Product details
Overview
R5F212AASDFA#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU in the R8C/2A Group, designed for embedded control in cost-sensitive industrial and consumer systems. It features 96 KB flash ROM, 7 KB RAM, 12-channel 10-bit A/D converter, dual 8-bit D/A converters, and operates from 2.2 V to 5.5 V across -40°C to +85°C (D version). It delivers 50 ns minimum instruction execution at 20 MHz and integrates hardware LIN, three UARTs, I²C/SSU, and six advanced timers including complementary PWM for motor control.
For engineers reviewing the R5F212AASDFA#V2 datasheet, R5F212AASDFA#V2 pinout, R5F212AASDFA#V2 application, or R5F212AASDFA#V2 equivalent, key selection considerations include its 64-pin LQFP (PLQP0064GA-A) package with 55 CMOS I/Os, 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 R5F212AASDFA#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier supporting multiply-accumulate operations. Its memory map spans 1 Mbyte, and it executes code directly from flash with no external bus interface.
Peripheral integration includes Timer RD (16-bit × 2, 6-pin complementary PWM), Timer RC (16-bit, 3-pin PWM), UART0–2, I²C/SSU shared on P3_4/P3_5, and a dedicated LIN module using UART0 and Timer RA. Clock sources comprise XIN (up to 20 MHz), high-/low-speed on-chip oscillators, and 32 kHz XCIN for RTC.

FAQ
What is the maximum operating frequency and supply voltage range for R5F212AASDFA#V2?
R5F212AASDFA#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/5.0 V conditions. The device maintains full functionality across its specified -40°C to +85°C industrial temperature range, making R5F212AASDFA#V2 suitable for demanding environmental deployments.
Does R5F212AASDFA#V2 include on-chip data flash memory?
No, R5F212AASDFA#V2 belongs to the R8C/2A Group and contains only program flash ROM (96 KB). It does not integrate data flash - a feature exclusive to the R8C/2B Group (e.g., R5F212BASDFA#V2). For nonvolatile data storage, external EEPROM or FRAM must be used with R5F212AASDFA#V2, or the R8C/2B alternative selected.
Which package type does R5F212AASDFA#V2 use, and what are its key mechanical dimensions?
R5F212AASDFA#V2 uses the PLQP0064GA-A 64-pin LQFP package: 14 mm × 14 mm body size, 0.8 mm pin pitch, and standard JEDEC footprint. This package supports reflow soldering and is compatible with common PCB assembly processes. Its larger pad pitch compared to the PLQP0064KB-A variant simplifies layout routing and improves manufacturing yield in high-volume production.
How many UART interfaces does R5F212AASDFA#V2 support, and are they independently configurable?
R5F212AASDFA#V2 supports three fully independent UART interfaces (UART0, UART1, UART2), each with dedicated TX/RX pins and separate baud rate generators. UART0 is additionally shared with the hardware LIN module. All three UARTs operate simultaneously and can be assigned to different pins via register configuration, enabling concurrent communication with displays, sensors, and host controllers without multiplexing conflicts.
What low-power modes are available on R5F212AASDFA#V2, and what is the typical current draw in stop mode?
R5F212AASDFA#V2 offers wait mode (2.1 µA @ 3.0 V, f(XCIN)=32 kHz) and stop mode (0.65 µA @ 3.0 V). In stop mode, the CPU, flash, and most peripherals halt while retaining RAM content and allowing wake-up via external interrupt or RTC alarm. This ultra-low quiescent current makes R5F212AASDFA#V2 appropriate for battery-powered remote sensors and energy-harvesting nodes requiring multi-year operation.
