FAQ
What is the maximum operating frequency and supply voltage range for the R5F3650MDFB#10?
The R5F3650MDFB#10 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 supports direct battery operation (e.g., 3.7 V Li-ion) and compatibility with legacy 5 V logic systems. The minimum instruction execution time is 31.25 ns under these conditions, enabling deterministic real-time response in motor control loops.
Does the R5F3650MDFB#10 support HDMI Consumer Electronics Control (CEC)?
Yes, the R5F3650MDFB#10 includes fully integrated CEC functionality on Pin P8_5, supporting transmit/receive, arbitration loss detection, and automatic ACK output at 32 kHz. It complies with HDMI CEC specifications and requires only an external 10 kΩ pull-up resistor to VDD_CEC (typically 3.3 V) to meet physical layer requirements - no external transceiver IC is needed.
What package type and pin count does the R5F3650MDFB#10 use?
The R5F3650MDFB#10 uses a 100-pin LQFP package designated PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch). This package replaces the older 100P6Q-A code and is RoHS-compliant. It features separate VCC1 (core/peripherals) and VCC2 (external bus) power domains, enabling mixed-voltage system design without level shifters.
How many A/D and D/A converter channels does the R5F3650MDFB#10 provide?
The R5F3650MDFB#10 integrates a 10-bit A/D converter with 26 input channels (including P10_0–P10_7, P0_0–P0_7, P2_0–P2_7, and P9_7) and two independent 8-bit D/A converters. The A/D includes sample-and-hold circuitry for simultaneous multi-channel acquisition, while the D/A outputs support analog biasing or setpoint generation in closed-loop control systems.
What debug capabilities are built into the R5F3650MDFB#10?
The R5F3650MDFB#10 features on-chip debug support compliant with Renesas E8/E8a debug interfaces, including address match interrupt (×4), on-board flash rewrite, and real-time trace capability. These features enable non-intrusive breakpoints, memory inspection, and firmware update in the field - critical for validating motor control algorithms and CEC protocol stacks without hardware probes.
