Product details
Overview
R5F100GLDNA#U0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), and real-time clock with calendar function - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GLDNA#U0 datasheet, R5F100GLDNA#U0 pinout, R5F100GLDNA#U0 application, or R5F100GLDNA#U0 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), on-chip debug support, self-programmable flash with boot swap, and hardware-accelerated multiply-accumulate for motor control firmware.
Technical Context
The R5F100GLDNA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock), and features a unified 1 MB address space with four register banks of eight 8-bit registers each.
It integrates dual power management domains: a main domain with HALT/STOP/SNOOZE low-power modes and a dedicated low-speed oscillator for watchdog and RTC operation; memory subsystem includes background operation (BGO) for data flash rewriting while executing code from program memory.

The R5F100GLDNA#U0 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0%), delivering 41 DMIPS. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction timing - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed 32.768 kHz mode - enabling flexible trade-offs between performance and power in the R5F100GLDNA#U0.
Does the R5F100GLDNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100GLDNA#U0 supports full in-system programming via its on-chip debug interface and includes flash shield window functionality to restrict read/write access to designated memory regions. It also implements boot swap capability, allowing validated firmware images to be loaded into inactive flash banks and atomically activated - ensuring robust, secure firmware updates in the R5F100GLDNA#U0.
What analog capabilities does the R5F100GLDNA#U0 provide for sensor interfacing?
The R5F100GLDNA#U0 integrates a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-die temperature sensor. It supports simultaneous sampling across multiple channels and operates across the full 1.6–5.5 V supply range - enabling direct interfacing with resistive, capacitive, and thermistor-based sensors without external signal conditioning in the R5F100GLDNA#U0.
How does the R5F100GLDNA#U0 manage ultra-low-power operation in battery-powered applications?
The R5F100GLDNA#U0 achieves 0.57 μA in STOP mode with RTC and LVD active, and 66 μA/MHz in active mode - enabled by multiple low-power states (HALT, STOP, SNOOZE), a dedicated low-speed oscillator for RTC/WDT, and automatic peripheral clock gating. Its voltage detector offers 14 programmable thresholds to trigger controlled shutdown before brown-out - extending operational life in battery-powered R5F100GLDNA#U0 deployments.
Is the R5F100GLDNA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GLDNA#U0 uses the 48-pin HWQFN package (PWQN0048KB-A) and shares identical pinout with all other RL78/G13 devices in that package variant - including R5F100GKDNA#U0 and R5F101GLDNA#U0. This allows drop-in replacement within the same memory/peripheral configuration tier, provided PCB layout accommodates the exposed thermal pad and decoupling requirements of the R5F100GLDNA#U0.
