Renesas R5F212CCSDFP#V2

Overview

R5F212CCSDFP#V2 from Renesas Electronics is an 80-pin LQFP 128 KB Flash MCU in the R8C/2C Group, featuring an R8C/Tiny Series CPU core with 16×16→32-bit multiplier, 10-bit ×20-channel A/D converter, dual 8-bit D/A outputs, and hardware LIN interface (via Timer RA + UART0). It operates from 2.2–5.5 V at up to 20 MHz and targets industrial control and appliance motor management.

For engineers reviewing the R5F212CCSDFP#V2 datasheet, R5F212CCSDFP#V2 pinout, R5F212CCSDFP#V2 application, or R5F212CCSDFP#V2 equivalent, key selection criteria include its -40°C to +85°C operating range (D version), on-chip debug support, 0.65 µA stop-mode current, and integrated PWM-capable timers RD/RC for precise motor phase control.

Technical Context

The R5F212CCSDFP#V2 implements a single-chip R8C/Tiny CPU core with 89 fundamental instructions and 1 Mbyte address space, executing instructions in as little as 50 ns at 20 MHz. Its clock system includes three independent oscillation circuits: XIN (up to 20 MHz), XCIN (32 kHz real-time clock), and high-/low-speed on-chip oscillators with frequency adjustment.

Peripheral integration centers on six timer modules (RA–RF), including Timer RD with complementary PWM mode for three-phase motor drive, and dedicated hardware LIN transceiver logic tied to UART0 and Timer RA. The device lacks on-chip data flash-distinguishing it from R8C/2D Group variants-and relies on external EEPROM or program ROM for nonvolatile parameter storage.

FAQ

What is the maximum operating frequency of the R5F212CCSDFP#V2?

The R5F212CCSDFP#V2 supports a maximum operating frequency of 20 MHz when powered at 3.0–5.5 V using the XIN clock source. At lower supply voltages (2.2–2.7 V), the maximum frequency reduces to 5 MHz to ensure stable operation and meet timing margins across process and temperature variations.

Does the R5F212CCSDFP#V2 include on-chip data flash memory?

No, the R5F212CCSDFP#V2 belongs to the R8C/2C Group and contains only program flash memory (128 KB). It does not include dedicated data flash blocks. For on-chip data storage, users must rely on program flash emulation or external nonvolatile memory such as EEPROM or FRAM.

What peripheral functions are supported by the P2_0 pin on the R5F212CCSDFP#V2?

The P2_0 pin on the R5F212CCSDFP#V2 serves dual roles: TRDIOA0 (Timer RD Phase-A output) and TRDCLK (external clock input for Timer RD). This enables both PWM waveform generation for motor phase-A and synchronization with external timing sources, supporting advanced commutation schemes like encoder-based rotor position tracking.

How many analog input channels does the R5F212CCSDFP#V2 support, and what is their resolution?

The R5F212CCSDFP#V2 integrates a 10-bit successive-approximation A/D converter with 20 configurable analog input channels (AN0–AN19). Each channel supports sample-and-hold operation and sweep mode for sequential conversion, delivering 1024 discrete levels across the selected voltage reference range.

What is the purpose of the MODE pin on the R5F212CCSDFP#V2, and how should it be connected?

The MODE pin on the R5F212CCSDFP#V2 selects the boot mode at reset. It must be externally pulled high to VCC via a resistor (typically 10 kΩ) to enter normal program execution mode. Leaving MODE floating or pulling low may cause unpredictable startup behavior or entry into test/debug modes not intended for production use.
