FAQ
What is the maximum operating frequency of the R5F21368CDFA#30 and under what supply conditions?
The R5F21368CDFA#30 achieves a maximum operating frequency of 20 MHz when powered at VCC = 2.7–5.5 V. At lower supply voltages (1.8–5.5 V), the maximum frequency is reduced to 5 MHz to ensure stable operation. This dual-frequency capability allows flexible power/performance trade-offs in battery-powered or wide-input industrial systems.
Does the R5F21368CDFA#30 support real-time clock functionality with calendar mode?
Yes, the R5F21368CDFA#30 includes Timer RE - an 8-bit timer configured for real-time clock (RTC) mode that counts seconds, minutes, hours, and days of week. It operates autonomously using the 32 kHz XCIN/XCOUT crystal, maintaining timekeeping even in stop mode with only 2.0 µA current draw at 3.0 V.
How many PWM output channels does the R5F21368CDFA#30 provide, and which timer supports complementary output?
The R5F21368CDFA#30 provides up to six independent PWM outputs via Timer RD, including complementary PWM mode that generates synchronized high-side/low-side drive signals on three phase pairs (6 pins total) with configurable dead-time insertion - essential for brushless DC motor inverter control.
Is on-chip debug supported for the R5F21368CDFA#30, and what interface is used?
Yes, the R5F21368CDFA#30 includes full on-chip debug functionality accessible via a single-wire interface compatible with Renesas E1/E20 emulators. It supports breakpoints, watchpoints, register inspection, and on-board flash rewrite - enabling rapid firmware development and field updates without external debug hardware.
What is the data flash endurance specification for the R5F21368CDFA#30, and how is background operation implemented?
The R5F21368CDFA#30 data flash has an endurance of 10,000 erase/write cycles per block (1 KB × 4 blocks). Background operation (BGO) allows CPU code execution to continue uninterrupted while data flash is being erased or programmed - critical for fail-safe firmware updates in always-on systems like HVAC controllers or smart appliances.
