Frequently Asked Questions
Q1: How many CPU cores are in SAK‑TC399XP‑256F300S BD?
A: 10‑core architecture: 6 main 32‑bit TriCore™ cores plus 4 lock‑step checker cores, up to 300 MHz, delivering ~4000 DMIPS performance.
Q2: What is the memory configuration?
A: 16 MB ECC‑protected Flash, 6.9 MB ECC‑protected SRAM, and 1 MB on‑chip EEPROM.
Q3: What package is used for this MCU?
A: PG‑LFBGA‑516 (516‑ball surface‑mount package). Note: LFBGA‑292 is for TC397 series, not TC399XP.
Q4: What is the operating temperature range?
A: SAK variant:‑40℃~+125℃; SAL variant:‑40℃~+150℃. They are not pin‑compatible for temperature‑critical designs.
Q5: What is the difference between TC399XP and TC399XX?
A: TC399XP is the full‑feature 10‑core version. TC399XX is a 6‑core basic variant with fewer peripherals and lower computing capacity.
Q6: Are there pin‑compatible replacement parts?
A: Within AURIX TC39x family, SAK‑TC399XP‑256F300S‑BD shares pinout with other TC399XP variants (different feature sets). TC397 series uses LFBGA‑292, not pin‑compatible. No direct pin‑to‑pin drop‑in replacement from other vendors.
Q7: Does this MCU support ISO 26262 ASIL‑D functional safety?
A: Yes. It is ISO 26262 ASIL‑D / SIL‑3 qualified, with lock‑step cores, memory ECC and hardware self‑diagnosis mechanisms.
Q8: What is the power supply requirement?
A: Wide‑range single‑power supply: 2.97 V‑5.5 V, supports both 3.3 V and 5 V system power designs.
Q9: Can I use TC397XP to replace TC399XP in existing hardware?
A: No. TC397XP uses LFBGA‑292 package, while TC399XP uses PG‑LFBGA‑516. Ball count and pin assignment differ, direct hardware replacement is not allowed.
Q10: How to get datasheets, pinout details or volume quotes?
A: Request datasheets, CAD footprints, stock check and bulk pricing via our Quick Inquiry form. We will reply within 24 hours.
