Description:
The Microchip Technology Inc. 24C02C is a 2K bit Serial Electrically Erasable PROM with a voltage range of 4.5V to 5.5V. The device is organized as a single block of 256 x 8-bit memory with a 2-wire serial interface. Low-current design permits operation with max. standby and active currents of only 5 μA and 1 mA, respectively. The device has a page write capability for up to 16 bytes of data and has fast write cycle times of only 1 ms for both byte and page writes. Functional address lines allow the connection of up to eight 24C02C devices on the same bus for up to 16K bits of contiguous EEPROM memory. The device is available in the standard 8-pin PDIP, 8-pin SOIC (3.90 mm), 8-pin 2x3 DFN and TDFN, 8-pin MSOP and TSSOP packages.

前言 在实际的应用中,我们需要一些存储介质帮助我们来存储一些东西,如保存一些参数和配置数据等。比较常用的有AT24Cxx系列。AT24C02芯片是以IIC接口的EEPROM器件。所谓EEPROM即电
AT24C01/02/04/08/16...是一个1K/2K/4K/8K/16K位电可擦除PROM,内部含有128/256/512/1024/2048个8位字节,AT24C01有一个8字节页写缓冲器,AT24C02/04/08/16有一个16字节页写缓冲器。
现在我们已经实现了AT24C02的单字节读写,但是对于对于2K内存来说,如果对全部数据的读取或者写入都只用单字节读写来完成,这样就会很不方便。
上次已经完成了IIC读写AT24C02的协议层,现在开始编写读写AT24C02的驱动函数。先从单字节的读写开始。
要用IIC读写AT24C02,首先要了解IIC是什么。
使用Platformio平台的libopencm3开发框架来开发STM32G0,以下为EEPROM M24C02的使用方法。
本文是IIC总线的实际应用,将带领读者一步一步阅读AT24C02数据手册,看时序图了解如何使用IIC接口EEPROM存储模块AT24C02,并编写代码使用STM32驱动这个模块。
本文主要介绍了一下目前市场上面24C02几种打线方式的区别,有利于消费者在芯片选型替代、电路设计、软件编程的注意一些细节,另外就是给出了用C语言软件模拟I2C协议和用汇编语言软件模拟I2C协议对24C02进行存取数据的代码
