AT75C310 Datasheet Smart Internet Appliance Processor (siap)

Manufacturer: Atmel (now Microchip Technology)

General Description

The Atmel AT75C310 Smart Internet Appliance Processor (SIAP) is a high-performance processor specially designed for Internet appliance applications, such as Internet telephony (Voice over Internet Protocol – VoIP).

The AT75C310 is built around an ARM7TDMI microcontroller core running at 20 MIPS with two DSP co-processors running at 40 MIPS each – all three processors delivering unmatched performance for low power consumption.

In a typical standalone VoIP phone, one DSP handles the voice-processing functions (voice pression, acoustic echo cancellation, etc.), while the other one deals with the telephony functions (dialing, line echo cancellation, callerID detection, high-speed modem, etc.).

Key Features
