FAQ
What is the maximum operating frequency and supply voltage range for the R5F213J4CNNP?
The R5F213J4CNNP 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 minimum. This dual-voltage capability allows deployment in both battery-powered (1.8 V) and line-powered (5 V) systems without level-shifting circuitry. The internal high-speed on-chip oscillator provides factory-trimmed stability across voltage and temperature.
Does the R5F213J4CNNP support hardware LIN communication, and how is it implemented?
Yes, the R5F213J4CNNP includes a dedicated hardware LIN module compliant with LIN 2.0/2.1 standards. It combines UART0 for serial framing and Timer RA for precise baud rate generation and synchronization. No external transceiver is required for basic slave-node operation, though an external LIN transceiver (e.g., TJA1020) is needed for bus physical layer compliance in automotive environments.
How does the background operation (BGO) function work in the R5F213J4CNNP data flash?
The R5F213J4CNNP supports background operation (BGO) on its 4 KB data flash (1 KB × 4 blocks), allowing erase or program operations to proceed concurrently with code execution from other memory regions. This enables seamless firmware updates, parameter logging, or calibration storage without halting real-time tasks - critical for uninterrupted operation in audio or motor control applications.
What low-power modes are available on the R5F213J4CNNP, and what are their typical current draws?
The R5F213J4CNNP offers wait mode (3.5 µA @ 3.0 V, 32 kHz XCIN clock active) and stop mode (2.0 µA @ 3.0 V, all clocks halted except optional low-speed oscillator for watchdog). These modes are entered via software control and support fast wake-up (< 10 µs from wait mode) using interrupts from key inputs, timers, or serial activity - ideal for battery-backed user interfaces.
Can the R5F213J4CNNP generate complementary PWM waveforms for three-phase motor control?
Yes, Timer RD in the R5F213J4CNNP supports complementary PWM mode with automatic dead-time insertion, generating synchronized three-phase waveforms across six output pins (TRDIOA0/B0/C0/D0/A1/B1). This enables direct drive of gate drivers for BLDC or stepper motor inverters without external logic, reducing system complexity and improving timing precision versus software-timed solutions.
