For engineers reviewing the R5F51118AGNE#2A datasheet, R5F51118AGNE#2A pinout, R5F51118AGNE#2A application, or R5F51118AGNE#2A equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases, and validated alternative parts - all grounded in Renesas' official R01DS0190EJ0130 Rev.1.30 documentation.
Technical Context
The R5F51118AGNE#2A implements a CISC Harvard-architecture RX CPU core with five-stage pipeline, variable-length instructions, and on-chip debugging support. It integrates an Event Link Controller (ELC) enabling direct module-to-module triggering without CPU intervention, and a Data Transfer Controller (DTC) supporting chain transfers across four modes.
Its clock system includes a high-speed on-chip oscillator (32 MHz ±1% over −40°C to +105°C), PLL, sub-clock (32.768 kHz), and Clock Accuracy Measurement Circuit (CAC) for IEC 60730 compliance. Power management supports software standby mode (0.44 μA) with 4.8 μs wake-up and three low-power modes.

Yes, the R5F5118AGNE#2A integrates a USB 2.0 host/function/OTG module supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) operation. It includes hardware BC (Battery Charger) detection and isochronous transfer support. The R5F51118AGNE#2A requires no external PHY - its on-chip transceiver drives USB0_DP and USB0_DM directly, simplifying board design for embedded USB host applications.
How many A/D and D/A channels does the R5F51118AGNE#2A provide, and what are their resolutions?
The R5F51118AGNE#2A includes a 12-bit successive-approximation A/D converter with up to 14 input channels (AN000–AN004, AN006, AN008–AN015) and a minimum conversion time of 1.0 μs. It also provides two 8-bit voltage-output D/A channels (DA0, DA1), available specifically on 48-pin and larger packages like the PWQN0048KB-A used by R5F51118AGNE#2A.
Is the R5F51118AGNE#2A supported for IEC 60730 functional safety compliance?
Yes, the R5F51118AGNE#2A includes dedicated hardware for IEC 60730 Class B compliance: a Clock Accuracy Measurement Circuit (CAC), Independent Watchdog Timer (IWDT) with dedicated 15 kHz oscillator, RAM test assist functions, and voltage monitoring circuits. These features are documented in Renesas' R01DS0190EJ0130 and reduce certification effort for household and industrial appliances.
