ADSP-2186:  16-bit, 40 MIPS, 5v, 2 serial ports, host port, 40 KB RAM

Product Description

The ADSP-2186 is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications. ADI recently disclosed plans for a new ADSP-219x series. With speeds beyond 300MIPS, this new series is ADSP-218x code-compatible.

The ADSP-2186 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-2186 integrates 40K bytes of on-chip memory configured as 8K words (24-bit) of program RAM and 8K 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-2186 is available in 100-pin LQFP package.

Features

  • 25 ns Instruction Cycle Time 40 MIPS Sustained Performance
  • Single-Cycle Instruction Execution
  • ADSP-2100 Family Code Compatible, with Instruction Set Extensions
  • 40K Bytes of On-Chip RAM, Configured as 8K Words On-Chip Program Memory RAM and 8K Words On-Chip Data Memory RAM
