Product details
Overview
R5F101GDANA#20 from Renesas is a 20-pin HWQFN-packaged RL78/G13 16-bit microcontroller with no data flash, 128 KB code flash, 12 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (0.57 μA in RTC+LVD mode), and integrates 10-bit ADC (26 channels), RTC, UART, I²C, SPI, and 16-bit timers for embedded control in space-constrained industrial sensors and motor drives.
For engineers reviewing the R5F101GDANA#20 datasheet, R5F101GDANA#20 pinout, R5F101GDANA#20 application, or R5F101GDANA#20 equivalent, key selection criteria include its G-grade temperature rating (−40°C to +105°C), absence of data flash memory, HWQFN-20 (4 × 4 mm, 0.5-mm pitch) package, and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F101GDANA#20 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution time from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz low-speed mode). Its memory map spans 1 MB, and it supports background operation during data flash rewriting - though this part omits data flash entirely per its "101" prefix.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, HALT/STOP/SNOOZE low-power modes, and a high-accuracy ±1.0% on-chip oscillator (32 MHz max). Peripheral integration targets real-time control: 16-bit timer array (up to 16 channels), 12-bit interval timer, calendar RTC with alarm/correction, and dual UART/LIN support.

FAQ
What is the maximum operating frequency and performance of the R5F101GDANA#20?
The R5F101GDANA#20 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. Its RL78 CPU core supports configurable instruction timing - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed mode - enabling dynamic power/performance scaling. This makes the R5F101GDANA#20 suitable for deterministic real-time tasks such as motor commutation and sensor fusion.
Does the R5F101GDANA#20 include data flash memory?
No, the R5F101GDANA#20 does not include data flash memory. The "101" in its part number explicitly denotes zero data flash capacity, distinguishing it from "100"-series variants (e.g., R5F100GDANA#20) that integrate 8 KB of data flash. All nonvolatile storage is limited to the 128 KB code flash, which supports self-programming with boot swap functionality for firmware updates.
What package type and pin count does the R5F101GDANA#20 use?
The R5F101GDANA#20 uses a 20-pin HWQFN package (4 × 4 mm, 0.5-mm pitch) with an exposed thermal pad. This compact, surface-mount package is optimized for space-constrained applications such as motor driver modules and portable industrial sensors. Pin configuration follows the RL78/G13 20-pin layout, including shared functions like UART, SPI, I²C, ADC, and external interrupts on dedicated I/O lines.
What is the operating temperature range for the R5F101GDANA#20?
The R5F101GDANA#20 is rated for industrial operation from −40°C to +105°C (G-grade). This extended temperature range qualifies it for under-hood automotive applications, industrial motor drives, and outdoor sensor deployments where ambient conditions exceed standard commercial-grade limits. Thermal design must ensure junction temperature remains within specification under worst-case power dissipation.
Which development tools support the R5F101GDANA#20?
The R5F101GDANA#20 is fully supported by Renesas' E2 studio IDE, CS+ (formerly CubeSuite+), and the Renesas Flash Programmer. Hardware debugging uses the on-chip debug interface via TOOLRxD/TOOLTxD pins, compatible with Renesas E2 emulator Lite and E2 emulator. Reference designs and application notes for RL78/G13 - including motor control and sensor interface examples - are available on the Renesas website and apply directly to the R5F101GDANA#20.
