Product details
Overview
R5F212F4NFP#W4 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller with 16 KB flash program ROM, 1 KB RAM, and dual 1 KB data flash blocks. It features a 20 MHz max operating frequency (VCC = 3.0–5.5 V), 10-bit 12-channel A/D converter, dual 8-bit D/A outputs, hardware LIN module, and operates from −20°C to +85°C in a 32-pin LQFP package. It targets embedded control in consumer appliances and office equipment.
For engineers reviewing the R5F212F4NFP#W4 datasheet, R5F212F4NFP#W4 pinout, R5F212F4NFP#W4 application, or R5F212F4NFP#W4 equivalent, key selection considerations include its on-chip data flash endurance (10,000 write/erase cycles), LIN bus support via UART0 + Timer RA, low-power stop mode (0.7 µA at 3.0 V), and 32-pin PLQP0032GB-A package compatibility with standard surface-mount assembly processes.
Technical Context
The R5F212F4NFP#W4 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and 16×16+32→32-bit multiply-accumulate capability. Its memory map allocates 1 Mbyte address space with fixed interrupt vectors at 0FFDCh–0FFFFh and supports single-chip operation without external bus interface.
It integrates four independent timers (RA, RB, RC, RE), including a 16-bit Timer RC with four capture/compare registers for PWM generation across three pins, plus UART0 with clock-synchronous serial I/O and dedicated hardware LIN protocol handling using TRAO, TRCIOA/B, and UART0 resources.
