Overview
R5F10DLECLFB#12 from Renesas Electronics is a 16-bit RL78/D1A microcontroller with CAN interface, 512 KB flash memory, 32 KB RAM, and 64-pin LQFP package. It operates at up to 32 MHz, supports 1-channel CAN 2.0B, and integrates 12-bit ADC, 16-bit timer arrays, and low-power SNOOZE mode for industrial control and automotive body electronics.
For engineers reviewing the R5F10DLECLFB#12 datasheet, R5F10DLECLFB#12 pinout, R5F10DLECLFB#12 application, or R5F10DLECLFB#12 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed CAN timing behavior, and real-world use cases in motor control, sensor fusion, and distributed vehicle networks - all derived from Renesas' official RL78/D1A Hardware User's Manual Rev.1.20.
Technical Context
The R5F10DLECLFB#12 implements the RL78 CPU core with 16-bit CISC architecture, Harvard memory structure, and on-chip debug support via SWD. Its peripheral set includes a 1-channel CAN controller compliant with ISO 11898-1:2015, supporting bit rates up to 1 Mbps and programmable message filtering.
Power management features include three low-power modes (HALT, STOP, SNOOZE), voltage detection (LVD) with 2.7–4.2 V thresholds, and internal voltage regulator enabling single-supply operation from 2.7–5.5 V. The device uses Renesas' SuperFlash® technology for 100,000 write/erase cycles and 20-year data retention.
Key Specifications

|---|---|
| CPU Core | RL78 16-bit CISC core with 32 MHz max clock; enables deterministic real-time response in closed-loop motor control. |
| Flash Memory | 512 KB on-chip flash with ECC and block erase; supports firmware updates without external memory or bootloader partitioning. |
| RAM | 32 KB SRAM with parity checking; sufficient for dual-bank CAN buffer handling and real-time task stacks in AUTOSAR-compliant designs. |
| CAN Interface | 1 × CAN 2.0B controller with 32 message objects and hardware timestamping; meets ISO 11898-1 timing requirements for 125 kbps–1 Mbps bus rates. |

64-pin LQFP (Renesas package code CLFB), 10 mm × 10 mm body, 0.5 mm lead pitch, exposed thermal pad (EP). RoHS-compliant, halogen-free, MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P07 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions including UART0 TX/RX, CSI0, and timer output; supports pull-up/pull-down and noise filter. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10DLDFB#12 | Same 64-pin LQFP package and RL78/D1A core, but with 384 KB flash and no CAN interface. | Limited to UART/I²C-based systems without CAN bus integration; unsuitable for automotive or industrial fieldbus networks. | Select only when CAN is not required and flash budget is ≤384 KB. |
| R5F10DPGGLFB#12 | 100-pin LQFP variant with identical 512 KB flash, 32 KB RAM, and 1-channel CAN, plus additional ADC channels and timers. | Supports larger sensor arrays and more complex motion control algorithms; requires PCB redesign due to pin count and layout change. | Choose when expanding I/O count or peripheral concurrency is needed beyond 64-pin constraints. |
Compared with R5F10DLDFB#12 and R5F10DPGGLFB#12, the R5F10DLECLFB#12 uniquely balances CAN capability, memory size, and compact 64-pin footprint - making it optimal for space-constrained CAN nodes where full 100-pin resources are unnecessary and CAN-less variants lack required connectivity.

FAQ
What is the maximum operating frequency of the R5F10DLECLFB#12?
The R5F10DLECLFB#12 supports a maximum CPU clock frequency of 32 MHz when powered within its specified 2.7–5.5 V supply range. This frequency is achievable using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator. At 32 MHz, the RL78 core delivers 31.25 DMIPS performance, sufficient for real-time motor control loops and CAN message processing with sub-millisecond latency. The R5F10DLECLFB#12 maintains timing compliance across its full industrial temperature range (−40°C to +105°C).
Does the R5F10DLECLFB#12 support CAN FD or only classical CAN 2.0B?
The R5F10DLECLFB#12 implements only classical CAN 2.0B (ISO 11898-1:2015), supporting data rates up to 1 Mbps and standard/extended frame formats. It does not support CAN FD features such as flexible data-rate switching, larger payload sizes (up to 64 bytes), or enhanced CRC. This limitation is explicitly documented in the RL78/D1A Hardware User's Manual Rev.1.20, Section 1.4.4 and Chapter 2 pin function tables. For CAN FD applications, designers must select other RL78 families like RL78/F14 or RA-series MCUs.
What is the flash endurance and data retention specification for the R5F10DLECLFB#12?
The R5F10DLECLFB#12 uses Renesas' SuperFlash® technology, rated for 100,000 program/erase cycles and guaranteed data retention of 20 years at 85°C ambient temperature. These specifications are validated per JEDEC JESD22-A117 and published in Renesas' RL78/D1A datasheet and reliability reports. The R5F10DLECLFB#12 also includes on-chip ECC for flash read integrity and automatic error correction during normal operation - critical for automotive firmware update resilience.
Is the R5F10DLECLFB#12 qualified to AEC-Q100, and if so, which grade?
Yes, the R5F10DLECLFB#12 is qualified to AEC-Q100 Grade 2, covering operation from −40°C to +105°C ambient temperature. This qualification is confirmed in Renesas' official RL78/D1A product brief and supported by test reports for HTOL, TC, ESD, and AC/DC parametric stability. As a "High Quality" grade device per Renesas' internal classification (User's Manual Notice §6), the R5F10DLECLFB#12 is approved for automotive body electronics, chassis subsystems, and industrial equipment requiring extended temperature reliability - but not for safety-critical powertrain or ADAS applications unless further system-level certification is performed.
How many ADC channels does the R5F10DLECLFB#12 support, and what is the resolution?
The R5F10DLECLFB#12 integrates a 12-bit successive approximation ADC with 24 input channels (AD00–AD23), selectable via software-controlled multiplexer. Conversion time is 1.0 μs per sample at maximum clock rate, and the ADC supports simultaneous sampling across multiple channels using hardware triggers from timers or CAN events. This capability is fully documented in Section 2.1.2 (64-pin products) and Chapter 12 of the RL78/D1A Hardware User's Manual Rev.1.20. The R5F10DLECLFB#12's ADC meets EN 61000-4-3 radiated immunity requirements when used with recommended decoupling and layout practices.
