Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LLAFB#X0 | Same core, memory, and peripherals but in 64-pin LFQFP (0.5-mm pitch); 100% pin-compatible with R5F100LLAFA#X0 except for mechanical footprint | Preferred where finer-pitch assembly is available and board space is constrained | Select when using automated placement equipment capable of 0.5-mm pitch; requires PCB redesign due to different land pattern |
| R5F101LLAFA#X0 | Identical package and pinout but lacks data flash (0 KB); otherwise matches R5F100LLAFA#X0 in flash, RAM, and peripherals | Suitable for cost-sensitive applications where nonvolatile parameter storage is handled externally | Choose when data flash is unnecessary and BOM cost reduction is prioritized over field-upgrade capability |
Compared with R5F100LLAFA#X0, R5F100LLAFB#X0 offers identical functionality in a smaller footprint but demands tighter assembly tolerances, while R5F101LLAFA#X0 removes data flash to lower unit cost-making it viable only when external EEPROM or cloud-based configuration replaces on-chip parameter storage.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LLAFA#X0?
The R5F100LLAFA#X0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This speed is achievable across the full 1.6–5.5 V supply range and −40°C to +85°C temperature range, with oscillator accuracy of ±1.0% under specified conditions. The R5F100LLAFA#X0 also supports lower-frequency modes (e.g., 32.768 kHz) for ultra-low-power RTC operation.
Does the R5F100LLAFA#X0 include an integrated temperature sensor and voltage reference?
Yes, the R5F100LLAFA#X0 includes an on-chip temperature sensor and a 1.45 V internal reference voltage source, both accessible via the 10-bit ADC. These features are available only in HS (high-speed main) mode and eliminate the need for external components in thermal monitoring and precision analog measurement applications. The sensor output is calibrated and documented in the device's electrical characteristics table.
How many serial communication interfaces does the R5F100LLAFA#X0 support, and which protocols are implemented?
The R5F100LLAFA#X0 supports up to 10 I²C/Simplified I²C channels, 4 UART/LIN channels (with LIN 2.2 compliance), and 8 CSI (Simplified SPI) channels. These interfaces are independently configurable and can operate concurrently. LIN support includes automatic sync-break detection and checksum generation, making the R5F100LLAFA#X0 suitable for automotive body electronics and industrial sub-networks.
What power-saving modes are available on the R5F100LLAFA#X0, and what is the lowest current consumption achievable?
The R5F100LLAFA#X0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at VDD = 3.0 V and TA = 25°C. Active-mode current is 66 μA/MHz. These values are measured and guaranteed per the R01DS0131EJ0380 datasheet, and all modes retain RAM content and selected register states.
Is the R5F100LLAFA#X0 pin-compatible with other RL78/G13 devices in the same package variant?
Yes, the R5F100LLAFA#X0 is fully pin-compatible with other RL78/G13 devices in the 64-pin LQFP-0.65mm package (e.g., R5F100LKAFA#X0, R5F100LJAFA#X0), sharing identical pin functions and electrical characteristics. Memory size and peripheral enablement vary by part number, but PCB layout remains interchangeable across this package group, simplifying design reuse and scalability.
