It integrates RTC, 10-bit ADC (20 channels), dual DAC, UART/SPI/I²C interfaces, and ultra-low-power modes (0.60 μA in STOP with RTC+LVD). Used in motor control, sensor hubs, and industrial HMI.
For engineers reviewing the R5F104LLGFB#30 datasheet, R5F104LLGFB#30 pinout, R5F104LLGFB#30 application, or R5F104LLGFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, -40°C to +105°C industrial temperature rating (G-grade), 512 KB code flash with self-programming support, and integrated event-link controller for deterministic peripheral triggering.
Technical Context
The R5F104LLGFB#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions. Its memory subsystem comprises 512 KB on-chip flash (1 KB blocks), 8 KB data flash with background operation (BGO), and 48 KB RAM - all accessible within a 1 MB address space.
Peripheral integration includes Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, calendar RTC with alarm/correction, watchdog timer, and Event Link Controller (ELC) enabling direct hardware linking of 19–26 event sources to peripherals without CPU intervention - critical for real-time deterministic response in industrial automation.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104LLGFB#30?
The R5F104LLGFB#30 operates at up to 32 MHz with its high-speed on-chip oscillator, delivering 44 DMIPS of processing performance. Its RL78 CPU core supports configurable instruction timing - minimum execution time is 0.03125 µs at 32 MHz, and extends to 30.5 µs at 32.768 kHz for ultra-low-power RTC operation. This dual-speed capability allows dynamic trade-offs between throughput and energy efficiency in battery-powered systems.
Does the R5F104LLGFB#30 support in-system programming and secure firmware updates?
Yes, the R5F104LLGFB#30 supports full in-system programming via its on-chip debug interface and includes flash shield window functionality to restrict write/erase access to designated memory regions. Self-programming with boot swapping enables safe dual-bank firmware updates, and data flash BGO allows parameter storage updates while application code continues executing - critical for field-deployed industrial equipment requiring zero-downtime maintenance.
What are the key power management features of the R5F104LLGFB#30 for battery-operated applications?
The R5F104LLGFB#30 delivers industry-leading low-power operation: 66 μA/MHz active current, 0.60 μA in STOP mode with RTC and LVD active, and configurable HALT/SNOOZE modes. Its internal LDO regulator (bypassed via REGC pin) and wide 1.6–5.5 V supply range allow direct connection to primary lithium cells or energy-harvesting sources. The SNOOZE mode enables peripheral-triggered wake-up with sub-μs latency - ideal for intermittent sensing applications.
How many analog-to-digital converter (ADC) channels does the R5F104LLGFB#30 provide, and what are their key specifications?
The R5F104LLGFB#30 integrates a 10-bit successive-approximation ADC with up to 20 input channels, operating across the full 1.6–5.5 V supply range. It includes an internal 1.45 V reference voltage and on-die temperature sensor, supporting simultaneous sampling with programmable conversion triggers (e.g., timer, ELC events). Conversion time is 1.15 μs per sample at 10-bit resolution, enabling real-time motor phase current monitoring or multi-sensor acquisition.
Is the R5F104LLGFB#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 MCUs in the 64-pin LFQFP-0.5mm package (e.g., R5F104LKGB#30, R5F104LLAFA, R5F104LLGFB#55) share identical pinouts and electrical characteristics. This enables hardware reuse across memory/configurations - firmware can be scaled to match flash/RAM resources, and PCBs designed for R5F104LLGFB#30 support drop-in substitution with lower-density variants without layout changes.
