Renesas R5F212B8SNFP#V2

Overview

R5F212B8SNFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2B Group, featuring 64 KB flash program memory, 1 KB × 2 on-chip data flash, 3 KB RAM, and operation at up to 20 MHz (VCC = 3.0–5.5 V). It integrates 12-channel 10-bit ADC, dual 8-bit DACs, six flexible timers (including PWM-capable Timer RD), three UARTs, I²C/SSU, hardware LIN, and operates from -20°C to +85°C in 64-pin LQFP (PLQP0064KB-A). It targets embedded control in consumer appliances and industrial HMI.

For engineers reviewing the R5F212B8SNFP#V2 datasheet, R5F212B8SNFP#V2 pinout, R5F212B8SNFP#V2 application, or R5F212B8SNFP#V2 equivalent, key selection considerations include its dual-block data flash endurance (10,000 erase/write cycles), real-time clock (Timer RE), low-power stop mode (0.65 µA), and hardware LIN support via UART0 + Timer RA - all confirmed for this exact N-version, 64-pin LQFP variant.

Technical Context

The R5F212B8SNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient arithmetic. Its memory architecture separates 64 KB flash program ROM (1,000-cycle endurance) from two independent 1 KB data flash blocks (10,000-cycle endurance), enabling reliable parameter storage without erasing application code.

Peripheral integration includes Timer RD (16-bit ×2, supporting three-phase complementary PWM with triangular/sawtooth modulation), three UARTs with LIN protocol acceleration, and a shared I²C/SSU interface. Clock sources comprise XIN oscillator (up to 20 MHz), high-speed/low-speed on-chip oscillators, and 32 kHz XCIN RTC input - all with oscillation stop detection and programmable frequency division.

FAQ

What is the maximum operating frequency and supply voltage range for R5F212B8SNFP#V2?

R5F212B8SNFP#V2 operates at up to 20 MHz when supplied with 3.0–5.5 V. At 10 MHz, it supports 2.7–5.5 V; at 5 MHz, the range extends down to 2.2 V. These specifications are confirmed in Table 1.4 of the R8C/2B Group datasheet (REJ03B0182-0210 Rev.2.10), and apply specifically to the N-version LQFP variant.

Does R5F212B8SNFP#V2 include on-chip data flash, and what is its endurance?

Yes, R5F212B8SNFP#V2 includes two 1 KB on-chip data flash blocks with 10,000 erase/write cycles - distinct from its 64 KB program flash (1,000-cycle endurance). This is explicitly stated in Table 1.4 and Figure 1.2 of the R8C/2B Group documentation, enabling reliable storage of calibration data and configuration parameters.

Which package type does R5F212B8SNFP#V2 use, and what are its mechanical dimensions?

R5F212B8SNFP#V2 uses the PLQP0064KB-A 64-pin LQFP package: 0.5 mm pin pitch, 10 mm × 10 mm body size, and standard gull-wing lead form. This is defined in Figure 1.2 and Table 1.6 of the R8C/2B Group datasheet, and matches the "FP" suffix in the part number.

How many UART interfaces does R5F212B8SNFP#V2 support, and is hardware LIN available?

R5F212B8SNFP#V2 supports three UART interfaces (UART0–UART2), with UART0 and Timer RA jointly implementing hardware LIN protocol acceleration. This capability is documented in Tables 1.3–1.4 and Section 1.1.1 of the R8C/2B Group datasheet, and applies to all R8C/2B variants including R5F212B8SNFP#V2.

What low-power modes are supported by R5F212B8SNFP#V2, and what is the minimum current draw?

R5F212B8SNFP#V2 supports wait and stop modes. In stop mode at 3.0 V with 32 kHz XCIN active, it draws just 0.65 µA - verified in Table 1.4. Wait mode consumes 2.1 µA under the same conditions. These values are specific to the N-version and confirmed for the PLQP0064KB-A package.
