Renesas Electronics Corporation Embedded - Microcontrollers R5F100LEDFB#50

The R5F100LEDFB#50 is a microcontroller from Quarktwin Technology Ltd. that operates on a true low-power platform, consuming 66 OºA/MHz and as low as 0.57 OºA in specific modes. It supports a voltage range of 1.6 V to 5.5 V and features a 16 to 512 Kbyte code flash memory. The microcontroller is built on the RL78 CPU core, utilizing a CISC architecture with a 3-stage pipeline, allowing for flexible instruction execution times from 0.03125 Oºs at 32 MHz to 30.5 Oºs at 32.768 kHz. The device includes a variety of integrated features such as an on-chip debug function, self-programming capabilities, and a data flash memory of 4 KB to 8 KB with a typical rewrite endurance of 1,000,000 times. It also incorporates a high-speed on-chip oscillator with selectable frequencies, a DMA controller, and multiple serial interfaces including SPI, UART, and I¬=C. The operating temperature range is suitable for both consumer and industrial applications, extending from -40¬8C to +105¬8C depending on the variant. Engineers considering this microcontroller will find it suitable for general-purpose applications requiring low power consumption, extensive memory options, and robust peripheral support.
