LPC4357FET256,551 Datasheet PDF - NXP

The LPC4357FET256,551 is a dual-core Cortex-M4 Digital Signal Controller designed for embedded applications requiring signal processing. The ARM Cortex-M4 core offers single-cycle multiply-accumulate and SIMD instructions and a hardware floating-point unit to support signal processing while the M0 coprocessor handles I/O and digital control processing. The microcontroller includes 1MB flash memory, 136kB of data memory, two high speed USB 2.0 host/OTG/devices, advanced configurable peripherals such as the state configurable timer (SCT), serial general purpose I/O (SGPIO) and SPI flash interface (SPIFI) as well as Ethernet, an external memory controller and multiple digital and analogue peripherals.

● ARM Cortex-M4 built-in nested vectored interrupt controller
