LPC4320FBD144,551

The LPC4350/30/20/10 are ARM Cortex-M4 microcontrollers for embedded applications, featuring one ARM Cortex-M0 coprocessor, up to 264 kB SRAM, advanced configurable peripherals (such as the State Configurable Timer (SCT) and Serial GPIO (SGPIO) interface), two high-speed USB controllers, Ethernet, LCD, one external memory controller, and multiple digital and analog peripherals. The LPC4350/30/20/10 series operates at CPU frequencies up to 204 MHz. The ARM Cortex-M4 is a next-generation 32-bit microcontroller core offering low power consumption, ease of debug, ease of integration, and numerous other system-enhancement advantages. The ARM Cortex-M4 core CPU employs a 3-stage pipeline and Harvard architecture with separate local instruction and data buses plus a third bus for system peripherals, and also includes an internal prefetch unit supporting speculative branch operations. The ARM Cortex-M4 supports single-cycle DSP and SIMD instructions. The core integrates a hardware floating-point unit. The ARM Cortex-M0 coprocessor is a highly energy-efficient 32-bit core that is easy to use and delivers outstanding performance, with code and toolchain compatibility with the Cortex-M4. As a replacement for existing 8/16-bit microprocessors, the Cortex-M0 coprocessor delivers performance up to 204 MHz with a simple instruction set and reduced code size.
