Product details
Overview
R5F10JBCGNA#20 from Renesas Electronics is a 32-pin, industrial-grade 16-bit RL78/G1C microcontroller with integrated USB host/function controller, 32 KB flash, 5.5 KB RAM, and true low-power operation (0.57 µA in Halt mode with RTC + LVD). It operates from 2.4 V to 5.5 V, delivers 31 DMIPS at 24 MHz, and targets USB-powered embedded control in industrial sensing, portable instrumentation, and battery-backed human interface devices.
For engineers reviewing the R5F10JBCGNA#20 datasheet, R5F10JBCGNA#20 pinout, R5F10JBCGNA#20 application, or R5F10JBCGNA#20 equivalent, this page provides verified technical context, package-validated pin functions, USB timing and power delivery specifications, low-power state behavior, and real-world application constraints for industrial temperature deployment.
Technical Context
The R5F10JBCGNA#20 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 complies fully with USB 2.0 specification, supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, Battery Charging Specification Rev. 1.2, and Apple MFi 2.1A/1.0A charging modes when licensed.
Power management includes dual oscillators (24 MHz ±1% on-chip HOCO; 32.768 kHz XTAL for RTC), POR/LVD with 9 voltage thresholds, and four low-power modes: Stop (0.23 µA RAM-retained), Halt (0.57 µA RTC+LVD), Snooze, and Operating (71 µA/MHz). The 16-bit TAU timer supports remote control output, while the 8/10-bit ADC offers 9 channels with 2.1 µs min conversion time.

FAQ
What USB power delivery capabilities does the R5F10JBCGNA#20 support?
The R5F10JBCGNA#20 supports USB Battery Charging Specification Revision 1.2 and Apple MFi 2.1A/1.0A charging modes when properly licensed. Its UVBUS, UOVRCUR0/1, and UVBUSEN0/1 pins enable overvoltage/overcurrent protection and dynamic port power switching-allowing the R5F10JBCGNA#20 to act as a self-powered USB hub or charger controller without external PMICs.
How does the R5F10JBCGNA#20 achieve 0.57 µA Halt mode current?
The R5F10JBCGNA#20 achieves 0.57 µA Halt mode by disabling the CPU, flash, and most peripherals while retaining RTC oscillator, LVD circuitry, and SRAM contents. This state is entered via software command and maintained using the low-speed on-chip oscillator (15 kHz), with only essential bias currents active-enabling multi-year operation on coin-cell batteries in always-on monitoring applications.
Can the R5F10JBCGNA#20 operate without an external crystal?
Yes, the R5F10JBCGNA#20 can operate entirely from its internal 24 MHz high-speed on-chip oscillator (HOCO) with ±1% accuracy across 2.4–5.5 V and −40°C to +105°C. External crystals (X1/X2) are optional and used only when higher precision (e.g., for USB SOF timing or RTC calibration) is required-reducing BOM cost and board space for many industrial control applications.
What safety certifications does the R5F10JBCGNA#20 support for industrial use?
The R5F10JBCGNA#20 includes hardware-level safety features aligned with IEC/UL 60730 Class B requirements: flash memory CRC calculation, RAM parity error detection, SFR write protection, illegal memory access detection, clock stop/frequency monitoring, ADC self-test, and I/O port read-back verification-all accessible via documented register interfaces without external components.
Is the R5F10JBCGNA#20 pin-compatible with other RL78/G1C variants?
The R5F10JBCGNA#20 shares identical pinout and function mapping with all 32-pin RL78/G1C devices in HWQFN packaging-including R5F10JBCANA#20 and R5F10KBCGNA#20-enabling drop-in replacement for USB host/function capability upgrades or temperature grade changes without PCB revision.
