Dear guys
I have a chip,but the type was errased,no Logo,no type, so I wanna find the type of chip,It's very important to me !
And I list information about pin's function
And so many people tell me it's not a Microcontroller,it's like CPLD or other's programable device,
28 PIN SOP
1-4 pin input
5 pin 485 interface
6 pin 485 interface
7 pin GND
8-9 pin oscillator
10-14 output
15 pin output
16 pin output
17-18 pin output
19-20 pin output
21 pin VDD
22-28 pin output
