FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F101FDAFP#30?
The R5F101FDAFP#30 operates at up to 32 MHz with a measured performance of 41 DMIPS. This metric reflects its RL78 CPU core's efficiency in executing typical embedded control workloads, validated under standard test conditions per Renesas' R01DS0131EJ0380 specification.
Does the R5F101FDAFP#30 include data flash memory, and what is its endurance specification?
No, the R5F101FDAFP#30 does not include data flash memory - it belongs to the "101" series where data flash is omitted. The "100" series (e.g., R5F100FDAFP#30) provides 8 KB data flash rated for 1,000,000 write/erase cycles (TYP) at VDD = 1.8–5.5 V.
What package type and pin count does the R5F101FDAFP#30 use, and is it RoHS-compliant?
The R5F101FDAFP#30 uses a 44-pin LQFP package (10 × 10 mm, 0.8-mm pitch), designated by "FP" in the part number suffix. It is RoHS-compliant and meets JEDEC J-STD-020 moisture sensitivity level 3 requirements for standard surface-mount assembly.
Can the R5F101FDAFP#30 operate from a 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F101FDAFP#30 supports operation from 1.6 V to 5.5 V. At 1.8 V, the RL78 core, 10-bit ADC (with internal 1.45 V reference), RTC, UART, I²C, and GPIO retain full functionality - enabling direct interfacing with 1.8 V logic families without level translation.
What debug interface does the R5F101FDAFP#30 support, and is an external debugger required?
The R5F101FDAFP#30 supports on-chip debug via the FINE interface using the dedicated TOOLRxD/TOOLTxD pins (P11/P12). No external debug probe is required for basic programming and breakpoint debugging - Renesas E2 emulator or compatible tools provide full JTAG-equivalent capability through this 2-pin interface.
