Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PKAFB#X0 | Same core, memory, and peripherals; differs only in package: 100-pin LFQFP (0.5 mm pitch) vs. LQFP (0.65 mm pitch) | Requires PCB layout change due to finer pitch and smaller footprint; suited for space-constrained designs | Select when board area is critical and rework capability supports 0.5 mm pitch assembly |
| R5F101PKAFA#X0 | Omits data flash (0 KB); retains same code flash, RAM, peripherals, and package | Not suitable for applications requiring nonvolatile parameter storage or firmware field updates | Choose for cost-sensitive, fixed-function designs where data logging or OTA updates are unnecessary |
Compared with R5F100PKAFA#X0, R5F100PKAFB#X0 offers identical functionality in a denser package requiring tighter layout tolerances, while R5F101PKAFA#X0 removes data flash to reduce cost-making it viable only where persistent user data or firmware swap is not required.

FAQ
What is the maximum operating frequency and performance rating of the R5F100PKAFA#X0?
The R5F100PKAFA#X0 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. Its RL78 CPU core uses a 3-stage pipeline with variable instruction timing - achieving 0.03125 μs minimum execution time at full speed, and extending to 30.5 μs at 32.768 kHz for ultra-low-power RTC operation. This makes the R5F100PKAFA#X0 suitable for both responsive real-time control and extended battery-life applications.
Does the R5F100PKAFA#X0 include data flash memory, and what is its endurance specification?
Yes, the R5F100PKAFA#X0 includes 8 KB of on-chip data flash memory with a rated endurance of 1,000,000 write/erase cycles (typical). It supports background operation (BGO), allowing the CPU to execute code from program memory while data flash is being rewritten - essential for reliable firmware updates and parameter storage in field-deployed devices like the R5F100PKAFA#X0.
What communication interfaces are integrated into the R5F100PKAFA#X0, and which support LIN bus protocols?
The R5F100PKAFA#X0 integrates UART, I²C/Simplified I²C, and CSI (SPI-compatible) interfaces. Specifically, it includes up to four UART channels, two of which are LIN-capable and compliant with LIN 2.2 physical layer specifications. These UARTs support automatic LIN header detection, checksum calculation, and sleep/wake frame handling - enabling direct integration into automotive body control and industrial network nodes using the R5F100PKAFA#X0.
What is the operating temperature range and supply voltage specification for the R5F100PKAFA#X0?
The R5F100PKAFA#X0 is rated for industrial operation from -40°C to +85°C and supports a wide single-supply voltage range of 1.6 V to 5.5 V. This allows direct interfacing with 1.8 V, 2.5 V, and 3.3 V logic families, and enables robust operation in battery-powered, mains-connected, and harsh-environment applications - all within the specified limits of the R5F100PKAFA#X0.
How does the R5F100PKAFA#X0 support low-power system design, and what sleep modes are available?
The R5F100PKAFA#X0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with RTC and LVD active, it draws just 0.57 μA - enabling multi-year battery life. SNOOZE mode permits selective peripheral wake-up (e.g., UART receive, ADC trigger) while the CPU remains halted. These capabilities, combined with 66 μA/MHz active current, make the R5F100PKAFA#X0 ideal for energy-conscious embedded systems.
