ispLSI 5000V Description
The ispLSI 5000V Family of In-System Programmable
High Density Logic Devices is based on Generic Logic
Blocks (GLBs) of 32 registered macrocells and a single
Global Routing Pool (GRP) structure interconnecting the
GLBs.
• ARCHITECTURE FEATURES
— Enhanced Pin-Locking Architecture with SingleLevel Global Routing Pool and SuperWide GLBs
— Wrap Around Product Term Sharing Array Supports
up to 35 Product Terms Per Macrocell
— Macrocells Support Concurrent Combinatorial and
Registered Functions
— Macrocell Registers Feature Multiple Control
Options Including Set, Reset and Clock Enable
— Four Dedicated Clock Input Pins Plus Macrocell
Product Term Clocks
— Slew and Skew Programmable I/O (SASPI/O™)
Supports Programmable Bus Hold, Pull-up, Open
Drain and Slew and Skew Rate Options
— Six Global Output Enable Terms, Two Global OE
Pins and One Product Term OE per Macrocell
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 5 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

drivers to drive either 3.3V or 2.5V output levels while the
device logic and the output current drive is always powered from 3.3V. The output drivers also provide individually
programmable edge rates and open drain capability. A
programmable pullup resistor is provided to tie off unused inputs and 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.
ispLSI 5000V Description (Continued)
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 five extra
product terms are used for shared GLB controls, set,
reset, clock, clock enable and output enable.
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/toggle flip-flop and the
necessary clocks and control logic to allow combinatorial
or registered operation. The macrocells each have two
outputs, which can be fed back through the Global
Routing Pool. 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.
The ispLSI 5000V 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.
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.
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 provided,
eliminating the need to gate the clock to the macrocell
registers. Reset and preset for the macrocell register is
provided from both global and product term signals. The
macrocell register can be programmed to operate as a Dtype register, a D-type latch or a T-type flip flop.
ispLSI 5000V Family Members
The ispLSI 5000V family ranges from 256 macrocells to
512 macrocells and operates from a 3.3V power supply.
All family members will be available with multiple package options. The ispLSI 5000V family device matrix
showing the various bondout options is shown in the table
below.
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 line from each macrocell
output and one line from each I/O pin.
The interconnect structure (GRP) is very similar to Lattice's
existing 1000, 2000 and 3000 families, but with an
enhanced interconnect structure for optimal pin locking
and logic routing. The ispLSI 5000V family does not,
however, use registered I/O cells or an Output Routing
Pool.
The input buffer threshold has programmable TTL/3.3V/
2.5V compatible levels. The output driver can source
4mA and sink 8mA. The output drivers have a separate
VCCIO reference input which is independent of the main
VCC supply for the device. This feature allows the output

The ispLSI 5000V 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 5256V
Power Consumption
Power Consumption in the ispLSI 5256V 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 four product terms has a
single speed/power tradeoff control fuse that acts on the
complete group of four. 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 significantly reduce the power
dissipation for these product terms.Figure 10 shows the
relationship between power and operating speed.

Notes: Configuration of 16 16-bit Counters
Typical Current at 3.3V, 25° C
ICC can be estimated for the ispLSI 5256V using the following equation:
High Speed Mode: ICC = 30 + (# of PTs * 0.456) + (# of nets * Max. freq * 0.0039)
Low Power Mode: ICC = 30 + (# of PTs * 0.22) + (# of nets * Max. freq * 0.0039)
# of PTs = Number of Product Terms used in design
# of nets = Number of Signals used in device
Max. freq = Highest Clock Frequency to the device
The ICC estimate is based on typical conditions (VCC = 3.3V, room temperature) and an assumption of 2 GLB loads
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.
GSET/GRST
Dedicated Set/Reset Input - This pin is available to all registers in the device and can
independently be configured as preset, reset or no effect on each register. The global polarity
(active high or low input) for this pin is also 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 function as either dedicated clock inputs for all registers or an I/O
pin based upon customer's design. Both clocks are muxed before being used as the clock input
to all registers in the device.
VCCIO
Input - This pin is used if an optional 2.5V output is to be used. 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.
