93LC46B/P Description

The 93LC46B/P from Microchip Technology is a 1Kbit (64 x 16) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) featuring a Microwire interface. Designed for reliability and ease of integration, this EEPROM operates across a 2.5V to 5.5V supply range, making it suitable for both low-power and standard voltage applications. With a 2 MHz clock frequency and a 6ms write cycle time (word/page), it balances speed and efficiency for embedded systems. The device is housed in an 8-pin DIP (Through Hole) package, ensuring robust mechanical stability for industrial and commercial applications. It is RoHS3 compliant and rated for 0°C to 70°C operating temperatures, meeting stringent environmental and performance standards.
