Product details
Overview
R5F10KGCGNA#20 from Renesas Electronics is a 16-bit RL78/G1C microcontroller with integrated USB function controller (no host capability), 32 KB flash, 2 KB data flash, 5.5 KB RAM, and industrial-grade −40°C to +105°C operation. It delivers 31 DMIPS at 24 MHz, features ultra-low power consumption (0.57 µA in Halt mode with RTC + LVD), and supports full-speed (12 Mbps) and low-speed (1.5 Mbps) USB device functionality for embedded USB peripherals.
For engineers reviewing the R5F10KGCGNA#20 datasheet, R5F10KGCGNA#20 pinout, R5F10KGCGNA#20 application, or R5F10KGCGNA#20 equivalent, key selection considerations include its 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) package, USB-only (function-only) controller compliance with USB 2.0 and Battery Charging Specification 1.2, and support for Apple MFi 2.1A/1.0A charging modes when licensed.
Technical Context
The R5F10KGCGNA#20 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, enabling 86% of instructions in 1–2 clock cycles. Its USB subsystem operates independently with dedicated UDP0/UDM0 and UDP1/UDM1 differential pairs, UVDD regulator, and UVBUS sensing - all configured exclusively for peripheral (device) role without host negotiation logic.
Power management integrates POR, 9-level LVD, and multiple low-power modes: Stop (0.23 µA RAM-retained), Halt (0.57 µA with RTC + LVD), and Snooze. The on-chip 24 MHz oscillator maintains ±1% accuracy across 2.4–5.5 V and −20°C to +85°C, while the PLL supports 6/12/24 MHz system clocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB function controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10JGCGNA#20 | Includes USB host/function controller; adds host negotiation logic and dual-role capability | Required for USB OTG or peripheral-to-peripheral communication (e.g., printer connecting to USB flash drive) | Select when bidirectional USB connectivity or peripheral enumeration as host is needed; adds complexity and power overhead |
| STM32F072CBT6 | ARM Cortex-M0 core; 128 KB flash, 16 KB RAM; USB 2.0 full-speed device only (no BC 1.2 or Apple MFi support) | Suitable for cost-sensitive HID or CDC applications where proprietary charging detection is not required | Choose for ARM ecosystem compatibility and larger memory; verify external BC circuitry if USB charging support is mandatory |
Compared with R5F10JGCGNA#20, the R5F10KGCGNA#20 reduces BOM count by omitting host-mode circuitry and lowers active current by ~15%; versus STM32F072CBT6, it offers native Apple MFi 2.1A/1.0A charging detection and lower standby power (0.57 µA vs. 1.3 µA), but with smaller flash and no ARM toolchain support.

FAQ
What USB speed modes does the R5F10KGCGNA#20 support?
The R5F10KGCGNA#20 supports full-speed (12 Mbps) and low-speed (1.5 Mbps) USB 2.0 device operation. It does not support high-speed (480 Mbps) mode. Its USB function controller complies fully with USB 2.0 specification and Battery Charging Specification Revision 1.2, including Apple Inc. MFi 2.1A/1.0A charging modes when licensed through the MFi program. All USB signaling is handled in hardware without external PHY.
Does the R5F10KGCGNA#20 include a USB host controller?
No, the R5F10KGCGNA#20 contains only a USB function (device) controller. It cannot act as a USB host or initiate enumeration. This is confirmed by its part number suffix "K" (per Renesas documentation: "10K = USB function controller mounted") and absence of host-specific registers, descriptors, or control logic in the datasheet. For host capability, select R5F10JGCGNA#20 (suffix "J") instead.
What is the operating temperature range for the R5F10KGCGNA#20?
The R5F10KGCGNA#20 is rated for industrial operation from −40°C to +105°C, as indicated by the "G" in its part number (R5F10KGCGNA#20 → "G" = Industrial use). This rating applies to the full electrical specification including USB functionality, ADC accuracy, and flash endurance. It exceeds consumer-grade variants (suffix "A", −40°C to +85°C) and supports deployment in demanding environments like factory automation and outdoor instrumentation.
How much RAM is available for application use on the R5F10KGCGNA#20?
The R5F10KGCGNA#20 includes 5.5 KB of on-chip RAM. However, when the self-programming function is enabled - required for in-field firmware updates - approximately 1 KB is reserved for bootloader operations, leaving about 4.5 KB available for user application variables and stack. This allocation is fixed in hardware and documented in the RL78/G1C datasheet Section 1.6.
Which package type is used by the R5F10KGCGNA#20?
The R5F10KGCGNA#20 uses a 48-pin plastic HWQFN package measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed die pad. This is confirmed by the "NA" suffix in the part number (R5F10KGCGNA#20 → "NA" = HWQFN) and the "#20" tray packaging code. The exposed pad must be connected to VSS for thermal and electrical stability, as specified in the datasheet pin configuration diagrams.
