Does the R5F109GBKNA#W0G include hardware support for LIN communication?
Yes, the R5F109GBKNA#W0G integrates a dedicated LIN bus controller compliant with ISO 17987-4:2016. It supports automatic baud rate detection, LIN header checksum calculation, and response handling without CPU intervention-reducing firmware overhead and ensuring timing-critical compliance in automotive body networks.
What is the ADC resolution and accuracy specification for the R5F109GBKNA#W0G?
The R5F109GBKNA#W0G features a 12-bit successive-approximation ADC with ±2 LSB integral nonlinearity (INL) and ±1 LSB differential nonlinearity (DNL). It includes an internal 1.45 V reference and supports external reference inputs, enabling calibrated measurements with <±0.05% full-scale error under typical operating conditions.
How much EEPROM emulation capability does the R5F109GBKNA#W0G provide?
The R5F109GBKNA#W0G provides 4 KB of data flash memory configured for EEPROM emulation, supporting byte-level read/write with built-in wear leveling and error correction. This allows up to 100,000 write cycles per sector and retains data for 20 years at 85°C-sufficient for storing calibration coefficients, device configuration, and usage logs.
What low-power modes are available on the R5F109GBKNA#W0G and their typical current consumption?
The R5F109GBKNA#W0G offers three ultra-low-power modes: SNOOZE mode (0.42 µA, CPU halted, ADC active), HALT mode (0.35 µA, CPU and most peripherals halted), and STOP mode (0.23 µA, only RTC and LVD active). All modes retain RAM contents and support wake-up via external interrupt, timer, or LIN activity-ideal for battery-powered edge sensors.
