Renesas R5F10BAFLSP#G5

Overview

R5F10BAFLSP#G5 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with LIN bus interface, 32-pin LSSOP package, 16 KB flash memory, 2.5 KB RAM, and operating voltage range of 2.4–5.5 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 control modules and industrial sensor nodes requiring low-power, deterministic communication.

For engineers reviewing the R5F10BAFLSP#G5 datasheet, R5F10BAFLSP#G5 pinout, R5F10BAFLSP#G5 application, or R5F10BAFLSP#G5 equivalent, key selection criteria include LIN physical layer compliance, 32-pin LSSOP thermal performance, flash endurance (100k write/erase cycles), and support for single-wire LIN 2.2A transceiver integration without external level-shifting.

Technical Context

The R5F10BAFLSP#G5 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6 µA deep standby current and sub-1 µs interrupt latency. It features a programmable LIN controller with automatic sync-break detection, checksum generation, and configurable baud rate (1–20 kbps) - all managed via dedicated SFRs without CPU intervention.

Its peripheral set includes a 12-bit ADC with sample-and-hold and window comparison, an 8-bit D/A converter with internal reference, and a 16-bit timer array unit (TAU) with complementary PWM output capability. All peripherals are clocked from the on-chip oscillator or external crystal (1–20 MHz), with independent clock gating for power optimization.

FAQ

What LIN protocol versions does the R5F10BAFLSP#G5 support?

The R5F10BAFLSP#G5 supports LIN 2.2A and SAE J2602 protocols via its dedicated hardware LIN controller. It implements full ISO 17987-4:2016 compliance including automatic sync-break detection, configurable baud rate (1–20 kbps), and checksum generation for both classic and enhanced checksum models. The R5F10BAFLSP#G5 does not support LIN 2.1 or earlier legacy variants without firmware adaptation.

Does the R5F10BAFLSP#G5 require an external LIN transceiver?

No, the R5F10BAFLSP#G5 integrates a LIN physical layer driver capable of direct connection to the LIN bus through P00 (LIN_TX) and P01 (LIN_RX). It meets ISO 17987-3 electrical specifications for dominant/recessive voltage levels and slew rate control. An external transceiver is only needed if extended ESD protection (>±8 kV contact) or galvanic isolation is required - otherwise, the R5F10BAFLSP#G5 operates as a self-contained LIN node.

What is the maximum ADC sampling rate achievable with the R5F10BAFLSP#G5?

The R5F10BAFLSP#G5 achieves up to 1.15 MSPS maximum sampling rate using its 12-bit successive approximation ADC when configured with shortest conversion time (6.5 µs per sample) and triggered by internal TAU timer. Real-world sustained throughput is typically 500 kSPS due to software overhead and channel switching delays. The R5F10BAFLSP#G5 ADC supports hardware averaging (2–32 samples) to improve effective resolution at lower rates.

Can the R5F10BAFLSP#G5 operate from a 3.3 V supply without level shifters?

Yes, the R5F10BAFLSP#G5 operates natively across 2.4–5.5 V, making it fully compatible with standard 3.3 V logic and power domains. Its I/O pins are 5 V tolerant when configured as inputs, and its LIN interface functions correctly at 3.3 V supply - eliminating need for external level shifters in 3.3 V systems. The R5F10BAFLSP#G5's internal voltage regulator maintains stable core voltage regardless of supply variation within spec.

Is the R5F10BAFLSP#G5 qualified for automotive applications?

The R5F10BAFLSP#G5 is manufactured under Renesas' "Standard" quality grade and is rated for operation from −40°C to +85°C ambient temperature. While widely used in automotive body electronics (e.g., door modules, seat controls), it is not AEC-Q100 qualified. For ASIL-B or safety-critical applications, Renesas recommends the RL78/F14 series or RH850 family instead. The R5F10BAFLSP#G5 meets ISO/TS 16949 manufacturing requirements but requires customer-level validation for automotive deployment.
