FAQ
What is the maximum operating frequency of the R5F10BACLSP#G5?
The R5F10BACLSP#G5 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator. This frequency is fully supported across the full −40°C to +105°C operating range and enables sub-microsecond interrupt latency for time-critical automotive control tasks. The R5F10BACLSP#G5 maintains timing compliance without derating under worst-case voltage (1.6 V) and temperature conditions.
Does the R5F10BACLSP#G5 include a hardware real-time clock (RTC)?
Yes, the R5F10BACLSP#G5 integrates a hardware RTC with calendar function, powered by a dedicated 32.768 kHz sub-clock oscillator input. It supports alarm interrupts, periodic interrupts, and time-of-day tracking with leap-year compensation. The RTC remains operational in STOP mode with only 0.52 µA current draw, making it ideal for battery-backed applications such as automotive door modules and smart sensors where time-stamped event logging is required.
Is the R5F10BACLSP#G5 pin-compatible with other RL78/F13 devices in the 48-pin LQFP package?
Yes, the R5F10BACLSP#G5 shares identical pin assignment and electrical characteristics with other RL78/F13 48-pin LQFP variants (e.g., R5F10BBCLSP#G5, R5F10BGCLSP#G5), including identical placement of CAN_TX, CAN_RX, LIN_TX, LIN_RX, ADC inputs, and power pins. This allows drop-in replacement within the same package family for memory or peripheral scaling, provided firmware accounts for differences in flash size, RAM, or optional peripherals like the RTC.
What development tools are officially supported for the R5F10BACLSP#G5?
Renesas officially supports the R5F10BACLSP#G5 with the CS+ integrated development environment, e2 studio (Eclipse-based), and the E2 Lite on-chip debugger. Hardware tools include the E2 emulator and PG-FP6 flash programmer. All tools provide full access to the R5F10BACLSP#G5's debug interface, flash programming, and real-time trace capabilities without requiring additional adapters or license fees for basic functionality.
What is the qualification status of the R5F10BACLSP#G5 for automotive applications?
The R5F10BACLSP#G5 is qualified per AEC-Q100 Grade 2 (−40°C to +105°C) and designed for automotive body electronics applications. It incorporates ECC on flash and RAM, dual watchdog timers, and voltage monitoring features aligned with ISO 26262 ASIL-B requirements. While not certified as ASIL-B ready out-of-box, its hardware features enable system-level compliance when implemented with appropriate software safety mechanisms and diagnostic coverage.
