Note: 1. Except for the rating "Operating Temperature Range", stresses above those listed in the Table "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Refer also to the ST SURE Program and other relevant quality documents.

Description

The M35080 device consists of 1024x8 bits of low power EEPROM, fabricated with STMicroelectronics' proprietary High Endurance Double Polysilicon CMOS technology.

The M35080 is accessed by a simple SPI-compatible serial interface. The bus signals consist of a serial clock input (C), a serial data input (D) and a serial data output (Q), as shown in Table 1.

The M35080 is selected when the chip select input (S) is held low. Data is clocked in during the low to high transition of the clock, C. Data is clocked out during the high to low transition of the clock.
