Renesas R5F213J6TNNP#W4

Overview

R5F213J6TNNP from Renesas Electronics is a 16-bit R8C/3JT Group microcontroller featuring 32 KB flash program ROM, 2.5 KB RAM, and 4 KB data flash with background operation (BGO). It integrates an R8C CPU core with 16×16-bit multiplier, 10-bit ×12-channel ADC, dual UART/I²C/SSU serial interfaces, LIN hardware module, and electrostatic capacitive touch detection for consumer appliance control. Operating at up to 20 MHz (V_CC = 2.7–5.5 V), it targets low-power embedded systems requiring mixed-signal integration and real-time responsiveness.

For engineers reviewing the R5F213J6TNNP datasheet, R5F213J6TNNP pinout, R5F213J6TNNP application, or R5F213J6TNNP equivalent, key selection criteria include its 40-pin HXQFN package (PXQN0040LA-A), −20°C to +85°C industrial temperature grade, on-chip debug support, and hardware LIN compliance-critical for appliance motor control, sensor interface, and power management subsystems.

Technical Context

The R5F213J6TNNP implements the R8C CPU core with 89 fundamental instructions and supports single-chip mode across a 1 Mbyte address space. Its clock system includes three independent sources: external XIN/XOUT crystal/resonator circuit, high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator-with selectable frequency division (1/2/4/8/16) and oscillation stop detection.

Peripheral integration centers on deterministic real-time control: Timer RC provides 16-bit PWM output on 3 pins and input capture; UART2 supports I²C-bus mode and multiprocessor communication; the Sensor Control Unit enables 22-channel capacitive touch sensing with dedicated CHxA/B/C and SCUTRG trigger inputs; and the DTC (Data Transfer Controller) offers one channel with 22 activation sources for autonomous memory transfers.

FAQ

What is the maximum operating frequency of the R5F213J6TNNP and under what voltage conditions?

The R5F213J6TNNP operates at a maximum frequency of 20 MHz when supplied with V_CC = 2.7 V to 5.5 V. At reduced voltage (1.8 V to 5.5 V), the maximum frequency is 5 MHz. This dual-voltage/frequency specification allows flexible power-performance trade-offs in battery-powered and line-powered applications.

Does the R5F213J6TNNP support in-system programming and debugging?

Yes, the R5F213J6TNNP includes full on-chip debug functionality and supports in-system flash rewriting via its built-in debug interface. This enables firmware updates and real-time debugging without removing the device from the target board, streamlining development and field maintenance for R5F213J6TNNP-based products.

How many analog input channels does the R5F213J6TNNP ADC support, and what is its resolution?

The R5F213J6TNNP integrates a 10-bit successive-approximation ADC with 12 dedicated analog input channels (AN0–AN11). It supports sample-and-hold operation and sweep mode for sequential conversion of multiple channels, delivering consistent 10-bit precision across the full 1.8–5.5 V supply range.

What package type and pin count does the R5F213J6TNNP use?

The R5F213J6TNNP uses a 40-pin HXQFN package designated PXQN0040LA-A. It features a 5 mm × 5 mm body, 0.4 mm pin pitch, and an exposed thermal pad. This compact, surface-mount package supports high-density PCB layouts while maintaining thermal performance for R5F213J6TNNP's mixed-signal operation.

Is hardware LIN bus support integrated into the R5F213J6TNNP?

Yes, the R5F213J6TNNP includes a dedicated hardware LIN module that combines Timer RA and UART0 to implement LIN 2.x physical layer signaling. This eliminates external transceivers for basic LIN node functionality, reducing component count and improving EMI robustness in R5F213J6TNNP-based appliance control modules.
