Working Principle

The PIC32MX440F128LT-80V/BG is based on an architecture with a single CPU core, the MIPS M4K core. This CPU is supported by an advanced set of application-oriented peripherals, such as a USB 2.0 Host/Device controller, a 10/100 Ethernet Media Access controller (EMAC) and a CAN 2.0B interface. Additionally, the PIC32MX440F128LT-80V/BG provides 8-channel Direct Memory Access (DMA) for efficient data throughput and improved system performance.

The MIPS M4K core is a 32-bit processor with 32-bit data and address buses, provides enhanced instruction set, and a 4-stage instruction pipeline. The processor’s primary benefits include reduced code size, improved performance, and interrupt latency. The processor also supports multiple levels of interrupts, allowing the processor to handle up to 8 independent interrupt sources.

The PIC32MX440F128LT-80V/BG utilizes the Peripheral Event System (PES) to allow peripheral event triggering to occur without having to access the main processor. This allows the processor to more efficiently handle continuous operation events such as serial communication and motor control. The PES is also useful for setting up data transfer and storage operations without CPU intervention.

The PIC32MX440F128LT-80V/BG also supports a number of communication protocols, such as SPI, I2C and UART, which are used for communication with external devices. Additionally, the microcontroller includes an 8-pin Digital Input Capture (DIC) port for controlling and processing digital signals from sensors, switches, and other digital inputs. The microcontroller has a programmable pull-up and pull-down list for all input pins, allowing for the use of simple, low-power and cost-sensitive peripherals.

The PIC32MX440F128LT-80V/BG is a low-cost and low-power microcontroller designed for battery-powered applications. It is designed to run at lower voltages, allowing for extended battery life. Additionally, the PIC32MX440F128LT-80V/BG is packed with features, including an integrated flash memory, integrated RAM, an extended instruction set, and improved levels of performance and interrupt latency. This makes it an attractive option for a wide variety of applications.
