Overview
Description
The AT93C46D-TH-T is a 1K-bit (128 x 8 or 64 x 16) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Microchip Technology. It is organized as either 128 bytes or 64 words and features a 3-wire serial interface, which includes Data In (DI), Data Out (DO), and a Serial Clock (SK). This EEPROM is designed for use in applications where low-power, non-volatile memory is required. It operates with a supply voltage range of 1.8V to 5.5V, making it suitable for battery-powered devices.
The AT93C46D-TH-T offers a maximum clock frequency of 2 MHz and is known for its high endurance, supporting write/erase cycles of up to 1,000,000 operations. It also provides data retention for up to 100 years, ensuring reliability in long-term applications. The device is available in a thin 8-lead TSSOP package, making it ideal for compact designs. Key features include low power consumption, a self-timed write cycle, and built-in write protection to prevent accidental data corruption.
