Product details
Overview
R5F100JHGFA#V0 from Renesas is a 52-pin LQFP-0.65mm 8-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for battery-powered industrial control and sensor interface applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100JHGFA#V0 datasheet, R5F100JHGFA#V0 pinout, R5F100JHGFA#V0 application, or R5F100JHGFA#V0 equivalent, key selection criteria include ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated LIN-capable UART, hardware multiplier/divider, and 52-pin LQFP package compatibility with industrial temperature range (–40°C to +105°C).
Technical Context
The R5F100JHGFA#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and DMA controller with up to 4 channels.
It features dual-clock domains: high-accuracy on-chip oscillator (±1.0% over –20°C to +85°C) configurable from 1 MHz to 32 MHz, and dedicated low-speed oscillator for watchdog and RTC. Serial interfaces include up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - all independently configurable per peripheral instance.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F100JHGFA#V0?
The R5F100JHGFA#V0 operates up to 32 MHz using its high-accuracy on-chip oscillator. At this frequency, typical active current is 66 μA per MHz, resulting in ~2.1 mA total at 32 MHz under standard conditions. The device also supports lower-frequency modes (e.g., 32.768 kHz for RTC) consuming only 0.57 μA in STOP mode with RTC and LVD active - verified in the R01DS0131EJ0380 datasheet Section 1.1.
Does the R5F100JHGFA#V0 support LIN bus communication, and which UART channel implements it?
Yes, the R5F100JHGFA#V0 supports LIN 2.2 protocol via its UART peripherals. Specifically, UART0 through UART3 each support LIN break detection, sync field generation, and checksum handling in hardware. UART0 is commonly used for LIN due to its default mapping on P11/P12 pins, but any UART channel can be configured as LIN master or slave - confirmed in Section 1.1 "Serial interface" of the R01DS0131EJ0380 datasheet.
What is the data flash endurance and voltage range for rewriting the R5F100JHGFA#V0?
The R5F100JHGFA#V0 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with guaranteed operation across VDD = 1.8 V to 5.5 V. Rewrites occur in background (BGO) without halting CPU execution, and the flash library reserves RAM starting at address FAF00H - details are specified in Section 1.1 "Data Flash Memory" and Table on Page 3 of the R01DS0131EJ0380 datasheet.
How many ADC channels does the R5F100JHGFA#V0 support, and what reference options are available?
The R5F100JHGFA#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports multiple reference configurations: external VREFP/VREFM pins, internal 1.45 V reference (selectable only in HS mode), and AVDD/AVSS as reference - enabling flexible ratiometric or absolute measurements. This is documented in Section 1.1 "A/D converter" of the R01DS0131EJ0380 datasheet.
Is the R5F100JHGFA#V0 qualified for industrial temperature range, and what grade letter indicates this?
Yes, the R5F100JHGFA#V0 is qualified for –40°C to +105°C operation, indicated by the 'G' suffix in its part number (R5F100JHGFA#V0). This G-grade certification meets industrial application requirements and is explicitly defined in Figure 1-1 "Part Number, Memory Size, and Package of RL78/G13" on Page 3 of the R01DS0131EJ0380 datasheet.
