Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN-enabled microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10A6EDSP#G5 | Same core, flash, RAM, and LIN peripheral; differs only in package (20-pin SDIP vs. SSOP) and temperature grade (−40 to +85°C vs. −40 to +105°C). | SDIP package suits through-hole prototyping or legacy board rework; lower temp grade limits under-hood deployment. | Select when mechanical compatibility with existing SDIP footprints is required and ambient operating temperature stays ≤85°C. |
| MC9S08LN16CTJ | Freescale (NXP) 8-bit S08 core, 16 KB flash, no integrated D/A, LIN 2.1 only, different register map and toolchain. | Lacks on-chip D/A and advanced low-power modes; requires external components for some analog functions. | Choose only if migrating from legacy S08-based designs where software reuse outweighs performance and integration benefits of RL78. |
Compared with R5F10A6EKSP#G5, the R5F10A6EDSP#G5 offers identical functionality in a through-hole package with reduced temperature range, while the MC9S08LN16CTJ provides legacy 8-bit compatibility at the cost of integration, precision, and power efficiency.

FAQ
What is the maximum operating frequency of the R5F10A6EKSP#G5?
The R5F10A6EKSP#G5 operates at a maximum CPU clock frequency of 24 MHz, achievable using the on-chip oscillator with PLL or external crystal/resonator up to 20 MHz. This frequency supports real-time LIN frame processing, ADC sampling at ≥100 kSPS, and deterministic interrupt latency under 1.5 µs - all critical for automotive body control applications where the R5F10A6EKSP#G5 is deployed.
Does the R5F10A6EKSP#G5 include an integrated LIN transceiver?
No, the R5F10A6EKSP#G5 integrates a LIN protocol controller but not the physical layer transceiver. It requires an external LIN transceiver IC (e.g., TLE7259-3GE or BU1850MUV) connected to P00 (LINRX) and P01 (LINTX). The R5F10A6EKSP#G5 manages all protocol-level tasks including header detection, checksum, and error handling, while the external transceiver handles voltage level shifting and bus driving.
What debug interface does the R5F10A6EKSP#G5 support?
The R5F10A6EKSP#G5 supports Renesas' single-wire debug (SWD) interface via the RES# pin, enabling full-featured on-chip debugging including breakpoints, watchpoints, memory inspection, and real-time trace without occupying additional GPIO pins. This interface is compatible with E2 Emulator Lite and Renesas Flash Programmer tools, allowing rapid firmware development and field update validation for systems using the R5F10A6EKSP#G5.
Is the R5F10A6EKSP#G5 qualified for automotive applications?
Yes, the R5F10A6EKSP#G5 is manufactured in Renesas' automotive-grade process and specified for operation from −40°C to +105°C. It meets AEC-Q100 Grade 2 requirements and supports functional safety development per ISO 26262 ASIL-B, with built-in features like memory parity, clock failure detection, and independent watchdog timers - making it suitable for automotive door modules, seat controls, and lighting systems where the R5F10A6EKSP#G5 is commonly applied.
How much user-accessible flash memory does the R5F10A6EKSP#G5 provide?
The R5F10A6EKSP#G5 provides 32 KB of on-chip flash memory, with 31.5 KB available for user program code and data after reserving 512 bytes for the boot loader and vector table. This capacity accommodates full LIN protocol stack implementation (including diagnostic services per LIN 2.2A), application logic, calibration data storage, and future firmware updates - all within a single R5F10A6EKSP#G5 device without external memory.
