Product details
Overview
R5F140GKGFB#30 from Renesas is a 48-pin LFQFP, industrial-grade RL78/G13A 16-bit microcontroller with 384 KB code flash, 8 KB data flash, and 24 KB RAM. It operates from 1.6–5.5 V, delivers ultra-low power consumption (47 µA/MHz typ.), and supports ambient temperatures up to +105°C. It integrates UART/LIN, I²C, CSI, 16-bit timers, RTC, and 10-channel 8/10-bit ADC - deployed in motor control subsystems of HVAC controllers.
For engineers reviewing the R5F140GKGFB#30 datasheet, R5F140GKGFB#30 pinout, R5F140GKGFB#30 application, or R5F140GKGFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, G-grade temperature rating, 384 KB flash configuration, low-power STOP/HALT/SNOOZE modes, and integrated LIN-capable UART for automotive body electronics interoperability.

FAQ
What is the maximum operating frequency and voltage range supported by the R5F140GKGFB#30?
The R5F140GKGFB#30 supports a maximum high-speed on-chip oscillator frequency of 32 MHz and operates across a single supply voltage range of 1.6 V to 5.5 V. At 32 MHz, minimum instruction execution time is 0.03125 µs; the device maintains full functionality across its rated industrial temperature range (-40°C to +105°C) within this voltage window.
Does the R5F140GKGFB#30 support LIN bus communication natively?
Yes, the R5F140GKGFB#30 includes UART0 with built-in LIN 2.2 protocol support, including automatic sync-break detection, checksum generation, and wakeup functionality. No external LIN transceiver is required for basic slave-node operation, reducing BOM cost and board space in automotive body electronics designs using the R5F140GKGFB#30.
How many analog input channels does the R5F140GKGFB#30 provide, and what is their resolution?
The R5F140GKGFB#30 integrates a 10-channel 8/10-bit successive-approximation ADC with selectable resolution. Inputs include ANI0–ANI7 (on Port 2), plus ANI18 and ANI19 (on Ports 14 and 12), all referenced to dedicated AVREFP/AVREFM pins. The ADC operates across the full 1.6–5.5 V supply range and supports internal temperature sensing and 1.45 V reference voltage.
What low-power modes are available on the R5F140GKGFB#30, and what is the typical current draw in each?
The R5F140GKGFB#30 offers HALT (0.52 µA typ.), STOP (0.23 µA typ.), and SNOOZE modes. In STOP mode, RAM and RTC remain powered while CPU and most peripherals halt; wake-up occurs via external interrupt or RTC alarm. HALT retains more peripheral clocks and offers faster wake-up latency. All modes are fully supported across the -40°C to +105°C industrial temperature range.
Is the R5F140GKGFB#30 pin-compatible with other RL78/G13A variants like R5F140GLGFB#30?
Yes, the R5F140GKGFB#30 and R5F140GLGFB#30 share identical 48-pin LFQFP-0.5mm packaging, pin assignment, and electrical characteristics. They differ only in memory configuration (384 KB/24 KB vs. 512 KB/32 KB flash/RAM) and are software-binary compatible - enabling scalable design reuse across product tiers without PCB redesign when using the R5F140GKGFB#30 or R5F140GLGFB#30.
