Product details
Overview
R5F10NPJDFB#35 from Renesas is a 100-pin LFQFP 32-bit RL78/I1C microcontroller with 256 KB flash, 16 KB RAM, hardware AES-128/192/256, independent-power-supply RTC, and 24-bit ΔΣ A/D converter - designed for electric AMI power meter applications requiring secure, ultra-low-power operation across –40°C to +85°C.
For engineers reviewing the R5F10NPJDFB#35 datasheet, R5F10NPJDFB#35 pinout, R5F10NPJDFB#35 application, or R5F10NPJDFB#35 equivalent, key selection considerations include its 100-pin LFQFP package, 256 KB code flash with security lock, dual-voltage domain LCD driver (up to 42 segments), and support for IrDA, LIN, UART, I²C, and CSI interfaces in industrial metering environments.
Technical Context
The R5F10NPJDFB#35 implements the RL78 CISC CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz PLL) to 66.6 µs (15 kHz low-speed oscillator). It integrates a dedicated 24-bit ΔΣ A/D converter with four channels, internal reference (1.45 V), and temperature sensor - all operable under single 1.9–5.5 V supply.
Its peripheral set includes an Event Link Controller (ELC) for 22-event routing, Data Transfer Controller (DTC) with chain transfer, independent-power-supply RTC with calendar/alarm/correction, and hardware AES engine compliant with GCM/ECB/CBC modes - all enabled without external crypto co-processors or RTC backup crystals.
