FAQ
What is the maximum operating frequency of the R5F10DPFCJFB#56?
The R5F10DPFCJFB#56 operates at a maximum CPU clock frequency of 32 MHz. This is achieved using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator up to 20 MHz with PLL multiplication. The 32 MHz clock enables real-time execution of control loops and communication stacks while maintaining low power consumption in active mode.
Does the R5F10DPFCJFB#56 support AEC-Q100 qualification?
Yes, the R5F10DPFCJFB#56 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient), making it suitable for automotive body electronics applications. This qualification covers stress testing for reliability, including HTOL, temperature cycling, and ESD. The device's built-in safety features-including RAM parity, clock failure detection, and BIST-support functional safety development aligned with ISO 26262 ASIL-B requirements.
How much data flash does the R5F10DPFCJFB#56 include, and what is its purpose?
The R5F10DPFCJFB#56 includes 4 KB of on-chip data flash memory. This memory is specifically designed for nonvolatile parameter storage and supports EEPROM emulation with built-in wear leveling and error correction. It eliminates the need for external EEPROM in applications such as calibration data retention, usage logging, and configuration storage-reducing BOM cost and board space.
Can the R5F10DPFCJFB#56 operate from a single 3.3 V supply?
Yes, the R5F10DPFCJFB#56 supports single-supply operation from 1.6 V to 5.5 V, including standard 3.3 V rails. Its dual power domain architecture (EVDD0/EVSS0 for digital logic and SMVDD0/SMVSS0 for analog peripherals) ensures stable ADC performance and low-noise operation even when powered from 3.3 V, without requiring additional voltage regulators for analog sections.
Is the R5F10DPFCJFB#56 pin-compatible with other RL78/D1A 100-pin variants?
Yes, the R5F10DPFCJFB#56 shares identical pinout and package (100-pin LQFP) with all other RL78/D1A 100-pin devices, including R5F10DPE, R5F10DPG, R5F10TPJ, R5F10DPJ, R5F10DPK, and R5F10DPL. This enables hardware reuse across variants-differences lie in flash/RAM size, peripheral enablement (e.g., number of CAN channels), and safety feature sets-not in physical layout or electrical pin behavior.
