Overview
R5F212AASNFA#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU with 96 KB flash ROM, 7 KB RAM, and integrated peripherals including 12-channel 10-bit ADC, dual 8-bit DACs, three UARTs, I²C/SSU, hardware LIN, and six timer modules (RA–RF) supporting PWM, input capture, and real-time clock functions - deployed in consumer appliance control and industrial HMI systems.
For engineers reviewing the R5F212AASNFA#V2 datasheet, R5F212AASNFA#V2 pinout, R5F212AASNFA#V2 application, or R5F212AASNFA#V2 equivalent, key selection criteria include its 64-pin LQFP package (PLQP0064GA-A), -20°C to +85°C operating range (N version), low-power stop mode (0.65 µA), and on-chip debug capability for firmware development and field calibration.
Technical Context
The R5F212AASNFA#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier, enabling efficient signal processing in resource-constrained embedded applications. It supports single-chip operation across a 1 Mbyte address space and executes instructions in as little as 50 ns at 20 MHz.
Its peripheral set includes Timer RD (16-bit × 2, 6-pin complementary PWM), Timer RC (16-bit, 3-pin PWM), and a dedicated LIN module using UART0 and Timer RA - all mapped to configurable I/O ports with selectable pull-up resistors and 8 high-current drive pins for direct LED or relay interfacing.
