The R7F100GFL3CFP#HA0 operates up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy across VDD = 1.8–5.5 V and TA = −20 to +85°C. At lower frequencies (e.g., 16 MHz), it maintains full functionality down to VDD = 1.6 V, enabling flexible power/performance trade-offs in battery-powered designs.
Does the R7F100GFL3CFP#HA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GFL3CFP#HA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (up to 64 keys in 8×8 matrix) modes. It operates over VDD = 1.8–5.5 V and includes automatic noise cancellation and sensitivity tuning registers accessible via firmware.
How many UART, I²C, and SPI-compatible interfaces does the R7F100GFL3CFP#HA0 provide?
The R7F100GFL3CFP#HA0 provides up to 6 UARTA channels (including LIN-bus support), 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels. Pin multiplexing allows dynamic allocation across available GPIO, with hardware flow control and baud rate generation independent of CPU load.
What power-saving modes are available on the R7F100GFL3CFP#HA0, and what is the lowest achievable current draw?
The R7F100GFL3CFP#HA0 offers HALT, STOP, and SNOOZE modes. STOP mode draws 0.23 µA typical (210 nA RAM retention), while SNOOZE enables autonomous peripheral operation (e.g., ADC + compare + GPIO toggle) with no CPU or flash activity - ideal for intermittent sensing without wake-up latency.
Is the R7F100GFL3CFP#HA0 qualified for industrial temperature operation, and what is its specified ambient range?
Yes, the R7F100GFL3CFP#HA0 is rated for industrial applications (suffix "C") with an ambient operating temperature range of −40°C to +105°C, validated per JEDEC JESD22-A108.
