FAQ
What is the maximum operating frequency of the R5F100PJDFA#X0?
The R5F100PJDFA#X0 supports a maximum CPU clock frequency of 32 MHz using the high-speed on-chip oscillator, delivering 41 DMIPS performance. This speed is achievable across the full −40°C to +105°C industrial temperature range, with oscillator accuracy maintained at ±1.0% under specified VDD and temperature conditions.
Does the R5F100PJDFA#X0 include an integrated real-time clock (RTC)?
Yes, the R5F100PJDFA#X0 includes a fully featured RTC with calendar support (up to 99 years), alarm function, and automatic clock correction. It operates independently in STOP mode using the 32.768 kHz subsystem clock, consuming only 0.57 μA when active with LVD - enabling precise timekeeping in battery-backed applications.
How much data flash memory does the R5F100PJDFA#X0 provide, and what is its endurance?
The R5F100PJDFA#X0 provides 8 KB of on-chip 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 program execution from code flash while data flash is being rewritten - essential for reliable data logging and field calibration.
What low-power modes are supported by the R5F100PJDFA#X0?
The R5F100PJDFA#X0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA. HALT mode reduces current to 66 μA/MHz during active operation. These modes are controlled via dedicated instructions and status registers, enabling fine-grained power management in battery-powered industrial nodes.
Is the R5F100PJDFA#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100PJDFA#X0 is pin-compatible with all other RL78/G13 devices in the 100-pin LFQFP-0.5mm package (e.g., R5F100PJGFB#X0, R5F101PJDFB#X0), sharing identical pin configuration, electrical characteristics, and peripheral mapping - enabling hardware reuse across functional variants and temperature grades.
