Frequently Asked Questions
Q1: What safety standard level does SAK‑TC397XX‑256F300S BC satisfy?
A1: Supports ISO 26262 ASIL‑D / SIL‑3, for safety‑critical automotive applications.
Q2: What does suffix BC / BD mean for SAK‑TC397XX‑256F300S?
A2: BC and BD are only reel‑tape packing codes, no temperature difference. BC is pin‑to‑pin and electrically compatible with BD version.
Q3: What is the upgrade of TC3xx family compared to TC2xx AURIX?
A3: TC3xx features higher 300MHz clock, up to 6 TriCore cores, larger memory, plus PCIe, Gigabit Ethernet, EVITA‑Full HSM.
Q4: Can SAK‑TC397XX‑256F300S BC directly drop‑in replace TC387 or TC377?
A4: Not direct drop‑in. Flash/RAM and peripherals differ, hardware modification & firmware migration required.
Q5: What package does SAK‑TC397XX‑256F300S BC adopt?
A5: PG‑LFBGA‑292, 17×17 mm, 292‑ball BGA SMD surface‑mount package.
Q6: Does this MCU integrate hardware security module?
A6: Yes, EVITA‑Full HSM on‑chip, supports secure boot, crypto acceleration and anti‑tamper for OTA update.
Q7: How can I get datasheet, pinout map and volume quotation?
A7: Datasheets, pin‑maps, stock and bulk price are available via Quick Inquiry form.
Q8: Is SAK‑TC397XX‑256F300S BC still active for new designs? What is XX suffix mean?
A8: This part is obsolete. “XX” is placeholder suffix. New‑design choose: TC397‑XP(standard), XA(high‑temp up to +150℃), XE(enhanced).
Q9: Is TC397‑XP pin‑compatible with original SAK‑TC397XX‑256F300S BC?
A9: Yes, pin‑to‑pin compatible under same PG‑LFBGA‑292 package. Minor firmware adjustment recommended.
