PIC32MX575F512LT-80V/BG Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and a rich set of peripherals such as timers, communication controllers, and analog blocks. The PIC32MX5xx/6xx/7xx family sits within Microchip's broader PIC32 product line, which targets cost-sensitive embedded designs that need 32-bit MIPS performance but remain code-compatible with the well-known PIC16/PIC24 ecosystems. The PIC32 family itself is a hypernym under the larger 32-bit microcontroller taxonomy and ultimately falls under microcontrollers > integrated circuits > semiconductors in the electronics taxonomy.
Key features include 80 MHz core speed with 1.56 DMIPS/MHz performance, 512 KB Flash for firmware-heavy applications, 64 KB SRAM, a 10-bit ADC with up to 16 channels, plus two I2C, two SPI, and five UART interfaces. The integrated USB-OTG controller and one CAN module are distinctive for the 32-bit MCU tier at this price, enabling connected-embedded designs without external bridge ICs.
The device uses a 5-stage MIPS32 M4K pipeline and a peripheral bus clocked independently of the system clock. Memory protection and a prefetch cache accelerate Flash execution. The 121-ball TFBGA package supports high-pin-count designs while occupying only 100 mm² of board space, which is useful for compact human-machine interface (HMI) and CAN-node products.
Typical applications include industrial automation controllers, USB peripherals and device/host/OTG nodes, home appliance control boards, building-automation gateways, sensor hubs, and CAN-based automotive subsystems. Designers usually pair the MCU with the PICkit 5 in-circuit debugger and the MPLAB X IDE toolchain for code development.
When designing with this device, observe Microchip's recommended decoupling (0.1 µF plus 10 µF bulk), a proper VBAT/VDD rail sequencing strategy, and follow the TFBGA PCB layout guidelines for BGA escape routing and via-in-pad to maintain signal integrity at 80 MHz.

Design Notes
The 121-TFBGA package (10x10 mm ball pitch) requires via-in-pad PCB construction for the inner balls to escape cleanly. Recommended stack-up: 4-layer FR-4 with 0.4 mm ball pitch, microvias (0.1 mm) on inner balls and standard 0.3 mm vias on outer balls. Per Microchip TFBGA layout guidelines, ground planes under the BGA should not be removed - stitch the ground plane with a 1 mm grid of vias for thermal and EMI reasons.
Estimated: with all peripherals active at 80 MHz, the core draws approximately 70 mA from a 3.3 V supply, peaking near 100 mA during USB transactions. Decoupling must include a 10 uF bulk plus a 0.1 uF ceramic on each Vdd/Vss pair within 3 mm of the BGA balls. A ferrite bead between the USB Vbus rail and the MCU Vdd is recommended to isolate USB switching noise from the analog 3.3 V rail.
Configuration bits must be set correctly on every reset - especially the JTAGEN, FSOSCEN, and POSC_XTAL bits. The USB-OTG D+/D- traces must be 90 ohm differential with no stub branches. The CAN bus requires a 120 ohm termination at each bus end. The PLL lock time after startup is 2 ms typical - the USB stack initialization must delay until PLL is locked to avoid enumeration failures.
Compliance Information
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified - use PIC32MX automotive family for full automotive qualification. Lead-free (Pb-free) reflow compatible.
