FAQ
What is the maximum operating frequency and power supply range for the R5F51113ADNE#2A?
The R5F51113ADNE#2A operates at a maximum frequency of 32 MHz with a supply voltage range of 1.8 V to 3.6 V. Frequency scaling is voltage-dependent: 8 MHz at 1.8–2.4 V, 16 MHz at 2.4–2.7 V, and full 32 MHz above 2.7 V. This ensures deterministic performance across varying battery or rail conditions while maintaining 50 DMIPS throughput at peak speed.
Does the R5F51113ADNE#2A support USB On-The-Go (OTG) functionality?
Yes, the R5F51113ADNE#2A includes a USB 2.0 host/function module compliant with OTG specification. It supports full-speed (12 Mbps) and low-speed (1.5 Mbps) operation, isochronous transfers, and Battery Charging (BC) detection. The USB0_ID pin enables OTG role negotiation, and USB0_EXICEN/USB0_VBUSEN manage external OTG chip power control.
How many A/D and D/A converter channels does the R5F51113ADNE#2A provide?
The R5F51113ADNE#2A integrates a 12-bit successive approximation register (SAR) A/D converter with up to 14 input channels (AN000–AN015, excluding AN005/AN007), and two 8-bit voltage-output D/A converters (DA0, DA1). The A/D supports double-trigger mode for synchronized sampling, and the DACs deliver rail-to-rail output from 0 V to VCC with monotonicity guaranteed.
What low-power modes are available on the R5F51113ADNE#2A, and what is the lowest current draw?
The R5F51113ADNE#2A offers three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode, current consumption drops to 0.44 μA while retaining RTC operation and wake-up capability via external interrupt or RTC alarm. Recovery time from this state is 4.8 μs, enabling rapid responsiveness to events without sacrificing energy efficiency.
Is the R5F51113ADNE#2A pin-compatible with other RX111 Group members in the same package?
Yes, all RX111 Group MCUs in the PWQN0048KB-A (HWQFN-48) package share identical pin assignments and electrical characteristics. This includes variants like R5F51113AGNE#UA (−40°C to +105°C), R5F51114ADNE#UA (96 KB flash), and R5F51111ADNE#UA (32 KB flash). Firmware and PCB layouts are interchangeable across these parts, simplifying scalability and temperature grade migration.
