M24256-BR屬于集成電路（IC）的存儲(chǔ)器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的M24256-BR存儲(chǔ)器存儲(chǔ)器是集成電路上用作數(shù)據(jù)存儲(chǔ)設(shè)備的半導(dǎo)體器件。這些器件分為非易失性或易失性兩種，格式包括 CBRAM、DRAM、EEPROM、EERAM、EPROM、閃存、FRAM、NVSRAM、PCM (PRAM)、PSRAM、RAM 和 SRAM。這些器件的存儲(chǔ)容量為 64 b 至 6 Tb 不等，接口有 I2C、MMC、并行、eMMC、串行、單線、SPI、UFS、Xccela 總線和 1-線。

描述 Description

The M24512-W, M24512-R, M24512-HR, M24256-BF, M24256-BW, M24256-BR and M24256-BHR devices are I2C-compatible electrically erasable programmable memories (EEPROM). They are organized as 64 Kb × 8 bits and 32 Kb × 8 bits, respectively.

I2C uses a two-wire serial interface, comprising a bidirectional data line and a clock line. The devices carry a built-in 4-bit Device Type Identifier code (1010) in accordance with the I2C bus definition. 2
