It targets embedded control in industrial appliances and low-power consumer devices requiring integrated timing, analog sensing, and serial communication.
For engineers reviewing the R5F212K4SDFP#V2 datasheet, R5F212K4SDFP#V2 pinout, R5F212K4SDFP#V2 application, or R5F212K4SDFP#V2 equivalent, key selection criteria include its D-version temperature grade, absence of on-chip data flash (distinguishing it from R8C/2L), 32-pin PLQP0032GB-A package compatibility, and support for wait/stop modes down to 0.7 µA.
Technical Context
The R5F212K4SDFP#V2 implements the R8C/Tiny Series CPU core with 89 fundamental instructions and single-chip 1 Mbyte address space. Its clock system integrates XIN/XOUT crystal oscillator support plus high-speed and low-speed on-chip oscillators with frequency adjustment and oscillation stop detection.
Peripheral integration includes Timer RA/RB (8-bit), Timer RC (16-bit, 4 capture/compare), Timer RD (16-bit ×2, 4 capture/compare, 6-pin PWM, three-phase waveforms), UART0/UART2, hardware LIN (using Timer RA and UART0), and 10-bit A/D converter with sample-and-hold across nine channels.
Key Specifications

FAQ
What is the maximum operating frequency of the R5F212K4SDFP#V2?
The R5F212K4SDFP#V2 operates at up to 20 MHz when supplied at 3.0–5.5 V, delivering a minimum instruction execution time of 50 ns. At lower voltages (2.7–5.5 V), it supports 10 MHz operation, and at 2.2–5.5 V, it runs at 5 MHz-ensuring flexibility across diverse power architectures while maintaining deterministic real-time response.
Does the R5F212K4SDFP#V2 include on-chip data flash memory?
No, the R5F212K4SDFP#V2 does not include on-chip data flash memory. It belongs to the R8C/2K Group, which provides only program flash (16 KB). Data flash (1 KB × 2 blocks) is exclusive to the R8C/2L Group, such as R5F212L4SDFP#V2. This distinction is critical for applications requiring nonvolatile parameter storage without external EEPROM.
What package type and dimensions does the R5F212K4SDFP#V2 use?
The R5F212K4SDFP#V2 uses a 32-pin LQFP package designated PLQP0032GB-A (formerly 32P6U-A), measuring 7 mm × 7 mm with 0.8 mm lead pitch. This RoHS-compliant package supports standard reflow soldering and is compatible with automated PCB assembly processes used in high-volume industrial manufacturing.
Can the R5F212K4SDFP#V2 support hardware LIN communication?
Yes, the R5F212K4SDFP#V2 integrates a hardware LIN module compliant with LIN 2.0/2.1 standards, implemented using UART0 and Timer RA. This enables direct connection to a LIN transceiver without software bit-banging, reducing CPU load and ensuring precise timing for automotive body electronics and industrial networked sensors.
What are the low-power consumption figures for the R5F212K4SDFP#V2 in stop and wait modes?
In stop mode at 3.0 V, the R5F212K4SDFP#V2 consumes 0.7 µA; in wait mode with low-speed on-chip oscillator active at 3.0 V, it draws 23 µA. These values reflect actual measured current under specified conditions and enable ultra-low-power operation in battery-backed or energy-harvesting applications where duty-cycled wake-up is required.
