PIC32MX575F256LT-80I/BG 概要
A microcontroller (MCU) is a programmable system-on-chip that combines a CPU core, memory, and peripherals to execute embedded firmware in real time. The PIC32MX family extends this concept with a 32-bit MIPS core that delivers significantly higher computational throughput than 8-bit or 16-bit MCUs, while maintaining deterministic interrupt behaviour. Within the wider taxonomy, this part belongs to: microcontroller -> 32-bit MCU -> MIPS MCU -> PIC32MX family -> USB-and-CAN enabled tier.
Key features include 256 KB (256K x 8) of in-system self-programmable Flash, 64 KB of SRAM, 53 general-purpose I/O pins, multiple UART, SPI, and I2C peripherals, and a 16-bit parallel master port for external memory or graphics interfacing. The integrated USB 2.0 full-speed transceiver supports device, host, and OTG operation, removing the need for an external PHY in many designs.
Typical applications include industrial control with CAN-bus connectivity, USB peripherals such as HID and CDC devices, graphical HMI panels using the parallel master port, embedded data loggers, and low-cost USB-to-UART bridges. The wide operating voltage of 2.5 V to 3.6 V and industrial temperature range of -40 C to +85 C suit factory-floor and outdoor installations.
When designing with this part, ensure the TFBGA-121 land pattern meets IPC-7351 ball-pitch tolerances and that decoupling is placed within 2 mm of each power ball. For new designs, also evaluate the newer PIC32MX1xx/2xx families for lower power consumption and the PIC32MK family for higher performance.

主な用途
PIC32MX575F256LT-80I/BG の用途: 6 件s: USB-to-UART Bridge Bridge, Industrial CAN-Bus Node, USB HID Peripheral (Keyboard / Mouse / Custom HID), Graphical HMI Display Controller, Data Logger with USB and CAN, Automotive-Grade CAN Gateway (AEC-Q100 context).
USB-to-UART Bridge Bridge
The PIC32MX575F256LT-80I/BG is well suited to USB-to-UART bridge designs because its 80 MHz MIPS core, 256 KB Flash, and integrated USB 2.0 full-speed device controller remove the need for an external PHY. With 64 KB of SRAM available, designers can buffer large CDC frames while running at the full 12 Mbps USB rate. The 53 GPIO pins can serve as RTS/CTS handshaking lines, multiple UART bridges, and status LEDs.
おすすめ
Industrial CAN-Bus Node
In industrial CAN-bus nodes (CANopen, DeviceNet), the PIC32MX575F256LT-80I/BG's integrated CAN 2.0B controller with 32 mailboxes and ISO 11898-1 compliance supports standard and extended identifiers at up to 1 Mbps. The 256 KB Flash holds bootloader plus CANopen stack, while 64 KB SRAM buffers protocol PDOs. The industrial -40 C to +85 C operating range and 2.3 V to 3.6 V supply cover 24 V factory-floor rails, then back to 3.3 V regulation.
おすすめ
USB HID Peripheral (Keyboard / Mouse / Custom HID)
The PIC32MX575F256LT-80I/BG handles USB HID-class devices natively: 53 GPIO pins drive keyboard matrices, mice sensors, or custom HID buttons, while 64 KB SRAM buffers HID events. Microchip's MPLAB Harmony USB HID stack supports boot-loader and runtime HID classes and runs comfortably at 80 MHz. The 121-TFBGA package supports dense PCB layouts while keeping the USB bus within 20 mm of the connector to meet USB 2.0 signal-integrity rules.
おすすめ
Graphical HMI Display Controller
For graphical HMI panels, the PIC32MX575F256LT-80I/BG's 16-bit Parallel Master Port (PMP) drives TFT LCDs up to QVGA resolution at full frame speed, while 64 KB SRAM holds the framebuffer or tile map. The 256 KB Flash accommodates large image assets and Unicode fonts. The 80 MHz MIPS core can refresh screens in parallel with USB and CAN traffic, making this part a good fit for compact industrial control panels.
おすすめ
Data Logger with USB and CAN
In embedded data loggers, the PIC32MX575F256LT-80I/BG streams ADC and CAN bus data over USB while logging to external SPI Flash. The 80 MHz MIPS core executes concurrent ADC sampling (10-bit, up to 1 Msps), CAN 2.0B reception at 500 kHz, and USB CDC transmission to a host PC. The 53 GPIO pins include enough spare I/O for SD card interfaces, RTC chips, and external SPI sensors.
おすすめ
Automotive-Grade CAN Gateway (AEC-Q100 context)
Although the PIC32MX575F256LT-80I/BG is industrial-grade, designers prototyping automotive CAN gateways can use it as a development platform before migrating to the AEC-Q100 qualified PIC32MX1xx or PIC32MX5xx automotive variants. The integrated CAN 2.0B and 80 MHz MIPS core handle OBD-II and CAN-FDbus preliminary testing. Pair it with a MCP2551 or MCP2562 CAN transceiver for full bus isolation during bench validation.

設計ノート
For the 121-TFBGA 0.8 mm ball-pitch package, follow IPC-7351 nominal land recommendations: non-solder-mask-defined (NSMD) pads are strongly recommended for modular drilling and reworkability. Place a 0.1 uF X7R decoupling capacitor within 2 mm of each VDD/VSS ball pair, and provide a continuous ground plane on the second layer to ensure low-impedance return paths for USB 2.0 full-speed signalling (12 Mbps).
Decouple the PIC32MX575F256LT-80I/BG's 2.3 V to 3.6 V supply with bulk tantalum or ceramic capacitors plus 100 nF ceramic capacitors near every VDD ball. The internal USB transceiver draws up to 50 mA during bus activity, so a low-noise LDO such as TPS217 is recommended upstream; avoid switching regulators that share the USB signal-return path. Estimate: at 80 MHz with all peripherals active, core draw current varies from a datasheet-specified range; check the latest DS61121G revision for the exact IDD figure before designing the power budget.
Do not assume JTAG pins are 5 V tolerant: they are 3.3 V only, and applying 5 V to any I/O can latch-up the part. For production programming, configure the PPS (Peripheral Pin Select) registers early in init code before configuring USB or CAN - otherwise the USB D+/D- lines will not route to the correct physical pins. Also confirm that the VBUS pin is tied to the 5 V USB VBUS through the recommended 0.1 uF decoupling per the Microchip hardware checklist.
