M95M02-DR中文资料2 Mbit串行SPI总线EEPROM数据手册ST规格书

描述 Description

The M95M02 devices are electrically erasable programmable memory (EEPROM) organized as 262144 x 8 bits, accessed through the SPI bus.

Over an ambient temperature range of -40 °C / +85 °C the M95M02-DR can operate with a supply voltage from 1.8 to 5.5 V. Over an ambient temperature range of -20 °C / +85 °C the M95M02-DF can operate with a supply voltage from 1.7 to 5.5 V.

The M95M02 devices offer an additional page, named the Identification page (256 bytes). The Identification page can be used to store sensitive application parameters that can be (later) permanently locked in read-only mode.

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.
