资 源 简 介
The DS2465 is a SHA-256 coprocessor with built-in1-Wire® master that provides the SHA-256 and memoryfuncTIonality required by a host system to communicatewith and operate a 1-Wire SHA-256 slave. In addiTIon, itperforms protocol conversion between the I2C masterand any attached 1-Wire SHA-256 slaves. For 1-Wire linedriving, internal user-adjustable TImers relieve the systemhost processor from generaTIng time-critical 1-Wire waveforms,supporting both standard and overdrive 1-Wirecommunication speeds. The 1-Wire line can be powereddown under software control. Strong pullup features support1-Wire power delivery to 1-Wire devices such asEEPROMs. When not in use, the DS2465 can be put insleep mode where power consumption is minimal.
