Frequently Asked Questions
Q1: What CPU architecture is used in the SAK‑C167CS‑L40M CA+?
A: It adopts Infineon 16‑bit C166 core with mixed CISC/RISC instruction set, maximum operating frequency up to 40 MHz.
Q2: Does SAK‑C167CS‑L40M CA+ have on‑chip Flash or ROM?
A: No. This is a ROMless variant. It requires external Flash/EPROM memory via EBI/EMI external bus interface to run program code.
Q3: Does this MCU come with integrated CAN controller?
A: Yes. Dual‑channel Full‑CAN 2.0B controllers with total 30 message objects for automotive network communication.
Q4: How can I get datasheets, pinout, stock or volume pricing?
A: Please submit your request through our Quick Inquiry form. We will provide documentation, stock status and quotation within 24 hours.
Q5: What does suffix “CA+” mean in SAK‑C167CS‑L40M CA+?
A: “CA+” stands for automotive‑grade, qualified for -40°C ~ +125°C. Other suffixes like CA, AA represent different temperature and quality grades.
Q6: What is the difference between PG‑MQFP‑144‑1 and P‑MQFP‑144?
A: PG‑MQFP‑144‑1 is Infineon official package code; P‑MQFP‑144 is industry shorthand. Both are 144‑pin MQFP, 28×28×3.85 mm, pin‑to‑pin fully compatible.
Q7: What are pin‑compatible drop‑in alternatives for SAK‑C167CS‑L40M CA+?
A: Direct pin‑compatible variants: SAK‑C167CS‑L40M CA, SAK‑C167CS‑L25M CA+.
Note: L40M = 40 MHz, L25M = 25 MHz.
For new‑project designs, use modern Infineon AURIX TC27x / TC37x series as functional replacement.
Q8: Is SAK‑C167CS‑L40M CA+ still in active production?
A: No, this part is End‑of‑Life (Discontinued). We supply original surplus stock for legacy system maintenance. New designs should adopt AURIX MCU family.
Q9: What are competing MCU models for similar automotive applications?
A: Competitors: Infineon C167CR series, Microchip dsPIC33CH, NXP S12X series. This MCU excels for legacy automotive ECUs with dual‑CAN, wide‑temperature rating and large external memory bus.
