Product details
Overview
R5F10EBCGNA#20 from Renesas Electronics is a 32-pin HWQFN-packaged 16 KB Flash, 2 KB RAM RL78/G1A 16-bit microcontroller with 12-bit ADC (18 channels), 32 MHz max CPU frequency (41 DMIPS), and ultra-low power operation down to 0.57 µA in RTC+LVD mode. It targets battery-powered industrial sensor nodes and smart metering interfaces requiring precise analog acquisition and long-term autonomous operation.
For engineers reviewing the R5F10EBCGNA#20 datasheet, R5F10EBCGNA#20 pinout, R5F10EBCGNA#20 application, or R5F10EBCGNA#20 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm) package, industrial-grade −40 °C to +105 °C operating range, integrated 4 KB data flash with 1 million erase cycles, and dual UART/I²C/CSI peripheral support for multi-protocol fieldbus interfacing.
Technical Context
The R5F10EBCGNA#20 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 clock cycles. Its on-chip high-speed oscillator delivers 32 MHz ±1% accuracy across 1.8–3.6 V and −20 °C to +85 °C, enabling precise timing without external crystals in many applications.
It integrates a 12-bit ADC with 3.375 µs conversion time, internal 1.45 V reference, and support for 1.6 V analog supply. Safety features include flash CRC, RAM parity check, SFR write protection, and illegal memory access detection-aligned with IEC/UL 60730 requirements for industrial control.
