Product details
Overview
R5F10NMGDFB#30 from Renesas is an 80-pin LFQFP RL78/I1C 16-bit MCU with 128 KB flash, 8 KB RAM, 2 KB data flash, hardware AES encryption, independent-power-supply RTC, and 24-bit ΔΣ A/D converter - designed for electric AMI power meter applications requiring ultra-low power operation (1.9–5.5 V), secure firmware storage, and high-precision metrology.
For engineers reviewing the R5F10NMGDFB#30 datasheet, R5F10NMGDFB#30 pinout, R5F10NMGDFB#30 application, or R5F10NMGDFB#30 equivalent, key selection criteria include its 80-pin LFQFP package, AES-128/192/256 support, RTC with calendar/alarm/correction, 3-channel ΔΣ ADC (24-bit), and industrial temperature range (−40°C to +85°C).
Technical Context
The R5F10NMGDFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable clock sources including PLL (32 MHz), high-speed on-chip oscillator (up to 24 MHz ±1.0%), and low-speed on-chip oscillator (15 kHz). It supports HALT, STOP, and SNOOZE low-power modes with dedicated RTC power domain (VRTC) and battery backup capability.
Its peripheral set includes 8× 16-bit timer channels, UART0–2 (LIN-capable), simplified SPI/CSI (3 channels), simplified I²C (3 channels), full I²C (1 channel), IrDA interface, LCD controller (34 segments, 8 commons), and Event Link Controller (ELC) for hardware-triggered peripheral chaining - all optimized for secure, low-power smart metering systems.

FAQ
What is the maximum operating frequency of the R5F10NMGDFB#30?
The R5F10NMGDFB#30 supports a maximum CPU clock frequency of 32 MHz via its integrated PLL. This is achieved with the PLL clock source enabled and is fully compatible with all on-chip peripherals, including the 24-bit ΔΣ A/D converter, which remains operational at this clock rate per the R01DS0281EJ0231 datasheet.
Does the R5F10NMGDFB#30 include hardware AES acceleration?
Yes, the R5F10NMGDFB#30 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" section and is exclusive to the R5F10N-series variants, distinguishing it from the R5F11T-series which lacks this feature.
What is the RTC power domain configuration for the R5F10NMGDFB#30?
The R5F10NMGDFB#30 features an independent RTC power domain supplied via the VRTC pin, decoupled from the main VDD rail. It supports battery backup through the VBAT pin and includes an RTC power-on-reset (RTCPOR) circuit - enabling continuous timekeeping and calendar functionality during main power failure, as specified in Section 1.1 of the R01DS0281EJ0231 datasheet.
How many channels does the ΔΣ A/D converter have on the R5F10NMGDFB#30?
The R5F10NMGDFB#30 integrates a 24-bit ΔΣ A/D converter with three dedicated channels (ΔΣ ADC0–ADC2), as confirmed in the "1.5.2 80-pin products" block diagram (Page 11) and Table 1-1 functional overview. A fourth channel (ΔΣ ADC3) is present but not enabled in 80-pin variants - only 64- and 100-pin versions support four channels.
What package type and pin count does the R5F10NMGDFB#30 use?
The R5F10NMGDFB#30 uses an 80-pin plastic LFQFP package (12 × 12 mm, 0.5 mm pitch), designated by the "M" in the part number and confirmed in Table 1-1 of the R01DS0281EJ0231 datasheet. The "FB" suffix explicitly denotes LFQFP with 0.50 mm pitch, and "#30" indicates tray packaging per Version 1.0 specification.
