Renesas R5F212A7SNFP#V2

Overview

R5F212A7SNFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2A Group, featuring 48 KB flash ROM, 2.5 KB RAM, and operation at up to 20 MHz (VCC = 3.0–5.5 V). It integrates a 10-bit 12-channel A/D converter, 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 consumer appliances requiring low-power operation down to 0.65 µA in stop mode.

For engineers reviewing the R5F212A7SNFP#V2 datasheet, R5F212A7SNFP#V2 pinout, R5F212A7SNFP#V2 application, or R5F212A7SNFP#V2 equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-A (64-pin LQFP), functional peripheral allocation, real-world use scenarios, and two validated alternative parts for design continuity.

Technical Context

The R5F212A7SNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier, enabling efficient signal processing and control loop execution. Its clock system includes XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz real-time clock), and programmable high-/low-speed on-chip oscillators with frequency adjustment.

Peripheral integration centers on deterministic timing control: Timer RD provides three-phase complementary PWM (6-pin output) with sawtooth/triangular modulation, while Timer RC and RF support input capture and output compare for motor phase sensing and encoder interfacing. The device lacks on-chip data flash-distinguishing it from R8C/2B Group variants-and operates within -20°C to +85°C (N version).

FAQ

What is the maximum operating frequency and supply voltage range for R5F212A7SNFP#V2?

R5F212A7SNFP#V2 operates at up to 20 MHz when supplied at 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 ratings ensure reliable timing margin across diverse power domains-from mains-powered appliances to battery-backed systems-without derating or external regulation beyond datasheet limits.

Does R5F212A7SNFP#V2 include on-chip data flash memory?

No, R5F212A7SNFP#V2 belongs to the R8C/2A Group and contains only program flash ROM (48 KB) with 1,000 write/erase cycles. It does not integrate data flash. For persistent parameter storage, external EEPROM or the R8C/2B Group variant R5F212B7SNFP#V2 (with 2 KB data flash) must be used.

Which package type corresponds to the R5F212A7SNFP#V2 part number suffix "FP"?

The "FP" suffix in R5F212A7SNFP#V2 denotes the PLQP0064KB-A package: a 64-pin LQFP with 0.5 mm pin pitch and 10 mm × 10 mm body. This is confirmed in Figure 1.1 and Table 1.5 of the R8C/2A Group datasheet REJ03B0182-0210, and is distinct from "FA" (larger pitch) and "LG" (FLGA) variants.

Can R5F212A7SNFP#V2 support hardware LIN communication?

Yes, R5F212A7SNFP#V2 implements a hardware LIN interface using UART0 combined with Timer RA for baud rate generation and synchronization, meeting ISO 17987 physical layer requirements. No external transceiver is needed for basic LIN master/slave operation, though an external LIN transceiver is required for bus-level voltage translation and fault protection.

What are the key low-power modes supported by R5F212A7SNFP#V2 and their typical current draw?

R5F212A7SNFP#V2 supports stop mode (0.65 µA @ 3.0 V), wait mode (2.1 µA @ 3.0 V with 32 kHz XCIN), and multiple active clock configurations. These modes are controlled via system registers and retain RAM content and register states, enabling rapid wake-up for event-driven applications like remote sensor polling or button press detection.
