Product details
Overview
R5F212A7SNFA#V0 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2A Group, featuring 48 KB flash ROM, 2.5 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 PWM-capable RD and RC), and operates across –20°C to +85°C. It targets embedded control in consumer appliances and office equipment.
For engineers reviewing the R5F212A7SNFA#V0 datasheet, R5F212A7SNFA#V0 pinout, R5F212A7SNFA#V0 application, or R5F212A7SNFA#V0 equivalent, key selection considerations include its 64-pin LQFP (PLQP0064GA-A) package, 2.2–5.5 V supply range, on-chip voltage detection, low-power stop mode (0.65 µA), and absence of on-chip data flash-distinguishing it from R8C/2B Group variants.
Technical Context
The R5F212A7SNFA#V0 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier for efficient signal processing. Its clock system includes XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz real-time clock), and high-/low-speed on-chip oscillators with frequency adjustment.
Peripheral integration centers on deterministic timing control: Timer RD supports reset-synchronous and complementary PWM for motor drive, Timer RC provides 3-pin PWM output, and the LIN module uses UART0 and Timer RA for ISO 9141-2/SAE J2602 compliance. All 55 CMOS I/O pins support selectable pull-up resistors and eight are high-current drive capable.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F212A7SNFP#V0 | Same R8C/2A Group, identical specs, but in 64-pin LQFP PLQP0064KB-A (0.5 mm pitch, 10 mm × 10 mm). | Requires PCB redesign due to smaller footprint and finer pitch - preferred where board space is constrained. | Select when layout density is critical and rework capability supports 0.5 mm pitch assembly. |
| R5F212B7SNFA#V0 | Same package and memory size, but adds 2 × 1 KB data flash (10,000-cycle endurance) - absent in R5F212A7SNFA#V0. | Suitable for field-upgradable firmware or parameter storage; not required for static configuration in fixed-function appliances. | Choose only if runtime reprogramming of non-volatile settings or bootloader updates are needed. |
Compared with R5F212A7SNFA#V0, R5F212A7SNFP#V0 offers identical functionality in a denser package requiring tighter layout tolerances, while R5F212B7SNFA#V0 adds data flash for dynamic configuration - neither is pin-compatible nor drop-in; both demand firmware and hardware validation.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F212A7SNFA#V0?
The R5F212A7SNFA#V0 operates at up to 20 MHz when supplied at 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 highest-speed condition. This graded frequency/voltage relationship allows flexible power-performance trade-offs in battery-powered or wide-input-range designs without derating.
Does the R5F212A7SNFA#V0 include on-chip data flash memory?
No, the R5F212A7SNFA#V0 belongs to the R8C/2A Group and contains only program flash ROM (48 KB) with 100 write/erase cycles. It does not include dedicated data flash. For data logging or field-upgradable parameters, external EEPROM or an R8C/2B Group part like R5F212B7SNFA#V0 (with 2 × 1 KB data flash) must be selected.
Which communication interfaces are supported by the R5F212A7SNFA#V0?
The R5F212A7SNFA#V0 supports three UART channels (UART0–UART2), one I²C bus (shared with SSU), one clock-synchronous serial interface (SSU), and a hardware LIN module implemented using UART0 and Timer RA. No CAN, USB, or Ethernet interfaces are integrated - external transceivers or companion ICs are required for those protocols.
What are the low-power modes available on the R5F212A7SNFA#V0 and their typical current draw?
The R5F212A7SNFA#V0 supports wait mode (2.1 µA at 3.0 V with 32 kHz XCIN clock) and stop mode (0.65 µA at 3.0 V). Standard operating mode draws 12 mA at 5.0 V/20 MHz. These modes are controlled via software and retain RAM content and register states - enabling rapid wake-up for responsive user interfaces or periodic sensor polling.
Is the R5F212A7SNFA#V0 pin-compatible with any R8C/2B Group devices?
No, the R5F212A7SNFA#V0 is not pin-compatible with R8C/2B Group devices such as R5F212B7SNFA#V0, despite sharing the same PLQP0064GA-A package. Differences in internal flash architecture and data flash circuitry affect power sequencing and reset behavior - PCB layout and firmware initialization must be validated separately for each group.
