Product details
Overview
R5F212AASNFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU with 96 KB flash ROM, 7 KB RAM, and 64-pin LQFP (PLQP0064KB-A) package. It integrates a 16×16-bit multiplier, 12-channel 10-bit A/D converter, 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 - deployed in consumer appliance motor control and sensor interface applications.
For engineers reviewing the R5F212AASNFP#V2 datasheet, R5F212AASNFP#V2 pinout, R5F212AASNFP#V2 application, or R5F212AASNFP#V2 equivalent, key selection criteria include its -20°C to +85°C operating range (N version), low-power stop mode (0.65 µA), on-chip debug support, and absence of data flash (distinguishing it from R8C/2B Group variants).
Technical Context
The R5F212AASNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and single-chip 1 Mbyte address space. Its clock system includes XIN/XOUT (up to 20 MHz), high-/low-speed on-chip oscillators, and 32 kHz XCIN/XCOUT for RTC operation - all supported by oscillation stop detection and selectable frequency dividers (1/2/4/8/16).
Peripheral integration centers on deterministic timing control: Timer RD provides six-PWM output with complementary three-phase modulation, Timer RC offers 4-register 16-bit capture/compare, and UART0 is hardware-linked to Timer RA for LIN bus compliance. All 55 CMOS I/O pins support programmable pull-up resistors and eight are high-current drive capable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | R8C/Tiny 16-bit core with 89 instructions; executes in 50 ns at 20 MHz - enables deterministic real-time response in motor commutation loops. |
| Memory | 96 KB flash ROM + 7 KB RAM; no on-chip data flash - suitable for firmware-only deployments without field data logging. |
| A/D Converter | 10-bit resolution × 12 channels with sample-and-hold - supports simultaneous sampling of multi-sensor inputs in appliance control panels. |
| Timers | Timer RD (16-bit ×2, 6-PWM, complementary three-phase); Timer RC (16-bit, 4 capture/compare registers) - enables brushless DC motor drive with dead-time control. |
| Power Modes | Stop mode current = 0.65 µA at 3.0 V; wait mode = 2.1 µA with 32 kHz RTC active - extends battery life in always-on standby functions. |
| Operating Range | -20°C to +85°C (N version); supply voltage 2.2–5.5 V - certified for standard consumer electronics environments per Renesas quality grade. |
| Package | 64-pin LQFP, PLQP0064KB-A (0.5 mm pitch, 10 mm × 10 mm) - compatible with standard surface-mount reflow profiles and automated optical inspection. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0_0–P0_7 | Analog input / D/A output / digital I/O | AN0–AN7 and DA0/DA1 mapped here - enables direct connection to potentiometers, thermistors, and analog actuators without external signal conditioning. |
| P1_0–P1_7 | General-purpose I/O / LIN transceiver / interrupt input | P1_5/RXD0 and P1_4/TXD0 form dedicated LIN physical layer interface; P1_7/INT1 supports edge-triggered wake-up from stop mode. |
| P2_0–P2_7 | Timer RD I/O / three-phase PWM output | TRDIOA0–TRDIOC1 pins deliver six synchronized PWM outputs - directly drives gate drivers in 3-phase inverter stages. |
| P4_3/P4_4 | 32 kHz crystal oscillator input/output | XCIN/XCOUT pins connect to 32.768 kHz tuning-fork crystal - provides accurate timebase for Timer RE real-time clock with ±20 ppm stability. |

FAQ
What is the maximum operating frequency of the R5F212AASNFP#V2?
The R5F212AASNFP#V2 supports a maximum external crystal frequency of 20 MHz at VCC = 3.0–5.5 V, achieving a minimum instruction execution time of 50 ns. Its on-chip high-speed oscillator is adjustable but rated up to 10 MHz; actual system clock speed depends on selected prescaler and PLL configuration as defined in the clock generation circuit register settings.
Does the R5F212AASNFP#V2 include on-chip data flash memory?
No, the R5F212AASNFP#V2 belongs to the R8C/2A Group and contains no data flash. It has 96 KB of program flash ROM and 7 KB of RAM only. Data flash (1 KB × 2 blocks) is exclusive to R8C/2B Group parts like R5F212BASNFP - confirmed in Tables 1.1–1.4 and Product List Table 1.5 of the official datasheet REJ03B0182-0210.
Which package type does the R5F212AASNFP#V2 use?
The R5F212AASNFP#V2 uses the 64-pin LQFP package with code PLQP0064KB-A (0.5 mm pin pitch, 10 mm × 10 mm body). This matches the "FP" suffix in the part number and is explicitly listed in Table 1.5 (Product List for R8C/2A Group) and Figure 1.1 of the Renesas documentation.
Can the R5F212AASNFP#V2 operate in extended temperature ranges?
The R5F212AASNFP#V2 is an N-version device rated for -20°C to +85°C ambient operation. D-version variants (e.g., R5F212AASDFP) support -40°C to +85°C, and Y-version parts cover -20°C to +105°C - but these require different part numbers and are not interchangeable with R5F212AASNFP#V2 without validation.
What debug capabilities does the R5F212AASNFP#V2 provide?
The R5F212AASNFP#V2 includes full on-chip debug support with flash rewrite functionality, enabling real-time breakpoint setting, register inspection, and in-system programming via the single-wire debug interface. No external emulator is required - verified in Section 1.1.2 "Specifications" and Table 1.2 "Specifications for R8C/2A Group (2)" of the datasheet.
