MPN: PIC32MX570F512HT-I/PT ✓ Hoạt độngPIC32MX570F512HT-I/PT Tóm tắt
A 32-bit microcontroller (MCU) is an integrated circuit that combines a 32-bit CPU core, flash program memory, SRAM data memory, and configurable peripherals on a single die, sitting above 8/16-bit MCUs in processing capability while below microprocessors in system cost. The PIC32MX family belongs to the broader category of embedded microcontrollers, which in turn are part of the power management and digital IC ecosystem used in industrial, consumer, and IoT products. Within that taxonomy, PIC32MX570 devices are positioned for USB-connected and graphics-capable embedded designs.
Key features include 83 DMIPS core performance, peripheral pin select (PPS) for flexible I/O mapping, parallel master port (PMP) with dual buffers for graphics, two I2S and four SPI modules for codec and serial communications, an integrated CTMU for capacitive touch, and a real-time clock/calendar (RTCC). The 64-pin TQFP package provides 5V-tolerant I/O on most pins and supports industrial temperature grades from -40C to +85C.
Technically, the PIC32MX570F512HT-I/PT uses a 5-stage pipeline M4K core with single-cycle multiply and hardware divide, supported by a prefetch cache that boosts flash throughput. The 40 MHz version (the -I grade) operates at 3.3V and targets cost-sensitive general-purpose embedded designs, while the 50 MHz -50I grade in the same family offers higher throughput. PPS remapping means peripherals can be assigned to most digital I/O pins, simplifying PCB routing.
Typical applications include industrial control panels, USB peripherals (HID, CDC, mass storage), embedded audio I2S bridges, CAN node interfaces, low-cost graphics displays, and capacitive touch human-machine interfaces. The integrated USB and CAN make it well-suited for industrial automation, point-of-sale terminals, and home appliances.
When designing with this part, ensure the JTAG/ICD programming header follows Microchip's recommended 4-wire or 2-wire layout and that the USB D+/D- lines include proper 90-ohm differential routing. Pin-compatibility with PIC32MX570F512H-I/PT in the same TQFP-64 footprint enables direct placement on existing boards.

Ghi chú thiết kế
Place a 0.1 uF decoupling capacitor as close as possible to every VDD pin (pins 11, 18, 28, 38, 54) and a bulk 4.7-10 uF tantalum or ceramic capacitor near the package. For USB applications, add 90-ohm differential impedance routing on the D+ and D- lines with matched length and a 90-ohm differential termination. The 64-pin TQFP exposes multiple ground pins (5, 17, 27, 37, 53, 64) which must all be connected to a continuous ground plane for signal integrity and thermal performance.
The USB D+/D- lines require 90-ohm differential impedance with matched trace lengths within 150 mils. For USB full-speed signals, route them over a continuous ground plane and avoid splits or vias. The integrated USB transceiver requires no external pull-up resistor on D+ for full-speed device mode; however, an external 1.5 kohm pull-up to 3.3V may be added if soft-connect behavior is needed during enumeration. CAN bus requires twisted-pair cabling with 120-ohm termination at both ends of the bus.
Do not exceed 3.6V on any digital I/O pin; although PIC32MX I/O is 5V tolerant on most pins, the absolute maximum on VDD is 3.6V. Ensure the MCLR pin (pin 63) has a proper reset circuit with 10 kohm pull-up to VDD and a 1 nF capacitor to ground for clean reset behavior. For PMP graphics applications, configure the PMAEN register correctly before enabling the parallel master port, otherwise the PMP bus can be left in an undefined state causing display glitches at startup.
The PIC32MX570F512HT-I/PT in TQFP-64 has a thermal resistance of approximately 70 C/W theta-JA. At maximum operating temperature of 85C, this allows for limited self-heating from core activity. Estimated: with all peripherals active at 40 MHz, typical core power is around 200 mW, yielding about 14C temperature rise above ambient - well within industrial-grade limits. For elevated-temperature applications above 70C ambient, consider the 64-pin QFN package variant (PIC32MX570F512H-50I/MR) which has lower theta-JA of approximately 28 C/W.
Route the 8 MHz primary oscillator traces (pins 39 OSC1 and 40 OSC2) as short as possible with a guard ring or ground pour on both sides. Keep the crystal traces away from high-speed digital lines such as SPI, USB, and PMP data bus signals. If using the internal 8 MHz RC oscillator instead of an external crystal, leave pins 39-40 floating or grounded. The JTAG programming pins (PGECx/PGEDx) should be brought to test points or a 2x5 header for in-circuit debugging.
