FAQ

What is the maximum operating frequency of the R5F3650TDFB#V2 and under what voltage conditions?

The R5F3650TDFB#V2 operates at up to 32 MHz when supplied with VCC1 and VCC2 in the range of 2.7 V to 5.5 V. This maximum frequency is achievable across the full -40°C to +85°C operating temperature range, with minimum instruction execution time of 31.25 ns confirmed in the datasheet under these conditions. The on-chip PLL and high-speed oscillator (40 MHz ±10%) provide the clock source.

Does the R5F3650TDFB#V2 support HDMI-CEC functionality natively, and how is it implemented?

Yes, the R5F3650TDFB#V2 includes native CEC (Consumer Electronics Control) transceiver circuitry compliant with HDMI CEC standards. It is implemented on pin P8_5 (NMI/SD/CEC) and supports transmit/receive, arbitration loss detection, and automatic ACK output. The CEC block operates at 32 kHz using the internal oscillator, eliminating need for an external crystal or discrete CEC PHY IC.

How many A/D converter channels does the R5F3650TDFB#V2 have, and what is their resolution and conversion speed?

The R5F3650TDFB#V2 features a 10-bit resolution A/D converter with 26 input channels. Conversion time is specified as 1.72 µs per channel, enabled by integrated sample-and-hold circuitry. Channels include dedicated AN0–AN7 on Port 10 and additional analog inputs multiplexed onto Ports 0, 2, and 9 - all accessible without external signal conditioning in typical industrial sensor applications.

What package type and pin count does the R5F3650TDFB#V2 use, and is it RoHS compliant?

The R5F3650TDFB#V2 uses a 100-pin LQFP package designated PLQP0100KB-A (previous code: 100P6Q-A), measuring 14 mm × 14 mm with 0.5 mm lead pitch. Per Renesas documentation and product marking, this device is RoHS compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level 3 requirements for standard surface-mount assembly.

Can the R5F3650TDFB#V2 execute code from external memory, and what bus interface options does it support?

Yes, the R5F3650TDFB#V2 supports external memory expansion via its external bus interface, providing 1 MB base address space expandable to 4 MB. It supports separate or multiplexed bus formats, 8- or 16-bit data bus width, and 12/16/20-bit address bus configuration. Up to 8 wait states and 4 chip select outputs allow interfacing with diverse SRAM, NOR flash, and peripheral ICs across 3 V and 5 V logic domains.
