Product details
Overview
R5F212A7SNFA#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU with 48 KB flash ROM, 2.5 KB RAM, and operation at up to 20 MHz (VCC = 3.0–5.5 V). It integrates 12-channel 10-bit ADC, dual 8-bit DACs, three UARTs, I²C/SSU, hardware LIN, six timer modules (including 16-bit RD with 3-phase PWM), and operates from -20°C to +85°C in a 64-pin LQFP package. It targets cost-sensitive embedded control in consumer appliances and office equipment.
For engineers reviewing the R5F212A7SNFA#V2 datasheet, R5F212A7SNFA#V2 pinout, R5F212A7SNFA#V2 application, or R5F212A7SNFA#V2 equivalent, key selection criteria include its 64-pin PLQP0064GA-A package, absence of on-chip data flash (R8C/2A Group), real-time clock (Timer RE), low-power stop mode (0.65 µA), and LIN bus support via UART0 + Timer RA.
Technical Context
The R5F212A7SNFA#V2 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 supports 1 Mbyte address space in single-chip mode, with flash programming voltage of 2.7–5.5 V and 100 erase/write cycles.
Peripheral integration includes Timer RD (16-bit ×2, 6-pin complementary PWM), Timer RC (16-bit, 3-pin PWM), and UART0 configured as hardware LIN transceiver using internal baud rate generator and break detection-enabling automotive body electronics communication without external LIN transceiver.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F212A7SNFA#V2?
The R5F212A7SNFA#V2 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 20 MHz/3.0 V conditions, enabling deterministic real-time response in motor control loops.
Does the R5F212A7SNFA#V2 include on-chip data flash memory?
No, the R5F212A7SNFA#V2 belongs to the R8C/2A Group and does not include on-chip data flash. It has 48 KB of program flash ROM only. For data flash capability, consider the R8C/2B Group part R5F212B7SNFA#V2, which provides two 1 KB data flash blocks.
Which package type does the R5F212A7SNFA#V2 use, and what are its dimensions?
The R5F212A7SNFA#V2 uses the PLQP0064GA-A 64-pin LQFP package with 0.8 mm pin pitch and a 14 mm × 14 mm body size. This variant replaces the finer-pitch PLQP0064KB-A (0.5 mm pitch) for easier manual assembly and rework in mid-volume production.
How does the hardware LIN functionality work on the R5F212A7SNFA#V2?
The R5F212A7SNFA#V2 implements hardware LIN using UART0 combined with Timer RA for baud rate generation and break field detection per ISO 9141-2. No external LIN transceiver is required-only a simple level-shifter (e.g., SN65HVDA100) is needed to meet physical layer requirements.
What low-power modes are supported by the R5F212A7SNFA#V2, and what are their typical current draws?
The R5F212A7SNFA#V2 supports wait mode (2.1 µA at 3.0 V with 32 kHz XCIN active) and stop mode (0.65 µA at 3.0 V). Both retain RAM content and allow wake-up via external interrupt or RTC alarm-making them ideal for battery-powered sensor nodes and remote controls.
