Renesas R5F100LLGFB#30

Overview

R5F100LLGFB#30 from Renesas is a 64-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 512 KB flash, 8 KB data flash, 32 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 RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.

For engineers reviewing the R5F100LLGFB#30 datasheet, R5F100LLGFB#30 pinout, R5F100LLGFB#30 application, or R5F100LLGFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm pitch package, G-grade temperature range (−40°C to +105°C), integrated data flash with 1M rewrite cycles, BGO-capable background rewriting, and hardware multiplier/divider for deterministic control math.

Technical Context

The R5F100LLGFB#30 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 ultra-low-speed mode). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.

Power management includes HALT, STOP, and SNOOZE modes; on-chip LVD offers 14 selectable voltage detection levels with interrupt/reset options; DMA controller provides 4 channels with 2-clock transfers between SFR and RAM; and the real-time clock features calendar support (99-year range), alarm, and clock correction.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100LLGFB#30?

The R5F100LLGFB#30 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and −40°C to +105°C. The RL78 core's 3-stage pipeline and optimized instruction set enable deterministic real-time response for control loops and communication stacks in the R5F100LLGFB#30.

Does the R5F100LLGFB#30 support background data flash rewriting while executing application code?

Yes, the R5F100LLGFB#30 supports background operation (BGO) for data flash. While the CPU executes instructions from program memory, the data flash can be rewritten - enabling seamless firmware updates, parameter logging, or calibration storage without halting real-time tasks. This capability is intrinsic to the R5F100LLGFB#30's flash controller and requires no external hardware.

What are the low-power consumption specifications for the R5F100LLGFB#30 in STOP and HALT modes?

In STOP mode with only RTC and LVD active, the R5F100LLGFB#30 consumes 0.57 μA (typical). In HALT mode, it draws 66 μA per MHz of active core frequency. These values are measured under specified conditions (VDD = 1.8–5.5 V, TA = −40°C to +105°C) and reflect the R5F100LLGFB#30's true low-power platform design for battery longevity in always-on sensor and metering applications.

How many analog input channels and what resolution does the ADC in the R5F100LLGFB#30 provide?

The R5F100LLGFB#30 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), configurable across multiple ports. It supports internal reference voltage (1.45 V) and an integrated temperature sensor. This ADC capability is fully documented in the R5F100LLGFB#30 datasheet and enables direct sensing of voltage, current, temperature, and environmental parameters without external signal conditioning.

Is the R5F100LLGFB#30 pin-compatible with other RL78/G13 variants in the same 64-pin LFQFP package?

Yes, all RL78/G13 devices in the 64-pin LFQFP package - including R5F100LLGFB#30, R5F100LLAFB#30, and R5F101LLGFB#30 - share identical pinouts and mechanical footprint. Signal mapping, power/ground pin locations, and debug interface pins are consistent across this package group, allowing PCB reuse when migrating between variants with differing flash, RAM, or data flash configurations - a verified feature of the R5F100LLGFB#30 family.
