PIC32MX270F256B
Microchip PIC32MX270F256B 32-bit MIPS M4K MCU, 256 KB flash and 64 KB SRAM, 50 MHz, USB, in a 28-pin package.
The PIC32MX270F256B is a Microchip 32-bit microcontroller based on the MIPS32 M4K core with the MIPS16e mode for a smaller code size, in a 28-pin package. It runs up to 50 MHz and reaches about 83 DMIPS, with 256 KB of flash program memory (plus a small boot flash) and 64 KB of SRAM, which suits a higher-performance embedded application that still needs a small pin count. The device offers a USB interface, peripheral pin select for flexible I/O mapping, a parallel master port for a graphics or a memory interface, two SPI/I2S modules, and support for capacitive touch, and it operates from about 2.3 V to 3.6 V over a temperature range of -40 °C to +105 °C, with several power-management modes. The MIPS32 M4K core and the MIPS16e mode give a good performance per MHz with a compact code, and the pin compatibility with many Microchip 16-bit devices eases a migration. Typical applications include industrial control, instrumentation, audio, USB peripherals, touch interfaces and motor control that need a 32-bit core in a small package. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the memory and the package and plan the core and the peripherals.
FAE Professional Review
The PIC32MX270F256B brings a 32-bit MIPS core at 50 MHz into a 28-pin package, with 256 KB of flash and USB, so it suits a design that needs the performance of a 32-bit core without a large board. The peripheral pin select and the parallel master port add flexibility, and the MIPS16e mode keeps the code compact. Confirm the supply and the thermal range for the application.

Frequently Asked Questions
What projects suit the PIC32MX270F256B?
It suits a design that needs a 32-bit MIPS core at 50 MHz, 256 KB of flash and USB in a small 28-pin package, such as an instrument, an audio device or a touch interface. The peripheral pin select eases the I/O mapping.
Confirm the supply and the thermal range.
Why choose a 32-bit PIC here?
Choose the 32-bit PIC32 when the workload needs more memory, a higher throughput or a larger address space than an 8-bit part can provide, while keeping a small package. The MIPS core and the MIPS16e mode give a good performance with a compact code.
Our FAE team can help choose the core.
