Overview
R5F212BASDFA#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2B Group, featuring 96 KB flash program memory, 1 KB × 2 on-chip data flash, 7 KB RAM, and operation over −40°C to +85°C. It integrates a 16×16→32-bit hardware multiplier, 12-channel 10-bit A/D converter, dual 8-bit D/A converters, and six timer modules (including three-phase PWM-capable Timer RD). It targets embedded control in industrial sensors and motor-driven consumer appliances.
For engineers reviewing the R5F212BASDFA#V2 datasheet, R5F212BASDFA#V2 pinout, R5F212BASDFA#V2 application, or R5F212BASDFA#V2 equivalent, key selection criteria include its −40°C to +85°C industrial temperature grade, dual on-chip data flash blocks for EEPROM-like wear leveling, LIN bus support via UART0+Timer RA, and 64-pin LQFP package with 0.8 mm pitch (PLQP0064GA-A).
Technical Context
The R5F212BASDFA#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and single-cycle multiply-accumulate capability. Its clock system includes XIN/XOUT (up to 20 MHz), high-speed/low-speed on-chip oscillators, and 32 kHz XCIN/XCOUT for real-time clock operation.
Peripheral integration includes three UARTs, one I²C/SSU shared interface, hardware LIN module, 12-channel 10-bit A/D with sample-and-hold, and Timer RD supporting reset-synchronous and complementary PWM for three-phase motor control - all mapped to a 55-pin CMOS I/O port array with selectable pull-up resistors and eight high-current drive pins.
