Renesas R5F10PLHCLFB#55

Overview

R5F10PLHCLFB#55 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with CAN and LIN interfaces, 64-pin LQFP package, 512 KB flash memory, 32 KB RAM, and operating voltage range of 1.6 to 5.5 V. It integrates a 32 MHz max CPU clock, 12-bit ADC (24 channels), 16-bit timer arrays, and hardware LIN bus controller - deployed in automotive body control modules requiring robust serial communication and real-time I/O management.

For engineers reviewing the R5F10PLHCLFB#55 datasheet, R5F10PLHCLFB#55 pinout, R5F10PLHCLFB#55 application, or R5F10PLHCLFB#55 equivalent, key selection criteria include CAN 2.0B compliance, LIN 2.2/SAE J2602 support, flash endurance (100k write/erase cycles), on-chip debug interface (FINE), and AEC-Q100 Grade 2 qualification for under-hood automotive use.

Technical Context

The R5F10PLHCLFB#55 implements the RL78 CPU core with 16-bit CISC architecture, supporting both 8- and 16-bit instructions and low-power modes (HALT, STOP, SNOOZE). Its peripheral set includes dual CAN controllers (CAN0/CAN1) with message objects and FIFO buffers, a dedicated LIN master/slave controller with automatic checksum generation, and a 12-bit successive-approximation ADC with programmable sampling timing and window comparison.

It features integrated power management with on-chip voltage regulator (VDD = 1.6–5.5 V), independent reset sources (power-on reset, low-voltage detection, watchdog timer), and hardware encryption acceleration (AES-128). The device supports in-application programming (IAP) via flash memory segmentation and secure boot using ROM-based bootloader with signature verification.

FAQ

What is the maximum operating frequency of the R5F10PLHCLFB#55?

The R5F10PLHCLFB#55 supports a maximum CPU clock frequency of 32 MHz when using the high-speed on-chip oscillator or an external crystal. This frequency is achievable across the full −40 °C to +105 °C operating range and enables deterministic execution of real-time control tasks such as LIN frame transmission and ADC sampling within strict timing windows. The R5F10PLHCLFB#55 achieves this performance while maintaining low active current consumption (typically 90 μA/MHz).

Does the R5F10PLHCLFB#55 support both CAN and LIN simultaneously?

Yes, the R5F10PLHCLFB#55 integrates two independent CAN 2.0B controllers (CAN0 and CAN1) and two dedicated LIN controllers (LIN0 and LIN1), enabling concurrent operation on separate networks. Each LIN controller supports master/slave modes, auto-baud detection, and hardware checksum generation, while CAN controllers provide 32 message objects with FIFO buffering. This dual-network capability is confirmed in the RL78/F13 User's Manual Hardware (R01UH0368E) and is implemented in the R5F10PLHCLFB#55 silicon.

What package type and pin count does the R5F10PLHCLFB#55 use?

The R5F10PLHCLFB#55 uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This package is explicitly listed in the RL78/F13 product lineup tables and pin configuration diagrams (Section 1.5.5 of R01UH0368E). The "L" in the part number denotes the 64-pin variant, and "CLFB" confirms the LQFP-64 with lead-free, halogen-free finish per JEDEC standard.

Is the R5F10PLHCLFB#55 qualified for automotive applications?

Yes, the R5F10PLHCLFB#55 is AEC-Q100 qualified to Grade 2 (−40 °C to +105 °C), making it suitable for under-hood and interior automotive applications including body control modules and seat control units. This qualification is documented in Renesas' official product briefs and supported by reliability test reports covering HTOL, TC, HAST, and ESD. The R5F10PLHCLFB#55 also meets automotive functional safety requirements with built-in BIST, lockstep-capable peripherals, and failure monitoring features.

What debug interface does the R5F10PLHCLFB#55 support?

The R5F10PLHCLFB#55 supports the FINE (Fast In-Circuit Emulator) single-wire debug interface, which provides non-intrusive real-time tracing, breakpoints, and memory access without requiring additional pins beyond the standard SWDIO and SWCLK signals. This interface is fully compatible with Renesas E2 and E2 Lite emulators and enables secure firmware development and validation in production environments. The R5F10PLHCLFB#55 implements FINE v3.0 with enhanced security features including debug lock and encrypted session keys.
