Renesas R5F212D7SNFP#V2

Overview

R5F212D7SNFP from Renesas Electronics is an 80-pin LQFP 16-bit R8C/Tiny Series MCU with 48 KB flash program memory, 1 KB × 2 on-chip data flash, 2.5 KB RAM, and operation over −20°C to +85°C. It integrates dual 10-bit A/D converters (20 channels), dual 8-bit D/A converters, hardware LIN interface, and six timer modules including three-phase PWM-capable Timer RD - used in motor control subsystems of industrial appliances and HVAC actuators.

For engineers reviewing the R5F212D7SNFP datasheet, R5F212D7SNFP pinout, R5F212D7SNFP application, or R5F212D7SNFP equivalent, key selection criteria include its −20°C to +85°C N-version temperature grade, 1 KB × 2 data flash endurance (10,000 erase/write cycles), 80-pin PLQP0080KB-A package with 0.5 mm pitch, and support for real-time clock (Timer RE) and LIN 2.0-compliant communication via UART0 + Timer RA.

Technical Context

The R5F212D7SNFP implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its single-chip mode provides 1 Mbyte address space and executes instructions in as little as 50 ns at 20 MHz/3.0–5.5 V.

It features three independent clock sources: XIN oscillator (20 MHz max), high-speed on-chip oscillator (frequency-adjustable), and 32 kHz XCIN crystal circuit. Low-power modes include wait (2.1 µA @ 3.0 V, f(XCIN)=32 kHz) and stop (0.65 µA @ 3.0 V), with voltage detection (VDD = 2.2–5.5 V) and power-on reset.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212D7SNFP?

The R5F212D7SNFP supports a maximum XIN clock frequency of 20 MHz 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 absolute maximum supply voltage is 6.0 V, and operation below 2.2 V is not guaranteed. The R5F212D7SNFP must be operated within these ranges to ensure correct flash programming, A/D conversion accuracy, and timer timing integrity.

Does the R5F212D7SNFP support hardware LIN communication, and how is it implemented?

Yes, the R5F212D7SNFP implements a hardware LIN 2.0 module using UART0 and Timer RA. This dedicated function handles LIN frame formatting, checksum calculation, and synchronization without CPU intervention. The R5F212D7SNFP's LIN module supports auto-baud detection, sleep/wake-up frames, and error recovery - meeting ISO 17987-4 compliance when configured per Renesas application notes.

How many A/D and D/A channels does the R5F212D7SNFP provide, and what are their resolutions?

The R5F212D7SNFP integrates a 10-bit A/D converter with 20 input channels (AN0–AN19) and two independent 8-bit D/A converters (DA0 and DA1). The A/D converter supports sample-and-hold and hardware sweep mode for sequential conversions. Both D/A outputs are buffered and can drive typical 10 kΩ loads - confirmed in the R5F212D7SNFP electrical characteristics table (Rev. 2.10, p. 28).

What low-power modes are available on the R5F212D7SNFP, and what are their typical current draws?

The R5F212D7SNFP offers wait mode (2.1 µA @ 3.0 V, f(XCIN) = 32 kHz) and stop mode (0.65 µA @ 3.0 V), in addition to standard active operation (12 mA @ 5.0 V, 20 MHz). These modes disable clocks to unused peripherals while retaining RAM content and register states. The R5F212D7SNFP achieves these values using internal oscillators and optimized power gating - verified in the "Current Consumption" section of the datasheet (Table 1.4).

Is the R5F212D7SNFP pin-compatible with other members of the R8C/2D Group, such as R5F212D8SNFP?

Yes, all R8C/2D Group MCUs in the PLQP0080KB-A package - including R5F212D7SNFP and R5F212D8SNFP - share identical pinouts, electrical characteristics, and peripheral mappings. Firmware and hardware designs are interchangeable at the board level; only flash capacity differs (48 KB vs. 64 KB). This allows seamless scalability within the same PCB layout.
