PIC32MX270F256BT-I/ML

Microcontrollers Overview

The PIC32MX270F256BT-I/ML is a 32-bit microcontroller from the PIC32MX2xx family, utilizing the MIPS32 M4K core. It features 256 KB of Flash program memory and 64 KB of SRAM data memory. The device operates at clock frequencies up to 50 MHz within an industrial temperature range of -40°C to +85°C, powered by a 2.3V to 3.6V supply. It includes a 10-bit ADC with up to 13 channels, USB 2.0 Full-speed OTG controller, multiple communication interfaces including UART, SPI, and I2C, and supports Peripheral Pin Select (PPS) for flexible pin mapping.

Microcontrollers Feature Summary

• MIPS32 M4K core providing code-efficient architecture with single-cycle multiply capabilities
• Integrated USB 2.0-compliant Full-speed On-The-Go (OTG) controller
• Advanced analog features including 10-bit ADC and Charge Time Measurement Unit (CTMU)
• Flexible peripheral configuration via Peripheral Pin Select (PPS) remapping

Microcontrollers Applications

• Bluetooth Serial Port Profile (SPP) development platforms
• USB-enabled embedded applications
• General-purpose microcontroller systems requiring audio or graphics interfaces

Microcontrollers Procurement Notes

Verify the specific ordering suffix 'BT' against official Microchip documentation to confirm tape-and-reel packaging status. Ensure the 'I' suffix matches the required -40°C to +85°C industrial temperature rating. Cross-reference the package type 'ML' with the datasheet to confirm QFN-44 physical dimensions and pinout compatibility with your PCB footprint.

Microcontrollers Selection Notes

Select this component when a balance of high-performance 32-bit processing and integrated connectivity is required. The 256 KB Flash and 64 KB RAM support complex firmware and data handling. The inclusion of USB OTG and advanced analog peripherals makes it suitable for devices needing direct host/device interaction and sensor interfacing without external components.

Microcontrollers Part Context

This part belongs to the PIC32MX1XX/2XX family, which offers 28, 36, and 44-pin options. The MX2xx series specifically distinguishes itself by including USB On-The-Go capabilities, unlike the general-purpose MX1xx series. It shares the same MIPS32 M4K core and peripheral set as other members in the 44-pin QFN package category.

Microcontrollers Replacement Considerations

Check for other PIC32MX270 variants with different packages (e.g., TQFP or VTLA) if pin count compatibility allows. Verify that alternative parts maintain the same 50 MHz speed grade and industrial temperature range.
