It carries 128 KB of on-chip FLASH program memory and 4K x 8 of RAM — enough for a single control loop with moderate state tables, but not for data buffering beyond a few hundred bytes. The 100-TQFP package (14x14 mm body) is a fine-pitch quad flat pack that a rework station can handle with a hot-air nozzle and flux — no BGA underfill or X-ray inspection needed. The 0.5 mm pitch demands a steady hand and a decent soldering iron tip, but it's within reach of a well-equipped hobby bench. On-chip peripherals include POR (power-on reset), PWM outputs for dimming LEDs or driving a small DC motor, and a watchdog timer (WDT) that resets the part if the firmware hangs — no external supervisor IC needed for basic robustness. ## Analog and serial connectivity Eight 10-bit ADC channels and two 8-bit DAC channels give this MCU a genuine analog front-end — useful for reading potentiometers, joystick axes, or analog temperature sensors without an external ADC chip. The serial interfaces (Host Interface, I²C, IrDA, SCI) cover most sensor and display protocols: I²C for a small OLED or IMU, SCI for a UART-to-USB bridge, and IrDA for a short-range IR link. With 74 general-purpose I/O lines, you can drive a 16x2 character LCD in 4-bit mode, scan a 6x6 keypad matrix, and still have pins left for status LEDs and a buzzer. The I/O count is generous for a 100-pin package. ## Active lifecycle — no end-of-life pressure No stock-holding claim — quoted to order per RFQ.","metaTitle":"Renesas DF2148RTE20IV 16-bit MCU, 20MHz, 128KB Flash","metaDescription":"Renesas DF2148RTE20IV H8S/2100 16-bit MCU, 20MHz core, 128KB Flash, 4Kx8 RAM, 74 I/O, -40 to 85°C, 100-TQFP.
