Yes, the R5F10EBEGNA#20 supports LIN 2.2 bus communication through UART2 with dedicated LINSEL pin. This hardware-assisted implementation offloads protocol handling from the CPU, reducing software overhead and ensuring timing accuracy - a key capability confirmed in the R5F10EBEGNA#20 datasheet.
What are the low-power consumption figures for the R5F10EBEGNA#20 in different operational modes?
The R5F10EBEGNA#20 achieves 0.57 µA in Halt mode (RTC + LVD enabled), 0.23 µA in Stop mode (RAM retained), and 66 µA/MHz in active operation. These values are measured at VDD = 1.8–3.6 V and TA = −40°C to +105°C, making the R5F10EBEGNA#20 suitable for long-life battery-powered industrial devices.
How many analog input channels does the R5F10EBEGNA#20 support, and what is its ADC resolution?
The R5F10EBEGNA#20 integrates a 12-bit successive approximation ADC with 18 configurable analog input channels (ANI0–ANI29, excluding reserved numbers). Conversion time is 3.375 µs, and it supports internal 1.45 V reference and differential measurement using AVREFP/AVREFM - specifications confirmed for the R5F10EBEGNA#20 in its RL78/G1A family documentation.
What package type and pin count does the R5F10EBEGNA#20 use, and is the exposed pad internally connected?
The R5F10EBEGNA#20 uses a 32-pin HWQFN package (5 × 5 mm, 0.5 mm pitch) with an exposed die pad. The datasheet explicitly recommends connecting this pad to VSS for thermal and electrical stability - a critical layout requirement for reliable operation of the R5F10EBEGNA#20 in industrial environments.
