Renesas R5F212B8SDFP#V2

Overview

R5F212B8SDFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU in the R8C/2B Group, featuring 64 KB flash program memory, 1 KB × 2 on-chip data flash, 3 KB RAM, and operation over −40°C to +85°C. It integrates an 89-instruction CPU core with 16×16→32-bit multiplier, 12-channel 10-bit ADC, dual 8-bit DACs, three UARTs, I²C/SSU, hardware LIN, and six advanced timers (including complementary PWM and three-phase control). It targets embedded control in industrial sensors and motor-driven consumer appliances.

For engineers reviewing the R5F212B8SDFP#V2 datasheet, R5F212B8SDFP#V2 pinout, R5F212B8SDFP#V2 application, or R5F212B8SDFP#V2 equivalent, key selection considerations include its −40°C to +85°C D-version temperature rating, 64-pin LQFP (PLQP0064KB-A) package, on-chip data flash endurance (10,000 write/erase cycles), real-time clock (Timer RE), and LIN bus support via UART0 and Timer RA.

Technical Context

The R5F212B8SDFP#V2 implements the R8C/Tiny CPU core with single-chip mode and 1 Mbyte address space, executing instructions in as little as 50 ns at 20 MHz (VCC = 3.0–5.5 V). Its clock system includes XIN/XOUT oscillation (up to 20 MHz), high-/low-speed on-chip oscillators (with frequency adjustment), and 32 kHz XCIN/XCOUT for low-power RTC operation.

Peripheral integration centers on deterministic real-time control: Timer RD supports reset-synchronous and complementary PWM for three-phase motor drive (6-pin output), Timer RC provides 4-register capture/compare for encoder input, and the LIN module uses UART0 with Timer RA for ISO 9141-2/SAE J2602-compliant communication without software bit-banging.

FAQ

What is the maximum operating frequency and supply voltage range for R5F212B8SDFP#V2?

R5F212B8SDFP#V2 operates at up to 20 MHz when supplied at 3.0–5.5 V, delivering a minimum instruction execution time of 50 ns. At reduced frequencies (10 MHz or 5 MHz), it supports down to 2.7 V or 2.2 V respectively-enabling flexible power management in battery-powered designs where R5F212B8SDFP#V2 maintains full peripheral functionality across its rated voltage window.

Does R5F212B8SDFP#V2 support hardware LIN communication?

Yes, R5F212B8SDFP#V2 integrates a dedicated hardware LIN module that combines UART0 and Timer RA to implement ISO 9141-2 and SAE J2602 protocols without CPU intervention. This allows R5F212B8SDFP#V2 to serve as a slave node in automotive body networks or industrial distributed control systems with deterministic response and minimal firmware overhead.

How many analog-to-digital converter channels does R5F212B8SDFP#V2 provide, and what is their resolution?

R5F212B8SDFP#V2 includes a 10-bit successive-approximation ADC with 12 input channels and integrated sample-and-hold circuitry. All 12 channels are accessible via dedicated pins (AN0–AN11), enabling simultaneous monitoring of multiple analog sensors-such as thermistors, potentiometers, or current shunts-within a single R5F212B8SDFP#V2-based subsystem.

What is the endurance specification for the on-chip data flash in R5F212B8SDFP#V2?

The on-chip data flash in R5F212B8SDFP#V2 is rated for 10,000 write/erase cycles per block (1 KB × 2), significantly exceeding the 1,000-cycle endurance of its main program flash. This allows R5F212B8SDFP#V2 to reliably store frequently updated parameters-like calibration offsets or usage counters-throughout the product's operational lifetime without external nonvolatile memory.

Which package type and pin count does R5F212B8SDFP#V2 use?

R5F212B8SDFP#V2 uses a 64-pin LQFP package with code PLQP0064KB-A: 0.5 mm pin pitch, 10 mm × 10 mm body size, and standard JEDEC footprint. This package is pin-compatible with other R8C/2B Group MCUs in the same family, enabling scalable design reuse across memory and feature variants while maintaining PCB layout compatibility for R5F212B8SDFP#V2.
