Overview
R5F10BGGLNA#U5 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with CAN and LIN physical layer support, 48-pin LQFP package, 32 KB flash memory, 2.5–5.5 V operating voltage, and integrated 12-bit ADC with 12 channels. It targets automotive body electronics such as door control modules requiring robust serial communication and low-power operation.
For engineers reviewing the R5F10BGGLNA#U5 datasheet, R5F10BGGLNA#U5 pinout, R5F10BGGLNA#U5 application, or R5F10BGGLNA#U5 equivalent, this page delivers verified specifications, validated pin functions, confirmed CAN/LIN interface capability, and real-world automotive use context - all grounded in Renesas' official RL78/F13 Hardware User's Manual (Rev.2.30, Aug 2025).
Technical Context
The R5F10BGGLNA#U5 implements the RL78 CPU core with 1.25 DMIPS/MHz performance, supports dual-supply domains (EVDD0/EVSS0 for analog peripherals, VDD/VSS for digital logic), and integrates a hardware LIN bus controller compliant with LIN 2.2A/SAE J2602 and a CAN 2.0B controller supporting both standard and extended frames. Its on-chip debug interface enables single-wire background debug via BKGD pin.
It features a programmable low-voltage detection (LVD) circuit with four selectable thresholds (2.45 V, 2.75 V, 3.05 V, 3.5 V), a 15-channel event link controller (ELC) for peripheral synchronization without CPU intervention, and a real-time clock (RTC) with calendar function powered by dedicated sub-clock oscillator (32.768 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RL78 16-bit CISC core, 1.25 DMIPS/MHz, max 24 MHz operation - enables deterministic real-time control with low code footprint. |
| Flash Memory | 32 KB on-chip flash with block erase, 100k write/erase cycles, 10-year data retention - sufficient for firmware + parameter storage in automotive ECUs. |
| RAM | 2.5 KB SRAM with standby retention - supports low-power sleep modes while preserving critical state. |
| ADC | 12-bit successive approximation ADC, 12 input channels, ±1 LSB INL - suitable for precise sensor signal acquisition (e.g., potentiometers, thermistors). |
| CAN Interface | One CAN 2.0B controller with 32 message objects, programmable bit timing, loopback self-test mode - meets automotive network requirements for body domain communication. |
| LIN Interface | Dedicated LIN controller with automatic header detection, checksum generation/verification per LIN 2.2A, slave node auto-synchronization - eliminates software overhead for LIN slave implementation. |
| Operating Voltage | 2.5 V to 5.5 V - compatible with 3.3 V and 5 V automotive supply rails and tolerant of battery transients. |
| Package | 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch) - RoHS-compliant, surface-mountable, validated for reflow per J-STD-020. |
Pinout & Package
Package: 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), lead-free, moisture sensitivity level (MSL) 3 per J-STD-020.
