Description

The M24256 is a 256-Kbit I2 C-compatible EEPROM (Electrically Erasable PROgrammable  Memory) organized as 32 K × 8 bits. The 42568WP can operate with a supply voltage from 2.5 V to 5.5 V, the M24256-BR and M24256-DR can operate with a supply voltage from 1.8 V to 5.5 V, and the M24256-BF and M24256-DF can operate with a supply voltage from1.7 V to 5.5 V. All these devices operate with a clock frequency of 1 MHz (or less), over an ambient temperature range of –40 °C / +85 °C.
The M24256-D offers an additional page, named the Identification Page (64 bytes). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode.

AT24C08 eeprom atmel

Description

The AT24C08 provides 8192 bits of serial electrically erasable and programmable read only memory EEPROM) organized as 1024 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential.

AT24C08, 8K SERIAL EEPROM: The 8K is internally organized with 4 blocks of 256 pages of 4 bytes each. Random word addressing requires a 10-bit data word address.

The AT24C08 only uses the A2 input for hardwire addressing and a total of two 8K devices may be addressed on a single bus system. The A0 and A1 pins are no connects.
