M95640-DF中文资料64 Kbit SPI总线EEPROM，带高速时钟数据手册ST规格书

描述 Description

The M95640 devices are electrically erasable programmable memories (EEPROMs) organized as 8192 x 8 bits, accessed through the SPI bus.

The M95640-W can operate with a supply voltage from 2.5 V to 5.5 V, the M95640-R can operate with a supply voltage from 1.8 V to 5.5 V and the M95640-DF can operate with a supply voltage from 1.7 V to 5.5 V, over an ambient temperature range of -40 °C / +85 °C.

The M95640-D offers an additional page, named the identification page (32 bytes). The identification page can be used to store sensitive application parameters which can be (later) permanently locked in read-only mode.

The SPI bus signals are C, D and Q. The device is selected when chip select (S) is driven low. Communications with the device can be interrupted when the HOLD is driven low.
