At the core of this microcontroller is the high-performance MIPS32® M4K® core, capable of operating at up to 50 MHz. This processor core offers a significant performance boost over traditional 8-bit and 16-bit MCUs, enabling the handling of more complex algorithms and tasks. It features a five-stage pipeline for efficient instruction execution and delivers 1.56 DMIPS/MHz, ensuring responsive and deterministic operation for real-time control applications.
A key attribute of the PIC32MX254F128DT-V/PT is its integrated memory configuration. It is equipped with 128 KB of high-speed Flash program memory and 32 KB of SRAM data memory. This substantial memory space provides ample room for sophisticated application code and data processing, supporting complex firmware without the immediate need for external memory components, thereby simplifying board design and reducing system cost.
The peripheral set of this MCU is exceptionally rich, designed to interface with a vast array of sensors, actuators, and communication modules. Notable peripherals include:
Dual PMP/PSP Modules: A Parallel Master/Port facilitates easy connection to external parallel devices, such as graphic LCDs or SRAM, with programmable bus timing.
Multiple Serial Communication Modules: It includes UART, SPI, and I2C™ modules, providing versatile options for asynchronous and synchronous serial communication with peripherals like sensors, wireless modules, and other microcontrollers.
10-bit ADC: A fast, 10-bit Analog-to-Digital Converter with up to 13 input channels allows for precise acquisition of analog signals from the environment.
Dual Comparators: Integrated analog comparators offer quick response to external analog conditions without CPU intervention.
Hardware Timers/Counters: Multiple 16-bit and 32-bit timers, including a real-time clock and calendar (RTCC), provide precise timing, waveform generation, and capture/compare capabilities.
The "DT" in its part number signifies that this device is offered in a 100-pin TQFP package. This package offers a high number of I/O pins (up to 85) while maintaining a relatively compact footprint, suitable for designs requiring a dense interface with external components.
Furthermore, the microcontroller incorporates advanced features for robust operation. It includes a configurable Watchdog Timer and a Programmable Brown-out Reset module to enhance system reliability in electrically noisy environments. Its flexible clocking options, including support for primary and secondary oscillators and an internal 8 MHz RC oscillator, contribute to both performance and power management strategies.
ICGOOODFIND: The Microchip PIC32MX254F128DT-V/PT is a highly capable 32-bit microcontroller that strikes an excellent balance between processing power, extensive integrated peripherals, and memory resources. Its MIPS32 M4K core and rich feature set, including parallel and serial communication interfaces, make it an ideal choice for developers migrating from 8/16-bit architectures or designing complex embedded systems that require real-time performance, connectivity, and reliable control in a single-chip solution.
