General Description

The EC24C04T is a 4-Kbit I 2 C-compatible Serial EEPROM 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, over an operating temperature range of -40°C to +105°C.
The device incorporates a Write Protection pin used for hardware Write Protection on the whole memory array.
The device also offers a Software Write Protection feature for users to write protect the whole memory array.
The memory array is organized as 32 pages of 16 bytes each, totaling 512*8 bits.
The device offers an additional 16-byte Identification Page for users to store sensitive application parameters.
This page can be permanently locked in Read-only mode after the data is written into the Identification Page.
The device also offers a separate memory block (in Read-only mode) containing a factory programmed 128-bit Unique ID and can be accessed to by sending a specific Read command.
The EC24C04T is delivered in Lead-free green package: SOP-8.
