DS24L65P+

Specialized ICS Overview

The DS24L65P+ is a DeepCover Secure Authenticator featuring an integrated SHA-256 coprocessor and a 1-Wire master controller. It facilitates protocol conversion between an I2C host and 1-Wire SHA-256 slave devices, handling time-critical waveform generation to relieve the system processor. The device includes two 32-byte user EEPROM pages with programmable protection options. It operates on a 1.8V supply (1.71V to 1.89V) within a temperature range of -40°C to +85°C. Key electrical characteristics include a typical operating current of 750µA and sleep mode current of 0.5µA to 1.0µA. The component is housed in a 6-pin TSOC package.
