Renesas R5F212CCSNFP#V2

Overview

R5F212CCSNFP#V2 from Renesas Electronics is an 80-pin LQFP 128 KB Flash R8C/Tiny Series 16-bit MCU with 7.5 KB RAM, 20-channel 10-bit A/D converter, dual 8-bit D/A outputs, and hardware LIN support-designed for embedded control in consumer and industrial appliances operating from -20°C to +85°C.

For engineers reviewing the R5F212CCSNFP#V2 datasheet, R5F212CCSNFP#V2 pinout, R5F212CCSNFP#V2 application, or R5F212CCSNFP#V2 equivalent, key selection factors include its 128 KB on-chip flash endurance (1,000 cycles), low-power stop mode (0.65 µA), integrated real-time clock (Timer RE), and 80-pin LQFP package with 71 programmable CMOS I/O ports.

Technical Context

The R5F212CCSNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier, enabling efficient signal processing and control loop execution. It supports three clock sources: XIN (up to 20 MHz), XCIN (32 kHz), and high/low-speed on-chip oscillators-with frequency division (1/2/4/8/16) and oscillation stop detection.

Peripheral integration includes six independent timers (RA–RF) with PWM, input capture, and complementary three-phase waveform generation; three UARTs; shared SSU/I²C interface; and LIN physical layer support via Timer RA and UART0-enabling robust serial communication in noisy environments without external transceivers.

FAQ

What is the maximum operating frequency of the R5F212CCSNFP#V2?

The R5F212CCSNFP#V2 supports a maximum operating frequency of 20 MHz when powered at 3.0 V to 5.5 V. At lower voltages (2.7–5.5 V), it operates up to 10 MHz, and at 2.2–5.5 V, up to 5 MHz. These limits are defined by the XIN clock input and ensure stable CPU and peripheral timing across voltage ranges.

Does the R5F212CCSNFP#V2 include on-chip data flash memory?

No, the R5F212CCSNFP#V2 belongs to the R8C/2C Group and contains only program flash (128 KB). It does not include dedicated data flash. For data flash functionality, consider the R8C/2D Group part R5F212DCSNFP, which adds two 1 KB data flash blocks.

What are the key differences between the R5F212CCSNFP#V2 and R5F212CCSDFP?

The R5F212CCSNFP#V2 is rated for -20°C to +85°C (N version), while R5F212CCSDFP is rated for -40°C to +85°C (D version). All electrical specifications, peripherals, and pinout are identical-the difference is solely in temperature qualification and screening.

Can the R5F212CCSNFP#V2 generate three-phase motor control waveforms?

Yes, the R5F212CCSNFP#V2's Timer RD supports reset-synchronous PWM and complementary PWM modes, enabling direct generation of three-phase waveforms on six output pins with configurable dead time-ideal for BLDC or inverter motor control without external gate drivers.

Is on-chip debug supported on the R5F212CCSNFP#V2?

Yes, the R5F212CCSNFP#V2 includes full on-chip debug capability, allowing real-time program download, breakpoint insertion, register inspection, and memory access via a standard debug interface-no external emulator required for development or field firmware updates.
