It operates at up to 25 MHz and supports industrial control applications requiring deterministic real-time response and embedded I/O management.
For engineers reviewing the R4F2113NFT#U0 datasheet, R4F2113NFT#U0 pinout, R4F2113NFT#U0 application, or R4F2113NFT#U0 equivalent, key selection criteria include its 100-pin LQFP package, 3.3 V supply compatibility, on-chip debug support via on-chip debugging controller, and qualification for Standard-grade industrial use per Renesas quality classification.
Technical Context
The R4F2113NFT#U0 implements the H8S/2113 CPU core with 32-bit internal data paths and 24-bit address space, supporting both big-endian and little-endian operation modes via software configuration. It integrates a clock pulse generator (CPG) with PLL-based frequency multiplication, enabling flexible system clock derivation from external crystals or oscillators.
Peripheral integration includes two 16-bit TPU channels with PWM output capability, one full-duplex SCI channel supporting asynchronous serial communication at up to 1 Mbps, and dual low-voltage detection circuits (LVD0 and LVD1) with independent threshold settings and interrupt generation. Reset sources include power-on reset, pin reset, watchdog timer reset, and low-voltage detection resets.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R4F2113NFP#U0 | Same die, 80-pin PQFP package; reduced pin count limits peripheral access (e.g., only one SCI channel enabled) | Suitable for cost-sensitive, space-constrained designs where full 100-pin I/O is unnecessary | Select R4F2113NFP#U0 when board layout area is limited and fewer peripheral interfaces are required. |
| R5F2113NFT#U0 | Successor device in same footprint; adds CAN 2.0B controller, enhanced DMA, and 256 KB flash | Required for applications needing CAN bus connectivity or larger firmware storage without changing PCB | Choose R5F2113NFT#U0 when future-proofing for CAN-based fieldbus integration or firmware expansion beyond 128 KB. |
Compared with R4F2113NFT#U0, the R4F2113NFP#U0 reduces I/O flexibility but lowers BOM cost and board area, while the R5F2113NFT#U0 extends functionality with CAN and memory-neither is pin-compatible, requiring layout revision for migration.

FAQ
What is the maximum operating frequency of the R4F2113NFT#U0?
The R4F2113NFT#U0 supports a maximum operating frequency of 25 MHz, achieved using the on-chip PLL with external crystal input (typically 4–8 MHz). This yields a 40 ns instruction cycle time for critical real-time tasks. The actual achievable frequency depends on supply voltage stability and ambient temperature, with full performance guaranteed across the −40 °C to +85 °C range at 3.3 V ±5%. R4F2113NFT#U0 does not support overclocking beyond datasheet-specified limits.
Does the R4F2113NFT#U0 include on-chip debug capability?
Yes, the R4F2113NFT#U0 integrates an On-Chip Debugging Controller (OCDC) supporting non-intrusive breakpoints, watchpoints, and real-time register/memory inspection via dedicated debug pins (BKGD, BKIN, BKOUT). No external emulator or ICE is required. Debug firmware resides in protected ROM, and OCDC remains functional across all operating modes except deep-stop. R4F2113NFT#U0 debug access is enabled by default after reset unless disabled via security fuse programming.
What are the supported supply voltage ranges for the R4F2113NFT#U0?
The R4F2113NFT#U0 operates from 3.0 V to 3.6 V for both core and I/O domains, with 3.3 V nominal. Operation below 3.0 V triggers LVD0 reset if enabled; operation above 3.6 V risks permanent damage. Decoupling requires minimum 100 nF ceramic capacitors per VCC–VSS pair, placed within 5 mm of each power pin. R4F2113NFT#U0 does not support split-rail or dual-supply configurations-the same voltage must be applied to all VCC pins.
How many serial communication interfaces does the R4F2113NFT#U0 provide?
The R4F2113NFT#U0 includes one full-duplex Serial Communication Interface (SCI0) compliant with UART/RS-232 electrical behavior, supporting asynchronous communication at baud rates up to 1 Mbps. SCI0 features programmable oversampling, framing error detection, parity generation/checking, and break signal generation. No additional UART, SPI, or I²C peripherals are integrated-R4F2113NFT#U0 relies on software bit-banging or external bridge ICs for other serial protocols.
Is the R4F2113NFT#U0 qualified for automotive applications?
No, the R4F2113NFT#U0 is classified by Renesas as a "Standard" quality grade device, intended for industrial, office, and consumer equipment-not transportation or safety-critical systems. It lacks AEC-Q100 qualification, extended temperature screening, or automotive-specific failure-in-time (FIT) reporting. For automotive use, Renesas recommends the RH850 or RL78/F1x families. R4F2113NFT#U0 may be used in non-safety automotive subsystems (e.g., infotainment accessories) only after full system-level validation and risk assessment.
