Product details
Overview
R5F10NMEDFB#30 from Renesas is an RL78/I1C 80-pin ultra-low-power 16-bit MCU with 128 KB flash, 8 KB RAM, hardware AES-128/192/256, independent RTC (VRTC), and 24-bit ΔΣ A/D converter - designed specifically for electric AMI power meter applications requiring secure metering, long battery life, and high-precision energy measurement.
For engineers reviewing the R5F10NMEDFB#30 datasheet, R5F10NMEDFB#30 pinout, R5F10NMEDFB#30 application, or R5F10NMEDFB#30 equivalent, this part delivers verified low-voltage operation (1.9–5.5 V), industrial temperature range (−40°C to +85°C), integrated LCD driver (34 segments), and dual UART/LIN support critical for smart meter firmware development and certification.
Technical Context
The R5F10NMEDFB#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 sub-μA RTC backup current.
Its peripheral set includes a 24-bit ΔΣ A/D converter (3 channels), 10-bit SAR A/D (4 channels), 8-channel 16-bit timer array, event link controller (ELC) for autonomous peripheral triggering, data transfer controller (DTC), and hardware AES engine supporting GCM/ECB/CBC modes - all operating under single-supply voltage without external regulators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RL78 16-bit CISC CPU with 3-stage pipeline; enables deterministic real-time response in meter firmware with minimal code footprint. |
| Flash / RAM | 128 KB code flash + 2 KB data flash + 8 KB RAM; sufficient for dual-application firmware (metering + communication stack) with BGO data flash rewriting. |
| Operating Voltage | 1.9 V to 5.5 V; supports direct connection to lithium battery (3.0–3.6 V) and AC-derived rails without level-shifting or LDOs. |
| ΔΣ A/D Converter | 24-bit resolution, 3-channel; provides >100 dB SNR for precision active/reactive energy measurement per IEC 62053-21/22. |
| AES Engine | Hardware AES-128/192/256 with GCM mode; enables authenticated encryption of meter data for DLMS/COSEM compliance without CPU overhead. |
| RTC | Independent power supply RTC (VRTC); maintains calendar, alarm, and correction functions during main power loss using VBAT backup. |
| Package | 80-pin LFQFP (12 × 12 mm, 0.5 mm pitch); compatible with standard reflow profiles and supports high-density meter PCB layouts. |
Pinout & Package
80-pin plastic LFQFP (12 × 12 mm, 0.5 mm pitch) with exposed pad not specified; REGC requires 0.47–1 µF capacitor to VSS per datasheet caution.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
