Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LLAFA#50 | Same 512 KB flash, 32 KB RAM, but 64-pin LQFP-0.65mm with identical pinout and feature set | Identical functional scope; differs only in internal mask revision and minor errata coverage | Select when requiring latest silicon revision with documented fixes for specific timing edge cases |
| R5F101LCAFA#50 | No data flash (0 KB); otherwise identical core, memory map, and peripheral complement | Suitable where EEPROM-like nonvolatile storage is handled externally or unnecessary | Choose to reduce cost and simplify qualification when data logging or field updates are not required |
Compared with R5F100LCAFA#50, R5F100LLAFA#50 offers identical functionality with updated mask ROM, while R5F101LCAFA#50 removes data flash to lower unit cost - making the latter optimal for fixed-parameter deployments where flash-based configuration storage is omitted.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LCAFA#50?
The R5F100LCAFA#50 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS performance. This benchmark reflects actual instruction throughput under typical code mix conditions and is validated per EEMBC CoreMark methodology. The RL78 core achieves this with its 3-stage pipeline and efficient CISC architecture - enabling deterministic real-time response in motor control and sensor fusion applications where the R5F100LCAFA#50 is commonly deployed.
Does the R5F100LCAFA#50 include on-chip debug capability, and what interface does it use?
Yes, the R5F100LCAFA#50 integrates a full on-chip debug circuit compliant with Renesas' standard debug protocol, accessible via a 2-pin SWD (Serial Wire Debug) interface. No external debug probe is required beyond a standard SWD-capable programmer/debugger such as E2 studio with E2 Lite or Segger J-Link. This capability is factory-enabled and supports breakpoints, watchpoints, memory inspection, and live register view - essential for rapid development and validation of firmware running on the R5F100LCAFA#50 in industrial environments.
What are the data flash endurance and rewrite voltage range specifications for the R5F100LCAFA#50?
The R5F100LCAFA#50 provides 8 KB of on-chip data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. This allows robust parameter storage and field firmware updates even in brown-out conditions where supply voltage dips transiently. Background operation (BGO) enables concurrent code execution during rewrites - a key design enabler for reliable data logging in applications like predictive maintenance systems built around the R5F100LCAFA#50.
How many analog input channels does the R5F100LCAFA#50 support, and what ADC resolution is available?
The R5F100LCAFA#50 integrates a 10-bit successive-approximation ADC with up to 26 configurable analog input channels (ANI0–ANI25), selectable across multiple I/O ports. It includes an internal 1.45 V reference voltage source and supports both ratiometric and absolute measurement modes via AVREFP/AVREFM pins. This eliminates external reference components in most sensor interface designs and ensures consistent accuracy across the 1.6 V to 5.5 V operating range - a critical capability for precision analog acquisition in systems using the R5F100LCAFA#50.
Is the R5F100LCAFA#50 pin-compatible with other RL78/G13 devices in the same package variant?
Yes, the R5F100LCAFA#50 is fully pin-compatible with all other RL78/G13 devices in the 64-pin LQFP-0.65mm package (PLQP0064JA-A), including R5F100LDAFA#50 through R5F100LLAFA#50 and their D/G-grade counterparts. Pin functions, power domains, and peripheral mappings are identical across this group - enabling hardware reuse and firmware scalability. This compatibility simplifies migration paths and reduces PCB redesign effort when selecting different flash/RAM configurations within the same R5F100Lx family, including the R5F100LCAFA#50.
