FAQ

What is the maximum operating frequency of the R5F72395BDFP#V0?

The R5F72395BDFP#V0 operates at a maximum frequency of 100 MHz when powered within its specified 3.0 V to 3.6 V supply range and with the internal PLL configured for optimal clock synthesis. This frequency is sustained across the full −40 °C to +105 °C operating temperature range and enables deterministic execution of time-critical automotive control tasks. The R5F72395BDFP#V0 achieves this performance using the SH-2A dual-issue RISC pipeline with five-stage execution.

Does the R5F72395BDFP#V0 include an integrated CAN controller?

Yes, the R5F72395BDFP#V0 integrates two independent CAN 2.0B-compliant controllers supporting bit rates up to 1 Mbps, with message objects, acceptance filtering, and automatic retransmission. These controllers are fully compatible with ISO 11898-1 physical layer standards when used with external CAN transceivers. The R5F72395BDFP#V0 uses these for automotive network communication in body control modules and gateways.

What package type and pin count does the R5F72395BDFP#V0 use?

The R5F72395BDFP#V0 is housed in a 144-pin LQFP package measuring 20 mm × 20 mm with 0.5 mm pitch. It provides 118 user-configurable I/O pins, including dedicated signals for CAN, SCI, I²C, ADC, and PWM. The package includes an exposed thermal pad for enhanced heat dissipation in automotive under-hood environments. This package is shared across the SH7239 Group, ensuring layout reuse for derivative designs.
