M95256 256千比特串行SPI总线的EEPROM与高速时钟
The M95256, M95256-W and M95256-R are electrically erasable programmable memory (EEPROM) devices. They are accessed by a high speed SPI-compatible bus. Their memory array is organized as 32768 x 8 bits.
The device is accessed by a simple serial interface that is SPI-compatible. The bus signals are C, D and Q, as shown in Table 1 and Figure 1. The device is selected when Chip Select (S) is taken low. Communications with the device can be interrupted using Hold (HOLD).
