Product details
Overview
R5F104LCGFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade RL78/G14 16-bit MCU with 512 KB flash, 48 KB RAM, and 8 KB data flash. It operates from 1.6–5.5 V, achieves 44 DMIPS at 32 MHz, and delivers ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), targeting battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F104LCGFB#30 datasheet, R5F104LCGFB#30 pinout, R5F104LCGFB#30 application, or R5F104LCGFB#30 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options for design-in and supply continuity planning.
Technical Context
The R5F104LCGFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed on-chip oscillator.
Peripheral integration includes up to 20-channel 8/10-bit ADC with internal 1.45 V reference and temperature sensor, two 8-bit DAC channels, up to 12× 16-bit timers (TAU, RJ, RD, RG), 4–10× I²C interfaces, 3–4× UART/LIN channels, and 3–8× CSI (SPI-compatible) channels - all managed via Event Link Controller (ELC) and Data Transfer Controller (DTC) for autonomous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
Package: 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), RoHS-compliant, moisture-sensitive level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P121 / X1 | Crystal input | Connects to 32.768 kHz tuning-fork crystal for RTC accuracy; requires external load capacitors. |
| P122 / X2 / EXCLK | Crystal output / external clock input | Drives crystal; alternatively accepts external 1–20 MHz clock source for system synchronization. |
