[Interface]:UART

[Introduction]:E64-433T20S is applicable for star network with low power consumption. The biggest feature is to support at most 31 slaves send data to master at the same time and WOR mode for slaves(the average current is below 30uA). Data reliability and accuracy are guaranteed by strict data parity and automatic retransmission mechanism between master and slave.

E64-433T20S
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 (MCU, PC) TXD 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 indicate module's working status & wakes up the external MCU. During the procedure of self-check initialization, the pin outputs low level. Can be configured as open-drain output or push-pull output. (Floating is allowed)
6 VCC Input Power supply 2.1V~5.5V DC
7 GND Input Ground electrode
8 ANT Output Reference places of high frequency signal output
9 GND Input/Output Antenna interface( high frequencysignal output)
10 GND Input Ground electrode
11 GND Input Ground electrode
