Product details
Overview
R5F10BBGKNA#U5 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with CAN and LIN physical layer support, 32-pin LSSOP package, 32 KB flash, 2.5 KB RAM, and integrated 10-bit ADC with 12 channels. It operates at up to 32 MHz, supports on-chip debug, and targets automotive body electronics and industrial control nodes requiring robust serial communication.
For engineers reviewing the R5F10BBGKNA#U5 datasheet, R5F10BBGKNA#U5 pinout, R5F10BBGKNA#U5 application, or R5F10BBGKNA#U5 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed CAN/LIN interface capability, real-world use cases in vehicle subsystems, and two manufacturer-validated alternative parts with documented functional and packaging differences.
Technical Context
The R5F10BBGKNA#U5 implements the RL78 CPU core with 16-bit CISC architecture, 3-stage pipeline, and low-power SNOOZE mode enabling sub-μA standby current. It integrates a CAN controller compliant with ISO 11898-1 (CAN 2.0B), a LIN master/slave controller per LIN 2.2A, and hardware CRC calculation for message integrity.
On-chip peripherals include a 10-bit ADC with sample-and-hold and programmable conversion timing, a 16-bit timer array unit (TAU) with PWM output and input capture, and a dedicated watchdog timer with independent clock source. All peripherals are accessible via memory-mapped I/O registers with interrupt vectoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RL78 16-bit CISC core with 3-stage pipeline and 32 MHz max operation - enables deterministic real-time response in safety-critical control loops. |
| Flash Memory | 32 KB on-chip flash with block erase and 100k write/erase cycles - sufficient for firmware with CAN protocol stack and diagnostics. |
| RAM | 2.5 KB SRAM with retention during STOP mode - supports data logging and state preservation across sleep/wake transitions. |
| CAN Interface | Integrated CAN controller (ISO 11898-1, CAN 2.0B) with 32 message objects and FIFO buffer - eliminates need for external CAN transceiver logic in basic node designs. |
| LIN Interface | Dedicated LIN controller supporting master and slave modes (LIN 2.2A), automatic baud rate detection, and checksum generation - enables direct connection to LIN bus without software bit-banging. |
| ADC | 10-bit successive approximation ADC with 12 input channels, 1.1 μs conversion time, and internal reference - suitable for sensor monitoring (temperature, voltage, position) in automotive modules. |
| Package | 32-pin LSSOP (7.6 × 10.2 mm, 0.65 mm pitch) - compact surface-mount footprint compatible with high-density PCB layouts in space-constrained ECUs. |
Pinout & Package
Package: 32-pin LSSOP (Low-profile Small Outline Package), JEDEC MO-153AC compliant, 7.6 mm × 10.2 mm body, 0.65 mm lead pitch, exposed thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual power domains: VDD (1.6–5.5 V) powers digital logic; VSS provides return path - supports wide-input automotive battery range with single-supply operation. |
| P00–P07 | Port 0 bidirectional I/O | 8-bit general-purpose port with NMI input on P00 and CANRX on P01 - enables system reset signaling and direct CAN physical layer interface without level-shifting. |
| P10–P17 | Port 1 bidirectional I/O | 8-bit port with CANTX on P10 and LINRX on P11 - allows full CAN+LIN dual-bus node implementation using only two pins from this port. |
| P30–P33 | Port 3 bidirectional I/O | 4-bit port with AD0–AD3 analog inputs - maps directly to first four ADC channels for sensor signal acquisition. |
| RESET | Active-low reset input | Asynchronous reset pin with internal pull-up - ensures reliable initialization under brown-out or ESD events when combined with external RC network. |
| REGC | Regulator capacitor terminal | Connects to 1.0 μF ceramic capacitor for internal LDO stabilization - critical for noise immunity in electrically harsh automotive environments. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated CAN + LIN controllers | Reduces BOM count by eliminating separate transceivers and protocol co-processors in body control modules. |
| Hardware CRC generator | Accelerates frame-level error checking for CAN/LIN messages, freeing CPU cycles for application logic. |
| SNOOZE mode with wake-on-CAN | Enables ultra-low-power operation (<1.5 μA) while retaining ability to respond to incoming CAN frames - ideal for always-on vehicle networks. |
| On-chip debug interface (FINE) | Supports non-intrusive real-time debugging and flash programming via single-pin SWD-compatible interface - simplifies production programming and field updates. |
| 10-bit ADC with sample-and-hold | Provides simultaneous sampling of multiple sensors (e.g., cabin temp + HVAC blower current) with <±2 LSB INL - meets ASIL-B sensor accuracy requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications with CAN and LIN support.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10BLGKNA#U5 | 64-pin LQFP package, 64 KB flash, 4 KB RAM, same peripheral set - larger memory and I/O count. | Used in complex body ECUs requiring additional CAN channels or more ADC inputs. | Select when design requires >32 KB code space or ≥20 GPIOs beyond R5F10BBGKNA#U5's 24 usable I/Os. |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB flash, dual CAN, no native LIN - higher performance but no LIN hardware acceleration. | Targeted at gateway modules needing high-speed CAN FD routing and Ethernet bridging. | Choose only if LIN functionality can be implemented in software or omitted; not drop-in compatible due to architecture and pinout mismatch. |
Compared with R5F10BBGKNA#U5, R5F10BLGKNA#U5 offers scalable memory and I/O for future feature expansion without changing software architecture, while SPC560B50L5 trades LIN integration for raw compute throughput and CAN FD readiness - making it unsuitable for cost-sensitive LIN-only nodes.

FAQ
What is the maximum operating temperature range for the R5F10BBGKNA#U5?
The R5F10BBGKNA#U5 is rated for operation from −40°C to +105°C ambient temperature, meeting the "Standard" quality grade per Renesas documentation and qualifying for under-hood automotive applications such as door modules and seat controllers where thermal stress is significant. This range is validated across all specified electrical parameters including flash endurance and ADC linearity.
Does the R5F10BBGKNA#U5 support CAN FD?
No, the R5F10BBGKNA#U5 implements a classical CAN 2.0B controller compliant with ISO 11898-1 only and does not support CAN FD data rates or extended frame formats. Its CAN peripheral is limited to 1 Mbit/s nominal bitrate with standard 11-bit identifiers. For CAN FD, designers must select higher-tier RL78/G23 or RA-family devices.
How many LIN channels does the R5F10BBGKNA#U5 support?
The R5F10BBGKNA#U5 includes one dedicated LIN controller supporting both master and slave modes per LIN 2.2A specification. It uses P11 for LINRX and supports automatic baud rate detection, checksum generation, and sleep/wake frame handling without CPU intervention - enabling single-wire LIN bus connectivity out-of-the-box.
Is the R5F10BBGKNA#U5 pin-compatible with other RL78/F13 32-pin variants?
Yes, the R5F10BBGKNA#U5 shares identical pinout and package (32-pin LSSOP) with other RL78/F13 32-pin members including R5F10BAGKNA#U5 and R5F10BCGKNA#U5. Differences between these variants are limited to flash size (16 KB/32 KB/48 KB) and RAM allocation - allowing hardware reuse across firmware variants during platform development.
What debug interface does the R5F10BBGKNA#U5 use?
The R5F10BBGKNA#U5 employs Renesas' FINE (Fast In-Circuit Emulator) debug interface, accessible via a single-pin SWD-compatible serial wire debug port. This enables non-intrusive real-time debugging, flash programming, and trace capabilities using E2 Lite or E2 emulators - eliminating the need for JTAG headers and reducing PCB footprint.
