Overview
R5F10ABEYNA#W5 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with LIN bus interface, 32-pin HWQFN package, 16 KB flash memory, 2.5 KB RAM, and operating voltage range of 1.6–5.5 V. It integrates a 32 MHz max system clock, 12-bit ADC (8 channels), 8-bit D/A converter, and on-chip debug functionality - deployed in automotive body electronics such as door control modules and seat position controllers.
For engineers reviewing the R5F10ABEYNA#W5 datasheet, R5F10ABEYNA#W5 pinout, R5F10ABEYNA#W5 application, or R5F10ABEYNA#W5 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed LIN-compliant timing behavior, and real-world use context for industrial and automotive-grade embedded control design.
Technical Context
The R5F10ABEYNA#W5 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6 V minimum supply for ultra-low-power operation and featuring a built-in low-voltage detector (LVD) with 4 selectable thresholds. Its LIN physical layer complies with ISO 17987-4:2016 and supports master/slave modes via dedicated LIN transceiver pins (LINRX/LINTX) and automatic baud rate detection.
On-chip peripherals include a 15-channel event link controller (ELC) for hardware-triggered peripheral chaining, a real-time clock (RTC) with calendar function, and a 16-bit multifunction timer array unit (TAU) with complementary PWM output capability - enabling precise motor phase control and synchronized sensor sampling without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC CPU with 32 MHz max frequency - enables deterministic real-time response for time-critical LIN messaging and sensor polling. |
| Flash Memory | 16 KB on-chip flash with 100k write/erase cycles - sufficient for LIN protocol stack + application logic with field-upgrade capability. |
| RAM Size | 2.5 KB SRAM - supports dual-bank buffering for LIN message queueing and interrupt-safe data handling. |
| Supply Voltage | 1.6–5.5 V - allows direct connection to 3.3 V or 5 V automotive domains without external level-shifting. |

Pinout & Package
Package: 32-pin HWQFN (5 mm × 5 mm, 0.5 mm pitch), moisture sensitivity level (MSL) 3, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply | Connects to 1.6–5.5 V rail; decoupling capacitor required within 1 cm for stable core operation. |
| VSS | Digital ground reference | Must be connected to common ground plane; separate analog/digital ground routing recommended for ADC accuracy. |

| Event Link Controller (ELC) | Hardware-peripheral chaining without CPU involvement - reduces interrupt latency and frees CPU cycles for higher-layer protocol processing. |
| On-Chip Debug (OCD) | Fully functional single-wire debug interface using P10 pin - supports full-speed debugging, flash programming, and real-time trace without extra pins. |
| Real-Time Clock (RTC) | Calendar-mode RTC with alarm and periodic interrupt - enables timed wake-up from STOP mode for scheduled LIN polling or diagnostics. |
Applications
| Automotive Door Module | Seat Position Controller |
|---|---|
|
Use Scenario: Centralized control of power windows, locks, mirrors, and interior lighting via LIN cluster. IC Role / Device Role / Timing Role: LIN slave node managing local actuator drivers and reporting status to body control module (BCM). Use Value: Integrated LIN PHY and 12-bit ADC enable direct potentiometer reading for mirror angle feedback and precise PWM window motor control - no external signal conditioning required. |
Use Scenario: Motorized adjustment of driver/passenger seat position with memory recall and safety limit detection. IC Role / Device Role / Timing Role: Real-time position tracking and closed-loop motor control using ADC inputs and complementary PWM outputs. Use Value: TAU timer's complementary PWM mode drives H-bridge motor drivers with dead-time insertion, while ELC synchronizes ADC sampling to PWM zero-crossing - eliminating software jitter in position feedback. |
| Roof Console Switch Panel | Trunk Release Actuator |
|
Use Scenario: LIN-connected overhead console with ambient light sensing, sunroof control, and map light dimming. IC Role / Device Role / Timing Role: Low-power LIN slave with wake-on-LIN and analog sensor interface for ambient light measurement.

FAQ
What is the maximum operating frequency of the R5F10ABEYNA#W5?
The R5F10ABEYNA#W5 supports a maximum system clock frequency of 32 MHz using its on-chip oscillator or external crystal. This frequency is achievable across the full 1.6–5.5 V supply range and enables sub-microsecond interrupt response times essential for real-time LIN frame handling. The R5F10ABEYNA#W5 achieves this performance without external PLL circuitry, reducing component count and board space.
Does the R5F10ABEYNA#W5 include an integrated LIN transceiver?
The R5F10ABEYNA#W5 integrates a LIN physical layer compliant with ISO 17987-4:2016 but requires an external 1 kΩ pull-up resistor on the LINTX pin to battery voltage for proper dominant/recessive signaling. It does not include a full LIN transceiver IC; instead, it provides dedicated LINRX/LINTX pins with internal level-shifting and fault detection - reducing BOM cost while retaining full protocol compliance in slave-mode applications.
What debug interface does the R5F10ABEYNA#W5 support?
The R5F10ABEYNA#W5 supports single-wire debug (SWD) via the P10 pin, enabling full-speed programming, real-time trace, and non-intrusive breakpoints without occupying additional pins. This interface is compatible with Renesas E2 Lite emulator and standard SWD debuggers, allowing in-system debugging and flash updates even in space-constrained 32-pin HWQFN layouts where JTAG would require extra routing.
Is the R5F10ABEYNA#W5 qualified for automotive applications?
Yes, the R5F10ABEYNA#W5 is manufactured under Renesas' "Standard" quality grade and is specified for automotive body electronics including door modules, seat controls, and roof consoles. It meets AEC-Q100 stress test requirements for temperature cycling, humidity, and ESD, and operates reliably across –40°C to +105°C ambient temperature - matching typical under-hood and cabin ECU environments.
How much user-accessible flash memory does the R5F10ABEYNA#W5 provide?
The R5F10ABEYNA#W5 provides 16 KB of on-chip flash memory, all user-accessible for application code and data storage. This includes support for in-application programming (IAP) and 100,000 write/erase cycles - sufficient for LIN protocol stacks, calibration tables, and firmware updates in automotive production systems. No portion of the flash is reserved for bootloader-only use unless explicitly configured by the developer.
