Product details
Overview
R5F212E2NFP#W4 from Renesas Electronics is an 8 KB flash-based 16-bit R8C/Tiny Series MCU with 512 bytes RAM, operating at up to 20 MHz (VCC = 3.0–5.5 V), featuring 12-channel 10-bit A/D, dual 8-bit D/A converters, hardware LIN interface, and 32-pin LQFP package for embedded control in consumer appliances and office equipment.
For engineers reviewing the R5F212E2NFP#W4 datasheet, R5F212E2NFP#W4 pinout, R5F212E2NFP#W4 application, or R5F212E2NFP#W4 equivalent, key selection considerations include its N-version temperature range (−20°C to +85°C), absence of on-chip data flash, 7-level interrupt priority, and integrated LIN module using UART0 and Timer RA.
Technical Context
The R5F212E2NFP#W4 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. It executes instructions in as little as 50 ns at 20 MHz and supports single-chip mode with 1 Mbyte address space.
Its peripheral set includes four independent timers (RA, RB, RC, RE), UART0 with clock-synchronous serial I/O, two comparators, and a voltage detection circuit with power-on reset and VDD monitor. The device lacks on-chip data flash-distinguishing it from R8C/2F Group variants-and targets cost-sensitive industrial and consumer applications requiring moderate integration and low-power operation.
Key Specifications

FAQ
What is the maximum operating frequency and supply voltage range for the R5F212E2NFP#W4?
The R5F212E2NFP#W4 operates at up to 20 MHz when supplied with 3.0–5.5 V, and at up to 10 MHz down to 2.7 V. Its minimum instruction execution time is 50 ns under 20 MHz/5.0 V conditions, enabling deterministic real-time response in time-critical control tasks.
Does the R5F212E2NFP#W4 include on-chip data flash memory?
No, the R5F212E2NFP#W4 does not include on-chip data flash. It belongs to the R8C/2E Group, which provides only program flash ROM (8 KB) and RAM (512 bytes). Data flash is exclusive to the R8C/2F Group, such as the R5F212F2NFP.
How many analog input channels and what resolution does the A/D converter in R5F212E2NFP#W4 support?
The R5F212E2NFP#W4 integrates a 10-bit A/D converter with 12 input channels (AN0–AN11), including sample-and-hold functionality. This allows simultaneous sampling of multiple sensors-such as temperature, voltage, and current feedback-without external sample-hold circuitry.
What peripherals enable LIN bus communication on the R5F212E2NFP#W4?
The R5F212E2NFP#W4 implements hardware LIN 2.0 using UART0 for serial framing and Timer RA for precise baud rate generation and sync field timing. This offloads LIN protocol handling from firmware, ensuring compliance without CPU-intensive bit-banging.
What is the operating ambient temperature range specified for the R5F212E2NFP#W4?
The R5F212E2NFP#W4 is rated for −20°C to +85°C (N version), as indicated by the "N" in its part number. This qualifies it for commercial and industrial applications but excludes extended-temperature automotive or outdoor deployment without derating.
