SMALLEST 2.25V TO 5.5V UART WITH 16-BYTE FIFO AND POWERSAVE
The CPU interface is 8 data bits wide with 3 address lines and control signals to execute data bus read and
write transactions. The L580 data interface supports the Intel compatible types of CPUs and it is compatible to
the industry standard 16C550 UART. No clock (oscillator nor external clock) is required to operate a data bus
transaction. Each bus cycle is asynchronous using CS#, IOR# and IOW# or R/W# inputs. A typical data bus
interconnection for Intel and Motorola mode is shown in
