数据手册.pdf256 Kbit的串行SPI总线的EEPROM与高速时钟 256 Kbit Serial SPI bus EEPROM with high speed clock
Description
The M95256, M95256-W, M95256-R and M95256-DR are electrically erasable programmable memory EEPROM devices. They are accessed by a high speed SPI compatible bus. Their memory array is organized as 32768 × 8 bits. The M95256-DR also offers an additional page, named the Identification Page 64 bytes which can be written and later permanently locked in Read-only mode. This Identification Page offers flexibility in the application board production line, as the Identification Page can be used to store unique identification parameters and/or parameters specific to the production line.
