MCHPPIC32MX270F256B-50I/SO
Overview
The PIC32MX270F256B-50I/SO is a high-performance 32-bit microcontroller featuring a MIPS32 M4K core operating at up to 50MHz. It integrates 256KB of Flash memory and 64KB of RAM, providing a capable platform for digital signal processing and complex control tasks in a 28-pin SOIC package. This device is particularly notable for its Full-speed USB 2.0 support and integrated mTouch capacitive touch sensing technology.
Why Choose This Part
The microcontroller provides 5V-tolerant digital inputs, significantly simplifying interfacing with legacy industrial logic and 5V sensors. Its MIPS32 M4K core includes dedicated DSP instructions for efficient mathematical operations, while the 64KB of RAM is generous for a 28-pin device, allowing for significant data buffering.
Applications
Getting Started
Develop applications using the MPLAB X IDE and the MPLAB XC32 Compiler. For hardware evaluation, the Microchip PIC32MX270F256B Plug-In Module (MA320014) can be used with Explorer 16/32 development boards. Debugging is typically performed via the MPLAB PICkit 4 or ICD 4 in-circuit debuggers through the integrated JTAG/ICSP interface.
