Product details
Overview
R5F10KBCGNA#U0 from Renesas Electronics is a 32-pin, industrial-grade 16-bit RL78/G1C microcontroller with integrated USB function controller (no host capability), 32 KB flash, 5.5 KB RAM, and true low-power operation down to 0.57 µA in Halt mode (RTC + LVD). It operates from 2.4 V to 5.5 V, delivers 31 DMIPS at 24 MHz, and targets USB-powered embedded devices requiring battery longevity and robust real-time control - such as smart sensors, portable medical monitors, and industrial USB peripherals.
For engineers reviewing the R5F10KBCGNA#U0 datasheet, R5F10KBCGNA#U0 pinout, R5F10KBCGNA#U0 application, or R5F10KBCGNA#U0 equivalent, key selection criteria include its USB-only (function-only) interface compliance with USB 2.0 full-speed (12 Mbps), Apple MFi 2.1A/1.0A charging support, 9-channel 8/10-bit ADC, and 32-pin HWQFN (5 × 5 mm, 0.5 mm pitch) package with exposed die pad.
Technical Context
The R5F10KBCGNA#U0 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and CISC instruction set enabling 86% of instructions in 1–2 clock cycles. Its USB subsystem is strictly function-only (no host controller), compliant with USB 2.0, Battery Charging Specification Rev. 1.2, and Apple MFi power delivery modes - all enabled via dedicated UDP0/UDM0/UVBUS/UVDD pins and internal USB voltage regulator.
Power management includes three low-power modes: Stop (0.23 µA RAM-retained), Halt (0.57 µA RTC+LVD), and Snooze; clocking supports high-speed on-chip oscillator (24 MHz ±1% over voltage/temperature), PLL (up to 24 MHz), and subsystem crystal (32.768 kHz). Safety features include RAM parity check, flash CRC, illegal memory access detection, and I/O port read-back echo.

FAQ
What USB capabilities does the R5F10KBCGNA#U0 support?
The R5F10KBCGNA#U0 integrates a USB function-only controller compliant with USB 2.0 full-speed (12 Mbps) and low-speed (1.5 Mbps) modes. It supports Battery Charging Specification Rev. 1.2 and Apple MFi 2.1A/1.0A charging modes via UVBUS sense and UVDD regulation. Unlike R5F10JBC variants, it lacks USB host functionality and related pins (UDP1/UDM1, UOVRCURx, UVBUSENx).
Does the R5F10KBCGNA#U0 include a hardware RTC with calendar function?
Yes, the R5F10KBCGNA#U0 includes a full-calendar real-time clock (RTC) with alarm and watch correction functions, driven by the 32.768 kHz subsystem clock. The RTC operates in Halt mode (0.57 µA) and retains timekeeping while preserving RAM contents - critical for timestamped logging in battery-powered USB peripherals.
What is the maximum ADC resolution and channel count supported by the R5F10KBCGNA#U0?
The R5F10KBCGNA#U0 supports an 8/10-bit successive approximation ADC with up to 9 input channels (ANI0–ANI4, ANI16–ANI19). Conversion time is as low as 2.1 µs, and the module includes internal 1.45 V reference voltage and AVREFP/AVREFM pins for precise ratiometric measurements - essential for sensor signal conditioning.
How does the R5F10KBCGNA#U0 achieve ultra-low power consumption in Halt mode?
The R5F10KBCGNA#U0 achieves 0.57 µA Halt-mode current by retaining only RTC and low-voltage detector (LVD) circuitry while shutting down CPU, flash, and most peripherals. This mode maintains accurate timekeeping and brown-out monitoring without external components - enabling multi-year battery life in USB-wake-on-connect applications.
Is the R5F10KBCGNA#U0 pin-compatible with other RL78/G1C variants in the same package?
No - the R5F10KBCGNA#U0 is not pin-compatible with R5F10JBCGNA#U0 despite sharing the 32-pin HWQFN package. Key differences include omission of USB overcurrent/enable pins (UOVRCUR0/1, UVBUSEN0/1) and second USB differential pair (UDP1/UDM1) in the KBC variant. PCB layout must be specific to R5F10KBCGNA#U0's pin assignment.
