Renesas R5F212K2SDFP#V2

Overview

R5F212K2SDFP#V2 from Renesas Electronics is an 8 KB flash-based 16-bit R8C/Tiny Series MCU with D-version industrial temperature range (−40°C to +85°C), 1 KB RAM, 10-bit 9-channel A/D converter, and integrated LIN hardware module. It features a 32-pin LQFP package, low-power stop mode (0.7 µA), and supports UART0/UART2 serial interfaces for embedded control in appliance and industrial applications.

For engineers reviewing the R5F212K2SDFP#V2 datasheet, R5F212K2SDFP#V2 pinout, R5F212K2SDFP#V2 application, or R5F212K2SDFP#V2 equivalent, key selection criteria include its −40°C to +85°C operating range, on-chip LIN compliance (using timer RA and UART0), 16-bit × 16-bit multiplier, 25 CMOS I/O ports with selectable pull-up resistors, and 32-pin PLQP0032GB-A package compatibility.

Technical Context

The R5F212K2SDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and single-chip operation across 1 Mbyte address space. Its instruction execution time reaches 50 ns at 20 MHz (VCC = 3.0–5.5 V), enabled by a dedicated 16-bit × 16-bit → 32-bit multiplier and multiply-accumulate unit.

It integrates four independent timers (RA–RD), including 16-bit Timer RD with complementary PWM and three-phase waveform generation, plus hardware LIN protocol support via UART0 and timer RA. The device lacks on-chip data flash-distinguishing it from the R8C/2L Group-and relies solely on 8 KB program flash with 1,000-cycle endurance.

FAQ

What is the maximum operating frequency and supply voltage range for R5F212K2SDFP#V2?

R5F212K2SDFP#V2 operates up to 20 MHz at VCC = 3.0–5.5 V, 10 MHz at VCC = 2.7–5.5 V, and 5 MHz at VCC = 2.2–5.5 V (with A/D converter functional only above 2.7 V). These ratings are validated for the D-version −40°C to +85°C temperature range and define the electrical envelope for reliable timing and analog performance.

Does R5F212K2SDFP#V2 include on-chip data flash memory?

No, R5F212K2SDFP#V2 does not include on-chip data flash. It contains only 8 KB of program flash memory with 1,000 erase/write cycles. Data flash functionality is exclusive to the R8C/2L Group (e.g., R5F212L2SDFP), which provides two 1 KB data flash blocks rated for 10,000 cycles.

Which pins on R5F212K2SDFP#V2 support hardware LIN communication?

R5F212K2SDFP#V2 implements hardware LIN using UART0 and timer RA. Specifically, UART0 provides the serial data path, while timer RA supplies the baud rate timing and synchronization signals required for LIN 2.0/2.1 frame generation and reception-eliminating software UART overhead.

What are the low-power consumption values for R5F212K2SDFP#V2 in stop and wait modes?

In stop mode at VCC = 3.0 V, R5F212K2SDFP#V2 draws 0.7 µA; in wait mode with low-speed on-chip oscillator active, it consumes 23 µA at the same voltage. These values reflect measured typical current under specified conditions and enable multi-year battery life in intermittent-sensing applications.

Is R5F212K2SDFP#V2 pin-compatible with other members of the R8C/2K Group?

Yes, R5F212K2SDFP#V2 shares the identical 32-pin PLQP0032GB-A package and pin assignment with all R8C/2K Group variants-including R5F212K4SDFP and R5F212K2SNFP-ensuring mechanical and electrical compatibility across memory and temperature grade variants.
