PIC32MX570F512HT-50I/PT - 50MHz 512KB Flash MCU | Microchip
The Microchip Technology PIC32MX570F512HT-50I/PT is a 32-bit MIPS32 M4K microcontroller running up to 50 MHz / 83 DMIPS, integrating 512 KB Flash and 64 KB SRAM in a 64-pin TQFP (10x10 mm) package with industrial -40C to +85C temperature grade. The 'T' suffix indicates Tape and Reel packaging, while 'HT' denotes the 64-pin TQFP package and '50I' specifies 50 MHz operation with industrial temperature range.
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and peripherals such as timers, communication interfaces, and analog blocks. The PIC32MX5xx family belongs to Microchip's PIC32 line, which combines MIPS M4K RISC architecture with rich peripheral integration, bridging 8/16-bit PIC microcontrollers and high-performance MPU-class devices. The MX570 sits in the mid-range Flash density tier (512 KB) with USB 2.0 full-speed OTG, two I2S, four SPI/I2S, PMP, and CTMU peripherals.
Key features include 50 MHz / 83 DMIPS core performance, 512 KB Flash with 64 KB RAM, 49 I/O pins with Peripheral Pin Select (PPS) remappable functions, two I2S modules for audio codecs, four SPI and four I2C interfaces, USB 2.0 full-speed OTG with dedicated DMA, a 10-bit 1 Msps ADC with 28 channels, a Parallel Master Port (PMP) with dual buffers for graphics, a Charge Time Measurement Unit (CTMU) for capacitive touch, and a 16-bit Parallel Port. Hardware multipliers/Dividers and a 5-stage pipeline execute DSP-like operations efficiently.
The architecture uses a Harvard-style 5-stage pipeline with separate instruction and data paths, plus a tightly coupled prefetch module that hides Flash latency. USB 2.0 full-speed OTG, two I2S interfaces, and PMP with dual buffers enable direct interfacing to audio CODECs, USB devices, and graphical LCDs without external logic, simplifying BOM. PPS remapping lets designers route digital functions to any GPIO pin, simplifying PCB layout and routing.
Typical applications include industrial control panels, USB-capable embedded devices (HID, CDC, MSD), audio playback modules with I2S CODECs, low-cost graphical HMI with PMP-driven LCDs, capacitive touch user interfaces using CTMU, and IoT edge nodes requiring USB connectivity. The wide peripheral set is well suited to consumer and industrial products that need USB, audio, and graphics in a single chip.
Design consideration: PPS remapping allows function-to-pin routing but each physical pin still has limited simultaneous function sets; verify the desired combination in the pin tables before committing to a pinout. For USB applications, the VBUS pin must be conditioned per the device errata and DP/DPU lines routed as a 90 ohm differential pair with proper guard traces.
This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and design considerations not found in the manufacturer datasheet, optimized for engineers selecting an MCU for USB + audio + graphics applications.
