Renesas R5F10AACLSP#W5

Overview

R5F10AACLSP#W5 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with LIN bus interface, 32 KB flash memory, 2.5 KB RAM, and 30-pin SSOP package. It operates at up to 24 MHz, supports 10-bit ADC (8 channels), and integrates on-chip debug functionality for embedded control in automotive body electronics and industrial sensors.

For engineers reviewing the R5F10AACLSP#W5 datasheet, R5F10AACLSP#W5 pinout, R5F10AACLSP#W5 application, or R5F10AACLSP#W5 equivalent, this device is selected for cost-sensitive, low-power LIN node designs requiring deterministic real-time response, integrated voltage regulation, and AEC-Q100–qualified operation in ambient temperatures up to +105°C.

Technical Context

The R5F10AACLSP#W5 implements the RL78 CPU core with 16-bit CISC architecture, supporting 131 instructions and 3-stage pipeline execution. It includes a dedicated LIN controller compliant with ISO 17987-4 (LIN 2.2A/SAE J2602), hardware CRC generator, and on-chip power-on reset with voltage detector (1.6 V threshold).

It features dual-supply domains: EVDD/EVSS for analog peripherals (ADC, comparator) and VDD/VSS for digital logic, enabling independent noise isolation. The device uses Renesas' proprietary "Simplified Peripheral Control" architecture, allowing peripheral registers to be configured without CPU intervention via dedicated control blocks for timer arrays and serial interfaces.

FAQ

What is the maximum operating frequency of the R5F10AACLSP#W5?

The R5F10AACLSP#W5 operates at a maximum CPU clock frequency of 24 MHz, achieved using either the on-chip oscillator (with trimming), an external crystal (up to 20 MHz), or external clock input. Its 3-stage pipeline enables 1.25 DMIPS/MHz performance, delivering 30 DMIPS at full speed while maintaining low power consumption.

Does the R5F10AACLSP#W5 include an integrated LIN transceiver?

No, the R5F10AACLSP#W5 integrates a LIN protocol controller but not a physical layer transceiver. It provides LIN_TX (open-drain) and LIN_RX (Schmitt-trigger input) signals requiring an external LIN transceiver such as the TLE7259-3GE or BU1850MUV. This separation allows design flexibility and ESD robustness tuning.

What package type and pin count does the R5F10AACLSP#W5 use?

The R5F10AACLSP#W5 uses a 30-pin SSOP (Shrink Small Outline Package) with 7.6 mm × 10.2 mm body size and 0.65 mm lead pitch. It is RoHS-compliant, rated for industrial temperature range (–40°C to +105°C), and qualified to AEC-Q100 Grade 2 for automotive applications.

Can the R5F10AACLSP#W5 operate from a single 3.3 V supply?

Yes, the R5F10AACLSP#W5 supports single-supply operation at 3.3 V applied to both VDD and EVDD pins. Its internal LDO regulates core voltage to 1.25 V, and the ADC maintains full 10-bit linearity across 2.7–5.5 V supply range-enabling direct integration into 3.3 V systems without level-shifting.

Is the R5F10AACLSP#W5 qualified for automotive applications?

Yes, the R5F10AACLSP#W5 is AEC-Q100 Grade 2 qualified (–40°C to +105°C), with built-in features supporting automotive reliability: on-chip voltage detector, CRC hardware accelerator, flash error correction code (ECC), and LIN protocol compliance per ISO 17987-4. It is widely used in door modules, seat controls, and HVAC subsystems.
