ispXPGA Family Data Sheet

Configuration and Programming
The ispXPGA family of devices takes a unique approach to FPGA configuration memory. It contains two types of
memory, Static RAM and non-volatile E
2CMOS cells. The static RAM is used to control the functionality of the
device during normal operation and the E
2CMOS memory cells are used to load the SRAM. The E2CMOS memory
module can be thought of as the hard drive for the ispXPGA configuration and the SRAM as the working configura-
tion memory. There is a one-to-one relationship between SRAM memory and the E
2CMOS cells. The SRAM can
be configured either from the E
2CMOS memory or from an external source, as shown in Figure 21.
Figure 21 shows the different ports and modes that are used in the configuration and programming of the ispXPGA
devices. There are two possible ports that can be used for configuration of the SRAM memory: the ISP port which
supports the IEEE 1149.1 Test Access Port (TAP) Std., accommodates bit-wide configuration. The sysCONFIG
port allows byte-wide configuration of the SRAM configuration memory. When programming the E
2CMOS memory,
only the 1149.1 TAP can be used.
Configuration and programming done through the 1149.1 Test Access Port (TAP) supports both the IEEE Std.
1149.1 Boundary Scan TAP specification and the IEEE Std. 1532 In-System Configuration specification. To config-
ure or program the device using the 1149.1 TAP the device must be in the ISP mode. To configure the SRAM mem-
ory using the sysCONFIG Port, the device must be in the sysCONFIG mode. Upon power-up, the device’s SRAM
memory can be configured either from the E
2CMOS memory or from an external source through the sysCONFIG
mode. Additionally, the SRAM can be re-configured from the E
2CMOS memory by executing a “REFRESH.” See
TN1026, ispXP Configuration Usage Guidelines, for more in depth information on the different programming
modes, timing and wake-up.

Supports IEEE 1149.1 Boundary Scan Testability
All ispXPGA devices have boundary scan cells and supports the IEEE 1149.1 standard. This allows functional test-
ing of the circuit board on which the device is mounted through a serial scan path that can access all critical logic
notes. Internal boundary scan registers are linked internally, allowing test data to be shifted in and loaded directly
onto test nodes, or test node data to be captured and shifted out for verification. In addition, these devices can be
linked into a board-level serial scan path for more board level testing.
Security Scheme
A programmable security scheme is provided on the ispXPGA devices as a deterrent to unauthorized copying of
the array configuration patterns. Once programmed, the security scheme prevents read-back of the programmed
SRAM
