Frequently Asked Questions
Q1: What do LF and V1.3 suffix stand for?
A: “LF” means lead‑free RoHS‑compliant package. “V1.3” is silicon revision for improved USB timing, electrical specs remain unchanged.
Q2: Is SAF‑C165UTAH‑LF V1.3 ROM‑Less?
A: Yes. External Flash/ROM is required for program storage; internal RAM is 2KB‑3KB for runtime data.
Q3: Can this IC be used for new‑product designs?
A: Not recommended. It is NRND / discontinued, only for legacy equipment repair and spare‑part replacement.
Q4: Are there pin‑to‑pin compatible replacements?
A: No direct drop‑in alternative. Most C166 successors differ in package or peripherals, system redesign is needed.
Q5: What tools support the C166 series?
A: Keil C166, Tasking C166 compiler and Infineon official debug hardware.
Q6: What is its power‑supply requirement?
A: 3.0V‑3.6V (typical 3.3V). 5V supply is not supported and will damage the chip.
Q7: How can I get the original datasheet?
A: Submit request via Quick Inquiry form, we will send datasheet resources within 24 working hours.
