FAQ
What is the maximum operating frequency and temperature range for SAK-TC264DC-40F200W BC?
The device operates at up to 200 MHz across the full industrial temperature range of –40 °C to +125 °C, validated per Infineon's BC-step qualification including HTOL, TC, and ESD testing. Core voltage scaling and thermal derating are managed internally via the EVR unit, eliminating external frequency throttling requirements.
Does SAK-TC264DC-40F200W BC support JTAG debugging and secure boot?
Yes - it includes IEEE 1149.1-compliant JTAG/DAP interfaces with boundary-scan and debug access port support. Secure boot is implemented via BootROM (BROM) with hardware-verified signature checking of PFlash images using SHA-256 and RSA-2048 keys stored in protected OTP memory.
How is functional safety achieved without external safety monitors?
Safety is achieved through integrated hardware: lockstep core comparison, ECC on all memories, SMU with 32 configurable fault monitors, safe DMA with address/data integrity checks, and self-test routines for CPU, memory, and peripherals - all certified to ISO 26262 ASIL-D at the SoC level.
What packaging and reflow profile should be used for LQFP144 assembly?
The LQFP144 package uses standard JEDEC MS-026AC footprint with 0.5 mm pitch and exposed thermal pad. Reflow must follow IPC-J-STD-020D Level 3 profile: peak temperature 260 °C, time above 217 °C ≤ 60 s, ramp rate ≤ 3 °C/s. Thermal pad requires ≥70% solder coverage and controlled voiding (<25%) per IPC-7092.
