| I2C EEPROMs compatible with Atmel's AT24 family |
| |
| There are multiple vendors manufacturing I2C EEPROMs compatible with the programming model of the |
| Atmel AT24. |
| |
| Examples of compatible EEPROM families: |
| - Microchip AT24xxx |
| - ST M24xxx |
| |
| Each of these can be represented by a set of common parameters (EEPROM size, page size, address |
| width, and timeout) available from the datasheet of the specific EEPROM. The compatible string for |
| these can list the specific EEPROM vendor and model along with the vendor EEPROM family as long as |
| the least-specific compatible entry is "atmel,at24". |
| |
| Example devicetree node describing a ST M24M01 EEPROM on the i2c0 bus: |
| |
| &i2c0 { |
| status = "okay"; |
| clock-frequency = <I2C_BITRATE_FAST>; |
| |
| eeprom@56 { |
| compatible = "st,m24m01", "st,m24xxx", "atmel,at24"; |
| reg = <0x56>; |
| size = <DT_SIZE_K(128)>; |
| pagesize = <256>; |
| address-width = <16>; |
| timeout = <5>; |
| }; |
| }; |
| |
| compatible: "atmel,at24" |
