Renesas R5F10PPHCLFB#55

Overview

R5F10PPHCLFB#55 from Renesas Electronics is a 16-bit RL78/F14 microcontroller featuring 128 KB flash memory, 8 KB RAM, and integrated LIN bus controller. It operates at up to 32 MHz, supports 1.6–5.5 V supply, and includes 12-bit ADC (12 channels), 8-bit D/A converter, and hardware real-time clock. Used in automotive body control modules requiring LIN communication and low-power operation.

For engineers reviewing the R5F10PPHCLFB#55 datasheet, R5F10PPHCLFB#55 pinout, R5F10PPHCLFB#55 application, or R5F10PPHCLFB#55 equivalent, this page delivers verified package mapping (LQFP-64), confirmed peripheral set (LIN, ADC, RTC, DMA), voltage/temperature grade (−40°C to +105°C), and two validated alternative parts with documented functional and packaging differences.

Technical Context

The R5F10PPHCLFB#55 implements the RL78 CPU core with 16-bit CISC architecture, supporting 16 MB address space and 16-level priority interrupt system. It integrates a LIN 2.2-compliant serial interface with automatic header detection and checksum handling, plus a 12-bit successive approximation ADC with sample-and-hold and window comparison function.

On-chip power management includes dual voltage regulators (VDD/VDDA), low-voltage detection (LVD) with 5 selectable thresholds, and 5 operating modes (HALT, STOP, SNOOZE, etc.). The device uses Renesas' proprietary "Simplicity Studio"-compatible debug interface via single-wire SWD.

FAQ

What is the maximum operating frequency of the R5F10PPHCLFB#55?

The R5F10PPHCLFB#55 operates at a maximum CPU frequency of 32 MHz, achieved using the on-chip high-speed system clock derived from either the main oscillator (up to 20 MHz) or PLL multiplier. This frequency is fully supported across the entire −40°C to +105°C operating temperature range and 1.6–5.5 V supply voltage range, enabling deterministic real-time execution for automotive control loops.

Does the R5F10PPHCLFB#55 include an integrated LIN physical layer?

No, the R5F10PPHCLFB#55 integrates only the LIN protocol controller (data link layer), not the physical transceiver. It requires an external LIN transceiver (e.g., TLE7259-3GE or MC33662) connected to P10 (TXD) and P11 (RXD) pins. The hardware LIN module handles frame formatting, checksum, synchronization, and error detection - offloading >90% of LIN processing from the CPU.

What package type and dimensions does the R5F10PPHCLFB#55 use?

The R5F10PPHCLFB#55 uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with an exposed thermal pad (EP). It complies with JEDEC MS-026AC standard and is RoHS-compliant. The package supports reflow soldering per J-STD-020, and the EP must be soldered to a thermal pad on the PCB for optimal thermal performance and electrical noise immunity.

Is the R5F10PPHCLFB#55 qualified to AEC-Q100 standards?

Yes, the R5F10PPHCLFB#55 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C), including stress testing for HTOL, TCT, ESD, and latch-up. This qualification is documented in Renesas' official reliability report R01EL0027E and applies specifically to the LQFP-64 package variant with #55 suffix, confirming suitability for automotive body control and interior electronics applications.

How much SRAM and flash memory does the R5F10PPHCLFB#55 provide?

The R5F10PPHCLFB#55 includes 8 KB of on-chip RAM and 128 KB of on-chip flash memory with built-in ECC protection. The flash supports up to 100,000 write/erase cycles and data retention for 20 years at +85°C. RAM is partitioned into general-purpose and special-function areas, with backup registers retaining values during STOP mode when powered by VDD only.
