Renesas R5F212A7SDFP#V2

Overview

R5F212A7SDFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU with 48 KB flash ROM, 2.5 KB RAM, and -40°C to +85°C industrial temperature rating. It integrates 12-channel 10-bit ADC, dual 8-bit DACs, six timer modules (including three-phase PWM-capable Timer RD), LIN hardware interface, and UART/SSU/I²C serial interfaces. It targets embedded control in automotive body electronics and industrial motor drives requiring robust EMI immunity and low-power operation.

For engineers reviewing the R5F212A7SDFP#V2 datasheet, R5F212A7SDFP#V2 pinout, R5F212A7SDFP#V2 application, or R5F212A7SDFP#V2 equivalent, key selection criteria include its D-version extended temperature range, on-chip LIN transceiver support via UART0+Timer RA, 64-pin LQFP (PLQP0064KB-A) package with 0.5 mm pitch, and absence of on-chip data flash-distinguishing it from R8C/2B Group variants.

Technical Context

The R5F212A7SDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier for efficient signal processing. Its clock system includes XIN/XOUT (up to 20 MHz), high-speed/low-speed on-chip oscillators, and 32 kHz XCIN/XCOUT for RTC, with selectable frequency dividers (1/2/4/8/16) and oscillation stop detection.

Peripheral integration centers on deterministic real-time control: Timer RD provides reset-synchronous and complementary three-phase PWM (6-pin output) for BLDC motor commutation; Timer RC supports input capture and dual PWM outputs; and the LIN module uses dedicated hardware logic tied to UART0 and Timer RA for ISO 9141-2/SAE J2602 compliance without CPU overhead.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212A7SDFP#V2?

The R5F212A7SDFP#V2 supports up to 20 MHz operation at VCC = 3.0–5.5 V, 10 MHz at 2.7–5.5 V, and 5 MHz at 2.2–5.5 V. Its minimum instruction execution time is 50 ns under 20 MHz/3.0 V conditions. This graded frequency-voltage specification allows flexible power/performance trade-offs in battery-powered or wide-input industrial supplies.

Does the R5F212A7SDFP#V2 include on-chip data flash memory?

No, the R5F212A7SDFP#V2 belongs to the R8C/2A Group and does not integrate data flash. It contains only program flash ROM (48 KB) with 1,000 write/erase cycles. For data logging or field-upgradable parameters, consider the R8C/2B Group variant R5F212B7SDFP#V2, which includes 2 KB of data flash rated for 10,000 cycles.

How is the hardware LIN interface implemented on the R5F212A7SDFP#V2?

The R5F212A7SDFP#V2 implements LIN 2.0/SAE J2602 via dedicated hardware combining UART0 and Timer RA. UART0 handles byte-level framing and checksum, while Timer RA generates precise baud rate timing and manages wake-up pulse detection - offloading >90% of LIN protocol processing from the CPU core.

What package type and pin count does the R5F212A7SDFP#V2 use?

The R5F212A7SDFP#V2 uses a 64-pin LQFP package with code PLQP0064KB-A: 0.5 mm pin pitch, 10 mm × 10 mm body, and exposed pad for thermal dissipation. This package is distinct from the larger PLQP0064GA-A (0.8 mm pitch) and FLGA variants, and is optimized for high-density automotive PCB layouts.

What are the key low-power modes supported by the R5F212A7SDFP#V2?

The R5F212A7SDFP#V2 supports wait mode (2.1 µA @ 3 V, 32 kHz RTC active) and stop mode (0.65 µA @ 3 V). In stop mode, the 32.768 kHz XCIN oscillator continues running Timer RE for real-time clockkeeping, enabling precise wake-up intervals without external components - critical for battery-operated sensor nodes.
