Renesas R5F212C8SNFP#V2

Overview

R5F212C8SNFP#V2 from Renesas Electronics is an 80-pin LQFP 16-bit R8C/Tiny Series MCU with 64 KB flash ROM, 3 KB RAM, 20-channel 10-bit A/D converter, dual 8-bit D/A outputs, and integrated LIN module for automotive body electronics control. It operates at up to 20 MHz (3.0–5.5 V), supports wait/stop low-power modes (0.65 µA in stop), and integrates six timers including PWM-capable Timer RD for motor control.

For engineers reviewing the R5F212C8SNFP#V2 datasheet, R5F212C8SNFP#V2 pinout, R5F212C8SNFP#V2 application, or R5F212C8SNFP#V2 equivalent, key selection criteria include its -20°C to +85°C N-version temperature grade, on-chip debug capability, 16×16-bit hardware multiplier, and dedicated LIN physical layer support via UART0 and Timer RA - critical for cost-sensitive automotive sub-systems requiring functional safety-aware firmware updates.

Technical Context

The R5F212C8SNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and single-cycle multiply-accumulate (16×16+32→32). Its clock system includes three independent oscillation circuits: XIN (20 MHz max), XCIN (32 kHz real-time clock), and high-speed/low-speed on-chip oscillators with frequency adjustment.

Peripheral integration centers on deterministic timing control: Timer RD provides reset-synchronous and complementary PWM for three-phase motor drives; Timer RC and RF support input capture and output compare for encoder interfacing; and the LIN module uses UART0 with Timer RA for baud rate generation and sync pulse handling per ISO 9141-2 and SAE J2602.

FAQ

What is the maximum operating frequency and supply voltage range for R5F212C8SNFP#V2?

R5F212C8SNFP#V2 operates at up to 20 MHz when supplied with 3.0–5.5 V, 10 MHz at 2.7–5.5 V, and 5 MHz at 2.2–5.5 V. The minimum instruction execution time is 50 ns under 20 MHz/3.0 V conditions. These ratings are validated across the full -20°C to +85°C ambient temperature range specified for the N-version device.

Does R5F212C8SNFP#V2 include on-chip data flash memory?

No, R5F212C8SNFP#V2 belongs to the R8C/2C Group and contains only program flash ROM (64 KB) with 1,000 write/erase cycles. It does not include the 2×1 KB data flash blocks found in the R8C/2D Group (e.g., R5F212D8SNFP). Data retention and update flexibility require external EEPROM or FRAM when using R5F212C8SNFP#V2.

How many PWM output channels does R5F212C8SNFP#V2 support, and which timer provides them?

R5F212C8SNFP#V2 supports up to 6 simultaneous PWM outputs via Timer RD, configured in PWM mode. Timer RD also offers reset-synchronous PWM (for three-phase inverters), complementary PWM (with dead-time insertion), and PWM3 mode (2 fixed-period outputs). Timer RC provides 3 additional PWM pins, and Timer RB supports programmable waveform generation.

What LIN protocol versions are supported by the hardware LIN module in R5F212C8SNFP#V2?

The hardware LIN module in R5F212C8SNFP#V2 implements ISO 9141-2 and SAE J2602 physical layer compliance using UART0 and Timer RA. It handles automatic sync field detection, break field generation, checksum calculation (classic and enhanced), and identifier filtering - all without CPU intervention during frame transmission/reception.

Is R5F212C8SNFP#V2 pin-compatible with other members of the R8C/2C Group?

Yes, all R8C/2C Group devices including R5F212C8SNFP#V2 share identical 80-pin LQFP (PLQP0080KB-A) packaging and pin assignments. Firmware and hardware designs can be scaled across memory variants (R5F212C7SNFP, R5F212C8SNFP#V2, R5F212CASNP, etc.) without PCB revision, provided peripheral usage remains within the target device's resource limits.
