Features
Description
The AT75C221, Atmel’s latest device in the family of smart internet appliance proces-
sors (SIAP
appliance applications such as the Ethernet IP phone. The AT75C221 is built around
an ARM7TDMI microcontroller core running at 40 MHz with an OakDSPCore copro-
cessor running at 60 MHz and a dual Ethernet 10/100 Mbits/sec MAC interface.
In a typical standalone IP phone, the DSP handles the voice processing functions
(voice compression, acoustic echo cancellation, etc.) while the dual-port Ethernet
10/100 Mbits/sec MAC interface establishes the connection to the Ethernet physical
layer (PHY) that links the network and the PC. In such an application, the power of the
ARM7TDMI allows it to run a VoIP protocol stack as well as all the system control
tasks.
Atmel provides the AT75C221 with several software modules, including:
ARM7TDMI
16-bit Fixed-point OakDSPCore
Ethernet Bridge
1 K-Byte Boot ROM, Embedding a Boot Program
External Bus Interface
Multi-level Priority, Individually Maskable, Vectored Interrupt Controller
