Renesas R5F213J5CNNP#U0

Overview

R5F213J5CNNP from Renesas is a 16-bit R8C CPU core MCU with 24 KB flash ROM, 2 KB data flash (4 × 1 KB blocks), and 2 KB RAM in a 36-pin HWQFN package. It delivers 50 ns min instruction execution at 20 MHz (VCC = 2.7–5.5 V), integrates 10-bit × 10-channel ADC, dual 8-bit DACs, LIN hardware module, and real-time clock (Timer RE) for embedded control in consumer appliances.

For engineers reviewing the R5F213J5CNNP datasheet, R5F213J5CNNP pinout, R5F213J5CNNP application, or R5F213J5CNNP equivalent, key selection considerations include its 36-pin PWQN0036KA-B package, background operation (BGO) support for data flash, integrated LIN transceiver capability via Timer RA + UART0, and low-power stop mode (2.0 µA @ 3.0 V).

Technical Context

The R5F213J5CNNP implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte (00000h–FFFFFh), with program ROM starting at 0A000h, data flash at 03000h–03FFFh, and RAM at 00400h–00BFFh.

It features four independent clock sources: XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz), high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator - all selectable via system clock control registers CM0/CM1. Oscillation stop detection and voltage monitoring (VDD/VLVD) provide robust reset and safety functions.

FAQ

What is the maximum operating frequency and voltage range for the R5F213J5CNNP?

The R5F213J5CNNP operates at up to 20 MHz when supplied with 2.7–5.5 V, achieving a minimum instruction execution time of 50 ns. At lower voltage (1.8–5.5 V), it supports 5 MHz operation with 200 ns min instruction time. These ranges are validated per Renesas specification REJ03B0302-0100 Rev.1.00, ensuring reliable timing across consumer-grade power rails.

Does the R5F213J5CNNP support in-system programming and data retention during reprogramming?

Yes, the R5F213J5CNNP supports background operation (BGO) for its 1 KB × 4 data flash blocks, enabling concurrent CPU execution and flash programming/erasure. Data flash endurance is rated at 10,000 write/erase cycles, and program ROM endurance is 1,000 cycles. This allows safe firmware updates and parameter logging without halting system operation - a confirmed capability documented in Section 1.1 and Table 1.2 of the R5F213J5CNNP datasheet.

How many analog-to-digital converter channels does the R5F213J5CNNP include, and what is their resolution?

The R5F213J5CNNP integrates a 10-bit successive-approximation ADC with 10 input channels (AN0–AN6, AN8–AN11). It includes sample-and-hold functionality and supports sweep mode for automatic channel scanning. This ADC is explicitly specified in Table 1.2 and Figure 1.2 of the R5F213J5CNNP datasheet, and is used for sensor interfacing in applications like temperature monitoring and motor current sensing.

Can the R5F213J5CNNP generate complementary PWM waveforms for three-phase motor control?

Yes, the R5F213J5CNNP's Timer RD supports complementary PWM mode, generating synchronized three-phase waveforms across six output pins (TRDIOA0/TRDIOA1/TRDIOB0/TRDIOB1/TRDIOC0/TRDIOC1) with triangular wave modulation. This capability is defined in Table 1.1 under "Timer RD" and enables direct driving of gate drivers in BLDC or PMSM motor inverters without external logic.

What debug and development support is available for the R5F213J5CNNP?

The R5F213J5CNNP includes on-chip debug functionality and on-board flash rewrite capability, allowing full in-circuit debugging via standard JTAG or FINE interfaces. Renesas provides the HEW (High-performance Embedded Workshop) IDE and Flash Development Toolkit specifically validated for the R8C/3JC Group, enabling breakpoint setting, register inspection, and live memory modification - all confirmed in Section 1.1.2 and Table 1.2 of the R5F213J5CNNP datasheet.
