Product details
Overview
R5F10DGECJFB#56 from Renesas Electronics is a 16-bit RL78/D1A microcontroller in a 48-pin LQFP package, featuring 128 KB flash memory, 8 KB RAM, integrated CAN 2.0B controller, and operating at up to 32 MHz. It supports 10-bit ADC (24 channels), 16-bit timer arrays, and low-power modes down to 0.52 µA in HALT mode - deployed in automotive body control modules requiring real-time CAN communication and sensor interfacing.
For engineers reviewing the R5F10DGECJFB#56 datasheet, R5F10DGECJFB#56 pinout, R5F10DGECJFB#56 application, or R5F10DGECJFB#56 equivalent, key selection criteria include CAN channel count, flash endurance (100k write/erase cycles), on-chip debug interface (FINE), VDD operating range (1.6–5.5 V), and AEC-Q100 qualification status for automotive use cases.
Technical Context
The R5F10DGECJFB#56 implements the RL78 CPU core with 16-bit CISC architecture, supporting 131 instructions and 3-stage pipeline execution. It integrates a dedicated CAN controller compliant with ISO 11898-1:2003, supporting both standard and extended frames, with 32 message objects and programmable acceptance filtering.
On-chip peripherals include a 10-bit ADC with sample-and-hold and hardware-triggered conversion sequencing, a 16-bit multifunction timer array (with input capture, output compare, PWM generation, and dead-time insertion), and a serial array unit supporting UART, CSI, and I²C protocols - all clocked from a configurable system clock derived from on-chip oscillator, external crystal, or PLL.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10DGECDSP#56 | Same core, flash, and peripheral set but in 48-pin SSOP package (10.0 mm × 12.0 mm); no CAN transceiver support on package pins | Preferred for space-constrained PCBs where LQFP thermal performance is not required and board area allows larger footprint | Select when mechanical envelope permits SSOP and thermal dissipation < 0.8 W is sufficient |

FAQ
What is the maximum operating frequency of the R5F10DGECJFB#56?
The R5F10DGECJFB#56 operates at a maximum system clock frequency of 32 MHz, achievable via on-chip PLL multiplication of internal high-speed oscillator (HOCO) or external crystal input. This frequency supports real-time CAN message handling at 1 Mbps with ≤12 µs interrupt latency and enables 1 kHz control loop execution with margin for background tasks.
Does the R5F10DGECJFB#56 include hardware support for CAN FD?
No, the R5F10DGECJFB#56 implements a classic CAN 2.0B controller compliant with ISO 11898-1:2003 and does not support CAN FD features such as flexible data-rate, extended payload (up to 64 bytes), or bit rate switching. Its CAN module supports standard and extended identifier formats, 32 message objects, and programmable acceptance filtering - sufficient for legacy automotive and industrial CAN networks.
Is the R5F10DGECJFB#56 qualified to AEC-Q100 standards?
Yes, the R5F10DGECJFB#56 is AEC-Q100 qualified for Grade 2 (−40°C to +105°C ambient temperature) and meets automotive reliability requirements including HTOL, ESD, and latch-up testing. This qualification is documented in Renesas' official RL78/D1A product brief and supported by certified test reports available upon request for automotive design-in.
What debug interface does the R5F10DGECJFB#56 support?
The R5F10DGECJFB#56 supports Renesas' FINE (Fast In-Circuit Emulator) debug interface, a single-wire, high-speed on-chip debug solution compatible with E2 studio and CS+ IDEs. It enables non-intrusive breakpoints, real-time variable watch, flash programming, and traceless execution profiling - all without requiring additional JTAG/SWD pins or external debug probes beyond the standard 5-pin debug header.
How much EEPROM-equivalent functionality does the R5F10DGECJFB#56 provide?
The R5F10DGECJFB#56 does not include true EEPROM but provides 1 KB of data flash memory (within the 128 KB main flash) with dedicated erase/write control and wear-leveling support via Renesas' Data Flash Library. This emulates EEPROM behavior with 100,000 write/erase cycles and retains data for 10 years at 85°C - used for calibration storage, configuration parameters, and event logging in automotive and industrial applications.
