Renesas R5F212A8SDFA#V2

Overview

R5F212A8SDFA#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2A Group, featuring 64 KB flash ROM, 3 KB RAM, and operation over −40°C to +85°C. It integrates a 16×16-bit multiplier, 10-bit A/D converter (12 channels), dual 8-bit D/A converters, three UARTs, I²C/SSU, hardware LIN, and six timer modules including PWM-capable Timer RD. It targets embedded control in industrial and consumer equipment requiring low-power operation and mixed-signal integration.

For engineers reviewing the R5F212A8SDFA#V2 datasheet, R5F212A8SDFA#V2 pinout, R5F212A8SDFA#V2 application, or R5F212A8SDFA#V2 equivalent, key selection criteria include its −40°C to +85°C industrial temperature grade, 64-pin LQFP (PLQP0064GA-A) package with 0.8 mm pitch, on-chip debug support, and absence of data flash (distinguishing it from R8C/2B variants).

Technical Context

The R5F212A8SDFA#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and minimum instruction execution time of 50 ns at 20 MHz. Its clock system includes XIN/XOUT (up to 20 MHz), high-/low-speed on-chip oscillators, and 32 kHz XCIN/XCOUT for real-time clock operation.

Peripheral integration includes Timer RA–RF (supporting input capture, PWM, three-phase waveform generation), UART0–2 with LIN capability, 10-bit A/D with sample-and-hold, and dual 8-bit D/A converters - all mapped to 55 CMOS I/O pins with selectable pull-up resistors and 8 high-current drive ports.

FAQ

What is the maximum operating frequency of the R5F212A8SDFA#V2?

The R5F212A8SDFA#V2 supports a maximum external crystal frequency of 20 MHz at VCC = 3.0 to 5.5 V, yielding a minimum instruction execution time of 50 ns. Its internal high-speed on-chip oscillator is adjustable and usable as a clock source when external crystals are unavailable. The R5F212A8SDFA#V2 does not support frequencies beyond 20 MHz in standard operating mode.

Does the R5F212A8SDFA#V2 include data flash memory?

No, the R5F212A8SDFA#V2 belongs to the R8C/2A Group and contains only program flash ROM (64 KB) and SRAM (3 KB). It does not integrate data flash. Devices with data flash - such as R5F212B8SDFA - belong to the R8C/2B Group and are functionally distinct despite identical pinouts and peripheral sets.

Which package type does the R5F212A8SDFA#V2 use?

The R5F212A8SDFA#V2 uses the PLQP0064GA-A 64-pin LQFP package with 0.8 mm pin pitch and 14 mm × 14 mm body size. This is confirmed by the "FA" suffix in the part number and documented in Renesas' R8C/2A Group product list (Table 1.5) and Figure 1.1.

What debug interface does the R5F212A8SDFA#V2 support?

The R5F212A8SDFA#V2 supports on-chip debug via a single-wire interface compatible with Renesas' E8/E8a debuggers. It does not require JTAG or SWD; debug access uses dedicated pins (e.g., P1_5/RXD0 and P1_4/TXD0 in debug mode) and enables full breakpoint, trace, and flash rewrite capabilities without external adapters.

Is the R5F212A8SDFA#V2 RoHS compliant?

Yes, the R5F212A8SDFA#V2 is RoHS compliant per EU Directive 2011/65/EU, as confirmed by Renesas' environmental compliance documentation and material declarations. Lead-free finish and halogen-free packaging meet industrial and consumer regulatory requirements without exemptions.
