Product details
Overview
R5F212A7SDFA#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2A Group, designed for embedded control in cost-sensitive industrial and consumer systems. It features 48 KB flash ROM, 2.5 KB RAM, 12-channel 10-bit A/D converter, dual 8-bit D/A converters, and operates from -40°C to +85°C (D version). Its integrated LIN module, three UARTs, I²C/SSU interface, and six timer units support motor control and sensor interfacing in appliance power supplies.
For engineers reviewing the R5F212A7SDFA#V2 datasheet, R5F212A7SDFA#V2 pinout, R5F212A7SDFA#V2 application, or R5F212A7SDFA#V2 equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing/peripheral behavior - all confirmed against Renesas' official R8C/2A Group documentation (Rev.2.10, Nov 2007).
Technical Context
The R5F212A7SDFA#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier, enabling efficient signal processing and real-time control loops. Its clock system includes XIN oscillator (up to 20 MHz), high-speed/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 timing: Timer RD provides 6-pin complementary PWM for three-phase motor drive with sawtooth/triangular wave modulation; Timer RC supports 3-pin PWM; and the hardware LIN module uses UART0 and Timer RA for ISO-9141/SAE J2602-compliant communication without CPU overhead.

FAQ
What is the maximum operating frequency and supply voltage range for R5F212A7SDFA#V2?
R5F212A7SDFA#V2 supports up to 20 MHz operation at VCC = 3.0–5.5 V, 10 MHz at 2.7–5.5 V, and 5 MHz at 2.2–5.5 V. These graded frequency/voltage combinations ensure reliable execution across wide input rail variations common in unregulated power supplies and battery-powered systems - all validated per Renesas R8C/2A Group specification tables.
Does R5F212A7SDFA#V2 include hardware LIN support?
Yes, R5F212A7SDFA#V2 integrates a hardware LIN module using UART0 and Timer RA to implement ISO-9141 and SAE J2602 protocols. This offloads LIN frame handling from the CPU, enabling deterministic response times and reducing firmware complexity - confirmed in Section 1.1.1 and Table 1.2 of the official R8C/2A Group datasheet.
What package type and pin count does R5F212A7SDFA#V2 use?
R5F212A7SDFA#V2 uses the PLQP0064GA-A package: a 64-pin LQFP with 0.8 mm pin pitch and 14 mm × 14 mm body. This matches the FA suffix in the part number and is explicitly listed in Table 1.5 (R8C/2A Product List) - distinct from FP (0.5 mm pitch) and LG (FLGA) variants.
How many A/D and D/A channels does R5F212A7SDFA#V2 provide?
R5F212A7SDFA#V2 includes a 10-bit A/D converter with 12 input channels (AN0–AN11) and two independent 8-bit D/A converters (DA0, DA1). These are physically mapped to P0_0–P0_7 pins and support simultaneous sampling - essential for closed-loop control in motor drives and power conversion, as specified in Tables 1.1 and 1.2.
Is on-chip debug functionality available for R5F212A7SDFA#V2?
Yes, R5F212A7SDFA#V2 supports on-chip debug with flash rewrite capability, allowing full firmware development, real-time variable inspection, and in-system programming without external debug probes.
