FAQ

What is the maximum operating frequency and corresponding performance of the R5F100PLAFB#30?

The R5F100PLAFB#30 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator, enabling real-time execution of motor control algorithms, sensor fusion, and communication stacks without external clock sources. The R5F100PLAFB#30 maintains this performance across its full 1.6–5.5 V supply range and −40°C to +105°C operating temperature.

Does the R5F100PLAFB#30 support in-system programming and secure firmware updates?

Yes, the R5F100PLAFB#30 supports full in-system programming via its on-chip debug interface and self-programming capabilities. It includes boot swap functionality and flash shield window protection to prevent unauthorized access to code memory during field updates. The R5F100PLAFB#30 also enables background operation (BGO), allowing application code to run while data flash is rewritten - essential for safe, uninterrupted firmware upgrades.

What analog features are integrated into the R5F100PLAFB#30 for sensor interfacing?

The R5F100PLAFB#30 integrates a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. These features allow direct ratiometric measurement of resistive sensors (e.g., RTDs, thermistors) and voltage signals without external references or calibration components. The R5F100PLAFB#30's ADC operates across the full 1.6–5.5 V supply range, ensuring accuracy in variable-voltage industrial environments.

How does the R5F100PLAFB#30 achieve ultra-low power consumption in industrial applications?

The R5F100PLAFB#30 achieves ultra-low power via multiple hardware modes: HALT (0.65 μA), STOP (0.57 μA with RTC + LVD active), and SNOOZE (low-power peripheral operation while CPU sleeps). Its 66 μA/MHz active current, combined with a 32.768 kHz subsystem clock and programmable voltage detector, enables multi-year battery life in remote sensors and meters. The R5F100PLAFB#30's G-grade qualification ensures these power specs remain valid at +105°C ambient.

Is the R5F100PLAFB#30 pin-compatible with other RL78/G13 variants in the same package?

Yes, the R5F100PLAFB#30 shares identical pinout and electrical characteristics with all other RL78/G13 devices in the 100-pin LFQFP-0.5mm package (e.g., R5F100PKAFB#30, R5F100PJAFB#30), differing only in flash/RAM sizes and feature enablement. This allows hardware reuse across product tiers - for example, designing one PCB for multiple memory configurations. The R5F100PLAFB#30's pin mapping is fully documented in Renesas' R01DS0131EJ0380 datasheet Section 1.3.
