FAQ

What is the maximum operating frequency of the R5S72670W144FP#V0?

The R5S72670W144FP#V0 operates at a maximum CPU frequency of 120 MHz using its on-chip PLL clock generator. This frequency is achievable across the full industrial temperature range (−40°C to +85°C) when supplied with 3.3 V ±10% and configured with appropriate oscillator settings per the Hardware User's Manual Rev. 3.00. The R5S72670W144FP#V0 maintains cycle-accurate timing at this speed for real-time interrupt latency and deterministic code execution.

Does the R5S72670W144FP#V0 include hardware floating-point support?

Yes, the R5S72670W144FP#V0 integrates a full IEEE 754-compliant single-precision floating-point unit (FPU) as part of its SH-2A CPU core. This hardware FPU executes addition, multiplication, division, square root, and transcendental operations in fewer cycles than software emulation - critical for motor control algorithms like field-oriented control (FOC) and sensor fusion. The R5S72670W144FP#V0 FPU is fully supported by Renesas' compiler toolchain and debug tools.

What communication interfaces are integrated into the R5S72670W144FP#V0?

The R5S72670W144FP#V0 integrates two CAN 2.0B controllers, one USB 2.0 full-speed host/device controller with integrated PHY, six serial communication interfaces (SCI), and one I²C bus interface. These interfaces operate independently with dedicated DMA channels, enabling concurrent communication across automotive networks (CAN), PC connectivity (USB), and sensor/actuator links (SCI/I²C). The R5S72670W144FP#V0 does not support Ethernet or CAN FD.

Is the R5S72670W144FP#V0 pin-compatible with other SH7267 series devices?

Yes, the R5S72670W144FP#V0 shares identical pin assignment and electrical characteristics with other members of the SH7267 Group in the 144-pin LQFP package, including R5S72671W144FP#V0 and R5S72672W144FP#V0. Differences between these variants are limited to Flash size (1 MB vs 768 KB vs 512 KB) and optional peripheral enablement - all maintained within the same footprint and signal mapping. The R5S72670W144FP#V0 pinout is documented in Section 1.4 of the Hardware User's Manual Rev. 3.00.

What safety certifications apply to the R5S72670W144FP#V0?

The R5S72670W144FP#V0 is rated as a "High Quality" grade product per Renesas' quality classification, qualifying it for use in transportation equipment, safety systems, and medical devices not intended for life support. It meets AEC-Q100 Grade 2 reliability standards for automotive applications and supports functional safety development per ISO 26262 ASIL-B through hardware features including ECC on Flash and RAM, lockstep-capable peripherals, and independent watchdog timers. The R5S72670W144FP#V0 itself is not ASIL-certified, but enables ASIL-B system-level compliance.
