Product details
Overview
R5F10RJCGFA#10 from Renesas is a 52-pin LQFP-packaged 16-bit RL78/L12 microcontroller with 32 KB flash, 2 KB data flash, and 1.5 KB RAM, operating from 1.6 V to 5.5 V. It integrates an LCD controller/driver (up to 35 seg × 8 com), 10-channel 10-bit ADC, RTC with calendar, and ultra-low-power operation (0.64 µA in Halt mode with RTC + LVD), targeting battery-powered LCD display systems such as smart meters and portable medical devices.
For engineers reviewing the R5F10RJCGFA#10 datasheet, R5F10RJCGFA#10 pinout, R5F10RJCGFA#10 application, or R5F10RJCGFA#10 equivalent, this device delivers verified low-power performance, on-chip LCD drive capability, real-time clock functionality, and industrial-grade temperature range (−40°C to +105°C) for embedded metering and human-interface applications.
Technical Context
The R5F10RJCGFA#10 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 cycles. It supports multiple clock sources: high-speed on-chip oscillator (24 MHz ±1%), external crystal (X1/X2), and subsystem clock (XT1/XT2 at 32.768 kHz).
Its integrated peripherals include two CSI interfaces (SPI-compatible), one I²C, one UART, eight 16-bit timer channels, DMA controller (2 channels), and safety features compliant with IEC/UL 60730 - including RAM parity check, flash CRC, and illegal memory access detection.

What is the maximum operating frequency and power consumption of the R5F10RJCGFA#10?
The R5F10RJCGFA#10 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS. Its active power consumption is 62.5 µA per MHz, and it achieves 0.64 µA in Halt mode with RTC and LVD enabled - making it ideal for battery-backed LCD applications where runtime and wake-up latency are critical.
Does the R5F10RJCGFA#10 support external crystal oscillators?
Yes, the R5F10RJCGFA#10 supports external crystal oscillators on X1/X2 pins for main system clock (1–20 MHz) and XT1/XT2 pins for subsystem clock (32.768 kHz). This enables precise RTC operation and synchronization with external timing references while retaining the flexibility of the internal 24 MHz oscillator for general processing.
How many LCD segments and commons can the R5F10RJCGFA#10 drive?
The R5F10RJCGFA#10 supports up to 35 segment × 8 common or 39 segment × 4 common LCD configurations. It provides dedicated VL1–VL4 power rails and COM0–COM7 outputs, along with configurable drive methods (capacitor split, internal boost, resistance division) - enabling direct interface to a wide range of passive segment LCDs without external bias ICs.
What safety certifications or features does the R5F10RJCGFA#10 include?
The R5F10RJCGFA#10 includes hardware-level safety features aligned with IEC/UL 60730 Class B requirements: flash memory CRC calculation, RAM parity error checking, SFR write protection, illegal memory access detection, clock frequency monitoring, and ADC self-test - enabling certified functional safety compliance without external supervision circuits.
Is the R5F10RJCGFA#10 pin-compatible with other RL78/L12 variants?
The R5F10RJCGFA#10 uses a 52-pin LQFP package (0.65 mm pitch) and shares identical pinout with other R5F10RJx-series devices (e.g., R5F10RJAGFA#10, R5F10RJ8GFA#10). However, it is not pin-compatible with 32-, 44-, 48-, or 64-pin RL78/L12 variants due to differing pin counts and layout constraints.
