FAQ
What is the maximum operating frequency and performance of the R5F100LDABG#U0?
The R5F100LDABG#U0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 μs in high-speed mode using the on-chip oscillator. This performance level supports real-time tasks such as motor control loops, sensor fusion, and protocol stack processing without external acceleration. The R5F100LDABG#U0 maintains this speed across its full 1.6–5.5 V supply range and -40°C to +105°C temperature envelope.
Does the R5F100LDABG#U0 include integrated data flash memory, and what are its endurance specifications?
Yes, the R5F100LDABG#U0 includes 8 KB of on-chip data flash memory with 1,000,000 write/erase cycles (typical) and background operation (BGO) capability. This allows the R5F100LDABG#U0 to execute program code from flash while simultaneously rewriting data flash - essential for logging, calibration storage, and over-the-air firmware updates. Data flash operates across the full VDD range of 1.8–5.5 V and supports sector protection to prevent accidental erasure of critical parameters.
What package type and pin count does the R5F100LDABG#U0 use, and is it RoHS-compliant?
The R5F100LDABG#U0 uses a 64-ball VFBGA package (4 × 4 mm, 0.4 mm pitch) with top-side ball layout, designated by the "BG" suffix and "#U0" tray packaging code. It is fully RoHS-compliant and rated MSL3 per JEDEC J-STD-020. This compact, high-density package supports fine-pitch PCB assembly and thermal performance suitable for space-constrained industrial modules - and is pin-compatible with other RL78/G13 variants in the same VFBGA-64 footprint.
How does the R5F100LDABG#U0 support low-power operation in battery-powered applications?
The R5F100LDABG#U0 supports ultra-low-power operation with 66 μA/MHz active current, 0.57 μA in HALT mode with only RTC and LVD active, and configurable STOP/SNOOZE modes. Its on-chip power-on-reset (POR) and 14-level voltage detector (LVD) enable robust brown-out recovery. In a typical battery-powered sensor node, the R5F100LDABG#U0 can wake every 60 seconds via RTC alarm, sample sensors, transmit data, and return to 0.57 μA mode - achieving multi-year operation on a single CR2477 cell.
What analog features are integrated into the R5F100LDABG#U0, and how are they applied in sensor systems?
The R5F100LDABG#U0 integrates a 10-bit ADC with 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor - all usable without external components. These features allow the R5F100LDABG#U0 to directly digitize thermistor, RTD, or voltage-output sensor signals while compensating for ambient temperature drift using its internal sensor. The ADC supports scan mode and hardware-triggered conversions synchronized to timers or peripherals - enabling precise, jitter-free sampling in environmental monitoring and predictive maintenance systems.
