R3112x SERIES
LOW VOLTAGE DETECTOR WITH OUTPUT DELAY
NO. EA-087-090422
OUTLINE
The R3112x Series are CMOS-based voltage detector ICs with high detector threshold accuracy and ultra-low
supply current, which can be operated at an extremely low voltage and is used for system reset as an example.
Each of these ICs consists of a voltage reference unit, a comparator, resistor net for detector threshold setting,
an output driver, a hysteresis circuit, and an output delay circuit. The detector threshold is fixed with high
accuracy internally and does not require any adjustment. Two output types, Nch open drain type and CMOS type
are available.
Three types of packages, SOT-23-5, small SC-82AB, SC-88A and ultra-small SON1612-6 can be selected so
that high density mounting on boards is possible.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field. The functional operation at or over these absolute maximum ratings is not assured.

RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the
recommended operating conditions, even if when they are used over such conditions by momentary
electronic noise or surge. And the semiconductor devices may receive serious damage when they continue
to operate over the recommended operating conditions.

关于低通滤波,怎么把PDM信号还原成声音信号?
本帖最后由littleshrimp于2015-3-208:35编辑 想读取一个PDM麦克风数据,但是又不会DSP,想使用单片机读取然后使用PC做低通滤波,把声音还原。 现在我已经把一个PDM(脉冲密度调制)信号转换成对应的2进制流,准备把每秒2.4M的0、1数据每32位相加存到一个字节数组里,得到每秒75K字节的数据,通过USB发送到电脑,在电脑里实现滤波,因为对低通滤波方面一窍不通,不知道应该如何下手,有明白原理的,能否指点一下?我曾想过这么做,比如想得到一个16位,32.5...

也来说说我的嵌入式入门感想
不断看到有网友在论坛发帖问学习嵌入式如何入门. 个人觉得,主要还是要看个人的兴趣,看你想向偏软方向还是偏硬方向发展了 向偏软方向的话建议首先看好C,注意这个看好C,不是指语法层面的,基本的C语言语法相信一般都没任何问题了.更重要的是C的编译器是怎么工作地,一个程序编译好后,各项资源是怎么分配的,堆栈是怎么分配的,以及连接器是怎么工作的等等等等,因为做嵌入式是直接和硬件打交道,所以需要明白自己写的程序是放在内存的哪里的,运行时各种变量是放在哪的,堆栈是放在哪的,大约要使用多少堆栈...
