It operates from 1.6–5.5 V, delivers ultra-low power consumption (47 µA/MHz typ.), supports −40 to +105°C ambient, and integrates UART/LIN, I²C, CSI, RTC, 16-bit timers, and 10-channel 8/10-bit ADC - deployed in motor control and smart appliance subsystems.
For engineers reviewing the R5F140GKAFB#30 datasheet, R5F140GKAFB#30 pinout, R5F140GKAFB#30 application, or R5F140GKAFB#30 equivalent, this page provides verified package mapping (LFQFP-48), confirmed industrial temperature rating (−40 to +105°C), validated low-power operating modes (HALT/STOP/SNOOZE), and real-world interface compatibility for LIN-bus communication and key-return matrix interfaces.
Technical Context
The R5F140GKAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution time of 0.03125 µs at 32 MHz (high-speed on-chip oscillator) or 30.5 µs at 32.768 kHz (subsystem clock). Its memory map spans 1 MB address space with dual-bank register organization (8-bit × 8 registers × 4 banks).
It features integrated power management including on-chip POR and 14-level LVD, DMA controller (2 channels), multiplier/divider/MAC unit (16×16→32, 32÷32→32), and peripheral I/O redirection via PIOR register - enabling flexible pin assignment for UART0/1/2, I²C0/1/2, CSI0/1/2, and timer I/O without hardware redesign.

FAQ
What is the maximum operating frequency and clock source flexibility for the R5F140GKAFB#30?
The R5F140GKAFB#30 supports up to 32 MHz via its high-speed on-chip oscillator (±1.0% accuracy), or up to 20 MHz using an external crystal on X1/X2. It also accepts external clocks on EXCLK/EXCLKS pins and operates down to 32.768 kHz for ultra-low-power RTC and SNOOZE modes - all configurable without external components. The R5F140GKAFB#30's clock system enables dynamic switching between performance and power-saving states.
Does the R5F140GKAFB#30 support LIN bus communication, and which peripheral handles it?
Yes, the R5F140GKAFB#30 supports LIN 2.2 protocol through UART2 (mapped to P13/TxD2 and P14/RxD2), with hardware-assisted sync-break detection, checksum calculation, and identifier filtering. This eliminates software overhead for LIN frame processing and ensures deterministic timing - critical for automotive body electronics and industrial sub-networks. The R5F140GKAFB#30 integrates LIN functionality directly into its UART peripheral without requiring external transceivers for basic compliance testing.
How does the R5F140GKAFB#30 manage power during deep sleep, and what wake-up sources are available?
The R5F140GKAFB#30 offers three ultra-low-power modes: HALT (0.52 µA), STOP (0.23 µA), and SNOOZE (1.2 µA with selected peripherals active). Wake-up sources include external interrupts (INTP0–INTP11), key return scan (KR0–KR5), RTC alarm, 12-bit interval timer, and serial interface activity. All wake-up events trigger full register restore within 4 µs. The R5F140GKAFB#30's power architecture enables battery-powered operation for years in sensor nodes and remote controls.
Can the R5F140GKAFB#30 perform simultaneous code execution and data flash rewriting?
Yes, the R5F140GKAFB#30 supports Background Operation (BGO) for its 8 KB data flash memory, allowing instruction fetch and execution from code flash while rewriting data flash sectors. This enables seamless firmware parameter updates, calibration storage, or event logging without halting real-time tasks. The R5F140GKAFB#30's flash library reserves RAM at address F7F00H for self-programming operations, ensuring deterministic timing and safe erase/write sequences.
What is the ADC configuration and reference voltage capability of the R5F140GKAFB#30?
The R5F140GKAFB#30 integrates a 10-channel 8/10-bit successive-approximation ADC with selectable resolution, internal 1.45 V reference (available only in HS mode), and dedicated AVREFP/AVREFM pins for external reference. It supports single- or continuous-conversion modes, scan sequencing, and hardware-triggered sampling synchronized to timers. The R5F140GKAFB#30's ADC meets precision requirements for motor current sensing, battery voltage monitoring, and environmental sensor interfacing across its full −40 to +105°C range.
