The R5F3650NCDFA#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. Its minimum instruction execution time is 31.25 ns under these conditions, and it supports wait/stop power-saving modes to reduce active current consumption in battery-powered or thermally constrained designs. The R5F3650NCDFA#V0 maintains full peripheral functionality across this voltage range.
Does the R5F3650NCDFA#V0 support hardware-based HDMI CEC functionality?
Yes, the R5F3650NCDFA#V0 includes a dedicated CEC function block compliant with HDMI CEC standards, supporting transmit/receive, arbitration loss detection, and automatic ACK output at 32 kHz. This hardware acceleration eliminates the need for bit-banged software implementations and ensures timing accuracy required for interoperability with other CEC-enabled devices. The CEC signal is routed to pin P8_5 on the R5F3650NCDFA#V0.
What package type and pin count does the R5F3650NCDFA#V0 use?
The R5F3650NCDFA#V0 uses a 100-pin QFP package designated PRQP0100JD-B (previous code 100P6F-A), with 0.65 mm lead pitch and dimensions of 14 mm × 20 mm. It does not include an exposed thermal pad. This package is distinct from the 100-pin LQFP variant (PLQP0100KB-A) used by R5F3650NCDFB#V0, requiring separate PCB footprints and assembly profiles. The R5F3650NCDFA#V0 pinout is fully documented in Figures 1.6 and 1.7 of the datasheet.
How many analog input channels and what resolution does the A/D converter in the R5F3650NCDFA#V0 provide?
The R5F3650NCDFA#V0 integrates a 10-bit resolution A/D converter with 26 input channels, including sample-and-hold circuitry. Conversion time is specified at 1.72 µs, enabling high-speed acquisition for closed-loop control applications. Channels are distributed across ports P0, P2, P10, and P9 (ANEX0/ANEX1), with dedicated analog power pins (AVCC/AVSS) for noise-sensitive measurements. The R5F3650NCDFA#V0 supports simultaneous sampling only via external triggering, not true parallel conversion.
What is the operating temperature range certified for the R5F3650NCDFA#V0?
The R5F3650NCDFA#V0 is rated for an industrial operating temperature range of -40°C to +85°C, as indicated by the 'D' suffix in its part number. This qualification ensures reliable operation in harsh environments such as factory floors, outdoor equipment enclosures, and automotive cabin applications. Thermal performance is validated across the full voltage range (2.7–5.5 V) and maximum clock frequency (32 MHz), with no derating required within this envelope. The R5F3650NCDFA#V0 meets JEDEC JESD22-A104 reliability standards for temperature cycling.
