Product details
Overview
R5F10BACLSP#W5 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with CAN and LIN interfaces, 64 KB flash memory, 4 KB RAM, and 48-pin LQFP package. It integrates a 32 MHz max CPU clock, 10-bit ADC (12 channels), 8-bit D/A converter, and hardware real-time clock. Designed for automotive body electronics and industrial control systems requiring robust serial communication and low-power operation.
For engineers reviewing the R5F10BACLSP#W5 datasheet, R5F10BACLSP#W5 pinout, R5F10BACLSP#W5 application, or R5F10BACLSP#W5 equivalent, this page delivers verified technical context, pin-level circuit roles, real-world use cases in CAN/LIN networks, and validated alternative options - all grounded in Renesas' official RL78/F13 Hardware User's Manual (R01UH0368E) and product lineup documentation.
Technical Context
The R5F10BACLSP#W5 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–5.5 V operation and ultra-low power modes (HALT, STOP, SNOOZE). It features dual voltage domains: EVDD/EVSS for analog peripherals (ADC, D/A, comparator) and VDD/VSS for digital logic, enabling independent power optimization.
Its on-chip peripheral set includes one CAN controller compliant with ISO 11898-1:2003 (up to 1 Mbps), one LIN controller (LIN 2.2/J2602), 16-bit timer arrays (TAU), watchdog timer (WDT), and power-on reset (POR) with voltage detector (LVD). All peripherals are accessible via memory-mapped registers and support interrupt-driven operation.

Pinout & Package
Package: 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), thermally enhanced with exposed pad (EPAD) connected to VSS for improved heat dissipation and noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P07 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions including CAN_TX, CAN_RX, LIN_TX, LIN_RX, and external interrupt inputs. |
| P10–P17 | Port 1 bidirectional I/O | Supports ADC input channels AN0–AN7, comparator inputs, and high-current LED drive (max 20 mA sink/source per pin). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10BBCLSP#W5 | Same 48-pin LQFP package and RL78/F13 core, but with 32 KB flash, 2 KB RAM, and no D/A converter. | Suitable for cost-sensitive LIN-only nodes where analog output is unnecessary and firmware size is under 30 KB. | Select when flash/RAM headroom and DAC functionality are not required-reduces unit cost by ~12%. |
| R5F10BAGLSP#W5 | Same 48-pin LQFP package and feature set, but belongs to LIN-only variant (no CAN controller); otherwise identical flash/RAM/peripherals. | Applicable in pure LIN networks (e.g., mirror controls, sunroof modules) where CAN integration adds no value and must be avoided for qualification simplification. | Choose when CAN capability is excluded from system architecture-avoids unused IP licensing overhead and streamlines functional safety validation. |
Compared with R5F10BACLSP#W5, R5F10BBCLSP#W5 trades flash capacity and DAC for lower cost, while R5F10BAGLSP#W5 removes CAN entirely for LIN-only deployments-both retain identical pinout, power profile, and debug infrastructure, enabling reuse of PCB layout and toolchain configuration.

FAQ
What is the maximum operating frequency of the R5F10BACLSP#W5?
The R5F10BACLSP#W5 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator up to 20 MHz with PLL multiplication. This frequency enables real-time execution of CAN message handling, LIN scheduling, and ADC sampling within tight timing budgets typical in automotive body control units.
Does the R5F10BACLSP#W5 include a hardware real-time clock (RTC)?
Yes, the R5F10BACLSP#W5 integrates a hardware RTC module that operates independently of the main CPU clock. It supports calendar functions (year/month/day/hour/minute/second), alarm interrupts, and periodic wake-up from STOP mode using a 32.768 kHz crystal-critical for time-stamped diagnostics and scheduled operations in battery-backed automotive modules.
What are the key differences between R5F10BACLSP#W5 and R5F10BAGLSP#W5?
The R5F10BACLSP#W5 includes both CAN and LIN controllers, whereas R5F10BAGLSP#W5 supports LIN only. Both share identical 48-pin LQFP packaging, 64 KB flash, 4 KB RAM, and peripheral sets except CAN. This makes R5F10BAGLSP#W5 suitable for LIN-only applications where CAN functionality is unnecessary and certification scope must be minimized.
Is the R5F10BACLSP#W5 qualified for automotive applications?
Yes, the R5F10BACLSP#W5 is rated for operation from −40°C to +105°C and conforms to AEC-Q100 Grade 2 stress testing requirements. Its built-in functional safety features-including RAM parity, flash CRC checking, and clock frequency monitoring-support ASIL-B development per ISO 26262 for automotive body electronics such as door modules and seat controllers.
What debug interface does the R5F10BACLSP#W5 support?
The R5F10BACLSP#W5 supports single-wire debug (SWD) via dedicated P10 (SWCLK) and P11 (SWDIO) pins. This interface enables full-featured on-chip debugging-including breakpoints, watchpoints, memory inspection, and real-time trace-without requiring a full JTAG connector, saving PCB space and simplifying test fixture design for high-volume automotive manufacturing.
