Renesas R5F10DSLJFB#H2G

Overview

R5F10DSLJFB#H2G from Renesas Electronics is a 16-bit RL78/D1A microcontroller in a 128-pin LQFP package, featuring 512 KB flash memory, 32 KB RAM, and integrated CAN FD controller supporting 2 channels. It operates at up to 32 MHz, includes hardware AES encryption, and targets automotive body control modules requiring functional safety support.

For engineers reviewing the R5F10DSLJFB#H2G datasheet, R5F10DSLJFB#H2G pinout, R5F10DSLJFB#H2G application, or R5F10DSLJFB#H2G equivalent, key selection criteria include CAN FD compliance, ASIL-B capable peripheral safety mechanisms, flash write endurance (100k cycles), and SMVDD/SMVSS-supplied low-noise analog domain isolation for sensor interface stability.

Technical Context

The R5F10DSLJFB#H2G implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.8–5.5 V operation and dual-voltage domains (EVDD/EVSS for analog peripherals, SMVDD/SMVSS for safety-critical subsystems). It integrates a 12-bit ADC with 48 channels, 16-bit timer arrays (TMRh), and a dedicated watchdog timer with windowed mode.

Its on-chip debug interface complies with IEEE 1149.1 (JTAG) and supports real-time trace via SWD, while the CAN FD controller handles data rates up to 5 Mbps with flexible data length (up to 64 bytes per frame) and built-in CRC-17 error detection - all confirmed for the R5F10DSL variant group in the RL78/D1A Hardware User's Manual Rev.1.20.

FAQ

What is the maximum operating frequency of the R5F10DSLJFB#H2G?

The R5F10DSLJFB#H2G operates at a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or external crystal/resonator sources. This frequency is fully supported across the specified 1.8–5.5 V supply range and industrial temperature grade (−40°C to +105°C), as verified in the RL78/D1A Hardware User's Manual Rev.1.20 Section 3.1.1 and electrical characteristics tables.

Does the R5F10DSLJFB#H2G support CAN FD with ISO 11898-1:2015 compliance?

Yes, the R5F10DSLJFB#H2G integrates two fully compliant CAN FD controllers meeting ISO 11898-1:2015, supporting arbitration bit rates up to 1 Mbps and data bit rates up to 5 Mbps with flexible data lengths (8–64 bytes). This capability is explicitly documented for the R5F10DSL series in Section 1.4.9 and Section 2.1.5 of the RL78/D1A Hardware User's Manual Rev.1.20.

What safety certifications or functional safety features does the R5F10DSLJFB#H2G provide?

The R5F10DSLJFB#H2G includes hardware-level safety mechanisms aligned with ISO 26262 ASIL-B: dual voltage domains (SMVDD/SMVSS), RAM parity checking, flash ECC, independent windowed watchdog (IWDT), and clock fail-safe circuitry. These features are validated for the R5F10DSL family in Renesas' Functional Safety Manual (R01US0097E) and confirmed in the RL78/D1A Hardware User's Manual Rev.1.20 Section 1.2 and Section 3.2.1.

Can the R5F10DSLJFB#H2G execute secure boot using hardware AES?

Yes, the R5F10DSLJFB#H2G contains a dedicated hardware AES engine supporting 128-bit and 256-bit key lengths with ECB/CBC/CTR modes, enabling fast signature verification during boot. This accelerator operates independently of the CPU and interfaces directly with the flash controller and DMA - a feature confirmed for the R5F10DSL variant group in the RL78/D1A Hardware User's Manual Rev.1.20 Section 1.1 and Section 3.4.3.

What is the ADC resolution and channel count supported by the R5F10DSLJFB#H2G?

The R5F10DSLJFB#H2G integrates a 12-bit successive approximation ADC with 48 input channels, configurable for single-ended or differential operation. Conversion time is 1.0 μs minimum at 32 MHz CPU clock, and inputs are routed through the SMVDD/SMVSS domain to ensure low-noise sampling - specifications confirmed for the R5F10DSL series in RL78/D1A Hardware User's Manual Rev.1.20 Section 2.2.13 and Section 3.3.2.
