General Description

The EC24C32T is a 32-Kbit I2C-compatible Serial EEPROM (Electrically Erasable Programmable Memory) device.
The device is designed to operate in a supply voltage range of 1.6V 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 device also offers a Software Write Protection feature for users to write protect the whole memory array.
The Serial EEPROM memory is organized as 128 pages of 32 bytes each, totaling 4096*8 bits.
The device offers an additional 32-byte Identification Page for users to store sensitive application parameters.
This page can be ermanently locked in Read-only mode after the application data is written into the Identification Page.
The C24C32T 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 EC24C32T is delivered in Lead-free green packages: TSSOP-8, SOP-8
