Product details
Overview
R5F104LGAXXXFB#30 from Renesas is a 64-pin LFQFP (0.5 mm pitch), 512 KB flash, 8 KB data flash, 12 KB RAM RL78/G14 16-bit MCU operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in industrial motor control and sensor interface modules.
For engineers reviewing the R5F104LGAXXXFB#30 datasheet, R5F104LGAXXXFB#30 pinout, R5F104LGAXXXFB#30 application, or R5F104LGAXXXFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, -40°C to +105°C industrial temperature grade (G), integrated RTC with calendar/alarm, dual 10-bit ADC (20-channel), and hardware event link controller for deterministic peripheral triggering.
Technical Context
The R5F104LGAXXXFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions with 1 MB address space. It integrates a Data Transfer Controller (DTC) with chain transfer and an Event Link Controller (ELC) enabling direct peripheral-to-peripheral signal routing without CPU intervention.
Its clock system features a high-accuracy ±1.0% on-chip oscillator (selectable 1–64 MHz), independent subsystem clock for RTC/LVD operation, and support for external crystals (X1/X2) or resonators (XT1/XT2). Power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD with interrupt/reset capability.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104LGAXXXFB#30?
The R5F104LGAXXXFB#30 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 44 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 µs at this speed. The device also supports ultra-low-speed operation down to 32.768 kHz (30.5 µs instruction time) for RTC and LVD functions in STOP mode, maintaining full functionality at 0.60 μA.
Does the R5F104LGAXXXFB#30 support in-system programming and secure firmware updates?
Yes, the R5F104LGAXXXFB#30 supports full in-system programming via its on-chip debug function and self-programming capability with boot swapping. It includes flash shield window protection and block erase prohibition for security. Data flash supports background operation (BGO), allowing CPU execution from program memory during rewrites-enabling secure, seamless firmware updates without interrupting real-time operation.
What analog peripherals are integrated into the R5F104LGAXXXFB#30 and how are they configured?
The R5F104LGAXXXFB#30 integrates a 10-bit ADC with up to 20 input channels, internal 1.45 V reference voltage, and on-chip temperature sensor; two 8-bit DACs with 0–VDD output range and real-time update capability; and up to two comparators with selectable internal/external reference and window mode. All analog resources are accessible via dedicated pins and configurable through register settings without external components.
How does the Event Link Controller (ELC) enhance real-time responsiveness in the R5F104LGAXXXFB#30?
The ELC in the R5F104LGAXXXFB#30 enables direct hardware-level linking of 19–26 peripheral event sources (e.g., timer overflow, ADC end-of-conversion, UART receive) to target functions (e.g., start ADC conversion, trigger PWM reload, increment counter) without CPU involvement. This eliminates interrupt latency and software overhead, achieving deterministic sub-cycle response times critical for motor control and high-speed data acquisition.
What package and pin count does the R5F104LGAXXXFB#30 use, and what are its key mechanical identifiers?
The R5F104LGAXXXFB#30 uses a 64-pin LFQFP package with 10 × 10 mm body size and 0.5 mm pin pitch (FB suffix). It has no exposed thermal pad.
