M35080MN Datasheet 8-Kbit Serial SPI Bus EEPROM

Manufacturer: STMicroelectronics

General Description

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

The device 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.

Key Features

  • of the memory device are summarized in Table 3. The hardware write protection, controlled by the W pin, restricts write access to the Status Register M35080 VSS S W Q 1 2 3 4 8 7 6 5 AI02144B VCC D C NC Note: 1. NC = Not Connected. The memory is organized in pages of 32 bytes. However, the first page is not treated in the same way as the others. Instead, it is considered to consist of sixteen 16-bit incremental registers. Each register can be modified using the conventional write instruction.
