Product details
Overview
R5F10A6ALSP#G5 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with LIN bus interface, 32 KB flash memory, 2.5 KB RAM, and 20-pin SSOP package. It operates at up to 24 MHz, supports on-chip debug, and integrates a 12-bit ADC, 8-bit D/A converter, and low-power real-time clock - deployed in automotive body control modules for LIN slave node communication.
For engineers reviewing the R5F10A6ALSP#G5 datasheet, R5F10A6ALSP#G5 pinout, R5F10A6ALSP#G5 application, or R5F10A6ALSP#G5 equivalent, key selection criteria include LIN physical layer compliance (ISO 17987-4), 1.8–5.5 V supply range, 1.25 μA deep standby current, and integrated voltage regulator enabling single-supply operation in space-constrained automotive sensors.
Technical Context
The R5F10A6ALSP#G5 implements the RL78 CPU core with 16-bit CISC architecture, 3-stage pipeline, and 1.25 DMIPS/MHz performance. It includes a dedicated LIN controller supporting master/slave modes, automatic baud rate detection, and LIN 2.2A/SAE J2602 protocol handling without software overhead.
On-chip peripherals include a 12-bit ADC with 8 input channels and ±1 LSB INL, an 8-bit D/A converter with 2-channel output, and a 16-bit multifunction timer (TM00–TM03) with complementary PWM generation - all synchronized to the same clock domain for deterministic timing in closed-loop sensor actuation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN slave microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08LN16CPJ | 8-bit S08 core, 16 KB flash, no integrated D/A, higher standby current (3.5 μA) | Limited analog capability; requires external DAC for ratiometric sensor excitation | Preferred where legacy S08 toolchain compatibility is required and analog integration is secondary |
| TLV320AIC3104IRHBR | Not a microcontroller - audio codec with LIN-capable GPIO; lacks CPU, flash, and ADC | Only suitable as peripheral companion IC, not standalone LIN node | Not a functional alternative; included only for context when co-designing with audio subsystems |
Compared with MC9S08LN16CPJ and TLV320AIC3104IRHBR, the R5F10A6ALSP#G5 delivers superior analog integration, lower power, and full LIN protocol offload - making it optimal for new designs requiring compact, self-contained LIN sensor nodes.

FAQ
What LIN protocol versions does the R5F10A6ALSP#G5 support?
The R5F10A6ALSP#G5 supports LIN 2.2A and SAE J2602 protocols via its dedicated hardware LIN controller. It handles sync-break detection, identifier filtering, checksum calculation (classic and enhanced), and automatic baud rate adjustment - all without CPU intervention. This ensures deterministic timing and reduced firmware overhead compared to bit-banged implementations in the R5F10A6ALSP#G5.
Does the R5F10A6ALSP#G5 include an internal voltage regulator?
Yes, the R5F10A6ALSP#G5 integrates an on-chip LDO regulator that generates a stable 1.25 V core supply from the main VDD input (1.8–5.5 V). A 1 μF ceramic capacitor must be connected to the REGC pin for regulation stability. This eliminates the need for an external regulator in most LIN node designs using the R5F10A6ALSP#G5.
What is the minimum supply voltage for reliable operation of the R5F10A6ALSP#G5?
The R5F10A6ALSP#G5 operates reliably down to 1.8 V across the full industrial temperature range (−40°C to +85°C). At this voltage, the maximum operating frequency is 8 MHz; full 24 MHz operation requires ≥2.7 V supply. This wide voltage range supports direct interfacing with both 3.3 V and 5 V automotive subsystems in the R5F10A6ALSP#G5.
Can the R5F10A6ALSP#G5 operate in deep standby mode with the RTC running?
Yes, the R5F10A6ALSP#G5 supports deep standby mode with the real-time clock (RTC) active while consuming only 1.25 μA. The RTC continues counting using the on-chip sub-clock oscillator (32.768 kHz), and the device can wake via external interrupt (e.g., P140) or LIN activity. This capability is essential for always-on functions in the R5F10A6ALSP#G5.
How many analog input channels does the R5F10A6ALSP#G5 ADC support?
The R5F10A6ALSP#G5 features a 12-bit successive approximation ADC with 8 selectable input channels (AN0–AN7), accessible via ports P10–P13 and P30–P33. It supports single-ended measurement with either internal 1.45 V reference or VDD as reference voltage - enabling flexible sensor interfacing in the R5F10A6ALSP#G5.
