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 |
