GENERAL DESCRIPTION The ADSP-2186L is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications. The ADSP-2186L combines the ADSP-2100 family base archi- tecture (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-2186L 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 pro- vided to meet the low power needs of battery operated portable equipment. The ADSP-2186L is available in a 100-lead LQFP and 144-ball mini-BGA packages. In addition, the ADSP-2186L 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 trans- fers and global interrupt masking for increased flexibility.
