FAQ
Does CY8C4247LTQ-L485 support USB device enumeration without external PHY?
Yes. The part integrates a full-speed USB 2.0 PHY with on-die transceivers, allowing direct connection to USB connectors using only standard 27 Ω series resistors and proper PCB layout. Battery Charger Detect (BCD) is implemented in hardware and requires no firmware intervention for basic charger identification.
What is the maximum operating temperature for continuous Deep Sleep with active CSD?
The device maintains guaranteed CSD functionality-including SmartSense™ auto-tuning and >5:1 SNR-in Deep Sleep mode across the full industrial temperature range (–40 °C to +85 °C), as verified in Infineon's electrical specifications section 5.3.5 and thermal characterization data.
Can the opamps operate as unity-gain buffers during Stop Mode?
No. Unity-gain buffer operation requires active biasing and is not supported in Stop Mode (20 nA). However, all four opamps remain fully functional in Deep Sleep mode at typical currents below 0.5 μA per amplifier, enabling continuous sensor signal conditioning with wakeup capability.
How many CAN message objects are supported per controller?
Each CAN controller supports 32 message objects stored in dedicated RAM, configurable as transmit or receive buffers with individual ID masking and filtering. Message RAM is partitioned independently between CAN0 and CAN1, enabling concurrent handling of up to 64 distinct CAN frames without CPU intervention.
