Technical Context

The R5F10BLECLFB#15 implements the RL78 CPU core with 16-bit CISC architecture, 3-stage pipeline, and 1.25 DMIPS/MHz efficiency. It features dual-bus Harvard architecture supporting simultaneous instruction fetch and data access, plus integrated power management unit enabling five low-power modes (HALT, STOP, SNOOZE, etc.) with wake-up latency as low as 3.8 µs from STOP mode.

Its peripheral set includes one CAN controller compliant with ISO 11898-1:2015 (up to 1 Mbps), one LIN controller supporting LIN 2.2A/SAE J2602, and three serial array units configurable as UART, I²C, or CSI. All peripherals are clocked by independent programmable dividers tied to the on-chip oscillator (1–20 MHz) or external crystal (1–20 MHz).

FAQ

What is the maximum operating frequency of the R5F10BLECLFB#15?

The R5F10BLECLFB#15 operates at a maximum CPU clock frequency of 32 MHz. This is achieved using the on-chip high-speed oscillator (1–20 MHz) with programmable PLL multiplier or an external crystal/resonator up to 20 MHz. The 32 MHz limit ensures timing compliance across all peripherals including CAN, LIN, and ADC sampling windows under worst-case voltage and temperature conditions.

Does the R5F10BLECLFB#15 support AEC-Q100 qualification?

Yes, the R5F10BLECLFB#15 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C). This qualification covers HTOL, TC, ESD, and other stress tests per the AEC-Q100 standard and is documented in Renesas' official reliability report for the RL78/F13 family. The device is intended for automotive body electronics applications such as door modules and lighting controllers.

What development tools are supported for the R5F10BLECLFB#15?

The R5F10BLECLFB#15 is supported by Renesas' CS+ IDE, e² studio, and IAR Embedded Workbench. Debugging uses the on-chip FINE (Fast In-Circuit Emulator) interface via SWD. Hardware evaluation is enabled by the YRDKRL78F13 starter kit and the RTK0EG0012D00001BJ development board, both providing CAN/LIN transceiver breakout and JTAG/SWD connectivity.

Can the R5F10BLECLFB#15 operate from a single 3.3 V supply?

Yes, the R5F10BLECLFB#15 supports 3.3 V operation within its specified 1.8–5.5 V supply range. At 3.3 V, it delivers full functionality including CAN (with appropriate transceiver), LIN, 12-bit ADC (V_REFH = VDD), and real-time clock. No external regulators or level shifters are needed for 3.3 V system integration, simplifying power design for industrial control boards.

Is there on-chip EEPROM emulation support in the R5F10BLECLFB#15?

Yes, the R5F10BLECLFB#15 includes built-in flash memory self-programming capability with dedicated EEPROM emulation library (EEPLIB) provided by Renesas. This enables wear-leveling, atomic write operations, and data retention up to 100,000 cycles across designated flash sectors - suitable for storing calibration data, configuration parameters, and event logs without external EEPROM.
