FAQ

What is the operating temperature range for the R5F10ELCGFB#X0?

The R5F10ELCGFB#X0 is rated for industrial operation from −40°C to +105°C, as indicated by the 'G' suffix in its part number. This extended temperature capability ensures reliable performance in demanding environments such as factory automation, motor drives, and outdoor metering equipment where ambient conditions exceed commercial-grade limits.

How much flash memory does the R5F10ELCGFB#X0 contain, and is it self-programmable?

The R5F10ELCGFB#X0 contains 32 KB of on-chip code flash memory with secure boot swap and flash shield window functions. It supports self-programming in-application, enabling firmware updates and field calibration without external programming hardware-critical for remote industrial devices requiring secure over-the-air updates.

Does the R5F10ELCGFB#X0 support LIN bus communication?

Yes, the R5F10ELCGFB#X0 supports LIN bus communication via its UART2 peripheral with LINSEL function. It can operate as a LIN master or slave, providing hardware-assisted break detection, sync field handling, and checksum generation-enabling seamless integration into automotive body electronics and industrial sub-networks.

What are the key low-power modes supported by the R5F10ELCGFB#X0?

The R5F10ELCGFB#X0 supports multiple low-power states: Stop mode (0.23 µA RAM retained), Halt mode (0.57 µA with RTC + LVD), and Snooze mode (0.6–0.7 mA for UART/ADC wake-up). These modes are controlled via system control registers and enable rapid wake-up from deep sleep while maintaining real-time clock accuracy and interrupt responsiveness.

Can the R5F10ELCGFB#X0's ADC measure signals below 1.6 V?

No-the R5F10ELCGFB#X0's 12-bit ADC requires a minimum analog input voltage of 1.6 V per the datasheet specification. However, it supports internal voltage reference (1.45 V) and external AVREFP/AVREFM inputs, allowing scaled measurement ranges. For sub-1.6 V signals, external signal conditioning (e.g., PGA or level-shifting amplifier) is required before ADC input.
