M24512E-F数据手册ST中文资料规格书

描述 Description

The M24512E-F is a 512-Kbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 64 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 M24512E-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 eight 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 M24512E-F offers an additional page, named the identification page (128-byte). The identification page can be used to store sensitive application parameters which can be (later) permanently locked in read-only mode.

The M24512E-F is available in the standard 8-pin TSSOP8, SO8N, and UFDFPN8 with the WC pin.

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