Product details
Overview
R5F100LCGFA#30 from Renesas is a 64-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed (41 DMIPS), and ultra-low-power operation down to 0.57 μA in RTC+LVD mode. It integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC with calendar, and operates from 1.6–5.5 V across –40°C to +105°C for industrial control and sensor nodes.
For engineers reviewing the R5F100LCGFA#30 datasheet, R5F100LCGFA#30 pinout, R5F100LCGFA#30 application, or R5F100LCGFA#30 equivalent, key selection criteria include industrial temperature grade (G), integrated data flash with background operation, low-power STOP/HALT/SNOOZE modes, and peripheral mix supporting motor control, HMI, and battery-powered IoT edge devices.
Technical Context
The R5F100LCGFA#30 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features on-chip debug, self-programming with boot swap, and flash shield window security.
Its power management includes an on-chip POR circuit, 14-level LVD with interrupt/reset options, and DMA controller (4 channels) enabling efficient memory transfers in just 2 clocks between SFR and RAM. The high-accuracy ±1.0% on-chip oscillator eliminates external crystal requirements for many timing-critical applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGFA#30 | Same package and pinout; reduced memory (96 KB flash, 4 KB data flash, 8 KB RAM) | Suitable for cost-sensitive designs with lower firmware footprint and simpler data logging needs | Select when application fits within smaller memory and does not require extended RTC calendar or large BGO buffers |
| R5F101LCFA#30 | No data flash; identical core, peripherals, and package-but lacks background rewrite capability and flash security features | Applicable where firmware updates occur only during factory programming or where external EEPROM handles parameter storage | Choose only if data flash functionality is unnecessary and BOM cost reduction outweighs field-upgrade flexibility |
Compared with R5F100LCGFA#30, R5F100LGFA#30 trades memory capacity for lower unit cost while retaining industrial temperature rating and low-power modes, whereas R5F101LCFA#30 removes data flash entirely-eliminating BGO and flash shielding but simplifying qualification for safety-critical medical firmware that avoids runtime reprogramming.

FAQ
What is the operating temperature range for R5F100LCGFA#30?
The R5F100LCGFA#30 is rated for industrial operation from –40°C to +105°C (G-grade), validated across its full voltage range (1.6–5.5 V) and all specified peripheral functions. This makes it suitable for under-hood automotive modules, factory-floor controllers, and outdoor metering equipment where ambient extremes are expected.
Does R5F100LCGFA#30 include an integrated RTC with calendar function?
Yes, the R5F100LCGFA#30 includes a dedicated real-time clock peripheral supporting full calendar operation (year/month/day/hour/minute/second), alarm interrupts, and automatic clock correction. It operates independently in STOP mode using the 32.768 kHz subsystem clock, maintaining timekeeping at 0.57 μA total current draw.
Can R5F100LCGFA#30 execute code while rewriting data flash memory?
Yes, the R5F100LCGFA#30 supports background operation (BGO) for data flash. During data flash erase/write sequences, the CPU can continue executing instructions from code flash-enabling uninterrupted real-time tasks such as motor control loops or sensor sampling while logging data or applying firmware patches.
What packaging and lead pitch does R5F100LCGFA#30 use?
R5F100LCGFA#30 uses a 64-pin LQFP package with 12 mm × 12 mm body size and 0.65 mm lead pitch (PLQP0064JA-A). It is RoHS-compliant, halogen-free, and rated at moisture sensitivity level 3-requiring bake conditioning if exposed beyond floor life before reflow soldering.
Is there hardware support for LIN bus communication in R5F100LCGFA#30?
Yes, the R5F100LCGFA#30's UART peripherals support LIN 2.2 protocol natively-including automatic sync-field detection, checksum calculation (classic/enhanced), and break signal generation-without external transceivers or firmware overhead. This is confirmed in the RL78/G13 datasheet Section 1.1 Features and UART functional description.
