M27C4002集成电路（IC）的存储器规格书PDF中文资料

M27C4002属于集成电路（IC）的存储器。由意法半导体集团制造生产的M27C4002存储器存储器是集成电路上用作数据存储设备的半导体器件。这些器件分为非易失性或易失性两种，格式包括 CBRAM、DRAM、EEPROM、EERAM、EPROM、闪存、FRAM、NVSRAM、PCM (PRAM)、PSRAM、RAM 和 SRAM。这些器件的存储容量为 64 b 至 6 Tb 不等，接口有 I2C、MMC、并行、eMMC、串行、单线、SPI、UFS、Xccela 总线和 1-线。

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.
