What is a 24C16 memory IC?
24C16 is a 16K serial electrically erasable EEPROM memory based on I2C bus protocol. It was launched by Microchip and uses low-power CMOS technology, with a maximum current of 5mA when writing under a 5.5V power supply. 24C16 has page write capability, 1 million erase and write times, and data retention period of more than 200 years.
Microchip was acquired by STMicroelectronics, so it is a chip produced by STMicroelectronics. It has the characteristics of being rewritable 1 million times and retaining data for 40 years without loss. The operating voltage range is 4.5V – 5.5V.
During system design, the number of different chips is expanded according to the needs of storage capacity. On the same I2C bus, we can expand up to eight 24C16 chips, with a maximum storage capacity of 1Mbit.
WP is the write protection pin. If WP is connected to high level, the entire memory unit is write-protected, and the data can only be read, not written. If WP is connected to low level or left floating, the memory unit is not write-protected, and the data cannot be written. Can be both read and written.
