Renesas R5F212F4DFP#W4

Overview

R5F212F4DFP#W4 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2F Group, designed for embedded control in cost-sensitive consumer and industrial applications. It integrates 16 KB program flash, 1 KB × 2 data flash (1 KB total), 1 KB RAM, a 10-bit 12-channel ADC, dual 8-bit DACs, two comparators, hardware LIN interface, and five timer modules-including 16-bit Timer RC with 4 capture/compare registers-operating at up to 20 MHz (V_CC = 3.0–5.5 V) in a 32-pin LQFP package.

For engineers reviewing the R5F212F4DFP#W4 datasheet, R5F212F4DFP#W4 pinout, R5F212F4DFP#W4 application, or R5F212F4DFP#W4 equivalent, key selection considerations include its -40°C to +85°C industrial temperature grade, on-chip data flash endurance (10,000 erase/write cycles), low-power stop mode (0.7 µA), hardware LIN compliance, and 32-pin PLQP0032GB-A package compatibility with standard 0.8 mm pitch PCB layouts.

Technical Context

The R5F212F4DFP#W4 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory architecture separates 16 KB program ROM (1,000-cycle endurance) from 1 KB dedicated data flash (10,000-cycle endurance), enabling reliable parameter storage without erasing application code.

Peripheral integration includes UART0 with LIN protocol support via Timer RA and UART0 co-configuration, four independent timers (RA/RB/RC/RE) supporting PWM, input capture, and event counting, and analog subsystems with sample-and-hold ADC, dual DACs, and dual comparators-all accessible through programmable CMOS I/O ports (25 pins, 8 high-current drive).

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212F4DFP#W4?

The R5F212F4DFP#W4 operates at up to 20 MHz when supplied with 3.0–5.5 V, achieving a minimum instruction execution time of 50 ns. At lower voltages (2.7–5.5 V), it supports 10 MHz operation with 100 ns instruction timing. These specifications are validated across its full -40°C to +85°C industrial temperature range, ensuring timing consistency in demanding environments.

Does the R5F212F4DFP#W4 include on-chip debug capability?

Yes, the R5F212F4DFP#W4 features on-chip debug functionality supporting real-time emulation and flash programming via the on-chip debug interface. This allows full visibility into CPU registers, memory, and peripheral states during development-enabling efficient firmware validation without requiring external debug probes beyond standard Renesas E1/E20 emulators.

How many analog-to-digital converter channels does the R5F212F4DFP#W4 support, and what is their resolution?

The R5F212F4DFP#W4 integrates a single 10-bit successive-approximation ADC with 12 input channels (AN0–AN11). It includes a built-in sample-and-hold circuit, allowing accurate conversion of fast-changing analog signals. Channel selection and conversion triggering are fully programmable via dedicated SFRs, supporting both single-shot and continuous scan modes.

What LIN protocol versions are supported by the R5F212F4DFP#W4 hardware module?

The R5F212F4DFP#W4 implements hardware-assisted LIN 2.0 and LIN 2.1 protocol compliance through coordinated operation of UART0 and Timer RA. The LIN module handles frame synchronization, checksum calculation (classic and enhanced), and response timing-reducing CPU overhead to under 5% during active communication and enabling deterministic slave-node behavior in automotive body electronics networks.

Is the R5F212F4DFP#W4 pin-compatible with other members of the R8C/2F Group?

Yes, all R8C/2F Group MCUs-including R5F212F4DFP#W4, R5F212F2DFP, R5F212F4NFP, and R5F212F2NFP-share identical 32-pin LQFP (PLQP0032GB-A) packaging and pin assignments. Firmware and PCB designs are interchangeable across these variants; differentiation lies solely in memory configuration (8 KB/16 KB ROM, 512 B/1 KB data flash) and temperature grade (D/N version).
