M24M02E-F中文资料2 Mbit Serial I2C bus EEPROM with configurable device address and software write protection registers数据手册ST规格书

描述 Description

The M24M02E-F is a 2-Mbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 256 K x 8 bits. The device can operate with a supply voltage from 1.6 V to 5.5 V with a clock frequency of 1 MHz (or less), over an ambient temperature range of -40 °C / +85 °C.

The M24M02E-F offers three 8-bit registers. The device type identifier (DTI) register permanently locked in read-only mode. The configurable device address (CDA) register authorizing the user, through software, to configure up to two possibilities of chip enable address. The software write protection (SWP) register authorizing the user, through software, to write protect partial or full memory array.

Moreover, the M24M02E-F offers an additional page, named the identification page (256-byte). The identification page can be used to store sensitive application parameters which can be (later) permanently locked in read-only mode.

The M24M02E-F is available in the standard 8-pin TSSOP8, SO8N, UFDFPN8 and in wafer level chip scale packaging (WLCSP) 5-ball with the WC pin.

On demand, the EEPROM can be delivered by STMicroelectronics with a preprogrammed and locked device address.
