The DS28E10R+T is a specialized memory integrated circuit from Analog Devices / Maxim Integrated, designed for secure authentication applications. It features a 224-bit One-Time Programmable (OTP) EPROM memory, which is automatically write-protected once programmed.
This device incorporates a dedicated hardware-accelerated SHA-1 engine for generating secure hash algorithm message authentication codes. It communicates using the standard 1-Wire bus protocol, allowing for efficient data transfer at speeds up to 15.4kbps in standard mode and up to 125kbps in overdrive mode. Each DS28E10R+T is factory-programmed with a unique 64-bit ROM identification number.
The operating voltage range for this component is 2.8V to 3.6V, with an operating temperature range of -40°C to +85°C. It is supplied in a compact SOT-23-3 surface-mount package, making it suitable for space-constrained designs. The device also offers ±6kV Human Body Model (HBM) ESD protection on its 1-Wire and VCC pins.
Applications for the DS28E10R+T include license management, system intellectual property protection, and sensor/accessory authentication and calibration, where secure identification and data integrity are critical.
