Renesas R5F212BASDFP#V2

Overview

R5F212BASDFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU in the R8C/2B Group, featuring 96 KB flash program memory, 1 KB × 2 on-chip data flash, 7 KB RAM, and operation over −40°C to +85°C. It integrates a 16×16-bit multiplier, 10-bit ADC (12 channels), dual 8-bit DACs, three UARTs, I²C/SSU, hardware LIN, and six advanced timers including complementary PWM for motor control. It targets embedded control in industrial and consumer equipment requiring nonvolatile data storage and low-power operation.

For engineers reviewing the R5F212BASDFP#V2 datasheet, R5F212BASDFP#V2 pinout, R5F212BASDFP#V2 application, or R5F212BASDFP#V2 equivalent, key selection criteria include its −40°C to +85°C D-version qualification, dual 1 KB data flash blocks for EEPROM-like wear leveling, 64-pin LQFP (PLQP0064KB-A) package with 55 CMOS I/Os, and integrated LIN physical layer support via UART0 and timer RA.

Technical Context

The R5F212BASDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and single-cycle multiply-accumulate capability (16×16→32 + 32→32). Its clock system includes XIN/XOUT (up to 20 MHz), high-speed/low-speed on-chip oscillators, and 32 kHz XCIN/XCOUT for real-time clock operation - all with oscillation stop detection and selectable frequency division (1/2/4/8/16).

Peripheral integration centers on deterministic timing control: Timer RD provides reset-synchronous and complementary PWM for three-phase motor drives; Timer RC and RF support input capture and output compare for encoder interfacing; UART0 is hardwired to timer RA for LIN 2.0 compliance; and the 10-bit ADC includes sample-and-hold across all 12 channels with configurable trigger sources.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212BASDFP#V2?

The R5F212BASDFP#V2 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 20 MHz/3.0 V conditions. The device supports dynamic voltage scaling across this range without requiring external regulators or level shifters.

Does the R5F212BASDFP#V2 support hardware LIN communication, and how is it implemented?

Yes, the R5F212BASDFP#V2 includes a dedicated hardware LIN module compliant with LIN 2.0. It combines UART0 with timer RA to handle header detection, checksum calculation, and response timing autonomously - eliminating CPU intervention during frame transmission and improving real-time determinism in automotive body networks.

How many analog-to-digital converter channels does the R5F212BASDFP#V2 provide, and what is their resolution?

The R5F212BASDFP#V2 integrates a 10-bit successive-approximation ADC with 12 input channels (AN0–AN11), all supported by an internal sample-and-hold circuit. Channels are distributed across ports P0 (AN0–AN7), P1 (AN8–AN11), and support software- or timer-triggered conversions with configurable sampling windows.

What type of data flash is included in the R5F212BASDFP#V2, and what is its endurance rating?

The R5F212BASDFP#V2 includes two independent 1 KB on-chip data flash blocks, rated for 10,000 erase/write cycles each. This enables EEPROM-emulation functionality with built-in wear leveling - critical for storing calibration data, usage counters, or configuration parameters that survive power loss and field updates.

Is the R5F212BASDFP#V2 pin-compatible with other members of the R8C/2B Group, such as R5F212B8SDFP#V2 or R5F212BCSDFP#V2?

Yes, the R5F212BASDFP#V2 is fully pin-compatible with all 64-pin LQFP variants in the R8C/2B Group, including R5F212B8SDFP#V2 and R5F212BCSDFP#V2. They share identical PLQP0064KB-A packaging, I/O mapping, peripheral pin assignments, and electrical characteristics - enabling drop-in replacement for firmware scalability or cost optimization.
