FAQ

What is the maximum operating frequency and supply voltage range for the R5F3650NCNFB#V0?

The R5F3650NCNFB#V0 operates at up to 32 MHz with a supply voltage range of 2.7 V to 5.5 V on both VCC1 and VCC2 pins. This wide voltage range allows direct compatibility with legacy 5 V systems and modern 3.3 V designs without level-shifting circuitry. The minimum instruction execution time is 31.25 ns under these conditions, as confirmed in Renesas Document R01DS0015EJ0110, Table 1.1.

Does the R5F3650NCNFB#V0 support hardware CEC functionality, and what is its operating frequency?

Yes, the R5F3650NCNFB#V0 integrates dedicated CEC transmit/receive circuitry with arbitration lost detection and automatic ACK output, operating at 32 kHz as specified in Table 1.2 and Table 1.4 of the datasheet. Pin P8_5 serves as the bidirectional CEC I/O, enabling HDMI-CEC compliance without external transceivers - a key differentiator for TV and audio system designs.

How many A/D converter channels does the R5F3650NCNFB#V0 have, and what is their resolution and conversion time?

The R5F3650NCNFB#V0 features a 10-bit A/D converter with 26 input channels and an on-chip sample-and-hold circuit. Its conversion time is 1.72 µs, as documented in Table 1.2 and Table 1.4. This performance supports high-speed sampling of temperature, current, and voltage feedback signals in motor control and power supply monitoring applications.

What package type and pin count does the R5F3650NCNFB#V0 use, and is it RoHS compliant?

The R5F3650NCNFB#V0 uses a 100-pin LQFP package designated PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch), per Figure 1.7 and Table 1.4. While RoHS compliance is not explicitly stated in R01DS0015EJ0110, Renesas standard product policy confirms RoHS-6 compliance for all M16C/65C Group devices manufactured after 2006 - including R5F3650NCNFB#V0.

Can the R5F3650NCNFB#V0 execute code from external memory, and what bus configurations does it support?

Yes, the R5F3650NCNFB#V0 supports external memory expansion with a 1 MB base address space extendable to 4 MB. It offers configurable bus formats (separate or multiplexed), data bus widths (8 or 16 bits), and address bus sizes (12/16/20 bits), with 0–8 wait states and four chip select outputs - enabling flexible interfacing with SRAM, NOR flash, and FPGA peripherals as detailed in Table 1.1 and Table 1.3.
