1 Product description
UM2082F08 is an ultra-low-power 8-bit SOC chip based on a single-cycle 8051 core and has a three-channel low-frequency wireless wake-up ASK reception function. The chip can detect LF (low frequency) carrier frequency data in the range of 30KHz~300KHz and trigger a wake-up signal. At the same time, the receiving sensitivity can be adjusted to ensure reliable wake-up in various application environments. Its three independent channels can be configured for different wake-ups. mode and each channel has RSSI detection function, supports multiple data rate configurations, and supports Manchester encoding method. In addition, the chip integrates 32KB Flash, a maximum of 2KB+256B SRAM, a 12-bit 1Msps SARADC, and general peripheral communication interfaces such as UART, SPI, I2C, and PWM.
UM2082F08 has technical features such as high resource integration, high anti-interference performance, high reliability, low power consumption design and minimalist peripheral devices. Built-in high-speed clock ROSC, LDO and POR modules, the board-level circuit can eliminate the need for crystal oscillator, LDO and reset circuit. Low-frequency wireless wake-up uses an independent internal integrated clock signal generator. The clock source comes from the internal RC oscillator (32KHz). Users do not need to perform external calibration to maximize the chip's performance. Supports Keil MDK general integrated development environment, and supports C language and assembly language for software development.
