The DE4 board uses the ADM3202 transceiver chip and a 9-pin D-SUB connector for RS-232
communication. For detailed information on how to use the transceiver, refer to the datasheet
which is available on the manufacturer’s website, or in the
Datasheet/RS232
folder on the
DE4
System CD-ROM
.
Table 2–28
lists the RS-232 pin assignments, signal names and functions.

The DE4 development board features a 64MB PC28F512P30BFA CFI-compliant NOR-type flash
memory device which is part of the shared FMS Bus consisting of flash memory, SSRAM, and the
Max II CPLD (EPM2210) System Controller. The single synchronous flash memory with 16-bit
data bus supports 4-word, 8-word 16-word, and continuous-word burst mode provides non-volatile
