Renesas R5F212A8SNFA#V2

Overview

R5F212A8SNFA#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2A Group, featuring 64 KB flash ROM, 3 KB RAM, and operation at up to 20 MHz (V_CC = 3.0–5.5 V). It integrates a 10-bit 12-channel ADC, dual 8-bit DACs, three UARTs, I²C/SSU, hardware LIN, and six timer modules including PWM-capable Timer RD and real-time clock Timer RE. It targets embedded control in consumer appliances requiring low-power operation and mixed-signal integration.

For engineers reviewing the R5F212A8SNFA#V2 datasheet, R5F212A8SNFA#V2 pinout, R5F212A8SNFA#V2 application, or R5F212A8SNFA#V2 equivalent, key selection criteria include its 64-pin LQFP package (PLQP0064GA-A), -20°C to +85°C industrial temperature grade (N version), on-chip debug support, and absence of data flash-distinguishing it from R8C/2B Group variants.

Technical Context

The R5F212A8SNFA#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, and 32 kHz XCIN/XCOUT for RTC operation, with selectable frequency division (1/2/4/8/16) and oscillation stop detection.

Peripheral integration centers on deterministic real-time control: Timer RD provides six-PWM output with complementary, reset-synchronous, and triangular/sawtooth modulation modes; LIN functionality is implemented via UART0 and Timer RA; and the 12-channel ADC supports sample-and-hold for noise-immune analog acquisition in motor or sensor interfaces.

FAQ

What is the maximum operating frequency and supply voltage range for R5F212A8SNFA#V2?

R5F212A8SNFA#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 highest-speed condition. The device supports multiple low-power modes-including wait and stop-with sub-microamp current draw, making it suitable for battery-operated systems where dynamic clock scaling is required. All timing specifications are validated per Renesas' REJ03B0182-0210 datasheet Rev.2.10.

Does R5F212A8SNFA#V2 include on-chip data flash memory?

No, R5F212A8SNFA#V2 belongs to the R8C/2A Group and contains only program flash ROM (64 KB) with 1,000 write/erase cycles. It does not integrate data flash. In contrast, R8C/2B Group devices such as R5F212B8SNFA#V2 include 1 KB × 2 data flash blocks rated for 10,000 cycles. This distinction is explicitly defined in Tables 1.1–1.4 and Product Lists 1.5–1.6 of the official Renesas documentation for the R8C/2A and R8C/2B Groups.

What peripheral interfaces are supported by R5F212A8SNFA#V2?

R5F212A8SNFA#V2 supports three UART modules (UART0–UART2), one shared I²C bus/SSU interface, hardware LIN using UART0 and Timer RA, a 10-bit 12-channel ADC with sample-and-hold, two 8-bit DACs, and six timer units (RA–RF) with advanced PWM and capture/compare capabilities. It lacks CAN, USB, Ethernet, or SDIO interfaces. Serial peripheral selection is fixed per pin assignment-e.g., SDA/SCS shares P3_4-and requires careful multiplexing planning during schematic design.

What is the package type and pin count of R5F212A8SNFA#V2?

R5F212A8SNFA#V2 uses a 64-pin LQFP package designated PLQP0064GA-A, with 0.8 mm pin pitch and 14 mm × 14 mm body size. This differs from the PLQP0064KB-A variant (0.5 mm pitch, 10 mm × 10 mm) used in R5F212A8SNFP#V2. Pin assignments-including TRD motor control signals on P2, analog inputs on P0, and oscillator terminals on P4-are fully documented in Figures 1.4 and 1.5 and Tables 1.7–1.8 of the Renesas R8C/2A Group datasheet.

Is R5F212A8SNFA#V2 qualified for automotive applications?

No, R5F212A8SNFA#V2 is an N-version device rated for -20°C to +85°C ambient operation and classified as "Standard" quality grade per Renesas' quality policy-intended for consumer and industrial applications such as home appliances and office equipment. It is not qualified for automotive use (which requires D-version -40°C to +85°C rating and "High Quality" grade certification), nor for safety-critical or life-support systems ("Specific" grade). Automotive qualification would require explicit validation and part numbering per Renesas' automotive product line.
