghi chú thiết kế
Operate the PIC32MX570F512L-V/PF from a regulated 3.3 V supply within 2.3 V to 3.6 V per the family datasheet. Place a 10 uF bulk capacitor near the device plus 0.1 uF decoupling on each VDD/VSS pair to suppress switching noise from USB and CAN transceivers. The USB VBUS sense pin (RPF5/USBVBUS) requires a divided-down signal of the 5 V bus, not a direct connection. A supervisor or reset circuit is recommended for applications with slow-rising power rails.
Route the USB D+/D- differential pair with 90 ohm differential impedance and keep them length-matched to within 150 mil for Full-Speed signal integrity. Keep the crystal traces short and surrounded by a ground guard to minimise jitter on the 50 MHz system clock. Place the CAN bus transceiver close to the MCU and route CANH/CANL as a twisted pair with 120 ohm termination at each end of the bus. The 100-pin TQFP benefits from a continuous ground plane beneath the part.
Do not assume all PIC32MX570F512L-V/PF variants run at 50 MHz - some -I grade parts top out at 40 MHz, so always confirm the speed suffix in the device marking. PPS mappings must be unlocked before configuration writes, or peripheral output mapping will silently fail. The CTMU is sensitive to ADC sampling time settings; insufficient acquisition time degrades touch accuracy. Finally, the -V grade (-40C to +105C) parts may be required for automotive use cases - the -I grade is industrial only.
