FAQ

What is the maximum operating frequency and supply voltage range for the R5F213J6CNNP?

The R5F213J6CNNP operates at up to 20 MHz when supplied with 2.7–5.5 V, and supports reduced-frequency operation down to 5 MHz at 1.8 V. This dual-voltage capability allows deployment in both standard 3.3 V and legacy 5 V systems while maintaining real-time performance across varying power conditions. The R5F213J6CNNP includes internal voltage detection to ensure safe reset behavior during brownout events.

Does the R5F213J6CNNP support hardware LIN communication, and how is it implemented?

Yes, the R5F213J6CNNP integrates a hardware LIN module compliant with LIN 2.1/2.2 standards, implemented using Timer RA for baud rate generation and UART0 for data framing. This eliminates external transceiver requirements in slave-node applications such as automotive door modules or HVAC actuators. The R5F213J6CNNP's LIN functionality is fully register-configurable and supports automatic sync field detection and checksum validation without CPU intervention.

How does the background operation (BGO) feature work in the R5F213J6CNNP data flash?

The R5F213J6CNNP supports background operation (BGO) on its 4 KB data flash (1 KB × 4 blocks), allowing erase and write operations to proceed asynchronously while the CPU executes application code. This enables live firmware updates, parameter logging, or calibration storage without interrupting real-time control loops. The R5F213J6CNNP uses dedicated status flags and interrupt vectors to signal BGO completion or error conditions, ensuring deterministic response timing.

What low-power modes are available on the R5F213J6CNNP, and what are their typical current draws?

The R5F213J6CNNP offers standard operating, wait, and stop modes. In wait mode with 32 kHz XCIN clock active, typical current is 3.5 µA; in stop mode (all clocks halted except 32 kHz oscillator), it drops to 2.0 µA. These modes are entered via software control and support wake-up via external interrupt, RTC alarm, or A/D conversion completion-making the R5F213J6CNNP suitable for battery-powered remote controls and sensor endpoints requiring multi-year operation.

Can the R5F213J6CNNP's 10-bit ADC be used in sweep mode, and how many channels does it support?

Yes, the R5F213J6CNNP's 10-bit ADC supports sweep mode, automatically sequencing conversions across up to 10 analog input channels (AN0–AN6, AN8–AN11) without CPU polling. Each conversion result is stored in dedicated AD0–AD7 registers, and sweep completion triggers an interrupt. This capability simplifies multi-sensor monitoring in applications like environmental sensing or appliance safety checks, where the R5F213J6CNNP must concurrently manage timing-critical control tasks.
