Overview
R5F10NMEDFB#35 from Renesas is an RL78/I1C 80-pin ultra-low-power 16-bit MCU with 64 KB code flash, 2 KB data flash, 8 KB RAM, hardware AES-128/192/256, independent RTC powered by VRTC, and integrated 24-bit ΔΣ A/D converter - designed specifically for electric AMI power meter applications requiring secure firmware, long battery life, and high-precision metrology.
For engineers reviewing the R5F10NMEDFB#35 datasheet, R5F10NMEDFB#35 pinout, R5F10NMEDFB#35 application, or R5F10NMEDFB#35 equivalent, this page delivers verified technical context, real-world use cases in utility metering, exact package mapping (LFQFP-80), validated pin functions, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The R5F10NMEDFB#35 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable minimum instruction time of 0.03125 µs (32 MHz PLL) or 66.6 µs (15 kHz low-speed oscillator). It integrates a dedicated 24-bit ΔΣ A/D converter with 3 channels, 10-bit SAR A/D with 4 channels, and supports background operation during data flash rewriting.
Its power architecture includes HALT, STOP, and SNOOZE modes; on-chip POR, RTCPOR, and 13-level LVD; and independent VRTC supply with calendar function (99-year range), alarm, and clock correction. The AES engine supports GCM/ECB/CBC modes and operates across VDD = 1.9–5.5 V.

FAQ
What is the maximum operating frequency of the R5F10NMEDFB#35?
The R5F10NMEDFB#35 supports a maximum CPU clock of 32 MHz using the on-chip PLL. This frequency is achievable with VDD ≥ 2.8 V and enables a minimum instruction execution time of 0.03125 µs. The high-speed on-chip oscillator also supports up to 24 MHz (±1.0% accuracy) across the full VDD range of 1.9–5.5 V.
Does the R5F10NMEDFB#35 include hardware AES acceleration?
Yes, the R5F10NMEDFB#35 includes a dedicated hardware AES circuit supporting GCM, ECB, and CBC cipher modes with 128-, 192-, and 256-bit key lengths. This capability is confirmed in the datasheet's "AES circuit" note and applies specifically to all R5F10N-series devices, including R5F10NMEDFB#35.
What is the ADC configuration supported by the R5F10NMEDFB#35?
The R5F10NMEDFB#35 integrates two ADC subsystems: a 24-bit ΔΣ A/D converter with 3 input channels (ANIP0–ANIP2/ANIN0–ANIN2) and a 10-bit SAR A/D converter with 4 channels (ANI0–ANI3). Both share internal reference (1.45 V) and temperature sensing, and the ΔΣ ADC supports background operation during flash writes.
What package type and pin count does the R5F10NMEDFB#35 use?
The R5F10NMEDFB#35 uses an 80-pin plastic LFQFP package (12 × 12 mm, 0.5 mm pitch), designated by "M" in the part number and "FB" suffix. The #35 suffix indicates Ver.1.1 tray packaging per Renesas' ordering convention, and it is fully compatible with standard LFQFP-80 reflow profiles.
Is the RTC in the R5F10NMEDFB#35 truly independent of the main power supply?
Yes, the R5F10NMEDFB#35 features an independent power supply RTC with dedicated VRTC and REGC pins. When VRTC is supplied (1.6–5.5 V), the RTC maintains calendar, alarm, and correction functions even if VDD is completely removed - enabling uninterrupted timekeeping in battery-backed metering applications.
