FAQ

What is the maximum operating frequency and corresponding performance of the R5F100PKGFB#X0?

The R5F100PKGFB#X0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its high-accuracy on-chip oscillator maintains ±1.0% tolerance across 1.8–5.5 V and −20°C to +85°C, eliminating need for external crystal in many cost-sensitive applications while ensuring deterministic timing for real-time control loops in the R5F100PKGFB#X0.

Does the R5F100PKGFB#X0 support LIN bus communication, and how is it implemented?

Yes, the R5F100PKGFB#X0 supports LIN bus communication through its UART peripherals, which include LIN-specific features such as break detection, sync field handling, and checksum calculation. Two to four UART channels are available, and any can be configured for LIN 2.1/2.2 compliance-enabling direct integration into automotive body control modules without external LIN transceivers in the R5F100PKGFB#X0 design.

What are the power-saving modes available on the R5F100PKGFB#X0, and what functions remain active in each?

The R5F100PKGFB#X0 offers HALT, STOP, and SNOOZE modes. In STOP mode (0.57 μA), only the RTC and LVD remain active; HALT mode halts CPU while preserving RAM and peripheral registers; SNOOZE enables selective peripheral operation (e.g., ADC conversion or UART receive) during low-power sleep. All modes retain full register context and resume instantly upon wake event in the R5F100PKGFB#X0.

How does the data flash memory in the R5F100PKGFB#X0 differ from standard code flash, and what is its endurance?

The R5F100PKGFB#X0 includes dedicated 8 KB data flash memory optimized for frequent read/write operations, supporting background operation (BGO) so program execution continues during rewrites. It guarantees 1,000,000 erase/write cycles at VDD = 1.8–5.5 V-significantly exceeding standard code flash endurance-and includes flash shield window and block protection to prevent unauthorized access in the R5F100PKGFB#X0.

What is the ADC resolution, input channel count, and reference voltage options for the R5F100PKGFB#X0?

The R5F100PKGFB#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference voltages or internal 1.45 V reference (available only in HS mode), and includes an on-chip temperature sensor. The ADC operates across the full 1.6–5.5 V supply range, enabling accurate sensor interfacing in diverse voltage domains within the R5F100PKGFB#X0.
