Product details
Overview
R5F212BCSNFA#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2B Group, featuring 128 KB flash program memory, 1 KB × 2 on-chip data flash, 7.5 KB RAM, and operation at up to 20 MHz (VCC = 3.0–5.5 V). It integrates dual UARTs, LIN hardware module, 12-channel 10-bit A/D converter, two 8-bit D/A converters, and six timer units including three-phase PWM-capable Timer RD - deployed in industrial motor control and appliance power management systems.
For engineers reviewing the R5F212BCSNFA#V2 datasheet, R5F212BCSNFA#V2 pinout, R5F212BCSNFA#V2 application, or R5F212BCSNFA#V2 equivalent, key selection criteria include its 64-pin LQFP package (PLQP0064GA-A), -20°C to +85°C operating range (N version), on-chip data flash endurance (10,000 erase/write cycles), real-time clock (Timer RE), and hardware LIN support tied to UART0 and Timer RA.
Technical Context
The R5F212BCSNFA#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient signal processing. Its clock system includes XIN/XOUT (up to 20 MHz), high-speed/low-speed on-chip oscillators, and 32 kHz XCIN/XCOUT for RTC - all supported by oscillation stop detection and programmable frequency division (1/2/4/8/16).
Peripheral integration centers on deterministic timing control: Timer RD provides reset-synchronous and complementary PWM for three-phase motor drive (6-pin output), while Timer RC and RF deliver input capture and output compare for encoder interfacing. The LIN module uses UART0 and Timer RA for ISO-9141/SAE J2602-compliant communication without CPU overhead.

FAQ
What is the maximum operating frequency and supply voltage range for R5F212BCSNFA#V2?
R5F212BCSNFA#V2 operates at up to 20 MHz when supplied with 3.0–5.5 V. At lower frequencies (10 MHz, 5 MHz), it supports down to 2.7 V and 2.2 V respectively - enabling flexible power design across battery and line-powered applications. The R5F212BCSNFA#V2 datasheet specifies these limits under "Operating Frequency/Supply Voltage" in Table 1.4.
Does R5F212BCSNFA#V2 include on-chip debug capability?
Yes, R5F212BCSNFA#V2 features on-chip debug support via the single-wire background debug mode (BDM), allowing real-time code download, breakpoint setting, and register inspection without halting peripheral operation. This capability is documented in the "Debug functions" section of the R5F212BCSNFA#V2 flash memory specification.
How many PWM output pins does R5F212BCSNFA#V2 support for three-phase motor control?
R5F212BCSNFA#V2 supports six dedicated PWM output pins via Timer RD in complementary PWM mode - configured as UH/UL, VH/VL, WH/WL for full three-phase inverter drive. These pins (TRDIOA0–TRDIOD1) are electrically isolated and support programmable dead-time insertion, as defined in the R5F212BCSNFA#V2 timer functional description.
What is the endurance rating of the data flash in R5F212BCSNFA#V2?
The on-chip data flash in R5F212BCSNFA#V2 is rated for 10,000 erase/write cycles - significantly higher than the 1,000-cycle endurance of its program ROM. This allows frequent updates of calibration tables, user preferences, or firmware staging data without premature wear-out. The R5F212BCSNFA#V2 datasheet confirms this in Table 1.4 under "Flash Memory".
Is R5F212BCSNFA#V2 pin-compatible with other R8C/2B Group MCUs?
Yes, R5F212BCSNFA#V2 shares identical pinout and electrical characteristics with all other R8C/2B Group devices in the PLQP0064GA-A package, including R5F212B7SNFA#V2 and R5F212BASNFA#V2. This enables direct substitution within the same package variant, provided firmware accommodates differences in ROM size and feature enablement.
