FAQ
What is the maximum operating frequency of the R5F21336MYFP#V0?
The R5F21336MYFP#V0 supports a maximum operating frequency of 20 MHz when powered at 2.7–5.5 V using an external crystal or ceramic resonator on the XIN/XOUT pins. At lower supply voltages (1.8–5.5 V), the maximum frequency is 5 MHz to ensure timing margin and stability across the full voltage range.
Does the R5F21336MYFP#V0 support in-system programming via its serial interfaces?
Yes, the R5F21336MYFP#V0 supports on-chip debug and in-system flash rewriting via its UART0 interface using Renesas' standard flash programming protocol. This enables field firmware updates without requiring external programmers, provided the bootloader is implemented per Renesas Application Note R01AN1279.
What is the function of the CHxA, CHxB, and CHxC pins on the R5F21336MYFP#V0?
The CHxA, CHxB, and CHxC pins on the R5F21336MYFP#V0 are dedicated control outputs for the integrated Sensor Control Unit. They configure electrode drive/receive patterns during electrostatic capacitive touch sensing, enabling flexible layout of up to 18 independent touch channels with adaptive noise rejection.
Can the R5F21336MYFP#V0 operate from a single 3.3 V supply in all power modes?
Yes, the R5F21336MYFP#V0 operates fully across its specified voltage range of 1.8–5.5 V. At 3.3 V, it achieves typical current consumption of 3.5 mA (active), 3.5 µA (wait), and 2.0 µA (stop), making it suitable for 3.3 V battery-powered or regulated systems without level-shifting.
How many interrupt vectors does the R5F21336MYFP#V0 support, and what priority levels are available?
The R5F21336MYFP#V0 supports 69 interrupt vectors with 7 programmable priority levels. Each interrupt source-including INT0–INT3, key inputs KI0–KI3, timer overflows, UART events, and A/D conversion completion-can be assigned independently to one of the 7 levels to ensure deterministic real-time response in complex control applications.
