Product details
Overview
R5F212K2SNFP#X6 from Renesas Electronics is an 8 KB flash, 1 KB RAM R8C/Tiny Series 16-bit MCU in 32-pin LQFP (PLQP0032GB-A), operating at up to 20 MHz with 10-bit A/D converter (9 channels), dual UART, hardware LIN, and four timer modules (RA–RD) for motor control and embedded timing. It targets cost-sensitive industrial and consumer appliance control.
For engineers reviewing the R5F212K2SNFP#X6 datasheet, R5F212K2SNFP#X6 pinout, R5F212K2SNFP#X6 application, or R5F212K2SNFP#X6 equivalent, key selection criteria include its -20°C to +85°C N-version temperature grade, low-power stop mode (0.7 µA), on-chip debug support, and absence of data flash-distinguishing it from R8C/2L Group variants.
Technical Context
The R5F212K2SNFP#X6 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and 7-level interrupt priority. Its memory map spans 1 Mbyte, with fixed interrupt vectors at 0FFDCh–0FFFFh and SFRs mapped to 00000h–002FFh.
It integrates two clock sources (XIN oscillator + high-/low-speed on-chip oscillators), voltage detection (power-on reset + VDET3), and peripheral control via dedicated SFRs-including timer RD's complementary PWM for three-phase motor drive and LIN protocol handling via UART0 and timer RA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | R8C/Tiny 16-bit core with 89 instructions, 50 ns min. instruction time at 20 MHz |
| Memory | 8 KB flash program ROM, 1 KB RAM - sufficient for compact firmware with real-time ISR handling |
| A/D Converter | 10-bit resolution × 9 channels with sample-and-hold - supports analog sensor interfacing without external ADC |

Pinout & Package
Package: 32-pin LQFP (PLQP0032GB-A, 7 mm × 7 mm, 0.8 mm pitch), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC/AVCC (Pin 7) | Supply & analog reference rail | Single 2.2–5.5 V supply powers digital logic and A/D converter; AVCC requires local decoupling |
| VSS/AVSS (Pin 5) | Digital & analog ground | Common return path; separation of AVSS improves A/D noise immunity |
| XIN/P4_6 (Pin 6) | External clock input | Accepts crystal (1–20 MHz) or external clock signal; enables precise timing for UART/LIN |
| RESET (Pin 3) | Active-low reset input | Hardware reset assertion halts CPU, clears registers, and restarts from vector table address 0FFDCh |
| P1_4/TXD0 (Pin 21) | UART0 transmit output | Drives RS-232/RS-485 level-shifter or LIN transceiver; supports baud rates up to 1 Mbps at 20 MHz |
| P2_0/TRDIOA0/TRDCLK (Pin 16) | Timer RD channel A0 I/O + clock input | Configurable as PWM output or external clock source for synchronized three-phase motor control |
Key Features
| Feature | Design Value |
|---|---|
| On-chip debug interface | Enables real-time firmware debugging and flash rewrite without external emulator - reduces development cycle time |
| Hardware LIN controller | Offloads LIN protocol framing, checksum, and synchronization from CPU - ensures deterministic bus timing |
| Complementary PWM mode | Generates matched high-side/low-side gate drive signals with programmable dead-time - prevents shoot-through in inverter stages |
| Voltage detection circuit | Monitors VCC and triggers reset if drops below VDET3 threshold - protects against brown-out corruption of flash or RAM |
| Selectable pull-up resistors | Software-configurable on 25 CMOS I/O pins - eliminates external BOM components for button/key inputs |

FAQ
What is the maximum operating frequency and supply voltage range for R5F212K2SNFP#X6?
R5F212K2SNFP#X6 operates at up to 20 MHz when supplied with 3.0–5.5 V, 10 MHz at 2.7–5.5 V, and 5 MHz at 2.2–5.5 V (with A/D converter functional only above 2.7 V). These graded frequency/voltage ratings allow flexible power design across battery- and line-powered applications while maintaining timing integrity.
Does R5F212K2SNFP#X6 include data flash memory?
No, R5F212K2SNFP#X6 contains 8 KB of program flash ROM and 1 KB of RAM but no dedicated data flash. Data flash is present only in the R8C/2L Group (e.g., R5F212L2SNFP). For non-volatile parameter storage, external EEPROM or emulated flash in program ROM must be used with R5F212K2SNFP#X6.
Which timer modules in R5F212K2SNFP#X6 support complementary PWM output?
Only Timer RD in R5F212K2SNFP#X6 supports complementary PWM mode, generating synchronized high-side/low-side outputs on six pins (TRDIOA0–TRDIOD1) with configurable dead-time insertion - essential for driving three-phase inverter bridges without external logic.
What debug capabilities does R5F212K2SNFP#X6 provide?
R5F212K2SNFP#X6 features on-chip debug support via dedicated debug pins, enabling full-cycle firmware debugging, register inspection, breakpoint setting, and in-system flash programming without external JTAG emulators - accelerating bring-up and validation of motor control or communication firmware.
Is R5F212K2SNFP#X6 pin-compatible with other R8C/2K Group MCUs?
Yes, all R8C/2K Group devices in the PLQP0032GB-A package - including R5F212K2SNFP#X6, R5F212K4SNFP, and R5F212K2SDFP - share identical pin assignments, electrical characteristics, and peripheral register maps, allowing drop-in replacement based on memory or temperature grade requirements.
