Its RX CPU core features a five-stage pipeline, 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations, and ultra-compact variable-length instruction encoding - enabling efficient code density and deterministic real-time execution critical for R5F51118ADFL#3A-based control applications.
Does the R5F51118ADFL#3A support USB On-The-Go (OTG) functionality?
Yes, the R5F51118ADFL#3A integrates a USB 2.0 host/function module compliant with OTG specification, supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) operation, isochronous transfers, and Battery Charging (BC) 1.2 detection. The R5F51118ADFL#3A uses USB0_ID, USB0_VBUS, and USB0_EXICEN pins to manage role switching and power negotiation - eliminating need for external OTG PHY or controller.
What low-power modes are available on the R5F51118ADFL#3A, and what is the lowest supply current?
The R5F51118ADFL#3A supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it draws just 0.44 μA (typical) while retaining SRAM content and waking in 4.8 μs - ideal for battery-powered sensor nodes. The R5F51118ADFL#3A achieves this via clock gating, peripheral stop control, and retention of critical registers during standby, all managed through the LPMCR register set.

The R5F51118ADFL#3A includes a 12-bit successive-approximation ADC with up to 14 input channels (AN000–AN004, AN006, AN008–AN015). At 32 MHz ADCLK, its minimum conversion time is 1.0 μs per channel. The R5F51118ADFL#3A also supports double-trigger mode for motor control and flexible start sources including software, MTU timers, external pins, or ELC events - ensuring precise timing-critical sampling.
Is the R5F51118ADFL#3A pin-compatible with other members of the RX111 Group?
Yes, the R5F5118ADFL#3A shares identical pinout and electrical characteristics with other 48-pin RX111 variants in the PLQP0048KB-A package (e.g., R5F51116ADFL#3A, R5F51117ADFL#3A). All 48-pin RX111 MCUs use the same footprint, signal mapping, and power sequencing - allowing direct substitution within the same package family without PCB revision, provided firmware and memory requirements align with the selected variant's flash/RAM capacity.
