N21C21ASNDT3G Description

Short technical summary and product information.

The ON Semiconductor N21C21ASNDT3G is a 1 Kbit EPROM (Erasable Programmable Read-Only Memory) integrated circuit. This non-volatile memory utilizes a 1-Wire interface for communication and operates within a voltage range of 2.65V to 5.5V. The device has a write cycle time of 5µs and is organized as 128 x 8 bits.

 

Designed for surface mounting, the N21C21ASNDT3G comes in a compact SOT-23-3 package (also referred to as TO-236-3 or SC-59). It operates across a temperature range of -40°C to 85°C. This OTP (One-Time Programmable) EPROM is suitable for applications requiring small, non-volatile data storage where a simple interface is beneficial.
