FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GAANA#00?
The R5F100GAANA#00 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline and supports dynamic clock switching between high-speed (1–32 MHz) and low-speed (32.768 kHz) oscillators. The 0.03125 μs minimum instruction execution time at 32 MHz enables responsive real-time control in applications such as motor commutation and sensor fusion-while maintaining compatibility with legacy 16-bit toolchains and debug infrastructure.
Does the R5F100GAANA#00 support hardware LIN communication, and how is it implemented?
Yes, the R5F100GAANA#00 supports hardware LIN communication through its UART peripheral, which includes dedicated LIN-mode features per ISO 17987-4: automatic sync-break detection, checksum generation (classic/enhanced), and configurable baud rate. This eliminates software overhead for LIN frame assembly and validation, enabling reliable slave-node operation in automotive body electronics. The R5F100GAANA#00's integrated LVD and RTC further support functional safety requirements in LIN-based door modules and lighting controllers.
What are the power consumption characteristics of the R5F100GAANA#00 in low-power modes?
The R5F100GAANA#00 delivers industry-leading low-power operation: 66 μA/MHz in HALT mode, 0.57 μA in STOP mode with RTC and LVD active, and configurable SNOOZE mode for background ADC or serial transfers. These values are measured at VDD = 3.0 V and TA = 25°C. The 0.57 μA STOP current enables decade-long battery life in metering and sensor applications, while the on-chip POR and 14-level LVD ensure robust startup and brown-out recovery without external components.
How much flash and RAM does the R5F100GAANA#00 integrate, and what are their usage models?
The R5F100GAANA#00 integrates 128 KB of code flash memory (organized in 1 KB blocks), 8 KB of data flash memory (rated for 1 million erase/write cycles), and 12 KB of on-chip RAM. Code flash stores firmware and constants; data flash retains calibration data, device configuration, and event logs with background operation (BGO) support; RAM hosts stack, heap, and real-time variables. The flash library reserves specific RAM regions (e.g., FF300H for R5F100xD variants) for self-programming operations-details are documented in R20UT2944.
Is the R5F100GAANA#00 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GAANA#00 is pin-compatible with all other RL78/G13 devices in the 48-pin HWQFN package (e.g., R5F100GCANA#00, R5F100GHANA#00), sharing identical pin functions, electrical characteristics, and mechanical footprint. This enables scalable design reuse: developers can migrate between memory/configurations (e.g., 16 KB → 128 KB flash) without PCB revision. Pin mapping is fixed per the RL78/G13 hardware manual, and all variants support the same I/O drive strengths, voltage tolerances, and peripheral multiplexing.
