HG24C64CM/TR

The HG24C64C is a 64-Kbit I²C-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℃ to +105℃. 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 32 bytes each, totaling 8192 * 8 bits. The HG24C64C offers an additional 32-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 HG24C64C 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 HG24C64C is delivered in lead-free green packages: SOP, MSOP, TSSOP, DFN and SOT.
