Description

The M95080 devices are Electrically Erasable PROgrammable Memories (EEPROMs)

organized as 1024 x 8 bits, accessed through the SPI bus.

The M95080 devices can operate with a supply range from 1.8 V up to 5.5 V, and are

guaranteed over the -40 °C/+85 °C temperature range.

Figure 1.

Logic diagram

The SPI bus signals are C, D and Q, as shown in Figure 1 and Table 1. The device is

selected when Chip Select (S) is driven low. Communications with the device can be

interrupted when the HOLD is driven low.
