EEPROM（电可擦除可编程只读存储器）是一种非易失性存储器芯片，应用广泛，即使断电也不会丢失数据，并且支持通过电子信号进行重新编程。通常，EEPROM用于存储对设备运行至关重要的信息，包括可能不时更新的信息，例如固件、系统本身的配置数据或用户 ...

部分MCU片内不带程序存储器ROM，可执行代码只能放在外面的EEPROM、FLASH(外扩)中； 单片机对于数据的处理和系统的大量数据采集，需要考虑数据的长期保存和掉电保存等问题，因此外扩EEPROM就是这系统常见的模块。外扩的EEPROM也可以用来存储一些参数，保存一些 ...

This application note describes how to control an external EEPROM by using the I2 C bus features. The sample code shown in this application note writes and reads 4-byte (word) data to and from the ...

There are plenty of techniques and components that we use in our everyday hardware work, for which their connection and coding is almost a done deal. We are familiar with them and have used them ...

The 24VL025 is a 2K I2C serial EEPROM. The device operates in a VCC ranging from 1.5 V to 3.6 V. It is organized as a single block of 256 x 8-bit memory with a 2-wire serial interface. Low-current ...

Over on YouTube [Electronic Wizard] explains how to use the AT24C32 EEPROM for external memory for microcontrollers. He begins by explaining that you don’t want to ...
