Yes, the R5F511JADLM#UA integrates a USB 2.0 full-speed host/function/OTG module compliant with USB 2.0 specifications. It requires dedicated VCC_USB and VSS_USB pins, and supports 12 Mbps (full-speed) and 1.5 Mbps (low-speed) modes. No external transceiver is needed - only series resistors and ESD protection diodes are required on USB0_DP/USB0_DM.
What low-power modes are available on the R5F511JADLM#UA, and how fast is wake-up from standby?
The R5F511JADLM#UA supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it draws just 0.44 μA and recovers in 4.8 μs - making it suitable for battery-powered applications where rapid response to external triggers (e.g., USB activity or RTC alarm) is essential.
Can the R5F511JADLM#UA perform background data flash writes while running application code?
Yes, the R5F511JADLM#UA supports Background Operation (BGO) for its 8 KB data flash memory. This allows erase and write operations to proceed concurrently with CPU code execution - critical for over-the-air firmware updates, parameter logging, or secure key storage without interrupting real-time tasks.
