Product details
Overview
R5F140LLAFB#30 from Renesas is a 64-pin LFQFP, 512 KB code flash, 32 KB RAM, 8 KB data flash RL78/G13A 16-bit microcontroller operating at 1.6–5.5 V with ultra-low power consumption (47 µA/MHz typ.) and industrial-grade temperature support up to +105°C. It integrates 12-channel 8/10-bit ADC, 8× 16-bit timers, RTC, UART/LIN, I²C, CSI, DMA, and on-chip debug for embedded control in appliance motor drives and industrial HMI.
For engineers reviewing the R5F140LLAFB#30 datasheet, R5F140LLAFB#30 pinout, R5F140LLAFB#30 application, or R5F140LLAFB#30 equivalent, this page delivers verified electrical specs, package mapping, functional role in real systems, and validated alternative selection guidance for production design-in.
Technical Context
The R5F140LLAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports dual power domains (VDD/EVDD0) and separate analog/digital grounds (VSS/EVSS0) for noise-sensitive mixed-signal operation.
Its peripheral set includes UART0–UART2 with LIN-bus support, up to 10 I²C/Simplified I²C channels, 4–8 CSI channels, 12-bit interval timer, BCD correction circuit, and background data flash rewriting (BGO) enabling concurrent execution and non-volatile storage updates without halting program flow.

FAQ
What is the maximum operating frequency of the R5F140LLAFB#30?
The R5F140LLAFB#30 supports up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy over -40°C to +85°C), or up to 20 MHz when using an external crystal (X1/X2) in HS mode. The actual achievable frequency depends on VDD voltage level and selected clock source configuration per the RL78/G13A User's Manual Section 5.2.
Does the R5F140LLAFB#30 support LIN bus communication?
Yes, the R5F140LLAFB#30 supports LIN bus communication through UART2, which includes LIN 2.2-compliant frame formatting, checksum generation, and synchronization break detection. This capability is confirmed in the RL78/G13A datasheet Section 1.1 Features and Section 13.3.2 UART2 Functional Description.
How many analog input channels does the R5F140LLAFB#30 have?
The R5F140LLAFB#30 provides 12 analog input channels (ANI0–ANI7, ANI16–ANI19) as specified for 64-pin RL78/G13A devices in Table 1-1 and Section 1.6 Outline of Functions. This includes dedicated AVREFP/AVREFM pins and supports internal temperature sensor and 1.45 V reference voltage selection.
What is the purpose of the EVDD0 and EVSS0 pins on the R5F140LLAFB#30?
The EVDD0 and EVSS0 pins on the R5F140LLAFB#30 supply and ground the I/O port circuitry separately from the core logic (VDD/VSS). This separation minimizes digital switching noise coupling into analog peripherals and ADC measurements, as explicitly required in datasheet Cautions for 64-pin products (Section 1.3.3).
Can the R5F140LLAFB#30 perform flash self-programming while executing code from main memory?
Yes, the R5F140LLAFB#30 supports flash self-programming with boot swap functionality and background operation (BGO) for data flash. Code flash updates require HALT mode, but data flash rewriting can occur concurrently with program execution from code flash, enabling seamless firmware parameter updates without interrupting real-time tasks.
