Microchip’s 25AA/25LC EEPROMs are data storage chips with a simple 3-wire interface. The 25AA/LC is an SPI version of the common 24AA/LC I2C EEPROM. It comes in capacities of 128bytes to 128kilobytes.

The 24AA52 is a 2 kbit I2C™ serial electrically erasable programmable ROM (EEPROM) with software write protect for lower half array and external pin used to write-protect the entire array. The device ...

This application note explains how to control Renesas Electronics R1EX25xxx/HN58X25xx series SPI Serial EEPROMs and how to use the sample code for the products. This sample code lies in a higher-level ...

While I was searching for a way to dump an entire I2C EEPROM and save it as a binary file on the PC, I stumbled on the original work, mentioned above, for SPI EEPROMs. As it uses a small program ...

EEPROM chips are often used to store configuration information and connected over I2C. But there are also SPI EEPROM, and STMicro has just announced one of the largest ones with M95M04-DR 4-Mbit ...

Microchip Technology has released 24CS512, the first commercially available I 2 C Serial EEPROM with support for 3.4 Mbit/s data rates. This high-speed I 2 C EEPROM is 3 to 4 times faster than the ...

Most micro-controllers comes with both SRAM volatile memory, and flash or EEPROM for non-volatile (persistent) memory, but Texas Instruments – and other companies – have been selling MCUs with FRAM ...

Every time one of us flashes an Arduino’s internal memory, a nagging thought in the backs of our minds reminds us that, although everything in life is impermanent, nonvolatile re-writable memory is ...
