LPC54616J512BD208E

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 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), Secure Hash Algorithm (SHA), 12 - bit 5.0 Msamples/sec ADC, and a temperature sensor.
