16-bit, 52 MIPS, 3.3 v, 2 serial ports, host port, 80 KB RAM

The ADSP-2183 is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications.

The ADSP-2183 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-2183 integrates 80K bytes of on-chip memory configured as 16K words (24-bit) of program RAM, and 16K 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-2183 is available in a 128-lead LQFP package.

In addition, the ADSP-2183 supports new instructions, which include bit manipulations-bit set, bit clear, bit toggle, bit test- new ALU constants, new multiplication instruction (x squared), biased rounding, result free ALU operations, I/O memory transfers and global interrupt masking, for increased flexibility.

Fabricated in a high speed, double metal, low power, CMOS process, the ADSP-2183 operates with a 19 ns instruction cycle time. Every instruction can execute in a single processor cycle.

The ADSP-2183's flexible architecture and comprehensive instruction set allow the processor to perform multiple operations in parallel. In one processor cycle the ADSP-2183 can:

* generate the next program address

* fetch the next instruction

* perform one or two data moves

* update one or two data address pointers

* perform a computational operation

* 19 ns Instruction Cycle Time from 26.32 MHz Crystal @ 3.3 Volts

* 52 MIPS Sustained Performance

* 80K Bytes of On-Chip RAM, Configured as 16K Words On-Chip Program Memory RAM and 16K Words On-Chip Data Memory RAM

* Dual Purpose Program Memory for Both Instruction and Data Storage
