The AT24MAC402-STUM-T from Microchip Technology is a 2Kbit serial EEPROM organized as 256 words of 8 bits each. It utilizes an I2C-compatible, 2-wire serial interface for data transfer.
This device supports a clock frequency of up to 1MHz (at 2.5V/5.0V) and operates with a low voltage range of 1.7V to 5.5V. Key features include a write cycle time of 5ms maximum and an access time of 550 ns. The EEPROM offers hardware write protection for the entire array and permanent/reversible software write protection for the first half of the array.
Enhanced features include a factory-programmed, permanently locked, read-only EUI-48 compatible address and a unique factory-programmed 128-bit serial number, both stored in a separate memory area. The AT24MAC402-STUM-T is designed for high reliability with an endurance of 1,000,000 write cycles and data retention of 100 years.
It is available in a compact SOT-23-5 package, suitable for surface mounting. The operating temperature range is -40°C to 85°C (TA). This component is also noted for its green package options, being PB/Halide-free and RoHS compliant.
