PIC32MX575F512L-80V/PT - 80MHz 32-bit MCU 512KB Flash USB-OTG CAN | Microchip

The Microchip Technology PIC32MX575F512L-80V/PT is a 32-bit MIPS M4K microcontroller running at 80 MHz (105 DMIPS), integrating 512 KB of Flash and 64 KB of SRAM with a USB 2.0 On-The-Go peripheral and a CAN 2.0b module. It is delivered in a 100-pin TQFP (PT) package measuring 12x12x1 mm and is rated for the -40C to +105C industrial temperature range (suffix 'V'). What is a PIC32MX5xx microcontroller? It is a family of high-performance 32-bit flash microcontrollers built on the MIPS M4K core with a 5-stage Harvard pipeline and MIPS16e code compression, sitting in Microchip's PIC32 hierarchy (PIC32MX5xx -> PIC32MX -> PIC microcontrollers -> 32-bit MCU -> embedded processor). The '57x' sub-family adds full-speed USB-OTG with on-chip PHY and a hardware CAN 2.0b controller, targeting connected industrial and embedded nodes. Key features of the PIC32MX575F512L-80V/PT include the 80 MHz / 105 DMIPS core, 512 KB Flash (512K x 8), 64 KB SRAM, an integrated full-speed USB 2.0 OTG transceiver (PHY), a CAN 2.0b module with 1024 transmit/receive buffers, 4 dedicated DMA channels for USB OTG, a 10-bit 1 Msps ADC, and 85 I/O-capable pins on the 100-pin package. The MIPS16e instruction mode compresses code by up to 40%, effectively enlarging the usable Flash density. Architecturally, the device pairs a 5-stage Harvard pipeline (32-bit MIPS M4K) with separate Flash and SRAM buses, allowing simultaneous instruction fetch and data access. Dedicated DMA channels offload USB-OTG data movement from the core, freeing CPU cycles for application logic and ensuring deterministic USB throughput under heavy bus traffic. Typical applications include USB-enabled industrial controllers, CAN-connected automotive body and diagnostics modules, embedded data loggers, USB peripherals such as human-interface devices, and small graphics/HMI front-ends that benefit from the large Flash budget. Designers choose this part when they need both USB-OTG and CAN in a single 32-bit MCU without external PHY or transceiver ICs. When designing with this part, ensure the USB DP/DM traces are 90-ohm differential-controlled-impedance and kept under 50 mm, and provide an external 12 MHz crystal plus the correct PLL configuration to derive the 80 MHz system clock. The CAN bus requires an external transceiver (e.g., MCP2551) because the on-chip CAN module is protocol-only.

PIC32MX575F512LT-80I/BG

PIC32MX575F512LT-80I/BG - 80MHz 512KB Flash 32-bit MCU | Microchip

The Microchip Technology PIC32MX575F512LT-80I/BG is a 32-bit MIPS32 M4K PIC microcontroller running up to 80 MHz with 512 KB of Flash program memory and 64 KB SRAM, housed in a 121-ball TFBGA package measuring 10x10 mm with 0.8 mm ball pitch. A microcontroller is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), and a rich set of peripherals (UART, SPI, I2C, USB, CAN, timers, ADC) onto one die. The PIC32MX5/6/7 family sits in the 32-bit MCU category above 8-bit/16-bit MCUs and below Cortex-M-class application processors, targeting connected embedded designs that need strong peripheral integration. Within that family, the 575 sub-family adds USB 2.0 Full-Speed OTG, a CAN 2.0B controller, and an Ethernet MAC on top of the baseline PIC32MX5 peripheral set. Key features include 80 MHz core clock with 1.56 DMIPS/MHz (M4K core), 512 KB Flash, 64 KB SRAM, USB 2.0 Full-Speed OTG, one CAN 2.0B controller, 10/100 Ethernet MAC, five 16-bit timers/capture/compare, a 10-bit 1 Msps ADC with up to 16 channels, four UART, three SPI, and two I2C ports, plus a Parallel Master Port for external bus peripherals. Industrial temperature range -40C to +85C and 2.5V/3.3V operation make it suitable for connected industrial nodes. The M4K core uses a 5-stage pipeline with Harvard architecture and a hardware multiply/divide unit. The 121-ball TFBGA package uses a 0.8 mm pitch that requires NSMD or SMD pads, controlled-impedance Ethernet traces, and bulk ceramic + tantalum decoupling on VDD/VUSB/VPLL rails. Compared with bare-metal Cortex-M0/M0+ parts at similar price points, the PIC32MX575F512L adds integrated USB, CAN and Ethernet in a single die, reducing BOM cost for connected-node designs. Typical applications include USB peripherals, CAN-connected industrial controllers, Ethernet-enabled embedded web servers, audio consumer devices, and full-color HMI/graphical embedded applications. It is a strong fit for designs that must combine USB device/host connectivity with CAN-based fieldbus or 10/100 Ethernet on a single chip. When designing with this MCU, allocate enough PCB real estate for the 0.8 mm pitch BGA fanout (microvia recommended). The PLL requires a clean low-jitter 8 MHz fundamental crystal with load capacitors matched to the crystal CL, and a ferrite bead on VDDCORE is required for stable operation across the industrial -40C to +85C range. A 10 uF bulk plus 0.1 uF per-pin decoupling pattern is recommended. This page synthesizes distributor pricing, drop-in alternatives within the PIC32MX5/6/7 family, and practical design notes not found in the manufacturer datasheet, giving buyers and design engineers a faster path to a validated BOM and a working board.

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.

PIC32MX575F512LT-80V/PF

PIC32MX575F512LT-80V/PF - 80MHz 32-bit MCU 512KB Flash | Microchip

The Microchip Technology PIC32MX575F512LT-80V/PF is a high-performance 32-bit MIPS32 M4K microcontroller running at up to 80 MHz, equipped with 512 KB of Flash and 64 KB of SRAM, and housed in a 100-pin TQFP (14x14 mm) package. It integrates a USB-OTG full-speed controller, two CAN modules, and a 10-bit ADC, making it a single-chip solution for connected embedded designs. The 'T' suffix denotes tape-and-reel packaging and '80V' denotes the 80 MHz speed grade with the commercial/extended voltage range, while 'PF' denotes the 100-pin TQFP package. A PIC32MX microcontroller is a MIPS-based 32-bit MCU from Microchip that bridges the gap between the 8/16-bit PIC families and higher-performance ARM Cortex-M parts. In the broader taxonomy: PIC32MX -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor. The M4K core offers single-cycle multiply and divide, hardware multiply-accumulate, and a 5-stage pipeline, giving roughly 1.5 DMIPS/MHz - significantly more headroom than legacy PIC16/PIC24 devices for DSP-style filtering, USB stacks, and graphical user interfaces. Key features of the PIC32MX575F512LT-80V/PF include 512 KB Flash, 64 KB SRAM, 80 MHz core clock, USB-OTG full-speed with on-chip transceiver, dual CAN 2.0B controllers, a 10-bit 1 Msps ADC with up to 16 channels, four SPI/I2S, five I2C, six UART modules, five 16-bit timers, eight-channel DMA, and parallel master port (PMP) for graphics or external memory. The 100-pin TQFP footprint exposes the maximum peripheral count of the family, supporting simultaneous Ethernet MAC + USB + dual CAN in industrial networking designs. The architecture uses separate 32-bit instruction and data paths (Harvard) with a tightly-coupled prefetch module that hides Flash latency, enabling zero-wait-state execution at 80 MHz from on-chip memory. Hardware interrupt controller with 5-cycle latency supports deterministic real-time response, and a Fail-Safe Clock Monitor (FSCM) detects primary oscillator failure and switches to the internal 8 MHz FRC backup. The integrated 3.3V core runs from a 2.3V to 3.6V supply, simplifying designs powered from USB bus or industrial 24V-bus-derived rails. Typical applications include industrial CAN nodes (e.g., CANopen/J1939 gateways), USB-OTG peripherals (mass storage, HID, CDC), point-of-sale terminals, motor control FOC drives, building automation controllers, and medical instrumentation requiring USB connectivity. The 10-bit ADC is adequate for non-precision sensor reading, while the dual CAN bus lets the MCU serve as a bridge between automotive/industrial segments. When designing with this device, reserve a 12 KB Boot Flash region for a USB bootloader, place a 32.768 kHz crystal on SOSCO/SOSCI if RTC accuracy is required, and add a 1uF + 100nF decoupling pair at every VDD/VSS pin pair. Use the parallel master port (PMP) for LCD interfacing up to QVGA resolution without an external graphics controller.

A 32-bit microcontroller (MCU) is a single-chip computer that integrates a high-performance processor core, program and data memory, and programmable peripherals around a unified system bus. Within the broader semiconductor taxonomy, MCUs belong to the integrated circuits family, and 32-bit variants such as the PIC32MX sit above 8-bit and 16-bit microcontrollers in processing performance while retaining deterministic real-time behavior. The PIC32MX6xx sub-family specifically targets USB- and Ethernet-connected embedded designs where on-chip connectivity peripherals eliminate the need for external PHY or MAC chips. Key differentiating features of this part include the integrated USB 2.0 On-The-Go transceiver with PHY, a 10/100 Mbps Ethernet MAC with MII/RMII interfaces, the MIPS16e code-compression mode that reduces code size up to 40 percent, a 5-stage pipelined Harvard architecture, and four DMA channels optimized for USB OTG throughput.

PIC32MX664F128LT-I/BG - 80MHz 128KB Flash MCU with USB/Ethernet
PIC32MX664F128LT-I/BG

PIC32MX664F128LT-I/BG - 80MHz 128KB Flash MCU with USB/Ethernet

The Microchip Technology PIC32MX664F128LT-I/BG is a 32-bit MIPS MCU from the PIC32MX5/6/7 family, integrating 128 KB Flash and 32 KB SRAM with a MIPS32 M4K processor core running up to 80 MHz. The device integrates a 10/100 Mbit Ethernet MAC, USB Full-Speed (USB 2.0 FS) controller, 4-channel DMA, and a rich peripheral set in a 121-ball TFBGA (10x10x1.2 mm) surface-mount package. The part is qualified to Microchip's industrial temperature range (-40C to +85C). A 32-bit microcontroller is a single-chip computer that integrates a CPU core, program Flash, data SRAM, and a peripheral set on one die. The PIC32 family uses the MIPS32 M4K core, which executes the MIPS instruction set with single-cycle multiply and hardware debug support. Compared with 8-bit and 16-bit MCUs, 32-bit devices offer higher code density, faster arithmetic, and larger address spaces - making them suitable for embedded connectivity stacks such as TCP/IP and USB. The PIC32MX664 specifically targets connected applications by integrating Ethernet and USB peripherals alongside general-purpose I/O. Key features include 53 general-purpose I/O pins organized across multiple ports, five 16-bit timers/counters, two I2C and two SPI/I2S interfaces, two comparators, a 16-channel 10-bit ADC, and a 4-channel DMA engine that offloads memory-to-peripheral transfers. The internal 8 MHz and 32 kHz oscillators reduce BOM cost by eliminating external crystals in non-precision applications. The part supports in-circuit serial programming (ICSP) and JTAG debugging through the same pins. Typical applications include industrial Ethernet nodes, USB peripherals and embedded hosts, graphical user interfaces with integrated TFT drivers, automotive infotainment subsystems, point-of-sale terminals, and home-automation gateways. The integrated Ethernet MAC with MII/RMII interfaces allows direct connection to a PHY without an external controller, while the USB Full-Speed controller can operate in either device or host mode with on-chip transceivers. When designing with this device, ensure your PCB layout follows Microchip's TFBGA routing guidelines - the 0.8 mm pitch requires laser-via or microvia fanout for production-grade reliability. Decoupling capacitors must be placed as close as possible to every VDD/VSS pair, and the analog supply (AVDD) requires an additional LC filter. Developers typically use the MPLAB Harmony framework or MPLAB XC32 compiler for firmware development, with the PICkit or ICD debugger for in-circuit debug.

PIC32MX664F128LT-I/PT - 80MHz 32-bit MCU 128KB Flash USB Ethernet | Microchip

The Microchip Technology PIC32MX664F128LT-I/PT is a 32-bit MIPS M4K microcontroller delivering 80 MHz CPU performance with 128 KB Flash and 32 KB SRAM, housed in a 100-pin TQFP package (12x12x1 mm). It integrates USB 2.0 Full-Speed OTG, 10/100 Ethernet MAC, a 10-bit 1 Msps ADC, four DMA channels, and 83 general-purpose I/O lines, making it one of the most connectivity-rich members of the PIC32MX5xx/6xx/7xx family. A 32-bit MCU is a microprocessor core that processes 32-bit data words in a single instruction, providing roughly 4x the throughput of an 8-bit or 16-bit MCU at the same clock rate. PIC32MX devices sit in the middle of Microchip's 32-bit portfolio - above the SAM D20 Cortex-M0+ entry family in performance and below the SAM E70/SAMS70 Cortex-M7 in compute. They target connected embedded applications where Ethernet, USB, or CAN connectivity is required alongside real-time control and low BOM cost. The PIC32MX664F128LT-I/PT is built on a 5-stage pipelined MIPS32 M4K core with single-cycle hardware multiply and hardware divide. It features a 16-channel 10-bit ADC with up to 16 Msps total throughput across the channels, four dedicated DMA channels that offload data movement from the CPU, and a 16-bit Parallel Master Port for external bus expansion. The 'L' suffix denotes the 100-pin TQFP package; 'I' denotes the industrial -40C to +85C temperature range; 'T' denotes tape-and-reel packaging. Typical applications include industrial Ethernet gateways, USB device and host controllers, barcode scanners, point-of-sale terminals, building automation, and embedded web servers. The combination of full-speed USB OTG and Ethernet MAC in a single 80 MHz MCU is the key differentiator against cost-down PIC32MX1xx/2xx variants and against Microchip's own Cortex-M0+ based SAM D20/D21. When designing with this device, allocate sufficient decoupling on the 2.5V internal regulator pin (pin 56/100) - Microchip recommends a 10 uF tantalum or ceramic plus a 0.1 uF bypass on VCAP. The Ethernet MAC requires an external PHY and magnetics; the USB OTG transceiver requires external 15 k pull-downs on D+/D-.

The PIC32MX5/6/7 series combines a high-performance MIPS32 M4K core with industry-leading connectivity peripherals (Ethernet, USB OTG, CAN) that allow embedded designs to add wired networking and USB device/host/OTG functionality without an external PHY companion. The M4K core executes most instructions in a single cycle and supports the MIPS16e code-compression ISA to maximise code density from the on-chip Flash. Key specifications for this part include 128 KB Flash program memory organised as 128K x 8, 32 KB SRAM, 80 MHz maximum CPU clock, an integrated 10-bit ADC with up to 16 channels and 1 Msps conversion rate, a 10/100 Mbps Ethernet MAC, USB 2.0 OTG controller with on-chip transceiver, up to 83 programmable I/O pins, and 5 timer/counters. The 121-TFBGA (10x10 mm) package is suited to compact, high-density layouts but requires careful PCB design for the 0.8 mm ball pitch. Architecturally, the PIC32MX664F128L combines a Harvard-style bus with a unified 32-bit data path, DMA controller for peripheral transfers, and a peripheral pin-select (PPS) engine that remaps digital peripherals to a wide choice of I/O pins, easing board layout. The USB OTG controller includes an integrated physical-layer transceiver, eliminating the need for an external PHY and reducing BOM cost for USB device, host and On-The-Go designs. Typical applications include industrial Ethernet nodes, USB human-interface devices, building-automation controllers, embedded web servers, and consumer audio accessories. The combination of Ethernet and USB OTG makes this part especially attractive for gateways that bridge USB peripherals onto an IP network. Designers should leverage the MPLAB Harmony software framework and the PIC32MX USB and Ethernet libraries to accelerate firmware development, and verify PCB escape routing for the 0.8 mm BGA balls with manufacturer-recommended design rules.
