FAQ
What is the maximum operating frequency and core performance of the R5F100JHDFA#X0?
The R5F100JHDFA#X0 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0%), delivering 41 DMIPS. Its RL78 CPU core features a 3-stage pipeline CISC architecture with minimum instruction execution time of 0.03125 μs in high-speed mode, and supports flexible clock scaling down to 32.768 kHz for ultra-low-power RTC operation.
Does the R5F100JHDFA#X0 include data flash memory, and what is its endurance?
Yes, the R5F100JHDFA#X0 includes 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing CPU code execution from program memory during data flash rewrites - essential for reliable logging and firmware parameter updates in fielded R5F100JHDFA#X0 systems.
What analog capabilities does the R5F100JHDFA#X0 provide for sensor interfacing?
The R5F100JHDFA#X0 integrates a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. These features enable direct ratiometric measurement of resistive sensors (e.g., thermistors, strain gauges) and ambient temperature compensation - critical for precision analog acquisition in R5F100JHDFA#X0-based sensor nodes.
How does the R5F100JHDFA#X0 support low-power design in battery-operated applications?
The R5F100JHDFA#X0 achieves industry-leading low-power operation: 66 μA/MHz active current, 0.57 μA in RTC+LVD-only mode, and configurable HALT/STOP/SNOOZE states. Its SNOOZE mode permits serial interface wake-up (e.g., UART frame detection) without full core restart - enabling responsive yet ultra-efficient R5F100JHDFA#X0 implementations in remote monitoring devices.
Is the R5F100JHDFA#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 52-pin LQFP-0.65mm package (e.g., R5F100Jx, R5F101Jx) share identical pinouts and electrical characteristics. This allows hardware reuse across memory/configurations - for example, R5F100JHDFA#X0 (256 KB flash, 8 KB data flash) and R5F101JHDFA#X0 (256 KB flash, 0 KB data flash) are pin-for-pin compatible, simplifying BOM rationalization and design scalability for R5F100JHDFA#X0-based platforms.
