4 产品名称 4-Bit MCU 的一般应用 标题 TM8726 内部 RC 频率的温度测试 应用说明 该文件主要说明 TM8726 IC 工作频率在 Internal Fast

250 kHz、500 kHz,且BCF=1,在3V 和1.5V 应用上,测试温度在-40℃~+90℃时,针对 Internal Fast

250 kHz、500 kHz 的频率变化做 量测. 底下是针对 3V 和1.5V 应用,-40℃~+90℃之间,针对 Internal Fast

250 kHz 和Internal Fast

500 kHz 频率变化做测试,以25℃时所测试到的频率值做标准和其他温度测试到的频率值,取比 值(Fosc/Fosc25℃)而做出的
