LC5768MB-75F256C FPGAs Overview
The ispXPLD 5000MX family represents a new class of device, referred to as
the eXpanded Programmable Logic Devices (XPLDs). These devices extend the
capability of Lattice’s popular SuperWIDE ispMACH 5000 architecture by providing
flexible memory capability. The family supports single- or dual-port SRAM, FIFO,
and ternary CAM operation. Extra logic has also been included to allow efficient
implementation of arithmetic functions. In addition, sysCLOCK PLLs and sysIO
interfaces provide support for the system-level needs of designers.
The devices
provide designers with a convenient one-chip solution that provides logic
availability at boot-up, design security, and extreme reconfigurability. The use
of advanced process technology provides industry-leading performance with
combinatorial propagation delay as low as 4.0ns, 2.8ns clock-to-out delay, 2.2ns
set-up time, and operating frequency up to 300MHz. This performance is coupled
with low static and dynamic power consumption. The ispXPLD 5000MX architecture
provides predictable deterministic timing.
The availability of 3.3, 2.5 and 1.8V
versions of these devices along with the flexibility of the sysIO interface
helps users meet the challenge of today’s mixed voltage designs. Inputs can be
safely driven up to 5.5V when an I/O bank is configured for 3.3V operation,
making this family 5V tolerant. Boundary scan testability further eases
integration into today’s complex systems. A variety of density and package
options increase the likelihood of a good fit for a particular application.
Table 1 shows the members of the ispXPLD 5000MX family.
