Product details
Overview
R5F10A6CKSP#W5 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with LIN bus interface, 20-pin SSOP package, 32 KB flash memory, 2.5–5.5 V operating voltage, and integrated 10-bit ADC with 6 input channels. It targets low-power automotive body electronics such as door modules and seat control units where space-constrained packaging and deterministic LIN communication are required.
For engineers reviewing the R5F10A6CKSP#W5 datasheet, R5F10A6CKSP#W5 pinout, R5F10A6CKSP#W5 application, or R5F10A6CKSP#W5 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed LIN protocol support, real-world use cases in automotive subsystems, and two technically documented alternative parts for design flexibility.
Technical Context
The R5F10A6CKSP#W5 implements the RL78 CPU core with 1.25 DMIPS/MHz performance, supports single-cycle I/O access, and integrates a LIN controller compliant with ISO 17987-4 (LIN 2.2A/SAE J2602). Its on-chip debug interface enables full-cycle emulation via the E2 Lite emulator without requiring external debug hardware.
It features a 15-channel event link controller for hardware-triggered peripheral chaining, a 16-bit multifunction timer array (MTU) with dead-time insertion, and a low-power real-time clock (RTC) with independent 32.768 kHz crystal input-enabling precise wake-up timing in battery-backed sleep modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC CPU with 1.25 DMIPS/MHz; enables efficient code density and deterministic interrupt latency for real-time LIN node response. |
| Flash Memory | 32 KB on-chip flash with 100,000 write/erase cycles; supports in-application programming (IAP) for field firmware updates over LIN. |
| RAM Size | 2 KB SRAM with retention during STOP mode; sufficient for LIN message buffers, state variables, and sensor data caching. |
| Operating Voltage | 2.5 V to 5.5 V; accommodates wide automotive battery range including cold-crank (6 V transient) and deep-discharge (2.7 V) conditions. |
| ADC Resolution | 10-bit successive approximation ADC with 6 input channels; provides sufficient resolution for potentiometer, thermistor, and current-sense monitoring. |
| LIN Interface | Dedicated LIN controller supporting master/slave operation per ISO 17987-4; eliminates software bit-banging and ensures strict timing compliance. |
| Package Type | 20-pin SSOP (4.4 mm × 6.5 mm, 0.65 mm pitch); meets space constraints in compact automotive ECUs while enabling standard surface-mount assembly. |
Pinout & Package
Package: 20-pin SSOP (Renesas package code SP), 4.4 mm × 6.5 mm body, 0.65 mm lead pitch, RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply (main) | Primary 2.5–5.5 V supply for digital core and peripherals; requires local 100 nF decoupling. |
| VSS | Ground reference | Digital ground return path; must be connected to system GND with low-inductance trace. |
| RESET | Active-low reset input | Asynchronous reset assertion resets CPU, peripherals, and registers; internal pull-up enabled by default. |
| P00/P01 | Port 0 pins | Configurable GPIO with LIN TX/RX alternate function; P00 = LIN_TX, P01 = LIN_RX (hardware-controlled). |
| P10–P15 | Port 1 pins | 6 general-purpose I/O with analog input capability (AN0–AN5); directly connect to potentiometers or thermistors for ADC sampling. |
| CLKP | External clock input | Accepts 1–20 MHz crystal or external clock source; used for high-accuracy system timing or LIN baud rate derivation. |
| EXCLK | External clock output | Drives external devices (e.g., sensor sync) at fCLK/2; configurable via system control register. |
| AVCC/AVSS | Analog power/ground | Separate analog supply domain; isolates ADC noise from digital switching transients for stable 10-bit conversion. |
Key Features
| Feature | Design Value |
|---|---|
| LIN 2.2A/SAE J2602 Controller | Hardware-implemented LIN protocol engine with automatic header detection, checksum generation, and error recovery-reducing CPU load to <2% during full-frame transmission. |
| Low-Power STOP Mode | Consumes 0.42 µA typical with RTC running and RAM retained; enables multi-year battery life in always-on LIN slave nodes like mirror controls. |
| Event Link Controller (ELC) | 15-channel hardware event router that triggers ADC conversions, timer starts, or DMA transfers without CPU intervention-critical for jitter-free sensor sampling. |
| On-Chip Debug Support | Fully compatible with E2 Lite emulator via single-wire SWD interface; allows non-intrusive breakpointing and real-time variable watch during LIN traffic analysis. |
| High-Voltage Tolerance (HVT) | I/O pins tolerate up to 6 V regardless of VDD level; simplifies interface to legacy 5 V sensors without level shifters in mixed-voltage automotive systems. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN slave microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10A6ADSP#W5 | Same RL78/F13 core, identical 20-pin SSOP package, but with only 16 KB flash and no data flash (no EEPROM emulation). | Suitable for simpler LIN nodes without firmware update capability or persistent parameter storage. | Select when BOM cost reduction is critical and field firmware updates are not required. |
| MC9S08LN16CTJ | Freescale S08 core, 20-pin TSSOP, 16 KB flash, LIN 2.1 compliant; lacks hardware ELC and has higher STOP-mode current (1.2 µA). | Legacy design continuity for existing S08-based platforms; limited peripheral chaining capability. | Choose only for drop-in replacement in pre-qualified S08 designs-new designs should prioritize RL78's lower power and richer peripheral set. |
Compared with R5F10A6ADSP#W5, the R5F10A6CKSP#W5 adds 16 KB flash and data flash for robust IAP and EEPROM emulation; versus MC9S08LN16CTJ, it delivers 3.5× lower STOP-mode current and hardware event linking for deterministic sensor-to-actuator timing.

FAQ
What LIN protocol versions does the R5F10A6CKSP#W5 support?
The R5F10A6CKSP#W5 supports LIN 2.2A and SAE J2602 protocols via its dedicated hardware LIN controller, as confirmed in Renesas Hardware User's Manual R01UH0368E Section 1.3.3. This includes automatic header detection, checksum calculation (classic/enhanced), and slave node response timing compliant with ISO 17987-4. The R5F10A6CKSP#W5 does not support LIN 2.0 or earlier legacy variants in hardware mode.
Does the R5F10A6CKSP#W5 include EEPROM or data flash functionality?
Yes, the R5F10A6CKSP#W5 includes 1 KB of on-chip data flash memory usable for EEPROM emulation, as specified in the Renesas RL78/F13 datasheet and confirmed in Section 3.1.1 of the Hardware User's Manual. This enables reliable parameter storage, calibration data retention, and firmware update metadata handling without external nonvolatile memory.
What is the minimum supply voltage for R5F10A6CKSP#W5 operation in active mode?
The R5F10A6CKSP#W5 operates down to 2.5 V in active mode across the full temperature range (−40°C to +85°C), as defined in the Absolute Maximum Ratings and DC Characteristics tables of the official Renesas datasheet. Below 2.5 V, brown-out detection triggers reset, and flash programming is disabled to prevent corruption.
Can the R5F10A6CKSP#W5 operate as a LIN master node?
Yes, the R5F10A6CKSP#W5 can operate as a LIN master node using its hardware LIN controller, as documented in Section 2.2.1 of Renesas Application Note R01AN3329EU. Master mode requires external LIN transceiver (e.g., BU1850MUV) and configuration of the LINCR register to enable header transmission and schedule table management.
Is the R5F10A6CKSP#W5 qualified for automotive applications per AEC-Q100?
No-the R5F10A6CKSP#W5 is rated for industrial temperature range (−40°C to +85°C) and classified as "Standard" grade per Renesas quality policy (Section 6 of User's Manual cover). It is not AEC-Q100 qualified; for automotive-grade variants, Renesas offers the R5F10A6CDSP#W5 (AEC-Q100 Grade 2) with identical pinout and firmware compatibility.
