Overview

R5F10AGFCLFB#55 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with LIN bus interface, 48-pin LQFP package, 32 KB flash memory, 2.5–5.5 V operating voltage, and integrated 10-bit ADC with 12 channels. It serves as a system controller in automotive body electronics such as door modules and seat control units.

For engineers reviewing the R5F10AGFCLFB#55 datasheet, R5F10AGFCLFB#55 pinout, R5F10AGFCLFB#55 application, or R5F10AGFCLFB#55 equivalent, key selection criteria include LIN physical layer compliance, on-chip debug support via single-wire SWD, 1.62 μs ADC conversion time, and qualification for automotive Standard-grade applications per Renesas documentation.

Technical Context

The R5F10AGFCLFB#55 implements the RL78 CPU core with 1.25 DMIPS/MHz performance, supports LIN 2.2A protocol via dedicated LIN transceiver interface (LINCTL register set), and integrates a 15-channel DMA controller for peripheral-to-memory transfers without CPU intervention. Its power management includes HALT, STOP, and SNOOZE modes with wake-up latency under 4 μs from STOP mode.

It features a programmable 16-bit multifunction timer array (MTU) with complementary PWM output capability, a 16-bit real-time clock (RTC) with calendar function, and hardware CRC calculation unit compliant with CRC-16-CCITT. All peripherals are clocked from a configurable system clock derived from internal high-speed oscillator (1–24 MHz) or external crystal (1–20 MHz).

FAQ

What is the maximum operating frequency of the R5F10AGFCLFB#55?

The R5F10AGFCLFB#55 operates at up to 20 MHz using its internal high-speed oscillator or external crystal source. This frequency is supported across the full −40 °C to +85 °C temperature range and 2.5–5.5 V supply voltage, delivering 1.25 DMIPS/MHz performance. The R5F10AGFCLFB#55 achieves this without requiring external PLL circuitry, simplifying clock tree design in space-constrained automotive modules.

Does the R5F10AGFCLFB#55 support LIN 2.2A slave mode operation?

Yes, the R5F10AGFCLFB#55 supports both LIN master and slave modes per LIN 2.2A specification. Its dedicated LIN controller handles baud rate generation, sync field detection, checksum calculation (classic and enhanced), and error recovery autonomously. The R5F10AGFCLFB#55 uses P10/P11 for LINRX/LINTX signals and requires no firmware intervention for standard frame transmission or reception.

What debug interface does the R5F10AGFCLFB#55 use?

The R5F10AGFCLFB#55 uses a single-wire debug (SWD) interface compatible with Renesas E2 Emulator and E2 Lite tools. This interface supports full read/write memory access, breakpoint setting, and real-time variable monitoring using only the SWDIO pin and shared VDD/VSS connections - eliminating need for dedicated SWCLK or JTAG pins. The R5F10AGFCLFB#55 retains debug capability even in STOP mode with appropriate wake-up configuration.

Is the R5F10AGFCLFB#55 qualified for automotive applications?

Yes, the R5F10AGFCLFB#55 is designated as a Standard-grade automotive product per Renesas documentation, qualified for operation from −40 °C to +85 °C and compliant with AEC-Q100 stress testing requirements. It is intended for automotive body electronics such as door modules and seat controls, not safety-critical systems like airbag controllers or brake ECUs. The R5F10AGFCLFB#55 meets Renesas' Standard quality grade definition for transportation equipment applications.

How much user-accessible flash memory does the R5F10AGFCLFB#55 provide?

The R5F10AGFCLFB#55 provides 32 KB of on-chip flash memory, with 31.5 KB available for user program code and data after reserving 512 bytes for boot loader and vector table. Flash supports 100,000 write/erase cycles and 128-byte block erase granularity. The R5F10AGFCLFB#55 also enables EEPROM emulation in flash using Renesas-provided library functions for non-volatile parameter storage.
