Overview
R5F212ACSDFA#X6 from Renesas Electronics is a 128 KB flash, 7.5 KB RAM 16-bit R8C/Tiny Series MCU in 64-pin LQFP (PLQP0064GA-A), operating from -40°C to +85°C. It integrates 12-channel 10-bit ADC, dual 8-bit DAC, three UARTs, I²C/SSU, hardware LIN, and six timer modules including PWM-capable Timer RD with 6-pin complementary output. Used in industrial motor control interfaces requiring real-time waveform generation and analog sensing.
For engineers reviewing the R5F212ACSDFA#X6 datasheet, R5F212ACSDFA#X6 pinout, R5F212ACSDFA#X6 application, or R5F212ACSDFA#X6 equivalent, key selection criteria include its D-grade temperature rating, on-chip LIN support tied to UART0 and Timer RA, 64-pin 0.8 mm pitch LQFP package, and absence of on-chip data flash (R8C/2A Group).
Technical Context
The R5F212ACSDFA#X6 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier. It supports single-chip mode with 1 Mbyte address space and executes instructions in as little as 50 ns at 20 MHz (VCC = 3.0–5.5 V).
Its peripheral set includes Timer RD (16-bit ×2, 6-pin PWM/complementary output), Timer RC (16-bit, 3-pin PWM), and UART0 configured for hardware LIN bus communication. Clock sources comprise XIN oscillator (up to 20 MHz), high-speed/low-speed on-chip oscillators, and 32 kHz XCIN crystal input.

FAQ
What is the maximum operating frequency of the R5F212ACSDFA#X6?
The R5F212ACSDFA#X6 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 up to 20 MHz, while the low-speed oscillator operates at 32 kHz for RTC and ultra-low-power modes.
Does the R5F212ACSDFA#X6 include on-chip data flash memory?
No, the R5F212ACSDFA#X6 belongs to the R8C/2A Group and contains only program flash memory (128 KB). It does not include on-chip data flash. For data flash functionality, consider the R8C/2B Group part R5F212BCSDFA#X6, which adds two 1 KB data flash blocks.
Which package type does the R5F212ACSDFA#X6 use?
The R5F212ACSDFA#X6 uses the 64-pin LQFP package with 0.8 mm pin pitch, designated PLQP0064GA-A (formerly 64P6U-A). This package measures 14 mm × 14 mm and is RoHS-compliant with lead-free surface finish.
What peripheral functions support hardware LIN communication on the R5F212ACSDFA#X6?
Hardware LIN on the R5F212ACSDFA#X6 is implemented using UART0 combined with Timer RA for baud rate generation and sync-break detection. This offloads LIN protocol handling from firmware, ensuring compliance with LIN 2.x specifications without CPU intervention during frame transmission or reception.
How many PWM output pins does the R5F212ACSDFA#X6 support in complementary mode?
The R5F212ACSDFA#X6 supports six complementary PWM output pins via Timer RD: P2_0/P2_1 (phase U), P2_2/P2_3 (phase V), and P2_4/P2_5 (phase W). These pins provide synchronized, dead-time-controlled outputs essential for driving 3-phase inverter bridges in motor control applications.
