  • Data Rate 

  • 2.4/4.8/9.6/19.2/38.4/76.8/153.6Kbps

  • Current Consumption 

  • +10dBm output 26.4mA 

  • 0dBm output 15mA

  • Dispose 

  • After power program, restore TWS-900C. 

  • Wait for 1ms, and then dispose TWS-900C. 

  • After dispose, enable transmit data to TWS-900C at least 5ms time delay. 

  • In order to simplify the program, the number of package can not beyond 64 BYTE for once. (In principle, it can have illimitably BYTE.)

  • Frequency Formulation 

  • Frequency value = actual working frequency*2^16/26000000, frequency value address : 0x0D, 0x0E and 0x0F. 

  • Ex : Working frequency = 434M, frequency value : 

  • = 434*2^16/26 = 1093947 = 0x10B13B,then 

  • 0x0D = 0x10 

  • 0x0E = 0xB1 

  • 0x0F = 0x3B 

  • Restore TWS-900C 

  • Dispose high/low CE, more than 10us time delay. 

  • Dispose high CE; have to equal or more than 50us T1 time delay.

  • Reset instruction : 0x30. 

  • When CE become low (After T1 time), suggest RD status 

  • If it shows 1, keep waiting. (if beyond 20ms, indicate bad module.) 

  • If it shows 0, then transmit reset instruction to RF.

  • Wait for RD status after finish reset instruction transmitting 

  • If it shows 1, make CE to 1 after wait for others turn to 0. 

  • If it shows 0, make CE to 1. 

  • After restoration, the are as below

Write in orders to RF module 

Write in two orders after finish dispose : 0x37/0x33 

Write in two orders before transfer : 0x3B/0x35 

Write in two orders before enter low power consumption : 0x39/0x32 

From low power consumption to normal : Reset, dispose. 

When CE become low, have to wait for RD become low to transfer data to RF

Special description 

0DH , 0EH ,0FH are the address for working frequency.

06H is the number of BYTE for once package. It will be 0AH if it transfers 10 Units once. 

After reset and write the dispose above in RF, write in two orders : 0x37/0x33 

If would like to know the data in 06H is correct or not, change the address to 0x80 and read RD data, as same as reading others address. The graphs are as same as while write in, reference as below : 


RFID|Wireless Modules|RF Module|Wireless VIDEO


In order to matching TRW-400 transfer data, it have accord with the form below, or TRW-400 can not receive data 

Address + BYTE*n data + checkup code

Address (BYTE*n) the transfer number have to be the same as RX value. 

Check code (include two BYTE, the value of these two BYTE are the same), 55?address?data. Ex : Transmit address is 4 BYTE, its value : 0x12345678. Data is 8 BYTE, its value : 0x01020304050607. Check code : 0x5D5D. 

Transmit address is 0x7F+0x12345678+0x01020304050607+0x5D5D. 

After CE becomes low, check RD line to see if it is 0 or not. Transfer address if it is 0, or keep waiting.

Write in two orders to RF module before transfer data every time. 0x3B/0x35 

After all data transferred, check FLAG is 1 or not 

If 1, transfers the next package after it become low. 

If 0, transfers the next package after it become low later than high. 

Graph of transfer data are as below
