Product details
Overview
R5F212D8SDFP#V2 from Renesas Electronics is an 80-pin LQFP 16-bit R8C/Tiny Series MCU with 64 KB flash program memory, 1 KB × 2 on-chip data flash, 3 KB RAM, and -40°C to +85°C industrial temperature rating. It integrates dual 8-bit timers (RA/RB), four 16-bit timers (RC/RD/RE/RF), 10-bit 20-channel ADC, dual 8-bit DACs, three UARTs, I²C/SSU, hardware LIN, and real-time clock - deployed in motor control subsystems of HVAC controllers and industrial sensor nodes.
For engineers reviewing the R5F212D8SDFP#V2 datasheet, R5F212D8SDFP#V2 pinout, R5F212D8SDFP#V2 application, or R5F212D8SDFP#V2 equivalent, key selection criteria include its D-version extended temperature support, dual data flash blocks for firmware update resilience, 16-bit PWM-capable Timer RD with complementary three-phase output, and integrated LIN physical layer timing via UART0+Timer RA.
Technical Context
The R5F212D8SDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its clock system includes XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz RTC), and adjustable high-speed on-chip oscillator - all feeding a programmable frequency divider (1/2/4/8/16) and supporting wait/stop low-power modes.
Peripheral integration centers on deterministic real-time control: Timer RD delivers reset-synchronous or complementary PWM across six pins for BLDC motor commutation; the 20-channel ADC supports sweep mode with sample-and-hold; and the hardware LIN module offloads protocol timing from CPU via dedicated UART0 and Timer RA resources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F212D8SNFP | N-version (-20°C to +85°C); identical memory, peripherals, and pinout | Suitable for indoor, climate-controlled environments only | Select when operating ambient stays above -20°C and cost sensitivity outweighs industrial temp margin |
| R5F212DASNFP | 96 KB program ROM + same 2 KB data flash; otherwise identical peripheral set and package | Required for larger firmware images with complex UI or protocol stacks | Choose when application firmware exceeds 64 KB or future feature expansion is anticipated |
Compared with R5F212D8SDFP#V2, the N-version alternative sacrifices extended temperature range for lower unit cost, while the 96 KB variant trades flash density for headroom in protocol-rich building automation firmware - neither offers enhanced analog or timer capabilities.
