Frequently Asked Questions
Q1: What does each suffix in ADSP‑21161NKCAZ100 mean?
A: NK = Commercial 0~+85°C, plastic BGA; CA = 225‑ball CSPBGA package; Z = RoHS lead‑free; 100 = 100MHz core clock.
Q2: What is the computing performance of ADSP‑21161NKCAZ100?
A: At 100MHz core clock, peak performance reaches 600 MFLOPS / 100 MIPS for floating‑point signal processing.
Q3: Does ADSP‑21161NKCAZ100 support multi‑processor operation?
A: Yes. It supports glue‑less interconnection of up to 6 SHARC DSPs on one shared bus, no extra logic chip required.
Q4: Is ADSP‑21161NKCAZ100 NRND?
A: Yes, NRND‑Not Recommended For New Designs. Suitable for BOM maintenance and spare‑part replenishment of legacy projects, not for brand‑new developments.
Q5: Are there pin‑compatible or alternative SHARC DSP parts?
A: ADSP‑21160 series is hardware‑compatible reference. For new designs, ADSP‑2136x series is the recommended upgrade. True pin‑to‑pin drop‑in substitutes are limited; hardware re‑validation is required for any replacement.
Q6: How many SPORT serial ports does this DSP have?
A: Total 4 SPORT ports, supporting I2S audio protocol, each port supports 8‑channel time‑division multiplex audio transmission.
Q7: How can I get datasheet, pinout or bulk quotation?
A: Please submit your demand via Quick Inquiry form. Our team will send datasheet, stock check and price quotation within 24 hours.
