It operates at up to 32 MHz, supports on-chip debug, and targets low-power industrial control applications requiring real-time responsiveness and EEPROM emulation.

For engineers reviewing the R5F113GLCKFB#35 datasheet, R5F113GLCKFB#35 pinout, R5F113GLCKFB#35 application, or R5F113GLCKFB#35 equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral integration (including UART, I²C, SPI, and timer arrays), and direct alternative part comparisons for embedded system design and BOM optimization.

Technical Context

The R5F113GLCKFB#35 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–5.5 V operation and ultra-low power modes (HALT, STOP, and SNOOZE). Its on-chip voltage regulator supplies internal logic, and the 12-bit ADC achieves ±2 LSB INL with programmable sampling timing and hardware-triggered conversion sequencing.

Peripheral integration includes three 16-bit timer arrays (TAU) with complementary PWM output, a dedicated serial interface (CSI) for SPI-like communication, and dual I²C-compatible interfaces with clock stretching support. The device uses Renesas' proprietary Flash memory with background operation (BGO) and 100,000 write/erase cycles endurance.

FAQ

What is the maximum operating frequency of the R5F113GLCKFB#35?

The R5F113GLCKFB#35 supports a maximum CPU clock frequency of 32 MHz using its on-chip oscillator or external crystal input. This frequency is achievable across the full −40°C to +85°C temperature range when supplied with 2.7–5.5 V, and enables deterministic real-time execution of control loops with sub-microsecond interrupt latency. The R5F113GLCKFB#35 maintains timing compliance per RL78/F15 Hardware User's Manual Rev.1.10.

Does the R5F113GLCKFB#35 include hardware-based security features?

The R5F113GLCKFB#35 does not integrate cryptographic accelerators, secure boot ROM, or tamper detection. It supports basic security through flash memory lock bits, debug interface disable, and memory protection unit (MPU) configuration for privilege separation. For applications requiring certified security, external secure elements or higher-tier RL78 devices (e.g., RL78/G23 with AES engine) must be considered. The R5F113GLCKFB#35 prioritizes deterministic control over cryptographic processing.

Can the R5F113GLCKFB#35 operate from a single 3.3 V supply?

Yes, the R5F113GLCKFB#35 operates reliably from a single 3.3 V supply within its specified 1.6–5.5 V range. At 3.3 V, it delivers full 32 MHz performance, meets all AC/DC electrical specifications (including ADC accuracy and I/O drive strength), and supports all low-power modes. The internal voltage regulator automatically configures for optimal analog/digital domain partitioning without external components.

How many ADC channels does the R5F113GLCKFB#35 support, and what is their resolution?

The R5F113GLCKFB#35 integrates a single 12-bit successive-approximation ADC with 12 selectable input channels (AN0–AN11), supporting simultaneous sampling of up to two channels via hardware trigger. Its effective resolution is maintained at 12 bits with ±2 LSB integral nonlinearity across the full temperature range, and conversion time is programmable from 1.5 to 16 μs per sample depending on clock configuration.

Is the R5F113GLCKFB#35 pin-compatible with other RL78/F15 variants like the R5F113ML or R5F113PL?

No, the R5F113GLCKFB#35 is not pin-compatible with R5F113ML (80-pin) or R5F113PL (100-pin) variants. It belongs to the 48-pin RL78/F15 family subset and shares pinout only with other 48-pin members (e.g., R5F113GLxxx). Pin functions and physical layout differ significantly across package sizes, requiring separate PCB designs. Migration between packages necessitates schematic and layout revision, though firmware remains largely portable within the RL78/F15 software framework.
