Product details
Overview
R5F213N7TNBX#W5 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 48 KB flash program ROM, 4 KB RAM, and 4 KB data flash (1 KB × 4 blocks) supporting background operation (BGO). It operates at up to 20 MHz (VCC = 2.7–5.5 V), integrates a 10-bit 12-channel ADC with sample-and-hold, electrostatic capacitive touch detection (5 channels + 3 system CH), and real-time clock (Timer RE). It targets embedded control in consumer audio and appliance interfaces.
For engineers reviewing the R5F213N7TNBX#W5 datasheet, R5F213N7TNBX#W5 pinout, R5F213N7TNBX#W5 application, or R5F213N7TNBX#W5 equivalent, key selection criteria include its 48-pin WPP package (SWBG0048LA-A), low-power stop mode (2.0 µA @ 3.0 V), integrated sensor control unit for touch UI, and dual UART + I²C/SSU serial interfaces for system connectivity.
Technical Context
The R5F213N7TNBX#W5 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte (00000h–FFFFFh), with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash at 03000h–03FFFh.
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 CM0/CM1 registers. Power management includes wait mode (4.0 µA @ 32 kHz) and stop mode (2.0 µA), with voltage detection (VDD = 1.8–5.5 V) and power-on reset.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F213N7TNBX#W5?
The R5F213N7TNBX#W5 supports a maximum operating frequency of 20 MHz when powered at VCC = 2.7–5.5 V. At lower supply voltages (1.8–5.5 V), it operates up to 5 MHz. This dual-frequency capability allows designers to optimize performance versus power consumption based on system requirements and battery conditions. The R5F213N7TNBX#W5 maintains full peripheral functionality across this entire voltage range.
Does the R5F213N7TNBX#W5 support capacitive touch sensing without external components?
Yes, the R5F213N7TNBX#W5 integrates a dedicated Sensor Control Unit (SCU) that enables electrostatic capacitive touch detection on five dedicated pins (CH0–CH4) with three system control pins (CHxA–CHxC). No external RC networks or dedicated touch controller ICs are required. The SCU handles baseline tracking, noise rejection, and threshold comparison in hardware, making the R5F213N7TNBX#W5 ideal for touch-button and slider implementations in consumer appliances.
How much data flash memory does the R5F213N7TNBX#W5 include, and what is its endurance?
The R5F213N7TNBX#W5 includes 4 KB of data flash memory organized as four 1-KB blocks, each supporting background operation (BGO) for concurrent read/write operations. Its programming and erasure endurance is rated at 10,000 cycles - sufficient for storing calibration data, user preferences, or event logs in long-lifecycle embedded systems. This capability is confirmed in the R01DS0047EJ0100 datasheet Section 1.1.2.
What low-power modes are available on the R5F213N7TNBX#W5, and what are their typical current draws?
The R5F213N7TNBX#W5 offers wait mode (4.0 µA @ 3.0 V with 32 kHz XCIN clock) and stop mode (2.0 µA @ 3.0 V), both retaining RAM content and allowing wake-up via external interrupt or key input. These modes are enabled via system clock control registers (CM0/CM1) and support rapid resumption (< 10 µs wake-up time). The R5F213N7TNBX#W5 achieves these figures without external circuitry, making it suitable for battery-powered remote controls and smart home sensors.
Is the R5F213N7TNBX#W5 pin-compatible with other members of the R8C/3NT Group?
Yes, the R5F213N7TNBX#W5 shares the identical 48-pin WPP package (SWBG0048LA-A) and pin assignment with all R8C/3NT Group variants including R5F213N8TNBX#W5, R5F213NATNBX#W5, and R5F213NCTNBX#W5. All share the same peripheral mapping, I/O register layout, and electrical characteristics - enabling hardware reuse across product tiers.
