Product details
Overview
R5F104LCGFP#50 from Renesas is a 64-pin LQFP-0.65mm-pitch, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 512 KB flash, 8 KB data flash, 48 KB RAM, and integrated RTC, 10-bit ADC (20 channels), UART/LIN, I²C, SPI, and ultra-low-power operation (0.60 μA in STOP mode). It targets battery-powered industrial control and sensor interface applications requiring high code density and mixed-signal integration.
For engineers reviewing the R5F104LCGFP#50 datasheet, R5F104LCGFP#50 pinout, R5F104LCGFP#50 application, or R5F104LCGFP#50 equivalent, key selection criteria include its 64-pin LQFP package, G-grade temperature rating, 512 KB/8 KB/48 KB memory configuration, hardware event linking (ELC), and background data flash rewriting capability - all critical for deterministic real-time firmware updates and long-life embedded deployments.
Technical Context
The R5F104LCGFP#50 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 integrates 512 KB code flash (1 KB blocks), 8 KB data flash with background operation (BGO), and 48 KB RAM - enabling secure self-programming with boot swapping and flash shield window protection.
Peripherals include 20-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, dual UART/LIN interfaces, up to 10 I²C channels, 8–12 × 16-bit timers (including calendar RTC and watchdog), and the Event Link Controller (ELC) that routes 19–26 event signals directly to peripherals without CPU intervention - reducing latency and power in event-driven systems.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LLGFP#50 | Same 64-pin LQFP-0.65mm package, identical G-grade temp range, but 384 KB flash / 32 KB RAM | Lower memory capacity suits cost-sensitive industrial controls where firmware size < 384 KB | Select when full 512 KB flash is unnecessary and BOM cost optimization is prioritized |
| R5F104LGGBG#50 | 64-pin LQFP-0.5mm pitch, same 512 KB/8 KB/48 KB memory, G-grade, but LFQFP package | Smaller footprint (10 × 10 mm vs. 12 × 12 mm) and finer pitch suit space-constrained PCBs | Choose for higher-density layouts where 0.5 mm pitch assembly is available and thermal margin permits |

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104LCGFP#50?
The R5F104LCGFP#50 operates at up to 32 MHz with a measured performance of 44 DMIPS. This value is derived from the RL78 CPU core's 3-stage pipeline architecture and confirmed in the official RL78/G14 datasheet (R01DS0053EJ0370). The R5F104LCGFP#50 achieves this performance while maintaining ultra-low power consumption - 66 μA per MHz - making it suitable for high-efficiency real-time control tasks.
Does the R5F104LCGFP#50 support background data flash rewriting while executing code from main flash memory?
Yes, the R5F104LCGFP#50 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors - essential for seamless firmware parameter updates and logging without interrupting real-time operation. The R5F104LCGFP#50 implements this using dedicated flash control hardware and interrupt flags documented in Section 22 of the datasheet.
What are the key differences between the R5F104LCGFP#50 and R5F104LLGFP#50?
The R5F104LCGFP#50 and R5F104LLGFP#50 share identical 64-pin LQFP-0.65mm packaging, G-grade temperature range (−40°C to +105°C), and peripheral sets. Their primary difference lies in memory: R5F104LCGFP#50 has 512 KB code flash / 48 KB RAM, whereas R5F104LLGFP#50 offers 384 KB flash / 32 KB RAM. Both use the same 8 KB data flash and support identical low-power modes and debug features. The R5F104LCGFP#50 is selected when full firmware headroom or large RTOS workloads demand maximum memory.
Which serial communication interfaces are available on the R5F104LCGFP#50, and how many instances does each support?
The R5F104LCGFP#50 provides three UART/LIN interfaces, up to ten I²C/simplified I²C channels, and three to eight CSI (SPI-compatible) channels. Specifically, it includes UART0, UART1, and UART2 - all supporting LIN bus protocol - plus I²C0 through I²C9 (configurable per pin mapping) and CSI0 through CSI7. These interfaces are multiplexed across GPIO pins and managed via the Peripheral I/O Redirection Registers (PIOR0/1), allowing flexible routing without hardware redesign. The R5F104LCGFP#50 leverages these to support multi-protocol industrial connectivity.
How does the Event Link Controller (ELC) enhance real-time responsiveness in the R5F104LCGFP#50?
The Event Link Controller (ELC) in the R5F104LCGFP#50 enables direct hardware-level linking of up to 26 peripheral events - such as ADC conversion completion, timer overflow, or external interrupt assertion - to target functions like timer start/stop, DMA trigger, or DAC update, without CPU involvement. This eliminates ISR latency and software overhead, ensuring sub-microsecond response times for time-critical operations. The R5F104LCGFP#50 uses ELC to synchronize sensor sampling, motor control PWM, and communication handshaking deterministically - a key advantage in closed-loop industrial systems.
