M27C4002集成電路（IC）的存儲(chǔ)器規(guī)格書(shū)PDF中文資料

M27C4002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M27C4002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。

Summary description

The M27C4002 is a 4 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems requiring large programs and is organized as 262,144 words of 16 bits.

The FDIP40W (window ceramic frit-seal package) has transparent lids which allow the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written to the device by following the programming procedure.

For applications where the content is programmed only one time and erasure is not required, the M27C4002 is offered in PDIP40, PLCC44 and TSOP40 (10 x 20 mm) packages.

In order to meet environmental requirements, ST offers the M27C4002 in ECOPACK? packages.
