Renesas R5F212BCSDFP#V2

Overview

R5F212BCSDFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2B Group, featuring 128 KB flash program memory, 2 KB on-chip data flash (1 KB × 2 blocks), 7.5 KB RAM, and operation over −40°C to +85°C. It integrates a 16-bit multiplier, 12-channel 10-bit A/D converter, dual 8-bit D/A converters, three UARTs, I²C/SSU, hardware LIN, and six advanced timers including complementary PWM for motor control. It targets embedded control in industrial appliances and automotive body electronics.

For engineers reviewing the R5F212BCSDFP#V2 datasheet, R5F212BCSDFP#V2 pinout, R5F212BCSDFP#V2 application, or R5F212BCSDFP#V2 equivalent, key selection criteria include its −40°C to +85°C industrial temperature grade, on-chip data flash endurance (10,000 erase/write cycles), 64-pin LQFP package (PLQP0064KB-A), integrated LIN physical layer support, and low-power stop mode current of 0.65 µA.

Technical Context

The R5F212BCSDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and executes at 50 ns minimum instruction time (20 MHz XIN, 3.0–5.5 V). Its clock system includes XIN/XOUT oscillation circuit with stop detection, high-/low-speed on-chip oscillators (with frequency adjustment), and 32 kHz XCIN/XCOUT real-time clock source.

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; UART0 is hardware-linked to Timer RA for LIN bus compliance; and the 12-channel A/D converter includes sample-and-hold for accurate signal acquisition in noisy environments.

FAQ

What is the maximum operating frequency of the R5F212BCSDFP#V2?

The R5F212BCSDFP#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 and usable as a clock source when external crystals are omitted, though with reduced accuracy.

Does the R5F212BCSDFP#V2 include hardware LIN support?

Yes, the R5F212BCSDFP#V2 integrates a hardware LIN module using UART0 and Timer RA to implement LIN 2.0/2.1 physical layer signaling. This eliminates the need for an external LIN transceiver in slave-node applications such as door modules or seat controllers.

What is the endurance specification for the on-chip data flash in the R5F212BCSDFP#V2?

The R5F212BCSDFP#V2 features 2 KB of on-chip data flash (1 KB × 2 blocks) rated for 10,000 erase/write cycles. This is distinct from its 128 KB program flash, which is rated for 1,000 cycles - making the data flash suitable for frequent parameter updates.

Which package type does the R5F212BCSDFP#V2 use?

The R5F212BCSDFP#V2 uses the 64-pin LQFP package with code PLQP0064KB-A: 0.5 mm pin pitch, 10 mm × 10 mm body size, and standard JEDEC-compliant footprint. This package is optimized for automated SMT assembly and thermal performance in dense PCB layouts.

What are the key low-power modes supported by the R5F212BCSDFP#V2?

The R5F212BCSDFP#V2 supports wait mode (2.1 µA at 3.0 V, 32 kHz XCIN) and stop mode (0.65 µA at 3.0 V), both retaining RAM content and enabling wake-up via external interrupt or RTC alarm. These modes are essential for battery-powered nodes requiring multi-year operation.
