The LPC5410x are ARM Cortex-M4F based microcontrollers for embedded applications.These devices include an optional ARM Cortex-M0+ coprocessor, 104 KB of on-chip SRAM, 512 KB on-chip flash, five general-purpose timers, one State-Configurable Timer with PWM capabilities (SCTimer/PWM), one RTC/alarm timer, one 24-bit Multi-Rate Timer (MRT), a Windowed Watchdog Timer (WWDT), four USARTs, two SPIs, three Fast-mode plus I2C-bus interfaces with high-speed slave mode, and one 12-bit 4.8 Msamples/sec ADC.
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. The Cortex-M4F is the Cortex-M4 with the inclusion of the 32-bit Floating Point Unit. 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-M4F core. The Cortex-M0+coprocessor offers up to 100 MHz performance with a simple instruction set and reduced code size.
LPC5410x主要特性和优势:
Dual processor cores: ARM Cortex-M4 and ARM Cortex-M0+. The M0+ core runs at the same frequency as the M4 core. Both cores operate up to a maximum frequency of 100 MHz.
ARM Cortex-M4F core (version r0p1):
ARM Cortex-M4 processor, running at a frequency of up ...
