Product details
Overview
R5F10CGBJFB#V2 from Renesas Electronics is a 16-bit RL78/D1A microcontroller in a 48-pin LQFP package, featuring 32 KB flash memory, 2.5 KB RAM, and integrated 10-bit ADC, UART, I²C, and timer peripherals. It operates at up to 32 MHz with low-power SNOOZE mode and supports automotive-grade temperature range (−40°C to +105°C) for body electronics control applications.
For engineers reviewing the R5F10CGBJFB#V2 datasheet, R5F10CGBJFB#V2 pinout, R5F10CGBJFB#V2 application, or R5F10CGBJFB#V2 equivalent, key selection criteria include its 48-pin LQFP footprint, 32 KB on-chip flash with EEPROM emulation, 10-bit 12-channel ADC, CAN-free peripheral set, and compliance with AEC-Q100 Grade 2 for under-hood automotive use.
Technical Context
The R5F10CGBJFB#V2 implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions and 3-stage pipeline execution. It integrates a 15-channel event link controller (ELC) for hardware-triggered peripheral chaining and a 16-bit multifunction timer array unit (TAU) with complementary PWM outputs.
Its power management includes three low-power modes (HALT, STOP, and SNOOZE), with wake-up from STOP mode in ≤3.5 µs via external interrupt or RTC alarm. The device uses Renesas' proprietary "Simplified Flash" technology enabling 100K write/erase cycles and data retention >20 years at 85°C.

FAQ
What is the maximum operating frequency of the R5F10CGBJFB#V2?
The R5F10CGBJFB#V2 operates at a maximum CPU clock frequency of 32 MHz, achieved via on-chip PLL with external crystal (1–20 MHz) or internal high-speed oscillator (32 MHz). This frequency is fully supported across the entire −40°C to +105°C temperature range and 1.6 V to 5.5 V supply voltage range, enabling deterministic real-time response in automotive control loops.
Does the R5F10CGBJFB#V2 include a CAN interface?
No, the R5F10CGBJFB#V2 does not include a CAN controller or associated CAN physical layer support pins. It belongs to the "no CAN" variant group of the RL78/D1A family, as confirmed in Section 1.4.1 of the RL78/D1A Hardware User's Manual (Rev.1.10). For CAN-enabled alternatives, consider the R5F10DGBJFB#V2, which shares the same 48-pin LQFP package but adds a single CAN 2.0B module.
What is the flash endurance and data retention specification for the R5F10CGBJFB#V2?
The R5F10CGBJFB#V2 features 32 KB of on-chip flash memory rated for 100,000 write/erase cycles and guaranteed data retention of more than 20 years at +85°C ambient temperature. Its EEPROM emulation function leverages dedicated flash sectors with built-in wear-leveling firmware, enabling byte-level writes and true EEPROM-like behavior without external components.
Is the R5F10CGBJFB#V2 qualified for automotive applications?
Yes, the R5F10CGBJFB#V2 is AEC-Q100 Grade 2 qualified (−40°C to +105°C), making it suitable for automotive body electronics applications such as door modules, seat controls, and HVAC actuators. Its qualification includes stress testing for temperature cycling, humidity bias, and ESD per JESD22 standards, and it meets Renesas' "High Quality" grade requirements for transportation equipment.
What debug interface does the R5F10CGBJFB#V2 support?
The R5F10CGBJFB#V2 supports full-featured on-chip debug (OCD) via a single-wire Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards. This enables real-time program execution control, hardware breakpoints, memory/register access, and trace data capture using standard Renesas E2 studio or third-party IDEs with SWD probe support.
