[Introduction]:E33-433T13D is embedded in a high-speed low-power microcontroller and a high-performance chip SX1212. The transmission power is 20mW, and only 3.0mA is consumed in the receiving state. It has a single point wireless wake up function (only the waking object is specified, and all receivers do not need to exit the sleep mode). Single point wake up is a very important indicator, which can greatly save system power consumption.
Pin No. | Pin Item | Pin Direction | Pin Application |
---|---|---|---|
1 | M0 | Input(weak pull-up) | Work with M1 & decide the four operating modes. Floating is not allowed, can be ground. |
2 | M1 | Input(weak pull-up) | Work with M0 & decide the four operating modes. Floating is not allowed, can be ground. |
3 | RXD | Input | TTL UART inputs, connects to external TXD (MCU, PC) output pin.Can be configured as open-drain or pull-up input |
4 | TXD | Output | TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can be configured as open-drain or push-pull output |
5 | AUX | Output | To wake up the external MCU, during the procedure of self-check initialization, the pinoutputs low level. Can be configured as open-drain output or push-pull output (floatingis allowed). |
6 | VCC | Input | Power supply 2.3V-5.5V DC |
7 | GND | Input | Ground |
