ADSP-2188NKSTZ-320

Digital Signal Processor Dsp Overview

The ADSP-2188NKSTZ-320 is a fixed-point digital signal processor from the Analog Devices ADSP-218xN series, fabricated in a 0.18 μm CMOS process. It delivers 80 MIPS sustained performance with a 12.5 ns instruction cycle time at 1.8 V. The device integrates up to 48K words of program RAM and 56K words of data RAM. Key architectural features include a three-bus architecture for dual operand fetches, independent ALU, MAC, and shifter units, and two serial ports. It supports flexible I/O levels (1.8 V, 2.5 V, or 3.3 V) and includes low-power modes such as power-down with 200 CLKIN cycle recovery.

Digital Signal Processor Dsp Feature Summary

• Battery-operated portable equipment utilizing power-down modes.
• Systems requiring glueless interface to off-chip RAM and I/O peripherals.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'KSTZ' against the manufacturer's ordering guide to confirm package type (LQFP or BGA), temperature range, and lead-free status. Ensure the required clock frequency aligns with the 1.8 V operating condition for optimal performance specifications.

Digital Signal Processor Dsp Selection Notes

Select this model when the application requires the maximum memory configuration within the ADSP-218xN family (48K/56K words). Consider the pin-compatibility with other ADSP-218xN members if future design flexibility regarding memory size is needed. Verify that the 1.8 V core voltage meets the system's power budget constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-218xN series, which shares the ADSP-2100 family base architecture. All members are pin-compatible and differ primarily by on-chip SRAM capacity. The series combines computational units with extensive I/O and interrupt capabilities, targeting embedded DSP tasks.

Digital Signal Processor Dsp Replacement Considerations

Other ADSP-218xN members (e.g., ADSP-2187N, ADSP-2189N) are pin-compatible alternatives with different memory sizes. Cross-check the specific suffix codes for thermal and packaging variations before substitution.
