FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100LLAFB#50?
The R5F100LLAFB#50 operates up to 32 MHz with a typical active current of 66 μA per MHz at VDD = 3.3 V and TA = 25°C. At full speed, this yields ~2.1 mA total active current. Its ultra-low-power STOP mode draws only 0.57 μA while maintaining RTC and LVD functionality - verified in the R01DS0131EJ0380 datasheet Section 1.1.
Does the R5F100LLAFB#50 support LIN bus communication, and which pins are used?
Yes, the R5F100LLAFB#50 supports LIN 2.2 via UART0 and UART1 with built-in break detection and sync field generation. Pins P10/SCK00/SCL00, P11/SI00/RxD0/TOOLRxD/SDA00, and P12/SO00/TxD0/TOOLTxD serve UART0; P30/RxD1 and P31/TxD1 serve UART1. No external LIN transceiver is required for basic node implementation.
What is the data flash endurance and rewrite voltage range for the R5F100LLAFB#50?
The R5F100LLAFB#50 includes 8 KB of data flash rated for 1,000,000 rewrite cycles (typical) with operation supported across VDD = 1.8 V to 5.5 V. Background operation (BGO) allows program execution from code flash while data flash is being rewritten - essential for logging sensor data without interrupting control loops.
How many ADC channels does the R5F100LLAFB#50 support, and what reference options are available?
The R5F100LLAFB#50 supports 26 analog input channels (ANI0–ANI25) with 10-bit resolution. Reference options include VDD (ratiometric), internal 1.45 V bandgap reference, or external AVREFP/AVREFM pins - enabling accurate measurements across varying supply conditions without external voltage references.
Is the R5F100LLAFB#50 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 64-pin LFQFP-0.5mm package (e.g., R5F100LKAFB#50, R5F101LLAFB#50) share identical pinouts and electrical characteristics. This allows drop-in replacement for memory or feature scaling - provided software accounts for differences in data flash presence or peripheral enablement.
