Product details
Overview
R5F212ACSDFP#X6 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU in the R8C/2A Group, featuring 128 KB flash ROM, 7.5 KB RAM, and operation across -40°C to +85°C (D version). It integrates a 16×16-bit multiplier, 12-channel 10-bit ADC, dual 8-bit DACs, three UARTs, I²C/SSU, hardware LIN, and six timer modules including PWM-capable Timer RD and real-time clock Timer RE - deployed in industrial control panels requiring deterministic timing and mixed-signal interfacing.
For engineers reviewing the R5F212ACSDFP#X6 datasheet, R5F212ACSDFP#X6 pinout, R5F212ACSDFP#X6 application, or R5F212ACSDFP#X6 equivalent, key selection criteria include its 64-pin LQFP (PLQP0064KB-A) package, D-grade temperature rating, absence of on-chip data flash (distinguishing it from R8C/2B variants), and support for LIN bus via UART0+Timer RA - critical for automotive body electronics and appliance motor control designs.
Technical Context
The R5F212ACSDFP#X6 implements the R8C/Tiny CPU core with 89 fundamental instructions and single-chip 1 Mbyte address space. Its clock system includes XIN oscillator (up to 20 MHz), high-/low-speed on-chip oscillators, and 32 kHz XCIN RTC source, with selectable frequency dividers (1/2/4/8/16) and oscillation stop detection.
Peripheral integration centers on deterministic real-time control: Timer RD provides 6-pin complementary PWM for three-phase motor drive; Timer RC supports 3-pin PWM and input capture; UART0 pairs with Timer RA for hardware LIN 2.0 compliance; and the 12-channel ADC includes sample-and-hold for simultaneous sampling in sensor acquisition systems.
Key Specifications

FAQ
What is the maximum operating frequency of the R5F212ACSDFP#X6?
The R5F212ACSDFP#X6 supports up to 20 MHz external crystal frequency (XIN) at VCC = 3.0–5.5 V, delivering a minimum instruction execution time of 50 ns. This enables real-time response in motor control loops and fast ADC conversions without external clock multiplication.
Does the R5F212ACSDFP#X6 include on-chip data flash memory?
No, the R5F212ACSDFP#X6 belongs to the R8C/2A Group and contains only program flash ROM (128 KB). It lacks the 2×1 KB data flash found in R8C/2B Group variants like R5F212BCSDFP#X6 - making it suitable for applications where parameters are stored in ROM or external EEPROM.
Which package type does the R5F212ACSDFP#X6 use?
The R5F212ACSDFP#X6 uses the 64-pin LQFP package with code PLQP0064KB-A: 0.5 mm pin pitch, 10 mm × 10 mm body size, and exposed pad for thermal dissipation - optimized for automated SMT assembly and industrial PCB layouts with constrained space.
How many UART interfaces does the R5F212ACSDFP#X6 support?
The R5F212ACSDFP#X6 integrates three independent UART modules (UART0, UART1, UART2), each with full-duplex capability and configurable baud rates. UART0 is hardware-linked to Timer RA for LIN 2.0 compliance, while UART2 serves as a dedicated debug or host interface.
What is the operating temperature range for the R5F212ACSDFP#X6?
The R5F212ACSDFP#X6 is rated for -40°C to +85°C (D version), validated for continuous operation across this range under specified VCC conditions. This makes it suitable for under-hood automotive modules and industrial enclosures without active cooling.
