M95128 128千比特串行SPI总线的EEPROM高速时钟
The M95128, M95128-W and M95128-R are electrically erasable programmable memory (EEPROM) devices accessed by a high speed SPI-compatible bus. The memory array is organized as 16384 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).
In order to meet environmental requirements, ST offers these devices in ECOPACK? packages. ECOPACK? packages are Lead-free and RoHS compliant. ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com.
