It integrates a 10-bit A/D converter (12 channels), dual 8-bit D/A converters, 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 and office equipment.

For engineers reviewing the R5F212A7SNLG#U0 datasheet, R5F212A7SNLG#U0 pinout, R5F212A7SNLG#U0 application, or R5F212A7SNLG#U0 equivalent, key selection criteria include its 64-pin FLGA package (PTLG0064JA-A), -20°C to +85°C industrial temperature grade (N version), low-power stop mode (0.65 µA), and on-chip debug support - all critical for space-constrained, cost-sensitive MCU designs requiring mixed-signal integration and LIN bus capability.

Technical Context

The R5F212A7SNLG#U0 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 memory architecture separates 48 KB program flash (1,000 erase/write cycles) from SRAM, with no on-chip data flash - distinguishing it from R8C/2B Group variants like R5F212B7SNLG.

Peripheral integration includes Timer RD (16-bit ×2, 6-pin complementary PWM), UART0–2 with LIN support via UART0+Timer RA, and a shared I²C/SSU interface. Clock sources comprise XIN (up to 20 MHz), high-/low-speed on-chip oscillators, and 32 kHz XCIN for RTC - all configurable via system control registers without external components.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212A7SNLG#U0?

The R5F212A7SNLG#U0 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 specified in the R8C/2A Group datasheet (REJ03B0182-0210, Rev.2.10), and the R5F212A7SNLG#U0 must be operated within these validated ranges to ensure timing compliance and reliability.

Does the R5F212A7SNLG#U0 include on-chip data flash memory?

No, the R5F212A7SNLG#U0 belongs to the R8C/2A Group and contains only 48 KB of program flash ROM with 1,000 erase/write cycles. It does not integrate data flash. In contrast, R8C/2B Group members like R5F212B7SNLG#U0 include 1 KB × 2 on-chip data flash. This distinction is explicitly defined in Tables 1.1–1.4 and Product Lists 1.5–1.6 of the R8C/2A/2B Group documentation.

What package type and pin count does the R5F212A7SNLG#U0 use?

The R5F212A7SNLG#U0 uses a 64-pin FLGA package with code PTLG0064JA-A (0.65 mm pitch, 6 mm × 6 mm body). This is confirmed in Table 1.5 (Product List for R8C/2A Group) and Figure 1.1 of the R8C/2A Group datasheet. The "LG" suffix in the part number directly maps to this FLGA variant, distinguishing it from LQFP options (FP/FA).

Which communication interfaces are supported by the R5F212A7SNLG#U0?

The R5F212A7SNLG#U0 supports UART0–2 (three independent channels), I²C bus (shared with SSU interface), clock-synchronous serial I/O (SSU), and hardware LIN via UART0 + Timer RA. It does not include SPI or CAN interfaces. All serial peripheral functions are documented in Table 1.2 and verified in the block diagram (Figure 1.3) of the R8C/2A Group datasheet.

What is the operating ambient temperature range for the R5F212A7SNLG#U0?

The R5F212A7SNLG#U0 is an "N version" device rated for -20°C to +85°C operating ambient temperature, as indicated by the "N" in its part number and confirmed in Table 1.2 and Figure 1.1 of the R8C/2A Group datasheet. This qualifies it for standard industrial and consumer applications but excludes extended-temperature automotive (D version: -40°C to +85°C) or high-temp (Y version) use cases.
