HT93LC46EEPROM 是Holtek 制造的1K 位系列的EEPROM（电子可擦除只读存储器），一般 它用于微控制器的固定数据的存储。在本文中，我们将以Holtek 公司8 位微控制器HT49 系列为例，介绍该芯片常用的操作功能代码。用户只需把代码加到程序中，并且在使用HT93LC46 之前将引脚CS/SK/DI/DO 连接即可。-HT93LC46EEPROM is a 1K-bit Holtek manufactured series of EEPROM (electronic erasable read-only memory), general micro-controller is used to store fixed data. In this article, we will Holtek" s 8-bit microcontroller HT49 series, for example, the introduction of the chip code commonly used operating functions. Users simply add the code the program, and before the use of HT93LC46 pin CS/SK/DI/DO connection is needed.
