Microchip PIC32MX270F256DT-V/TL 32-bit Microcontroller Overview and Application Guide
The Microchip PIC32MX270F256DT-V/TL is a member of the high-performance PIC32MX family of 32-bit microcontrollers, built around the powerful MIPS32® M4K® core. This particular variant combines robust processing capabilities with a rich set of integrated peripherals, making it an ideal solution for a wide spectrum of embedded applications, from industrial control to advanced consumer devices.
Operating at up to 50 MHz, it delivers a significant performance boost over traditional 16- and 8-bit architectures, enabling the handling of complex algorithms and real-time tasks with ease. A standout feature is its 256 KB of self-programmable Flash memory and 64 KB of RAM, providing ample space for sophisticated application code and data processing. The inclusion of a Memory Protection Unit (MPU) enhances system reliability by isolating critical software processes, which is vital for applications requiring functional safety.
The peripheral set is exceptionally comprehensive. It features a 10-bit Analog-to-Digital Converter (ADC) with a throughput of up to 1 Msps, multiple UART, SPI, and I²C™ serial communication modules for connecting to a vast array of sensors and peripherals, and two 16-bit general-purpose timers/counters. Furthermore, it includes hardware support for USB 2.0 Full-Speed (Device, Host, and OTG), allowing for easy implementation of connectivity interfaces. For human-machine interface (HMI) applications, its Parallel Master Port (PMP) is highly efficient for driving graphical displays.
