Actually the ATmega161(L) has been replaced by the ATmega162.

You can also use the Atmel Parametric Microcontrollers Selector by specifying to only display the devices which fulfill your requirements, 8-bit AVRs and a minimum of 2 UARTs.

Atmel Parametric Microcontrollers Selector

The selector returns a total of 24 currently recommended devices which have 2 or more UARTs:

Device Name
AT90CAN128
AT90CAN32
AT90CAN64
ATmega128
ATmega1280
ATmega1281
ATmega1284
ATmega1284P
ATmega128A
ATmega162
ATmega164A
ATmega164P
ATmega164PA
ATmega2560
ATmega2561
ATmega324A
ATmega324P
ATmega324PA
ATmega64
ATmega640
ATmega644A
ATmega644P
ATmega644PA
ATmega64A

The attached Excel file contains relevant information concerning all 24 Devices.

I want only 40 pin DIP IC.

I want only 40 pin DIP IC.

So what is your point!

Simply specify the 40 pin DIP package requirement as well in the Atmel Parametric Microcontrollers Selector.

Or download and examine the Excel file I've provided, which includes available packages for each model.

Over a dozen of the models I have previously listed above are available in a 40 pin DIP package.
