Product details
Overview
R5F212B7SDFA#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2B Group, featuring 48 KB flash program memory, 1 KB × 2 on-chip data flash, 2.5 KB RAM, and operation across –40°C to +85°C. It integrates a 16×16-bit multiplier, 10-bit A/D converter (12 channels), dual 8-bit D/A converters, three UARTs, I²C/SSU, hardware LIN, and six timer modules including PWM-capable Timer RD and real-time clock Timer RE - deployed in industrial control panels requiring deterministic timing and mixed-signal interfacing.
For engineers reviewing the R5F212B7SDFA#V2 datasheet, R5F212B7SDFA#V2 pinout, R5F212B7SDFA#V2 application, or R5F212B7SDFA#V2 equivalent, key selection criteria include its D-grade temperature rating, dual data flash blocks for EEPROM emulation, low-power stop mode (0.65 µA), and 64-pin LQFP package with 0.8 mm pitch (PLQP0064GA-A).
Technical Context
The R5F212B7SDFA#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and single-cycle multiply-accumulate capability (16×16→32 + 32→32). Its clock system includes XIN/XOUT (up to 20 MHz), high-speed/low-speed on-chip oscillators, and 32 kHz XCIN/XCOUT for RTC - all supported by oscillation stop detection and programmable frequency dividers (1/2/4/8/16).
Peripheral integration centers on deterministic real-time control: Timer RD provides complementary PWM for three-phase motor drive (6-pin output, sawtooth/triangular modulation), while Timer RC and RF support input capture and output compare for encoder interface and pulse measurement. The LIN module uses UART0 and Timer RA for ISO 9141-2/SAE J2602-compliant communication without software overhead.
