1 Description
The M95M01 devices are Electrically Erasable PROgrammable Memories (EEPROMs)
organized as 131072 x 8 bits, accessed through the SPI bus.
The M95M01-R devices can operate with a supply range from 1.8 V up to 5.5 V, the
M95M01-DF devices can operate with a supply range from 1.7 V up to 5.5 V. These devices
are guaranteed over the -40 °C/+85 °C temperature range.
The M95M01-DF offers an additional page, named the Identification Page (256 bytes). The
Identification Page can be used to store sensitive application parameters which can be
(later) permanently locked in Read-only mode.
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.
