Product details
Overview
R5F100JLAFA#30 from Renesas is a 52-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 256 KB flash, 8 KB data flash, 20 KB RAM, 16-bit RL78 CPU core, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces requiring mixed-signal integration and long-term firmware reliability.
For engineers reviewing the R5F100JLAFA#30 datasheet, R5F100JLAFA#30 pinout, R5F100JLAFA#30 application, or R5F100JLAFA#30 equivalent, key selection criteria include its 52-pin LQFP package with 26-channel 10-bit ADC, dual UART/LIN support, 8-channel 16-bit timer, real-time clock with calendar, and on-chip debug capability for field-deployable firmware updates.
Technical Context
The R5F100JLAFA#30 implements the RL78 CISC core with 3-stage pipeline and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz), enabling dynamic power/performance scaling across sensor sampling, communication, and sleep states. Its memory subsystem includes 256 KB code flash with 1 KB block erase, 8 KB background-operable data flash (1M rewrite cycles), and 20 KB SRAM - all supporting self-programming with boot swap and flash shield window functions.
Peripherals are tightly integrated for embedded control: dual UARTs with LIN bus compliance, up to 10 I²C channels, 8 CSI/SPI channels, 16-bit timers with PWM output, 12-bit interval timer, RTC with alarm/calendar, watchdog timer, DMA controller (4 channels), and 16×16/32÷32 multiplier-accumulator - all operating across 1.6–5.5 V supply and -40°C to +85°C ambient.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100JLAFA#30?
The R5F100JLAFA#30 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C). At this frequency, active current consumption is 66 μA per MHz - resulting in approximately 2.1 mA total at 32 MHz with typical peripheral enablement. In STOP mode with only RTC and LVD active, it draws just 0.57 μA, enabling decade-long battery operation in intermittent-sensing applications.
Does the R5F100JLAFA#30 support in-system programming and secure firmware updates?
Yes, the R5F100JLAFA#30 supports full in-system programming via on-chip debug interface and includes multiple security features: flash block erase/write prohibition, boot swap functionality for fail-safe updates, and flash shield window protection to prevent unauthorized access to critical firmware sections - all essential for certified industrial and utility-grade deployments.
How many serial communication interfaces does the R5F100JLAFA#30 provide, and which protocols are supported?
The R5F100JLAFA#30 integrates up to 4 UART channels (2 with LIN bus support), 3–10 I²C channels, and 2–8 CSI/SPI channels - all independently clocked and configurable. This enables concurrent use of UART for host debugging, LIN for automotive subsystems, I²C for sensor hubs, and SPI for display or memory expansion without resource contention.
What ADC capabilities does the R5F100JLAFA#30 offer for sensor interfacing?
The R5F100JLAFA#30 features a 10-bit successive-approximation ADC with 26 input channels, selectable internal 1.45 V reference voltage, and integrated temperature sensor. It supports simultaneous sampling on multiple channels, hardware-triggered conversions synchronized to timers, and programmable sample-and-hold timing - making it suitable for precision analog front-end applications like environmental monitoring and motor current sensing.
Is the R5F100JLAFA#30 pin-compatible with other RL78/G13 variants in the 52-pin LQFP package?
Yes, all RL78/G13 devices in the 52-pin LQFP-0.65mm package (e.g., R5F100JCAFA#30, R5F100JGAFA#30, R5F100JLAFA#30) share identical pinouts and electrical characteristics. This allows direct substitution within the same memory/peripheral configuration tier, simplifying design reuse and enabling scalable firmware deployment across product families.
