LPC4320FET100,551

LPC4320 系列 200 KB SRAM 150 MHz 32 位 表面贴装 微控制器 - TFBGA-100

Overview

The LPC4320FET100 is an ARM Cortex-M4 based digital signal controller with an ARM Cortex-M0 coprocessor 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 LPC4320FET100 includes 200 kB of data memory, one High Speed USB 2.0 Host/OTG/Device, advanced configurable peripherals such as the State Configurable Timer SCT, Serial General Purpose I/O SGPIO, and SPI Flash Interface SPIFI as well as an external memory controller and multiple digital and analog peripherals.
