FAQ
What is the maximum operating frequency and corresponding DMIPS rating for R5F100LEAFA#10?
The R5F100LEAFA#10 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 41 DMIPS performance. This metric reflects its RL78 CPU core efficiency under typical code execution conditions, validated per Renesas benchmark methodology. The device also supports lower-frequency subsystem clocks (e.g., 32.768 kHz) for ultra-low-power RTC operation.
Does R5F100LEAFA#10 support LIN bus communication, and which pins are used?
Yes, R5F100LEAFA#10 supports LIN bus communication via its UART peripherals. Pins P11 (RxD0/TxD0) and P12 (TxD0) are configured as the primary LIN transceiver interface, compliant with ISO 17987-4. The on-chip LIN protocol support includes automatic sync-break detection and checksum handling, reducing firmware overhead in automotive body control modules.
What are the memory resources allocated to R5F100LEAFA#10, and how is data flash utilized?
R5F100LEAFA#10 includes 128 KB of code flash memory, 8 KB of dedicated data flash memory, and 12 KB of on-chip RAM. The data flash is designed for parameter storage (e.g., calibration coefficients, device IDs) and supports background operation (BGO), allowing code execution from main flash while rewriting data flash - critical for field-upgradable medical or industrial firmware.
Can R5F100LEAFA#10 operate from a single 3.3 V supply, and what is its minimum supply voltage?
Yes, R5F100LEAFA#10 operates reliably from a single 3.3 V supply and supports a wide voltage range of 1.6 V to 5.5 V. Its ability to function down to 1.6 V enables compatibility with partially discharged Li-ion cells or energy-harvesting sources, while maintaining full peripheral functionality including A/D conversion and RTC operation.
What packaging and lead finish does R5F100LEAFA#10 use, and is it RoHS-compliant?
R5F100LEAFA#10 uses a 64-pin LQFP package (12 × 12 mm, 0.65-mm pitch) with matte tin lead finish and complies with RoHS Directive 2011/65/EU and REACH regulations.
