It operates at up to 32 MHz, supports 1.6–5.5 V supply, and integrates a 12-bit ADC (24 channels), 16-bit timer array (TAU), and LIN bus interface. It targets low-power industrial control and sensor node applications requiring integrated analog peripherals and robust communication.

For engineers reviewing the R5F113PJCLFB#15 datasheet, R5F113PJCLFB#15 pinout, R5F113PJCLFB#15 application, or R5F113PJCLFB#15 equivalent, key selection criteria include its 64-pin LQFP package, 12-bit ADC resolution with hardware averaging, LIN v2.2 compliance, on-chip debug support via FINE, and data flash endurance of 100,000 erase/write cycles.

Technical Context

The R5F113PJCLFB#15 implements the RL78 CPU core with 3-stage pipeline and CISC architecture optimized for ultra-low power operation. It includes a programmable low-voltage detection (LVD) circuit with 8 selectable thresholds, a real-time clock (RTC) with calendar function, and a 16-bit watchdog timer with independent clock source.

Its peripheral set supports simultaneous operation of multiple serial interfaces: one LIN/UART channel, two I²C-compatible interfaces (RIIC), and one CSI interface. The device uses Renesas' proprietary "Simplified Flash" technology enabling fast programming and high reliability in industrial temperature range (−40°C to +85°C).

FAQ

What is the maximum operating frequency of the R5F113PJCLFB#15?

The R5F113PJCLFB#15 operates at a maximum CPU frequency of 32 MHz. This speed is achievable using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator. The device supports dynamic clock switching between internal oscillators and external sources without requiring a full reset, enabling flexible power-performance trade-offs in real-time applications. All timing specifications in the R5F113PJCLFB#15 datasheet assume operation within this 32 MHz limit.

Does the R5F113PJCLFB#15 support LIN bus communication natively?

Yes, the R5F113PJCLFB#15 includes a dedicated LIN interface compliant with LIN specification v2.2. It handles sync-break detection, checksum calculation, and frame formatting in hardware, reducing CPU load during communication. The LIN module shares pins with UART functionality and supports both master and slave node configurations. No external transceiver is required for basic LIN signaling, though a physical layer transceiver must be added for bus-level compliance.

How much data flash memory does the R5F113PJCLFB#15 provide, and what is its endurance?

The R5F113PJCLFB#15 provides 4 KB of on-chip data flash memory with EEPROM emulation capability. It guarantees 100,000 erase/write cycles per block and supports wear leveling through Renesas' supplied firmware libraries. This memory retains data during power loss and is used for storing calibration parameters, configuration settings, and event logs-critical for industrial applications requiring nonvolatile parameter retention without external EEPROM.

What are the low-power modes supported by the R5F113PJCLFB#15?

The R5F113PJCLFB#15 supports three primary low-power modes: HALT (0.25 μA), STOP (0.35 μA), and SNOOZE. HALT mode stops the CPU clock while retaining register and RAM contents; STOP mode disables all clocks except the RTC and LVD, preserving calendar time and wake-up capability. Both modes support wake-up via external interrupt, RTC alarm, or LIN activity-enabling responsive yet ultra-low-power operation in battery-powered R5F113PJCLFB#15 deployments.

Is the R5F113PJCLFB#15 qualified for industrial temperature range operation?

Yes, the R5F113PJCLFB#15 is rated for industrial temperature operation from −40°C to +85°C. It is classified as a Standard-grade Renesas product, qualified per IEC 60730 Class B requirements for automatic control equipment. Its electrical specifications-including ADC accuracy, oscillator stability, and flash write timing-are guaranteed across this full range. Thermal derating is not required, and no special layout or cooling measures are needed for standard industrial enclosure environments.
