93C66BT-I/OT Description

Short technical summary and product information.

The Microchip Technology 93C66BT-I/OT is a 4Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) device. It utilizes a 3-wire serial interface, commonly known as Microwire, for data communication.

 

This EEPROM operates within a supply voltage range of 4.5V to 5.5V and is designed for industrial temperature applications, functioning reliably between -40°C and 85°C. The memory organization is 256 words by 16 bits, providing a total storage capacity of 4Kbit. It supports a clock frequency of up to 2 MHz.

 

The device is manufactured using advanced CMOS technology, making it suitable for low-power applications. It features self-timed erase/write cycles and power-on/off data protection circuitry. The 93C66BT-I/OT is available in a SOT-23-6 surface mount package, ideal for space-constrained designs.

 

Key features include its non-volatile memory type, EEPROM technology, and a write cycle time of 2ms. The device is designed for applications requiring reliable data storage in a compact form factor.
