Product details
Overview
R5F100GLDFB#X0 from Renesas is a 48-pin LFQFP (7 × 7 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and operation up to 32 MHz (41 DMIPS). It features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, UART/SPI/I²C interfaces, and operates from −40°C to +105°C.
For engineers reviewing the R5F100GLDFB#X0 datasheet, R5F100GLDFB#X0 pinout, R5F100GLDFB#X0 application, or R5F100GLDFB#X0 equivalent, key selection considerations include its industrial temperature rating, on-chip data flash rewrite endurance (1M cycles), background operation capability during program execution, and support for multiple low-power modes (HALT/STOP/SNOOZE) in compact LFQFP-48 packaging.
Technical Context
The R5F100GLDFB#X0 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). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB SRAM - all accessible within a 1 MB address space.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock (RTC), one watchdog timer, two to four UART/LIN channels, three to ten I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) channels - all configurable via dedicated SFRs and supported by DMA (4-channel controller).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GLAFB#X0 | Same package and memory (128 KB flash/8 KB data flash/12 KB RAM), but rated for −40°C to +85°C (D-grade) instead of +105°C (G-grade). | Not suitable for extended-temperature industrial enclosures or under-hood automotive auxiliary systems. | Select when ambient operating temperature remains ≤ +85°C and cost optimization is prioritized over thermal margin. |
| R5F101GLDFB#X0 | Identical pinout and package, but lacks on-chip data flash (0 KB); retains same code flash, RAM, peripherals, and G-grade temperature range. | Requires external nonvolatile memory for parameter storage or logging, increasing BOM count and PCB area. | Choose only if application does not require embedded data logging or field-updatable configuration storage. |
Compared with R5F100GLDFB#X0, R5F100GLAFB#X0 trades extended temperature capability for lower cost, while R5F101GLDFB#X0 removes data flash to reduce silicon area - both retain identical peripheral sets and instruction compatibility but constrain design flexibility in thermal or data persistence requirements.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GLDFB#X0?
The R5F100GLDFB#X0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This frequency is achievable using the high-accuracy on-chip oscillator (±1.0% over −20°C to +85°C), eliminating the need for an external crystal in many applications. The RL78 core's 3-stage pipeline ensures consistent instruction timing, supporting real-time control tasks such as motor commutation and sensor sampling at deterministic intervals.
Does the R5F100GLDFB#X0 support in-system programming and secure firmware updates?
Yes, the R5F100GLDFB#X0 supports full in-system programming via its on-chip debug interface and includes boot swap functionality for safe firmware updates. The flash shield window feature prevents unauthorized access to protected memory regions, and block erase prohibition enhances security against malicious reprogramming. These capabilities are implemented in hardware and do not require external programming hardware beyond standard SWD/JTAG tools.
How many analog input channels does the R5F100GLDFB#X0 provide, and what ADC resolution is supported?
The R5F100GLDFB#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor - both accessible via dedicated ANI pins. The ADC supports simultaneous sampling configurations and programmable conversion triggers, making it suitable for multi-sensor monitoring in industrial control applications.
What low-power modes are available on the R5F100GLDFB#X0, and what is the lowest achievable current draw?
The R5F100GLDFB#X0 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.57 μA. This enables years of operation on coin-cell batteries for timekeeping or wake-on-event applications. Wake-up sources include external interrupts, RTC alarms, and LVD threshold crossings - all configurable without CPU intervention.
Is the R5F100GLDFB#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GLDFB#X0 is pin-compatible with all other RL78/G13 devices in the 48-pin LFQFP (FB) package, including R5F100GLAFB#X0 and R5F101GLDFB#X0. Pin functions, power domains, and peripheral mappings are identical across this package group. However, differences in memory configuration (e.g., presence/absence of data flash) and temperature grade must be verified in software initialization and system qualification.
