Renesas R5F212ACSNFP#V2

Overview

R5F212ACSNFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2A Group, featuring 128 KB flash ROM, 7.5 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 and office equipment.

For engineers reviewing the R5F212ACSNFP#V2 datasheet, R5F212ACSNFP#V2 pinout, R5F212ACSNFP#V2 application, or R5F212ACSNFP#V2 equivalent, key selection criteria include its N-version temperature range (−20°C to +85°C), 64-pin LQFP package (PLQP0064KB-A), on-chip debug support, and absence of data flash-distinguishing it from R8C/2B Group variants.

Technical Context

The R5F212ACSNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier for efficient arithmetic. Its memory architecture supports single-chip mode with 1 Mbyte address space, and it includes voltage detection (power-on reset + VDD monitor), programmable pull-up resistors on 55 CMOS I/O pins, and eight high-current drive ports.

Timing subsystems comprise three independent clock sources: XIN oscillator (up to 20 MHz), high-speed/low-speed on-chip oscillators (with frequency adjustment), and 32 kHz XCIN crystal input. Low-power modes include wait (2.1 µA @ 32 kHz) and stop (0.65 µA), with oscillation stop detection and selectable clock dividers (1/2/4/8/16).

FAQ

What is the maximum operating frequency and supply voltage range for R5F212ACSNFP#V2?

R5F212ACSNFP#V2 operates at up to 20 MHz when supplied at 3.0–5.5 V. At lower voltages, maximum frequency scales: 10 MHz at 2.7–5.5 V, and 5 MHz at 2.2–5.5 V. These ratings are validated per Renesas specification REJ03B0182-0210, ensuring timing compliance across the full voltage range without derating.

Does R5F212ACSNFP#V2 include data flash memory?

No, R5F212ACSNFP#V2 belongs to the R8C/2A Group and contains only program flash ROM (128 KB). It does not include the 2×1 KB data flash found in R8C/2B Group parts like R5F212BCSNFP#V2. This distinction is confirmed in Tables 1.1–1.4 and Figure 1.1 of the official datasheet.

What package type and pin count does R5F212ACSNFP#V2 use?

R5F212ACSNFP#V2 uses a 64-pin LQFP package with 0.5 mm pitch and 10 mm × 10 mm body, identified by package code PLQP0064KB-A. This is explicitly listed in Table 1.5 (Product List for R8C/2A Group) and Figure 1.1 of the Renesas documentation.

Which serial interfaces are integrated into R5F212ACSNFP#V2?

R5F212ACSNFP#V2 integrates three UARTs (UART0–UART2), one I²C bus (shared with SSU), one clock-synchronous serial I/O with chip select (SSU), and a hardware LIN module implemented using UART0 and Timer RA - all confirmed in Table 1.2 and Section 1.1.2 of the datasheet.

What is the operating temperature range for R5F212ACSNFP#V2?

R5F212ACSNFP#V2 is an N-version device rated for −20°C to +85°C ambient operating temperature, as defined in Table 1.2 and Figure 1.1. This classification aligns with Renesas' "Standard" quality grade for consumer and office equipment applications.
