APEX 20KC Programmable Logic Device Data Sheet
6
All APEX 20KC devices are reconfigurable and are 100% tested prior to
shipment. As a result, test vectors do not have to be generated for fault-
coverage purposes. Instead, the designer can focus on simulation and
design verification. In addition, the designer does not need to manage
inventories of different application-specific integrated circuit (ASIC)
designs; APEX 20KC devices can be configured on the board for the
specific functionality required.
APEX 20KC devices are configured at system power-up with data stored
in an Altera serial configuration device or provided by a system
controller. Altera offers in-system programmability (ISP)-capable EPC16,
EPC8, EPC4, EPC2, and EPC1 configuration devices and one-time
programmable (OTP) EPC1 configuration devices, which configure
APEX 20KC devices via a serial data stream. Moreover, APEX 20KC
devices contain an optimized interface that permits microprocessors to
configure APEX 20KC devices serially or in parallel, and synchronously
or asynchronously. The interface also enables microprocessors to treat
APEX 20KC devices as memory and configure the device by writing to a
virtual memory location, making reconfiguration easy.
