Product details
Overview
R5F140FLGFP#30 from Renesas is a 64-pin LFQFP, industrial-grade RL78/G13A 16-bit microcontroller with 512 KB code flash, 8 KB data flash, and 32 KB RAM. It operates from 1.6–5.5 V, supports −40 to +105°C ambient, and delivers ultra-low power consumption (47 µA/MHz typ.) for battery-powered industrial control and appliance HMI applications.
For engineers reviewing the R5F140FLGFP#30 datasheet, R5F140FLGFP#30 pinout, R5F140FLGFP#30 application, or R5F140FLGFP#30 equivalent, this page provides verified technical context, package-accurate pin definitions, real-world use cases, and validated alternative options aligned to the RL78/G13A family specification R01DS0376EJ0110 Rev.1.10.
Technical Context
The R5F140FLGFP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs at 32 MHz HS oscillator or 30.5 µs at 32.768 kHz subsystem clock). It integrates dual serial array units supporting UART (LIN-capable), CSI, and I²C interfaces across up to 10 channels.
Its peripheral set includes an 8/10-bit 12-channel A/D converter with internal reference and temperature sensor, 12-bit interval timer, RTC with calendar and alarm, watchdog timer, DMA controller (4 channels), and multiplier/divider unit supporting 16×16→32-bit and 32÷32 operations - all operating under industrial temperature guarantee.

The R5F140FLGFP#30 supports a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy) and operates across a single 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device maintains full functionality across its industrial temperature range of −40 to +105°C.
Does the R5F140FLGFP#30 include hardware support for LIN bus communication?
Yes, the R5F140FLGFP#30 supports LIN bus communication through its UART peripherals - specifically UART0 and UART2, both explicitly documented as LIN-bus capable in the R01DS0376EJ0110 datasheet. This enables direct implementation of LIN slave nodes without external transceivers in many configurations.
How does the R5F140FLGFP#30 handle flash memory security and field updates?
The R5F140FLGFP#30 implements flash security via block erase prohibition, flash shield window configuration, and boot swap functionality. These features allow secure firmware updates in the field while preventing unauthorized readout or modification of protected code flash regions - essential for certified industrial deployments.
What are the key differences between the R5F140FLGFP#30 and R5F140FKGFP#30?
The R5F140FLGFP#30 features 512 KB code flash and 32 KB RAM, whereas the R5F140FKGFP#30 has 384 KB code flash and 24 KB RAM. Both share identical 64-pin LFQFP packaging, industrial temperature rating (−40 to +105°C), peripheral sets, and ultra-low power performance - making them drop-in compatible for footprint-constrained upgrades.
Can the R5F140FLGFP#30 operate reliably in high-noise factory environments?
Yes - the R5F140FLGFP#30 is engineered for industrial noise resilience: it supports separate EVDD0/EVSS0 power/ground domains for I/O ports, includes on-chip voltage detector (14-level LVD), POR circuit, and robust ESD tolerance. Its −40 to +105°C rating and 64-pin LFQFP package further enhance reliability in electrically noisy, thermally demanding settings.
