For engineers reviewing the R5F51118AGFM#3A datasheet, R5F51118AGFM#3A pinout, R5F51118AGFM#3A application, or R5F51118AGFM#3A equivalent, key selection criteria include USB OTG support with BC charging, software standby mode recovery in 4.8 μs, 1.0 μs ADC conversion time, 64-pin LFQFP (PLQP0064KB-A) package compatibility, and IEC 60730 safety features including CAC and IWDT.

Technical Context

The R5F51118AGFM#3A implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates PLL, high-speed (32 MHz ±1%) and low-speed on-chip oscillators, sub-clock (32.768 kHz), and CAC for frequency accuracy validation.

Peripheral coordination is managed via Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention - critical for deterministic real-time response in motor control and USB device enumeration. The DTC supports chain transfers across four modes, while MTU2 provides six 16-bit timer channels with complementary PWM and phase counting for servo drive timing.

Yes, the R5F51118AGFM#3A integrates a USB 2.0 host/function module that fully supports OTG and BC 1.2 detection. It identifies SDP, CDP, and DCP chargers in hardware without host software intervention, and enables seamless role switching between USB host and device modes - a capability confirmed in the R01DS0190EJ0130 datasheet for the R5F51118AGFM#3A.

What are the low-power modes supported by the R5F51118AGFM#3A and their typical current consumption?

The R5F51118AGFM#3A supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode - the lowest-power active state - it draws just 0.44 μA while maintaining RTC operation and retaining SRAM contents. Wake-up latency from this mode is 4.8 μs, allowing rapid response to external events - a verified specification for the R5F51118AGFM#3A under −40°C to +105°C conditions.
