W3150A+与W3150A的区别:

 

W3150A+ W3150A
Three MCU interface
(Direct, Indirect and SPI)
Only two interface possible
Pin no.33 used for SPI enable Pin no.33 used for PCLOCK
Interrupt Register clear by writing on particular bit Interrupt Register clear by
Add "Send_OK" interrupt is added reading the register
when send operation is complete No interrrupt when send operation is complete
No delayed ACK mode supported in TCP Not possible
UDP zero checksum is removed in TX UDP zero checksum is there in TX and RX both
