Outputs from the GLBs drive the Global Routing Pool
(GRP) between the GLBs. Switching resources are provided to allow signals in the Global Routing Pool to drive
any or all the GLBs in the device. This mechanism allows
fast, efficient connections across the entire device.
Each GLB contains 32 macrocells and a fully populated,
programmable AND-array with 160 logic product terms
and three extra control product terms. The GLB has 68
inputs from the Global Routing Pool which are available
in both true and complement form for every product term.
The 160 product terms are grouped in 32 sets of five and
sent into a Product Term Sharing Array (PTSA) which
allows sharing up to a maximum of 35 product terms for
a single function. Alternatively, the PTSA can be bypassed for functions of five product terms or less. The
three extra product terms are used for shared controls:
reset, clock, clock enable and output enable.

Specifications ispLSI 5256VE
The ispLSI 5000VE Family features 3.3V, non-volatile insystem programmability for both the logic and the
interconnect structures, providing the means to develop
truly reconfigurable systems. Programming is achieved
through the industry standard IEEE 1149.1-compliant
Boundary Scan interface. Boundary Scan test is also
supported through the same interface.
ispLSI 5000VE Description (Continued)
The 32 registered macrocells in the GLB are driven by the
32 outputs from the PTSA or the PTSA bypass. Each
macrocell contains a programmable XOR gate, a programmable register/latch and the necessary clocks and
control logic to allow combinatorial or registered operation. The macrocells each have two outputs, combinatorial
and registered. This dual output capability from the
macrocell allows efficient use of the hardware resources.
One output can be a registered function for example,
while the other output can be an unrelated combinatorial
function. A direct register input from the I/O pad facilitates efficient use of this feature to construct high-speed
input registers.
An enhanced, multiple cell security scheme is provided
that prevents reading of the JEDEC programming file
when secured. After the device has been secured using
this mechanism, the only way to clear the security is to
execute a bulk-erase instruction.
ispLSI 5000VE Family Members
Macrocell registers can be clocked from one of several
global or product term clocks available on the device. A
global and product term clock enable is also available to
each register, eliminating the need to gate the clock to the
macrocell registers. Reset for the macrocell register is
provided from the global signal, its polarity is userselectable. The macrocell register can be programmed to
operate as a D-type register or a D-type latch.
The ispLSI 5000VE Family ranges from 128 macrocells
to 512 macrocells and operates from a 3.3V power
supply. All family members will be available with multiple
package options. The ispLSI 5000VE Family device
matrix showing the various bondout options is shown in
the table below.
The interconnect structure (GRP) is very similar to Lattice's
existing ispLSI 1000, 2000 and 3000 families, but with an
enhanced interconnect structure for optimal pin locking
and logic routing. This eliminates the need for registered
I/O cells or an Output Routing Pool.
The 32 outputs from the GLB can drive both the Global
Routing Pool and the device I/O cells. The Global Routing
Pool contains one input from each macrocell output and
one input from each I/O pin.
The ispLSI 5000VE encompasses the innovative features of the ispLSI 5000VA family with several
enhancements. The macrocell is optimized and the Ttype flip flop option is removed. To improve the efficiency
of design fits, the Product Term Reset Logic is simplified
and the polarity option as well as the Global Preset
function are removed. The programmable output-delay
feature (skew option) is also removed. As a result, the
ispLSI 5000VE is not JEDEC compatible with the ispLSI
5000VA. ispLSI 5000VA and 5000VE pinouts may differ
in the same package, however all programming and
power/ground pins are located in the same locations.
The input buffer threshold has programmable TTL/3.3V/
2.5V compatible levels. The output driver can source
4mA and sink 8mA in 3.3V mode. The output drivers have
a separate VCCIO reference input which is independent
of the main VCC supply for the device. This feature allows
individual output drivers to drive either 3.3V (from the
device VCC) or 2.5V (from the VCCIO pin) output levels
while the device logic and the output current drive are
powered from device supply (VCC). The output drivers
also provide individually programmable edge rates and
open drain capability. A programmable pullup resistor is
provided to tie off unused inputs. Additionally, a programmable bus-hold latch is available to hold tristate outputs
in their last valid state until the bus is driven again by
some device.

pins, CLK2 and CLK3 can not only be inverted but are
also available for logic implementation through GRP
signal routing. Figure 5 shows these different clock
distribution options.
Global Clock Distribution
The ispLSI 5000VE Family has four dedicated clock input
pins: CLK0 - CLK3. CLK0 input is used as the dedicated
master clock that has the lowest internal clock skew with
no clock inversion to maintain the fastest internal clock

Specifications ispLSI 5256VE
Power Consumption
Power consumption in the ispLSI 5256VE device depends on two primary factors: the speed at which the
device is operating and the number of product terms
used. The product terms have a fuse-selectable speed/
power tradeoff setting. Each group of five product terms
has a single speed/power tradeoff control fuse that acts
on the complete group of five. The fast “high-speed”
setting operates product terms at their normal full power
consumption. For portions of the logic that can tolerate
longer propagation delays, selecting the slower “lowpower” setting will reduce the power dissipation for these
product terms. Figure 10 shows the relationship between
power and operating frequency.

Notes: Configuration of 16 16-bit Counters
Typical Current at 3.3V, 25° C
ICC can be estimated for the ispLSI 5256VE using the following equation:
High Speed Mode: ICC = 21 + (# of PTs * 0.313) + (# of nets * Fmax * 0.00282)
Low Power Mode: ICC = 21 + (# of PTs * 0.258) + (# of nets * Fmax * 0.00282)
# of PTs = Number of Product Terms used in design
# of nets = Number of Signals used in device
Fmax = Highest Clock Frequency to the device
The ICC estimate is based on typical conditions (VCC = 3.3V, room temperature) and an assumption of one GLB load
on average exists. These values are for estimates only. Since the value of ICC is sensitive to operating conditions
and the program in the device, the actual ICC should be verified.

Signal Descriptions
Signal Name
TMS
Description
Input - This pin is the Test Mode Select input, which is used to control the JTAG state machine.
TCK
Input - This pin is the Test Clock input pin used to clock through the JTAG state machine.
TDI
Input - This pin is the JTAG Test Data In pin used to load data.
TDO
Output - This pin is the JTAG Test Data Out pin used to shift data out.
TOE / I/O0
Input/Output - This pin functions as either the Test Output Enable pin or an I/O pin based upon
customer's design. TOE tristates all I/O pins when a logic low is driven.
GOE0, GOE1
Input - These two pins are the Global Output Enable input pins.
RESET
Dedicated Reset Input - This pin resets all registers in the device. The global polarity (active
high or low input) for this pin is selectable.
I/O
Input/Output – These are the general purpose I/O used by the logic array.
GND
Ground
NC1
No connect.
VCC
Vcc
CLK0, CLK1
Dedicated clock inputs for all registers. Both clocks are muxed before being used as the clock
input to all registers in the device.
CLK2 / I/O,
CLK3 / I/O
Input/Output - These pins share functionality. They can be used as dedicated clock inputs for
all registers, as well as I/O pins.
VCCIO
Input - This pin is used for optional 2.5V outputs. Every I/O can independently select either 3.3V
or the optional voltage as its output level. If the optional output voltage is not required, this pin
must be connected to the Vcc supply. Programmable pull-up resistors and bus-hold latches
only draw current from this supply.
1. NC pins are not to be connected to any active signals, VCC or GND.
