Product details
Overview
R5F100LGAFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and true low-power operation (66 μA/MHz active, 0.57 μA in RTC+LVD mode). It integrates 16-bit timers, 10-bit ADC (26 channels), UART, I²C, CSI, RTC, and DMA for embedded control in battery-powered and energy-sensitive systems.
For engineers reviewing the R5F100LGAFB#30 datasheet, R5F100LGAFB#30 pinout, R5F100LGAFB#30 application, or R5F100LGAFB#30 equivalent, key selection considerations include its 64-pin LFQFP-0.5mm package, -40°C to +105°C industrial temperature grade (G suffix), integrated data flash with 1M rewrite cycles, real-time clock with calendar/alarm, and support for SNOOZE mode for ultra-low-power sensor wake-up.
Technical Context
The R5F100LGAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling variable instruction execution time from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB on-chip code flash (1 KB block size), 8 KB data flash supporting background operation (BGO), and 12 KB RAM - all accessible under single 1.6–5.5 V supply.
Peripheral integration targets deterministic real-time control: dual 16-bit timer arrays (up to 16 channels total), 10-bit A/D converter with internal reference and temperature sensor, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, and 2–8-channel CSI (SPI-compatible serial interface), all configurable via dedicated SFRs and supported by DMA channels for zero-CPU-overhead data movement.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LGAFB#30?
The R5F100LGAFB#30 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over -40°C to +85°C), delivering 41 DMIPS of processing performance. This frequency is achievable with the internal oscillator alone - no external crystal required for basic timing-critical applications like motor control or sensor sampling.
Does the R5F100LGAFB#30 support in-system programming and secure firmware updates?
Yes, the R5F100LGAFB#30 supports full in-system programming via its on-chip debug interface and includes flash shield window functionality to prevent unauthorized read-out of code flash contents. It also features boot swap capability, enabling safe dual-bank firmware updates without risk of bricking the device during field upgrades.
How does the data flash in the R5F100LGAFB#30 differ from standard code flash in terms of usage and endurance?
The R5F100LGAFB#30 includes 8 KB of dedicated data flash rated for 1,000,000 write/erase cycles at 1.8–5.5 V, versus 100,000 cycles typical for code flash. Data flash supports background operation (BGO), allowing program execution from code flash while rewriting data - essential for reliable runtime parameter storage and firmware logging.
What are the key low-power modes supported by the R5F100LGAFB#30, and what functions remain active in each?
The R5F100LGAFB#30 offers HALT, STOP, and SNOOZE modes. In STOP mode, only RTC and LVD remain active at 0.57 μA. SNOOZE mode keeps selected peripherals (e.g., UART, ADC, CSI) operational while CPU sleeps - enabling wake-on-receive or wake-on-conversion with minimal latency and current draw.
Is the R5F100LGAFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 64-pin LFQFP-0.5mm package (e.g., R5F100LGAFB#30, R5F101LGAFB#30, R5F100LLAFB#30) share identical pinouts and electrical characteristics. This allows hardware reuse across memory/configurations - only flash size, data flash presence, and RAM capacity differ between variants.
