Renesas Electronics Corporation Microcontrollers R5F11TLEDFB#30

The R5F11TLEDFB#30 microcontroller from Quarktwin Technology Ltd. is designed for low-power applications, particularly in electric power meter systems. It operates within a voltage range of 1.9 V to 5.5 V and features a 64 KB to 256 KB flash memory capacity. The device utilizes a RL78 CPU core with a CISC architecture, supporting a minimum instruction execution time of 0.03125 ¬µs at 32 MHz. It includes a high-speed on-chip oscillator with selectable frequencies and a power management system that features multiple low-power modes. This microcontroller supports a variety of peripherals, including a 24-bit OîO£ A/D converter, multiple serial interfaces (SPI, UART, I¬=C), and an AES encryption circuit with various cipher modes. It also has an extensive I/O capability, with up to 68 configurable pins, and includes built-in functions for power-on reset and voltage detection. The operating temperature range is -40 to +85¬8C, making it suitable for a wide range of environmental conditions. The product is packaged in a 64-pin LFQFP format, facilitating integration into compact designs.
