Renesas R5F212CASDFP#V2

Overview

R5F212CASDFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2C Group, designed for embedded control in cost-sensitive industrial and consumer systems. It features 96 KB flash ROM, 7 KB RAM, 20-channel 10-bit A/D converter, dual 8-bit D/A outputs, and operates from 2.2 V to 5.5 V at up to 20 MHz (50 ns min instruction time). It supports LIN bus via hardware module (timer RA + UART0) and targets appliance motor control.

For engineers reviewing the R5F212CASDFP#V2 datasheet, R5F212CASDFP#V2 pinout, R5F212CASDFP#V2 application, or R5F212CASDFP#V2 equivalent, key selection criteria include its -40°C to +85°C operating range (D version), 80-pin LQFP package with 71 CMOS I/Os (8 high-current), integrated real-time clock (timer RE), and low-power stop mode (0.65 µA @ 3.0 V).

Technical Context

The R5F212CASDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier plus MAC unit. Its clock system includes three independent oscillation circuits: XIN (20 MHz max), XCIN (32 kHz RTC), and on-chip high-/low-speed oscillators with frequency adjustment.

Peripheral integration centers on six timer units (RA–RF) supporting PWM generation (including 3-phase complementary PWM on timer RD), input capture, and pulse width/period measurement. Serial connectivity comprises three UARTs, one I²C/SSU shared interface, and hardware LIN protocol support-enabling robust communication in noisy environments without software overhead.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for R5F212CASDFP#V2?

R5F212CASDFP#V2 supports 20 MHz operation at VCC = 3.0 V to 5.5 V, 10 MHz at 2.7 V to 5.5 V, and 5 MHz at 2.2 V to 5.5 V. Minimum instruction execution time is 50 ns under the 20 MHz condition. These ratings are validated for the D-version temperature range (-40°C to +85°C), and R5F212CASDFP#V2 must not be operated outside these voltage/frequency combinations.

Does R5F212CASDFP#V2 include on-chip data flash memory?

No, R5F212CASDFP#V2 belongs to the R8C/2C Group and contains only program flash memory (96 KB). It does not include the 2 KB data flash (1 KB × 2 blocks) found in the R8C/2D Group variants like R5F212DASNFP. All non-volatile data storage for R5F212CASDFP#V2 must be implemented in program flash or external memory.

Which timer units in R5F212CASDFP#V2 support complementary PWM output for 3-phase motor control?

Timer RD in R5F212CASDFP#V2 supports complementary PWM mode, generating three-phase waveforms across six output pins (TRDIOA0–TRDIOC1) with triangular wave modulation. This capability enables direct gate-drive signal generation for inverter bridges without external logic, and R5F212CASDFP#V2's timer RD is fully functional in the D-version temperature grade.

Can R5F212CASDFP#V2 operate as a LIN bus master or slave device?

Yes, R5F212CASDFP#V2 integrates a hardware LIN module using timer RA and UART0, supporting both master and slave roles per LIN 2.0/2.1 specifications. The module handles break detection, sync field, and checksum calculation in hardware, reducing CPU load and ensuring timing accuracy - a core feature confirmed for R5F212CASDFP#V2 in the R8C/2C Group documentation.

What are the I/O voltage tolerance and drive strength specifications for R5F212CASDFP#V2 ports?

R5F212CASDFP#V2 features 71 CMOS I/O ports with software-selectable pull-up resistors and 8 high-current drive ports capable of sourcing/sinking ≥20 mA per pin. All I/Os are tolerant to VCC (2.2–5.5 V) and support mixed-voltage interfacing when configured as inputs. Input-only pins (P4_6, P4_7) and analog pins (AN0–AN19, DA0, DA1) follow separate electrical specifications defined in the R8C/2C Group datasheet.
