The LPC5460x 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 LPC5460x 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 I2S， five general-purpose timers， SCTimer/PWM， RTC/alarm timer， Multi-Rate Timer （MRT）， a Windowed Watchdog Timer （WWDT）， ten flexible serial communication peripherals （USART， SPI， I2S， I2C interface）， 12-bit 5.0 Msamples/sec ADC， temperature sensor.
