FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LLDFA#X0?

The R5F100LLDFA#X0 operates up to 32 MHz with a verified performance of 41 DMIPS. This rating is measured using the EEMBC CoreMark benchmark under standard conditions (VDD = 3.3 V, TA = 25°C) and reflects sustained integer throughput with all caches and pipelines active. The RL78 core achieves this via its 3-stage pipeline and efficient CISC instruction set, making the R5F100LLDFA#X0 suitable for real-time control tasks demanding deterministic timing.

Does the R5F100LLDFA#X0 include an integrated temperature sensor, and how is it accessed?

Yes, the R5F100LLDFA#X0 includes a factory-calibrated on-chip temperature sensor accessible via the 10-bit ADC. It is mapped to a dedicated analog input channel (typically ANIxx, confirmed in the device-specific register map) and provides ±3°C accuracy across the -40°C to +85°C range. The sensor output is digitized alongside other ADC channels, requiring no external components-reducing BOM cost and board area in thermal monitoring applications using the R5F100LLDFA#X0.

What packaging and lead pitch does the R5F100LLDFA#X0 use, and is it RoHS-compliant?

The R5F100LLDFA#X0 uses a 64-pin LQFP package with 0.65 mm lead pitch, 12 mm × 12 mm body size, and conforms to JEDEC standard PLQP0064JA-A. It is fully RoHS-compliant and halogen-free, qualified for industrial temperature operation (-40°C to +85°C). The #X0 suffix explicitly denotes embossed tape packaging for automated SMT placement-ensuring consistent feed reliability in high-volume production of boards using the R5F100LLDFA#X0.

How many UART/LIN channels does the R5F100LLDFA#X0 support, and are they hardware-independent?

The R5F100LLDFA#X0 supports up to four independent UART/LIN channels, each with dedicated registers, baud rate generators, and FIFO buffers. All four channels operate concurrently without resource contention-enabling simultaneous LIN bus communication, debug console output, and Modbus RTU slave interface. This capability is confirmed in the RL78/G13 hardware manual and directly applies to the R5F100LLDFA#X0 variant, making it ideal for multi-protocol industrial gateways.

What is the data flash endurance and rewrite voltage range for the R5F100LLDFA#X0?

The R5F100LLDFA#X0 provides 8 KB of on-chip data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full supply range of VDD = 1.8 V to 5.5 V. Background operation (BGO) allows code execution from main flash during data flash rewrites-ensuring zero-latency firmware updates or parameter saves. This specification is guaranteed per Renesas datasheet R01DS0131EJ0380 and applies identically to the R5F100LLDFA#X0.
