Product details
Overview
R5F212BCSNFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU in the R8C/2B Group, featuring 128 KB flash program memory, 2 KB on-chip data flash (1 KB × 2 blocks), and 7.5 KB RAM. It operates at up to 20 MHz (VCC = 3.0–5.5 V), supports 55 CMOS I/O ports with selectable pull-up resistors, and integrates 10-bit A/D (12 channels), dual 8-bit D/A converters, hardware LIN, and six timer modules including three-phase PWM-capable Timer RD. It targets embedded control in consumer appliances requiring low-power operation and mixed-signal integration.
For engineers reviewing the R5F212BCSNFP#V2 datasheet, R5F212BCSNFP#V2 pinout, R5F212BCSNFP#V2 application, or R5F212BCSNFP#V2 equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-A (64-pin LQFP), functional role in real-time motor control and sensor interface systems, and validated alternative options for design continuity.
Technical Context
The R5F212BCSNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier, enabling efficient signal processing and control loop execution. Its clock system includes XIN/XOUT (up to 20 MHz), high-speed/low-speed on-chip oscillators (with frequency adjustment), and 32 kHz XCIN/XCOUT for RTC operation - 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 reset-synchronous and complementary PWM for three-phase motor drives; UART0–2, SSU/I²C (shared), and hardware LIN (using UART0 + Timer RA) enable robust communication; and the 10-bit A/D converter includes sample-and-hold for accurate analog sensing across 12 channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F212BCSDFP#V2 | D-version (-40°C to +85°C operating range); identical memory, peripherals, and pinout | Required for industrial environments with extended temperature cycling or outdoor deployment | Select when ambient operating temperature exceeds 85°C or falls below -20°C; otherwise, N-version suffices. |
| R5F212ACSNFP#V2 | R8C/2A Group variant: no on-chip data flash (128 KB ROM only), same CPU/peripherals | Suitable where nonvolatile parameter storage is handled externally or unnecessary | Choose to reduce cost if firmware updates and runtime parameter retention are not required. |
Compared with R5F212BCSNFP#V2, the D-version offers wider temperature tolerance without changing code or layout, while the R5F212ACSNFP#V2 removes data flash to lower unit cost - both retain identical I/O, timers, and communication interfaces for seamless migration.
