Product details
Overview
R5F212B7SDFP#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 over −40°C to +85°C. It integrates a 16×16-bit multiplier, 12-channel 10-bit A/D converter, dual 8-bit D/A converters, three UARTs, I²C/SSU, hardware LIN, and six flexible timers (RA–RF) - deployed in industrial control panels requiring deterministic real-time response and field firmware updates.
For engineers reviewing the R5F212B7SDFP#V2 datasheet, R5F212B7SDFP#V2 pinout, R5F212B7SDFP#V2 application, or R5F212B7SDFP#V2 equivalent, key selection criteria include its −40°C to +85°C industrial temperature grade, dual-block data flash for safe firmware swapping, integrated LIN physical layer support via UART0+TimerRA, and 64-pin LQFP (PLQP0064KB-A) package with 55 CMOS I/O pins and 8 high-current drive outputs.
Technical Context
The R5F212B7SDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and minimum instruction execution time of 50 ns at 20 MHz (VCC = 3.0–5.5 V). Its memory architecture separates 48 KB program flash (1,000 erase/write cycles) from two independent 1 KB data flash blocks (10,000 cycles), enabling atomic reprogramming without halting application execution.
Peripheral integration includes Timer RD supporting reset-synchronous and complementary PWM for three-phase motor control, Timer RC/RF with input capture for encoder position sensing, and UART0 combined with Timer RA to implement full hardware LIN 2.0/2.1 protocol handling - all operating under low-power wait mode (2.1 µA at 32 kHz XCIN) or stop mode (0.65 µA).
