The AT75C221 is built around an ARM7TDMI microcontroller core running at 40 MHz with an OakDSPCore coprocessor 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: • • A set of drivers for a Linux® kernel capable of driving the embedded peripherals. A comprehensive set of tunable DSP algorithms for voice processing, tailored to be run by the DSP subsystem. 6033CS–INTAP–05/04 Pinout The AT75C221 ships in two alternative packages: • • 208-lead PQFP 256-ball BGA The product features of the 256-ball BGA package are increased compared to the 208lead PQFP package. The features available only with the BGA package are: • • • The 32-bit wide data bus (In PQFP, only a 16-bit wide data bus is supported.) The Parallel I/O lines PA13 to PA18 and PA20 to PA31 The Parallel I/O lines PB10 to PB16 2 AT75C221 Summary 6033CS–INTAP–05/04 AT75C221 Summary 208-lead PQFP Package Pinout Table 1.
