Overview
R5F212G5SDFP from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller with 24 KB Flash ROM, 1 KB RAM, and integrated peripherals including UART0/UART2, LIN module, four timers (RA/RB/RE/RF), voltage detection, comparator, and real-time clock functionality - deployed in electric power meters and industrial control systems requiring low-power operation and EMI resilience.
For engineers reviewing the R5F212G5SDFP datasheet, R5F212G5SDFP pinout, R5F212G5SDFP application, or R5F212G5SDFP equivalent, this page delivers verified technical context, package mapping, validated pin functions, key timing and power specifications, and two confirmed alternative MCUs for design continuity in metering and appliance control applications.
Technical Context
The R5F212G5SDFP implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability. It operates at up to 8 MHz (VCC = 2.7–5.5 V) or 4 MHz (VCC = 2.2–5.5 V), supporting single-chip mode with 1 Mbyte address space.
Its peripheral set includes UART0 and UART2 with clock-synchronous serial I/O, dedicated hardware LIN interface (using timer RA and UART0), 8-bit timers RA/RB/RE, 16-bit timer RF with capture/compare, two comparators sharing voltage monitor inputs, and three voltage detection circuits with programmable thresholds.
