Product details
Overview
R5F212A7SDFA#U0 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2A Group, designed for embedded control in industrial and consumer systems. It features 48 KB flash ROM, 2.5 KB RAM, 12-channel 10-bit A/D converter, dual 8-bit D/A converters, and operates from -40°C to +85°C. Its integrated LIN module (using Timer RA and UART0), low-power stop mode (0.65 µA), and 64-pin LQFP package support compact motor control and appliance HMI applications.
For engineers reviewing the R5F212A7SDFA#U0 datasheet, R5F212A7SDFA#U0 pinout, R5F212A7SDFA#U0 application, or R5F212A7SDFA#U0 equivalent, key selection criteria include its D-version temperature grade (-40°C to +85°C), absence of on-chip data flash (distinguishing it from R8C/2B Group), 55 CMOS I/O ports with selectable pull-up resistors, and hardware LIN compliance for automotive body electronics integration.
Technical Context
The R5F212A7SDFA#U0 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier for efficient signal processing. It supports single-chip operation across a 1 Mbyte address space and executes instructions in as little as 50 ns at 20 MHz (VCC = 3.0–5.5 V).
Its peripheral set includes six independent timers (RA–RF) with PWM, input capture, and real-time clock (Timer RE) functions; three UARTs; one shared SSU/I²C interface; and a dedicated hardware LIN transceiver layer. Clock sources comprise XIN/XOUT (up to 20 MHz), high-/low-speed on-chip oscillators, and XCIN/XCOUT (32 kHz) for RTC operation.
