128MHz，集成高达64KB片内加密存储Flash，并支持多用户分区权限管理，支持16KB 的嵌入式 SRAM。内置一个内部高速 AHB 总线，两个低速外设时钟总线 APB 及总线矩阵，支持40个可复用 I/Os，提供丰富的高性能模拟接口，包括1个12位 4.7Msps ADC，支持16个外部输入通道和3个内部通道，同时提供多种数字通信接口，包括 4个U(S)ART、2个I2C、2个SPI/I2S、1个CAN 2.0B通信接口。N32G430C8L7 微控制器产品可稳定工作于-40°C 至+105°C的温度范围，供电电压2.4V至3.6V，提供多种功耗模式供用。<br>本次案例使用的资源不多，使用内部的时钟已经开源满足设计需求，所以无需外接时钟电路。需要注意的是芯片的每个电源的引脚都需要额外接一个100nF的外接的滤波电容，芯片的1脚需要额外接4.7uf的滤波电容。</p> <p class="paragraph text-align-type-left pap-line-1.3
