FAQ

What is the maximum operating frequency and corresponding performance of the R5F1008CGLA#U0?

The R5F1008CGLA#U0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and high-speed on-chip oscillator calibrated to ±1.0% accuracy across 1.8–5.5 V and -40°C to +85°C. At 32 MHz, minimum instruction execution time is 0.03125 μs, enabling deterministic real-time response in motor control and sensor fusion applications.

Does the R5F1008CGLA#U0 include integrated data flash memory, and what are its endurance specifications?

Yes, the R5F1008CGLA#U0 includes 4 KB of on-chip data flash memory, rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8–5.5 V. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash-critical for reliable firmware parameter storage and field calibration in industrial equipment.

What package type and pin count does the R5F1008CGLA#U0 use, and is it RoHS compliant?

The R5F1008CGLA#U0 uses a 25-pin WFLGA package (3 × 3 mm, 0.5 mm pitch) with embossed tape packaging indicated by the #U0 suffix. It is RoHS compliant and qualified for industrial temperature operation from -40°C to +105°C (G-grade). This ultra-compact package supports high-density PCB layouts in space-constrained applications like handheld instruments and smart sensors.

How does the R5F1008CGLA#U0 achieve ultra-low power consumption, and what are the key low-power modes?

The R5F1008CGLA#U0 achieves ultra-low power via multiple hardware-optimized modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE (low-power peripheral operation with CPU halted). These modes leverage the RL78's low-leakage process and configurable clock gating. The 0.57 μA STOP current enables multi-year battery life in always-on monitoring devices without compromising real-time wake-up capability.

Which communication interfaces are supported by the R5F1008CGLA#U0, and are they LIN-compliant?

The R5F1008CGLA#U0 supports UART, I²C, and CSI (Renesas' simplified SPI) interfaces. Its UART module is explicitly LIN-bus compliant per ISO 17987, supporting LIN 2.x frame formatting, automatic sync-break detection, and slave node functionality-making it suitable for automotive body electronics and industrial sub-networks requiring standardized serial communication with master-slave topology.
