Renesas R5F10JGCGNA#20

Overview

R5F10JGCGNA#20 from Renesas Electronics is a 48-pin industrial-grade RL78/G1C 16-bit 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 delivers 31 DMIPS at 24 MHz, supports full-speed USB 2.0 (12 Mbps), and targets embedded USB peripheral devices such as industrial sensors and USB-powered control modules.

For engineers reviewing the R5F10JGCGNA#20 datasheet, R5F10JGCGNA#20 pinout, R5F10JGCGNA#20 application, or R5F10JGCGNA#20 equivalent, key selection criteria include its 48-pin HWQFN package, USB VBUS sensing (UOVRCUR0/UVBUSEN0), dual I²C interfaces, 9-channel 10-bit ADC, and −40°C to +105°C industrial temperature rating.

Technical Context

The R5F10JGCGNA#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 with USB 2.0 specification and Battery Charging Specification Rev. 1.2, supporting both full-speed (12 Mbps) and low-speed (1.5 Mbps) modes with Apple MFi 2.1A/1.0A charging mode capability.

Power management includes multiple low-power modes: Stop (0.23 µA RAM-retained), Halt (0.57 µA with RTC + LVD), and Snooze mode. The high-speed on-chip oscillator provides 24 MHz ±1% accuracy across 2.4–5.5 V and −20°C to +85°C, while PLL enables 24 MHz system clock from internal or external sources.

FAQ

What USB specifications does the R5F10JGCGNA#20 support?

The R5F10JGCGNA#20 supports USB 2.0 full-speed (12 Mbps) and low-speed (1.5 Mbps) operation, Battery Charging Specification Revision 1.2, and Apple Inc. MFi 2.1A/1.0A charging modes. It integrates both host and function controller logic, eliminating the need for an external USB transceiver. USB signaling uses dedicated UDP0/UDM0 pins with internal termination and slew-rate control.

Does the R5F10JGCGNA#20 include hardware safety features for industrial use?

Yes, the R5F10JGCGNA#20 includes multiple hardware safety mechanisms required for IEC/UL 60730 Class B compliance: 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 (echo) functionality-all implemented in hardware without software overhead.

What is the operating voltage range and low-power performance of the R5F10JGCGNA#20?

The R5F10JGCGNA#20 operates from 2.4 V to 5.5 V and achieves 0.57 µA in Halt mode with RTC and LVD active, 0.23 µA in Stop mode with RAM retention, and 71 µA/MHz during active operation. Its high-speed on-chip oscillator maintains ±1% accuracy across the full voltage and temperature range, enabling reliable timing without external crystals in many applications.

How many analog input channels and what ADC resolution does the R5F10JGCGNA#20 provide?

The R5F10JGCGNA#20 integrates a 9-channel, 10-bit successive-approximation ADC with a minimum conversion time of 2.1 µs. Input channels include ANI0–ANI7, ANI16, ANI17, and ANI19. It supports selectable reference voltages: internal 1.45 V, AVREFP/AVREFM pins, or VDD, and includes an on-chip temperature sensor for system-level thermal monitoring.

What package type and pin count does the R5F10JGCGNA#20 use?

The R5F10JGCGNA#20 uses a 48-pin plastic HWQFN package (7 × 7 mm, 0.5 mm pitch) with an exposed die pad recommended for connection to VSS. This compact, thermally efficient package supports high-density PCB layouts and is optimized for automated assembly in industrial manufacturing environments.
