DS2465P+

Controllers Overview

The DS2465P+ is a DeepCover Secure Authenticator featuring an integrated SHA-256 coprocessor and a built-in 1-Wire master controller. It facilitates protocol conversion between an I2C host system and attached 1-Wire SHA-256 slave devices, handling time-critical waveform generation without host processor intervention. The device includes two 32-byte pages of user EEPROM with programmable protection options. Electrical specifications include a supply voltage range of 2.97V to 3.63V, operating current of 750µA, and sleep mode current of 0.5µA to 1.0µA. It supports standard and overdrive 1-Wire speeds within an operating temperature range of -40°C to +85°C.

Controllers Feature Summary

• Integrates a SHA-256 engine for symmetric-key-based bidirectional secure authentication
• Includes a self-timed 1-Wire master port supporting active pullup and strong pullup features
• Provides two pages of user EEPROM with multiple programmable protection options
• Supports software-controlled power-down of the 1-Wire line and low-power sleep mode

Controllers Applications

• Authentication of consumables
• Secure feature control
