6 / 41 page  Description M24256-BW M24256-BR M24256-BF M24256-DR M24256-DF 6/41 Doc ID 6757 Rev 28 1 Description The M24256 is a 256-Kbit I2C-compatible EEPROM (Electrically Erasable PROgrammable Memory) organized as 32 K × 8 bits. The M24256-BW 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 from 1.7 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-Dx 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. Figure 1. Logic diagram Table 1.
