ADSP-21mod970 General Description

The ADSP-21mod970 is a Multiport Internet Gateway Processor optimized for implementation of a complete V.34/56K modem. All data pump and controller functions can be implemented on a single device, offering the lowest power consumption and highest possible modem port density.

The ADSP-21mod970 combines the ADSP-2100 family base architecture (three computational units, data address generators and a program sequencer) with two serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, Flag I/O,
extensive interrupt capabilities and on-chip program and data memory.

The ADSP-21mod970 integrates 960 bytes of on-chip memory, configured as 192K words (24-bit) of program RAM, and 192K words (16-bit) of data RAM. Power-down circuitry is also provided to meet the low power needs of battery operated portable equipment. The ADSP-21mod970 is available in a 31 sq-mm., 304-lead PBGA package.
