Frequently Asked Questions
Q1: What is the processing speed of ADSP‑2185MKSTZ‑300?
A1: 30 MHz clock, peak 30 MIPS, 33.3 ns instruction cycle. Note:75MIPS belongs to ADSP‑2188M, do not confuse the two models.
Q2: How much on‑chip memory does this DSP have?
A2: Total 80 KB SRAM:16K×24‑bit Program RAM,16K×16‑bit Data RAM.
Q3: What is the meaning for each suffix of ADSP‑2185MKSTZ‑300?
A3: M‑memory variant; KS‑LQFP‑100 package; T‑0~70℃ commercial grade; Z‑lead‑free; ‑300‑30MHz clock; suffix‑B stands for industrial temperature version.
Q4: Can other ADSP‑218x models be pin‑to‑pin compatible?
A4: ADSP‑2184 / ADSP‑2186 share same LQFP‑100 footprint. Please verify RAM size & timing before drop‑in replacement.
Q5: Can ADSP‑2185MKSTZ‑300 be used for new‑product development?
A5: This part is NRND, stocks are only for legacy‑equipment maintenance. Choose modern DSP/MCU for new‑design projects.
Q6: What is difference between T(commercial) and B(industrial) suffix?
A6: Same package & pinout. T:0‑70℃ commercial grade; B:‑40~+85℃ industrial wide‑temperature grade.
Q7: Does I/O support 5V system signal?
A7: I/O powered by 3.3V, pins tolerate 5V input signal, cannot output 5V level.
Q8: How to get datasheet, CAD files or bulk‑order price?
A8: Submit quick‑inquiry form for datasheet, pinout, stock status and quotation.
