The IA6850 uses innovASIC’s innovative new f 3 Program to provide industry with parts that other
vendors have declared obsolete. By specifying parts through this program a customer is assured of
never having a component become obsolete again. This advanced information sheet assumes the
original part has been designed in, and so provides a summary of capabilities only. For new designs
contact innovASIC for more detailed information.

Advanced Information Sheet
Asynchronous Communications Interface Adapter (ACIA)
The IA6850 is an ACIA megafunction used to interface a microprocessor to a serial communications
channel, and is functionally equivalent to the Motorola MC6850. This function receives and transmits
data in a variety of configurations including 7 or 8 bit data words, odd, even, or nor parity, and 1 or 2
stop bits.
A block diagram is shown in Figure 1.
