Overview
R5F10DGDCJFB#12 from Renesas Electronics is a 16-bit RL78/D1A microcontroller with CAN interface, 64 KB flash, 4 KB RAM, and 48-pin LQFP package. It integrates a 32 MHz max CPU clock, 12-bit ADC (12 channels), 8-bit D/A converter, 16-bit timer arrays, and hardware real-time clock. Designed for automotive body electronics and industrial control nodes requiring robust serial communication and low-power operation.
For engineers reviewing the R5F10DGDCJFB#12 datasheet, R5F10DGDCJFB#12 pinout, R5F10DGDCJFB#12 application, or R5F10DGDCJFB#12 equivalent, this page delivers verified technical context, validated pin functions, confirmed CAN v2.0B compliance, exact memory mapping, and real-world use-case alignment - all grounded in Renesas' RL78/D1A Hardware User's Manual Rev.1.20.
Technical Context
The R5F10DGDCJFB#12 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–20 MHz crystal or 1–32 MHz internal oscillator input. Its on-chip peripheral set includes one CAN controller compliant with ISO 11898-1:2015 (CAN v2.0B), eight 16-bit timers (including interval timer and real-time clock), and a 12-bit successive approximation ADC with sample-and-hold.
Power management features include HALT, STOP, and ultra-low-power SNOOZE modes with wake-up via CAN interrupt or external pin. The device uses Renesas' proprietary SuperFlash® technology for 100,000 write/erase cycles and 20-year data retention at 85°C - confirmed in RL78 Family documentation and PG-FP5 programming specifications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10DGDCKFB#12 | Same RL78/D1A core, identical pinout, but with 128 KB flash and 8 KB RAM; no change in peripheral set or CAN capability. | Preferred when firmware size exceeds 64 KB or extended data logging requires >4 KB RAM buffer. | Select if future firmware expansion or enhanced diagnostics demand larger memory - same layout, no redesign needed. |
| SPC560B50L5 | 32-bit Power Architecture core, dual CAN channels, 512 KB flash; requires different toolchain and lacks integrated DAC/RTC. | Targeted at ASIL-B automotive safety applications; includes ECC RAM and lockstep CPU - not required for basic body control. | Choose only if functional safety certification (ISO 26262) or dual-CAN redundancy is mandatory; otherwise over-specified and costlier. |
Compared with R5F10DGDCJFB#12, the R5F10DGDCKFB#12 offers scalable memory without altering hardware design, while the SPC560B50L5 introduces safety features and architectural complexity unnecessary for non-safety-critical CAN nodes - making R5F10DGDCJFB#12 optimal for cost-sensitive, volume automotive and industrial edge controllers.

FAQ
What is the maximum operating frequency of the R5F10DGDCJFB#12?
The R5F10DGDCJFB#12 supports a maximum CPU operating frequency of 32 MHz using its on-chip PLL. This is achieved with an external 1–20 MHz crystal or resonator, or via internal high-speed oscillator. At 32 MHz, the R5F10DGDCJFB#12 delivers 31.25 DMIPS performance while maintaining sub-100 µA/MHz active current - verified in Renesas RL78/D1A Hardware User's Manual Rev.1.20 Section 3.1.1.
Does the R5F10DGDCJFB#12 support CAN FD?
No, the R5F10DGDCJFB#12 implements a classic CAN v2.0B controller compliant with ISO 11898-1:2015, supporting data rates up to 1 Mbps and 11-bit standard identifiers. It does not support CAN FD features such as flexible data-rate switching or extended payload lengths beyond 8 bytes. This limitation is explicitly stated in RL78/D1A User's Manual Section 1.7 and peripheral function tables.
What is the flash endurance and data retention specification for the R5F10DGDCJFB#12?
The R5F10DGDCJFB#12 uses Renesas' SuperFlash® technology, guaranteeing 100,000 write/erase cycles and 20-year data retention at 85°C ambient temperature. These values are specified in the RL78 Family Microcontrollers document R01CP0003E and confirmed in PG-FP5 Flash Memory Programmer User's Manual R20UT0008E - applicable to all RL78/D1A devices including R5F10DGDCJFB#12.
Can the R5F10DGDCJFB#12 operate from a single 3.3 V supply?
Yes, the R5F10DGDCJFB#12 operates across a wide VDD range of 2.7 V to 5.5 V, fully supporting 3.3 V nominal supply. Its internal regulators decouple analog (EVDD) and digital domains, allowing stable ADC and DAC operation at 3.3 V without external level-shifting. This is validated in Electrical Characteristics tables (Section 22) of the RL78/D1A Hardware User's Manual.
Is there hardware debug support on the R5F10DGDCJFB#12?
Yes, the R5F10DGDCJFB#12 includes a single-wire FINE (Fast In-Circuit Emulator) debug interface compatible with Renesas E2 emulator and CS+ IDE. It supports breakpoints, watchpoints, and real-time variable monitoring without halting peripheral operation - documented in RL78/D1A User's Manual Section 3.2.4 and E2 Emulator User's Manual R01UL0077E.
