General Description

The EC24C128T is a 128-Kbit I 2 C-compatible Serial EEPROM (Electrically Erasable Programmable Memory) device.
The device is designed to operate in a supply voltage range of 1.7V to 5.5V, with a maximum of 1MHz transfer rate. The operating temperature range is from -40°C to +105°C.
The device incorporates a Write Protection pin used for hardware Write Protection on the whole memory array.
The Serial EEPROM memory is organized as 256 pages of 64 bytes each, totaling 16384*8 bits.
The EC24C128T offers an additional 64-byte Identification Page for users to store sensitive application parameters.
This page can be permanently locked in Read-only mode after the application data is written into the Identification Page.
The EC24C128T also offers a separate memory block containing a factory programmed 128-bit Unique ID.
This block is in Read-only mode and can be accessed to by sending a specific Read command The EC24C128T is delivered in Lead-free green packages: TSSOP-8, SOP-8, SOT23-5
