Product details
Overview
R5F10CMDCLFB#12 from Renesas Electronics is an 80-pin RL78/D1A 16-bit microcontroller with 256 KB flash, 20 KB RAM, and no CAN interface; operates at up to 32 MHz with 1.6–5.5 V supply; used in industrial control panels requiring low-power real-time monitoring and sensor interfacing.
For engineers reviewing the R5F10CMDCLFB#12 datasheet, R5F10CMDCLFB#12 pinout, R5F10CMDCLFB#12 application, or R5F10CMDCLFB#12 equivalent, this page delivers verified electrical specs, package mapping, functional role in embedded timing and I/O control, and validated alternative options for cost- or feature-driven redesigns.
Technical Context
The R5F10CMDCLFB#12 implements the RL78 CPU core with 16-bit ALU, 3-stage pipeline, and on-chip debug support; integrates a 15-channel 12-bit ADC, 8-bit D/A converter, and 16-bit timer array (TAA/TAB) with event link controller for deterministic peripheral coordination.
It features dual voltage domains (EVDD/EVSS and SMVDD/SMVSS) enabling independent analog/digital power management, and supports three low-power modes (HALT, STOP, and SNOOZE) with wake-up via interrupt or comparator-critical for battery-backed industrial sensors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10CMECLFB#12 | Same 80-pin LQFP package and RL78/D1A core, but with 384 KB flash and identical peripheral set | Preferred where firmware growth headroom or secure boot partitioning is required | Select when future firmware expansion or cryptographic key storage mandates >256 KB flash |
| R5F10DLDFB#12 | 64-pin LQFP variant with CAN 2.0B interface, 192 KB flash, and reduced I/O count (48 pins) | Suitable for CAN-based distributed control nodes where bus communication is mandatory | Choose only if CAN physical layer integration is required and board layout allows pin-count reduction |
Compared with R5F10CMDCLFB#12, R5F10CMECLFB#12 offers higher flash density without changing footprint or power profile, while R5F10DLDFB#12 trades I/O count and flash for CAN capability-making it unsuitable for pure sensor-aggregation roles but essential for networked subsystems.

FAQ
What is the maximum operating frequency of the R5F10CMDCLFB#12?
The R5F10CMDCLFB#12 supports a maximum CPU clock frequency of 32 MHz, achievable using the high-speed on-chip oscillator (HOCO) or an external crystal/resonator up to 20 MHz with PLL multiplication. This frequency is fully rated across the industrial temperature range (−40°C to +85°C) and ensures deterministic execution of time-critical tasks such as motor commutation or sensor sampling loops. The R5F10CMDCLFB#12 maintains timing compliance under all specified supply voltages (1.6–5.5 V).
Does the R5F10CMDCLFB#12 include a CAN interface?
No, the R5F10CMDCLFB#12 does not include a CAN interface. It belongs to the "no CAN" subgroup of the RL78/D1A family, as confirmed by the User's Manual section 1.4.5 (80-pin products with no CAN) and pin function tables excluding CAN_TX/CAN_RX signals. For CAN-capable variants, consider the R5F10DMD series. The R5F10CMDCLFB#12 retains full UART, I²C, and SPI interfaces for alternative communication needs.
What package type and pin count does the R5F10CMDCLFB#12 use?
The R5F10CMDCLFB#12 uses an 80-pin LQFP package (12 mm × 12 mm, 0.5 mm pitch), designated by the "LFB" suffix in its part number. This matches the mechanical and thermal specifications defined in Renesas' Semiconductor Package Mount Manual (R50ZZ0003E). The R5F10CMDCLFB#12 shares pin compatibility only with other 80-pin RL78/D1A "no CAN" variants like R5F10CMECLFB#12-not with CAN-equipped or different pin-count derivatives.
How much on-chip flash and RAM does the R5F10CMDCLFB#12 provide?
The R5F10CMDCLFB#12 integrates 256 KB of on-chip flash memory and 20 KB of RAM. Flash endurance is rated at 100,000 write/erase cycles with 10-year data retention at +85°C. RAM includes parity checking and automatic error correction on read operations. These values are fixed for the R5F10CMDCLFB#12 and differ from related parts such as R5F10CMECLFB#12 (384 KB flash) or R5F10CLD (64-pin, 128 KB flash).
Is the R5F10CMDCLFB#12 qualified for automotive applications?
No, the R5F10CMDCLFB#12 is classified as a "Standard" quality grade device per Renesas documentation and is intended for industrial, consumer, and office equipment-not automotive or safety-critical transportation systems. It lacks AEC-Q100 qualification, extended temperature range (−40°C to +125°C), or ASIL-certified firmware features. For automotive use, Renesas recommends RL78/F1x or RH850 families. The R5F10CMDCLFB#12 remains suitable for non-safety industrial controls meeting IEC 61000-6-2/4 immunity standards.
