Description
The M24256 is a 256-Kbit I
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.
