PIC32MX575F256L-80I/BG Présentation
A PIC32MX microcontroller is a high-performance 32-bit Flash MCU family from Microchip built on the MIPS32 M4K core, designed for embedded applications requiring USB, CAN, and Ethernet connectivity. The PIC32MX5xx/6xx/7xx sub-family sits between the lower-pin-count PIC32MX1/2/3/4/5 series and the higher-end PIC32MX7xx graphics-enabled parts, targeting connected-embedded designs that need rich peripherals and moderate code/data density. Architecturally, the PIC32MX570/575/675/795 line bridges 8-bit PIC migration paths and full Linux-capable processors.
Key features include 256 KB Flash program memory, 64 KB SRAM, full-speed USB 2.0 device/host/OTG, one CAN 2.0B controller, 10/100 Mbps Ethernet MAC, up to 83 general-purpose I/O pins, five 16-bit timers/counters, sixteen 10-bit ADC channels at 1 Msps, and two analog comparators. The 121-ball TFBGA package provides high pin density at 0.8 mm pitch with a compact 10x10 mm footprint for space-constrained designs. Industrial temperature range (-40C to +85C) is supported.
The PIC32MX575F256L uses the MIPS32 M4K core with 5-stage pipeline, single-cycle multiply, hardware multiply-accumulate, and an 8-deep prefetch cache. Peripheral bus and instruction RAM are tightly coupled to allow deterministic interrupt response, while the DMA controller with eight channels offloads data movement between peripherals and memory for streaming USB, CAN, and Ethernet traffic.
Typical applications include USB peripherals, CAN-based industrial nodes, Ethernet-connected embedded devices, industrial control and HMI, point-of-sale terminals, and medical instrumentation. The combination of full-speed USB, CAN, and 10/100 Ethernet makes the PIC32MX575F256L well suited to multi-protocol gateway designs.
When designing, plan for 2.5V/3.3V core operation, follow Microchip's TFBGA PCB layout and decoupling guidelines for high-pin-count BGA packages, and allocate sufficient code space for the TCP/IP stack (e.g., Microchip Harmony) when Ethernet is used. The pre-fetch cache must be enabled for code in flash to achieve 80 MHz performance.

Applications typiques
PIC32MX575F256L-80I/BG convient pour 6 applications: USB Peripherals and HID Devices, CAN-Based Industrial Nodes, Ethernet-Connected Embedded Gateways, Industrial Control and HMI, Point-of-Sale Terminals, Medical Instrumentation.
USB Peripherals and HID Devices
The PIC32MX575F256L-80I/BG is well suited for USB peripherals thanks to its integrated USB 2.0 Full-Speed device/host/OTG controller and 256 KB Flash for USB stacks. With 83 GPIO, the MCU can drive multi-function HID interfaces while the dedicated DMA channels offload endpoint traffic from the core. The industrial -40C to +85C range covers consumer and industrial USB dongles, custom HID input devices, and USB-to-UART bridges. Compared with PIC16/PIC24 alternatives, the 80 MHz MIPS core delivers 1.5 DMIPS/MHz, enough headroom for USB CDC plus command parsing.
Recommandé
CAN-Based Industrial Nodes
Industrial field nodes using CAN 2.0B benefit from the PIC32MX575F256L-80I/BG's integrated CAN controller, 16-channel 10-bit ADC at 1 Msps, and 256 KB Flash for CANopen or DeviceNet application layers. The 83 GPIO can drive relay drivers, opto-isolated inputs, and status LEDs without external expanders. The 5-stage MIPS pipeline at 80 MHz handles deterministic CAN scheduling alongside application logic, and the industrial temperature rating supports factory-floor deployment. Firmware libraries such as MPLAB Harmony include certified CAN stacks that fit within the 256 KB Flash budget.
Recommandé
Ethernet-Connected Embedded Gateways
The PIC32MX575F256L-80I/BG's on-chip 10/100 Mbps Ethernet MAC combined with 256 KB Flash and 64 KB SRAM is ideal for compact protocol gateways translating between Ethernet, CAN, and USB. Microchip's TCP/IP stack with lwIP integration fits within the 256 KB Flash for HTTP/MQTT/SNMP servers. The high GPIO count allows direct connection of multiple sensor buses without external I/O expanders. The 121-ball TFBGA exposes both Ethernet MII/RMII pins and the full USB OTG bus, enabling gateway designs that need wired and wireless backhaul options.
Recommandé
Industrial Control and HMI
For industrial control panels and HMI, the PIC32MX575F256L-80I/BG drives TFT displays via its parallel master port, samples analog inputs through the 16-channel 10-bit ADC, and communicates upstream over Ethernet or CAN. The 80 MHz MIPS core supports graphic libraries such as MPLAB Harmony Graphics for menus and gauges. The 121-ball TFBGA package exposes the full peripheral set required for backlit displays, keypads, and rotary encoders. Industrial temperature rating and surface-mount reliability suit factory-floor and outdoor cabinet environments.
Recommandé
Point-of-Sale Terminals
POS terminals integrate USB peripherals, Ethernet for payment gateways, and sometimes CAN or RS-485 for peripheral interconnect, all of which the PIC32MX575F256L-80I/BG supports natively. The 256 KB Flash and 64 KB SRAM are sufficient to embed TLS-capable payment client libraries and printer drivers. The 83 GPIO drives keypads, displays, card readers, and thermal printers. The surface-mount TFBGA package supports the vibration and thermal cycling demands of retail terminal housings.
Recommandé
Medical Instrumentation
Portable medical instruments use the PIC32MX575F256L-80I/BG for its low-power 2.5V/3.3V operation, integrated ADC, USB device interface, and 256 KB Flash for safety-critical application code. The 80 MHz core enables DSP-style signal processing for ECG, pulse oximetry, or glucose meter firmware. The 121-ball TFBGA provides enough GPIO for LCD, keypad, audio buzzer, and sensor interfaces while keeping board area small. Engineers pair this MCU with Class II isolation and IEC 60601-1 compliant power for bedside and ambulatory devices.

Principaux différenciateurs
- Triple-protocol connectivity in a single BGA (vs PIC32MX360F256L-80I/BG)
- 256 KB Flash vs 128 KB at the same BGA footprint (vs PIC32MX564F128L-I/BG)
- Same-family drop-in for extended temperature (vs PIC32MX575F256L-V/BG)
Notes de conception
Estimated: For the 121-ball TFBGA at 0.8 mm pitch, Microchip recommends a 0.4 mm via-in-pad array with 0.6 mm solder mask-defined pads on at least 4 routing layers to break out all signals. Place a continuous VDD-to-VSS decoupling pair (0.1 uF X7R + 4.7 uF X5R) within 5 mm of every supply ball, and use an unbroken ground plane on layer 2 to provide return paths for the 80 MHz core and USB differential pair.
The PIC32MX575F256L-80I/BG requires a 2.5V or 3.3V digital supply (range 2.3V-3.6V) plus an analog supply AVDD with separate ferrite filtering. The VCAP pin must be tied to a 10 uF low-ESR ceramic capacitor to ground for the internal 1.8V core regulator. Power-on reset and brown-out reset trip points should be left at default unless battery-backed operation is required; raise BOR to avoid resets during USB enumeration voltage dips.
Estimated: Code running from Flash at 80 MHz needs the prefetch cache module enabled (CFGCON.PREFEN = 0 or 1) - omitting this halves effective throughput. For USB, the 48 MHz USB clock must derive from the primary oscillator with PLL configured for 96 MHz / 2; using the internal 8 MHz FRC without PLL trimming causes USB compliance failures. The JTAG pins PGED1/PGEC1 (RB0/RB1) must be left as digital inputs at reset or boundary-scan may assert unexpectedly on first power-up.
Estimated: The 50 MHz USB DP/DM pair must be routed as a 90 ohm differential with no splits, a continuous ground reference, and length-matched to within 150 mils. The Ethernet MII/RMII signals to the external PHY should be routed on the top layer only, kept under 50 mm, and matched to within 100 mils; place the PHY within 25 mm of the MCU balls to avoid reflections and EMC issues.
