Product details
Overview
R5F100GLDNA#20 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and DMA - deployed in industrial motor control and sensor interface modules.
For engineers reviewing the R5F100GLDNA#20 datasheet, R5F100GLDNA#20 pinout, R5F100GLDNA#20 application, or R5F100GLDNA#20 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), HWQFN-compatible 48-pin LFQFP package (FB), integrated data flash with 1M rewrite cycles, real-time clock with calendar/alarm, and support for background data flash programming during code execution.
Technical Context
The R5F100GLDNA#20 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It supports multiple low-power modes - HALT, STOP, and SNOOZE - with on-chip POR and LVD (14-level selectable).
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, one real-time clock with calendar and clock correction, one watchdog timer, and three serial interfaces (CSI, UART/LIN, I²C) configurable across 2–10 channels. The 10-bit A/D converter supports up to 26 analog inputs with internal 1.45 V reference and temperature sensor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GLDFA#V0 | Same core, memory, and peripherals; differs only in packaging (48-pin LQFP, 0.65 mm pitch) and temperature grade (D: -40°C to +85°C) | Targeted at commercial/industrial ambient applications without extended temperature requirement | Select when board layout uses standard 0.65 mm pitch LQFP footprints and ambient temperature stays ≤ +85°C |
| R5F101GLDNA#20 | Identical package and pinout, but lacks data flash (0 KB); retains same code flash, RAM, and peripheral set | Suitable where firmware-only storage is sufficient and data logging or parameter retention is handled externally | Choose to reduce cost and simplify qualification when non-volatile parameter storage is not required on-chip |
Compared with R5F100GLDNA#20, R5F100GLDFA#V0 offers identical functionality at lower thermal rating and different footprint, while R5F101GLDNA#20 removes data flash to cut cost - making the former ideal for volume consumer designs and the latter for firmware-only embedded controllers.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GLDNA#20?
The R5F100GLDNA#20 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - enabling flexible trade-offs between throughput and energy efficiency in the R5F100GLDNA#20.
Does the R5F100GLDNA#20 support in-system programming and secure firmware updates?
Yes, the R5F100GLDNA#20 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features for security. It implements self-programming with boot swap functionality, allowing safe over-the-air or field firmware updates without risk of corruption - a core capability built into the R5F100GLDNA#20's flash controller.
What are the key low-power modes supported by the R5F100GLDNA#20, and what functions remain active in each?
The R5F100GLDNA#20 supports HALT, STOP, and SNOOZE modes. In STOP mode (0.57 μA), the RTC and LVD remain fully operational; in HALT mode, the CPU stops but peripherals continue; SNOOZE enables selective peripheral operation (e.g., ADC conversion or UART receive) while CPU sleeps. All modes are accessible directly in the R5F100GLDNA#20 without external components.
Can the R5F100GLDNA#20 interface directly with 1.8 V or 2.5 V logic devices?
Yes, the R5F100GLDNA#20 supports different-potential interface operation: its I/O ports can be configured to interface with 1.8 V, 2.5 V, or 3 V external devices without level shifters. This is achieved through independent VDDIO configuration and input buffer design - a verified feature of the R5F100GLDNA#20 per its electrical specifications.
Is the R5F100GLDNA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin LFQFP (FB) package - including R5F100GLDNA#20, R5F100GLDFA#V0, and R5F101GLDNA#20 - share identical pinouts and mechanical footprint. This enables hardware reuse across memory, temperature grade, and data flash variants - a documented compatibility guarantee for the R5F100GLDNA#20 within its package family.
