Frequently Asked Questions
Q1: What do suffix AD / AE stand for on SAK‑TC387TP‑128F300S?
A: AD / AE are distributor‑added silicon stepping codes, not part of Infineon original part‑number. The base factory part‑number is SAK‑TC387TP‑128F300S.
Q2: What is the difference between TP and QP version of TC387?
A: TP (Trusted‑Performance‑cost‑optimized): 8MB Flash / 728KB SRAM；QP (Quad‑Performance‑high‑performance):10MB Flash /1568KB SRAM. They are pin‑to‑pin compatible in PG‑LFBGA‑292 package, but memory capacity differs. Firmware cannot be directly reused without modification.
Q3: Can SAK‑TC387TP‑128F300S directly replace SAK‑TC387QP‑160F300S?
A: Hardware pinout is compatible. But TP has smaller Flash and SRAM. Only use as replacement if your firmware fits inside 8MB Flash /728KB SRAM; otherwise select QP version.
Q4: Difference between SAK prefix and SAL prefix?
A: SAK:‑40℃~+125℃ automotive grade; SAL:‑40℃~+150℃ high‑temperature extended grade. Same package and pinout, choose based on junction‑temperature requirements of your system.
Q5: What functional safety level does SAK‑TC387TP‑128F300S‑AD support?
A: Supports ISO 26262 up to ASIL‑D. Equipped with lock‑step cores, hardware ECC, SMU safety unit and integrated HSM hardware security module.
Q6: What are pin‑compatible alternative cross‑reference models?
A: Pin‑compatible alternatives: SAK‑TC387QP‑160F300S (higher‑memory QP version), SAL‑TC387TP‑128F300S (high‑temp SAL variant). TC377 series is NOT drop‑in compatible (less memory & peripherals).
Q7: How to obtain datasheet, CAD footprint and bulk quotation?
A: Datasheet, LFBGA‑292 footprint drawing, pinout, stock status and volume pricing can be obtained by submitting our quick‑inquiry form.
