Product details
Overview
R5F212DCSDFP#V2 from Renesas Electronics is an 80-pin LQFP 16-bit R8C/Tiny Series MCU with 128 KB flash program memory, 1 KB × 2 on-chip data flash, 7.5 KB RAM, and operating temperature range of −40°C to +85°C (D version). It integrates dual 10-bit A/D converters (20 channels), dual 8-bit D/A converters, six timer modules (including three-phase PWM-capable Timer RD), hardware LIN interface, and UART/SSU/I²C serial interfaces. It targets embedded control in industrial motor drives and appliance power management systems.
For engineers reviewing the R5F212DCSDFP#V2 datasheet, R5F212DCSDFP#V2 pinout, R5F212DCSDFP#V2 application, or R5F212DCSDFP#V2 equivalent, key selection criteria include its −40°C to +85°C industrial-grade temperature rating, dual data flash blocks for EEPROM emulation, 16-bit × 16-bit multiplier with MAC support, low-power stop mode (0.65 µA), and integrated hardware LIN transceiver co-located with UART0 and Timer RA.
Technical Context
The R5F212DCSDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and single-chip 1 Mbyte address space. Its clock system includes XIN (up to 20 MHz), XCIN (32 kHz real-time clock), and programmable high-speed on-chip oscillator with frequency adjustment.
Peripheral integration centers on deterministic real-time control: Timer RD supports reset-synchronous and complementary PWM for three-phase motor drive (6-pin output), while the LIN module uses UART0 and Timer RA for ISO 9141-2/SAE J2602-compliant communication without external transceiver components.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for R5F212DCSDFP#V2?
The R5F212DCSDFP#V2 supports up to 20 MHz external crystal (XIN) 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. Minimum instruction execution time is 50 ns under 20 MHz/3.0 V conditions. The on-chip high-speed oscillator provides adjustable frequency for flexible clock sourcing without external components.
Does R5F212DCSDFP#V2 include hardware support for LIN communication?
Yes, R5F212DCSDFP#V2 integrates dedicated hardware LIN functionality using UART0 and Timer RA to implement ISO 9141-2/SAE J2602 protocol framing, checksum generation, and automatic baud rate detection-eliminating software bit-banging and reducing CPU load during LIN message transmission and reception.
How many A/D and D/A channels does R5F212DCSDFP#V2 provide, and what are their resolutions?
R5F212DCSDFP#V2 features a 10-bit resolution A/D converter with 20 input channels (AN0–AN19) supporting sweep mode and sample-and-hold, plus two independent 8-bit D/A converters (DA0, DA1) with dedicated output pins. Both analog peripherals share the VREF reference voltage input for consistent scaling.
What low-power modes are available on R5F212DCSDFP#V2, and what is the lowest current consumption?
R5F212DCSDFP#V2 offers wait mode (2.1 µA at 3.0 V with 32 kHz XCIN) and stop mode (0.65 µA at 3.0 V). Stop mode disables all clocks except the 32 kHz sub-clock, retaining RAM and register contents while allowing wake-up via external interrupts, key inputs, or RTC alarm-ideal for battery-backed sensor nodes.
Is R5F212DCSDFP#V2 pin-compatible with other members of the R8C/2D Group?
Yes, all R8C/2D Group MCUs-including R5F212DCSDFP#V2-use the identical 80-pin LQFP package (PLQP0080KB-A) and share identical pin assignments and electrical characteristics. Memory size, data flash presence, and temperature grade vary by part number, but PCB layout and peripheral routing remain fully interchangeable.
