Renesas R5F212BASNFA#V2

Overview

R5F212BASNFA#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU in the R8C/2B Group, featuring 96 KB flash program memory, 1 KB × 2 on-chip data flash, 7 KB RAM, and operation up to 20 MHz at 3.0–5.5 V. It integrates 12-channel 10-bit ADC, dual 8-bit DACs, three UARTs, I²C/SSU, hardware LIN, six timer modules (including 16-bit RD with 3-phase PWM), and operates from −20°C to +85°C in a 64-pin LQFP package (PLQP0064GA-A). It targets cost-sensitive embedded control in consumer appliances and office equipment.

For engineers reviewing the R5F212BASNFA#V2 datasheet, R5F212BASNFA#V2 pinout, R5F212BASNFA#V2 application, or R5F212BASNFA#V2 equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral capabilities, real-world use cases, and two rigorously cross-checked alternative parts - all grounded in Renesas' official R8C/2B Group specification document REJ03B0182-0210.

Technical Context

The R5F212BASNFA#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier for efficient signal processing. 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 support.

Peripheral integration centers on deterministic real-time control: Timer RD provides reset-synchronous and complementary 3-phase PWM (6-pin output) for motor drive; LIN module leverages UART0 and Timer RA for ISO 9141-2 compliance; and the 12-channel ADC supports sample-and-hold for simultaneous multi-sensor acquisition in appliance UI or power management subsystems.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212BASNFA#V2?

The R5F212BASNFA#V2 operates at up to 20 MHz when supplied at 3.0–5.5 V, 10 MHz at 2.7–5.5 V, and 5 MHz at 2.2–5.5 V. Its minimum instruction execution time is 50 ns under the 20 MHz/3.0–5.5 V condition. These ratings are defined in Renesas document REJ03B0182-0210 Section 1.1.2 and apply specifically to the R5F212BASNFA#V2 variant in its N-version temperature grade (−20°C to +85°C).

Does the R5F212BASNFA#V2 include on-chip debug capability?

Yes, the R5F212BASNFA#V2 includes on-chip debug functionality as specified in Renesas REJ03B0182-0210 Table 1.4. This enables real-time firmware debugging, breakpoint setting, and memory inspection without requiring external emulators - critical for rapid development of appliance control algorithms and motor drive tuning.

How many PWM output pins does the R5F212BASNFA#V2 support, and what timer generates them?

The R5F212BASNFA#V2 supports up to 6 dedicated PWM output pins via Timer RD, which is a 16-bit timer with 4 capture/compare registers. Timer RD supports reset-synchronous PWM, complementary PWM, and PWM3 modes - enabling full 3-phase motor control with hardware-generated dead time, as confirmed in Section 1.1.2 of REJ03B0182-0210.

What is the endurance rating of the on-chip data flash in the R5F212BASNFA#V2?

The on-chip data flash in the R5F212BASNFA#V2 is rated for 10,000 erase/write cycles, distinct from the 1,000-cycle endurance of its program ROM. This higher endurance is explicitly stated in Table 1.4 of Renesas REJ03B0182-0210 and makes the R5F212BASNFA#V2 suitable for frequent parameter updates such as calibration coefficients or usage counters.

Which package type and pin pitch does the R5F212BASNFA#V2 use?

The R5F212BASNFA#V2 uses the PLQP0064GA-A package: a 64-pin LQFP with 0.8 mm pin pitch and 14 mm × 14 mm body size. This is confirmed in Table 1.6 (Product List for R8C/2B Group) and Figure 1.2 of Renesas REJ03B0182-0210, where "FA" denotes this specific package variant.
