Product details
Overview
R5F212A8SNFA#X6 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2A Group, featuring 64 KB flash ROM, 3 KB RAM, and operation at up to 20 MHz (VCC = 3.0–5.5 V). It integrates a 10-bit 12-channel ADC, dual 8-bit DACs, three UARTs, I²C/SSU, hardware LIN, six timer modules (including 16-bit RD with complementary PWM), and real-time clock functionality. It targets embedded control in consumer audio and office equipment.
For engineers reviewing the R5F212A8SNFA#X6 datasheet, R5F212A8SNFA#X6 pinout, R5F212A8SNFA#X6 application, or R5F212A8SNFA#X6 equivalent, key selection criteria include its 64-pin LQFP package (PLQP0064GA-A), -20°C to +85°C industrial temperature grade (N version), on-chip debug support, and absence of data flash-distinguishing it from R8C/2B Group variants.
Technical Context
The R5F212A8SNFA#X6 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier for efficient signal processing. Its memory map spans 1 Mbyte, and instruction execution time reaches 50 ns at 20 MHz under 3.0–5.5 V supply.
Peripheral integration includes Timer RD with reset-synchronous and complementary PWM modes for motor control, LIN physical layer support via UART0 and Timer RA, and flexible clock sources: external XIN (up to 20 MHz), high-speed on-chip oscillator (adjustable), and 32 kHz XCIN for RTC. Power management supports wait mode (2.1 µA) and stop mode (0.65 µA) at 3.0 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F212A8SNFP#X6 | Same R8C/2A Group MCU, identical 64 KB ROM/3 KB RAM, but in 64-pin LQFP PLQP0064KB-A (0.5 mm pitch, 10 mm × 10 mm). | Requires PCB redesign due to smaller footprint and tighter pitch; preferred where board space is constrained. | Select when layout density is critical and re-spin supports fine-pitch routing. |
| R5F212B8SNFA#X6 | Adds 2 KB data flash (1 KB × 2 blocks) with 10,000-cycle endurance; otherwise identical peripherals, package, and speed. | Suitable for applications requiring field-updatable calibration data or parameter storage without external EEPROM. | Choose only if persistent non-volatile data logging or firmware parameter retention is required. |
Compared with R5F212A8SNFA#X6, R5F212A8SNFP#X6 offers identical functionality in a denser package, while R5F212B8SNFA#X6 adds data flash for configuration storage-neither is pin-compatible nor drop-in; all require matching PCB layout and firmware validation.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F212A8SNFA#X6?
The R5F212A8SNFA#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. Its minimum instruction execution time is 50 ns under the 20 MHz/3.0–5.5 V condition. These ratings are validated per Renesas' REJ03B0182-0210 specification document.
Does the R5F212A8SNFA#X6 include data flash memory?
No, the R5F212A8SNFA#X6 belongs to the R8C/2A Group and contains only program flash ROM (64 KB) with 1,000 erase/write cycles. Data flash (1 KB × 2 blocks) is exclusive to the R8C/2B Group, such as R5F212B8SNFA#X6. This distinction is confirmed in Tables 1.1–1.4 and Figure 1.1 of the official datasheet.
Which package type does the R5F212A8SNFA#X6 use, and what are its mechanical dimensions?
The R5F212A8SNFA#X6 uses the PLQP0064GA-A 64-pin LQFP package: 0.8 mm pin pitch, 14 mm × 14 mm body size, and standard 1.4 mm height. This differs from the PLQP0064KB-A variant used in FP-suffixed parts, which has 0.5 mm pitch and 10 mm × 10 mm footprint.
What peripheral functions are supported by the P2 port on the R5F212A8SNFA#X6?
P2_0 through P2_7 on the R5F212A8SNFA#X6 serve as TRDIOx pins for Timer RD, enabling complementary PWM output, three-phase waveform generation, and dead-time insertion. They are not general-purpose I/O by default and require peripheral function enablement via register configuration.
Is the R5F212A8SNFA#X6 qualified for automotive applications?
No, the R5F212A8SNFA#X6 is an N-version device rated for -20°C to +85°C and classified as "Standard" quality grade per Renesas documentation. It is intended for consumer and industrial applications-not automotive, medical, or safety-critical systems, which require D- or Y-versions with extended temperature and qualification testing.
