LPC54114J256UK49: Low Power 32-bit Microcontroller based on ARM® Cortex®-M4
The LPC5411x are ARM Cortex-M4 based microcontrollers for embedded applications.These devices include an ARM Cortex-M0+ coprocessor, up to 192 KB of on-chip SRAM, up to 256 KB on-chip flash, full-speed USB device interface with Crystal-less operation, a DMIC subsystem with PDM microphone interface and I²S, five general-purpose timers, one SCTimer/PWM, one RTC/alarm timer, one 24-bit Multi-Rate Timer (MRT), a Windowed Watchdog Timer (WWDT), eight flexible serial communication peripherals (each of which can be a USART, SPI, or I²C interface), and one 12-bit 5.0 Msamples/sec ADC, and a temperature sensor.
The ARM Cortex-M4 is a 32-bit core that offers system enhancements such as low power consumption, enhanced debug features, and a high level of support block integration. The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals, and includes an internal prefetch unit that supports speculative branching. The ARM Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A hardware floating-point unit is integrated in the core.
The ARM Cortex-M0+ coprocessor is an energy-efficient and easy-to-use 32-bit core which is code and tool-compatible with the Cortex-M4 core. The Cortex-M0+ coprocessor offers up to 100 MHz performance with a simple instruction set and reduced code size.
