1. General description
The LPC546xx is a family of ARM Cortex-M4 based microcontrollers for embedded
applications featuring a rich peripheral set with very low power consumption and
enhanced debug features.
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 processor is integrated into the core.
The LPC546xx family includes up to 512 KB of flash, 200 KB of on-chip SRAM, up to
16 kB of EEPROM memory, a quad SPI Flash Interface (SPIFI) for expanding program
memory, one high-speed and one full-speed USB host and device controller, Ethernet
AVB, LCD controller, Smart Card Interfaces, SD/MMC, CAN FD, an External Memory
Controller (EMC), a DMIC subsystem with PDM microphone interface and I
