The ispLSI 3448 features 5V in-system programmability and in-system diagnostic capabilities. The ispLSI 3448 offers non-volatile reprogrammability of the logic, as well as the interconnect to provide truly reconfigurable systems. The basic unit of logic on the ispLSI 3448 device is the Twin Generic Logic Block (Twin GLB) labelled A0, A1...N3. There are a total of 56 of these Twin GLBs in the ispLSI 3448 device. Each Twin GLB has 24 inputs, a programmable AND array and two OR/Exclusive-OR Arrays, and eight outputs which can be configured to be either combinatorial or registered. All Twin GLB inputs come from the GRP. • ispDesignEXPERT™ – LOGIC COMPILER AND COMPLETE ISP DEVICE DESIGN SYSTEMS FROM HDL SYNTHESIS THROUGH IN-SYSTEM PROGRAMMING — Superior Quality of Results — Tightly Integrated with Leading CAE Vendor Tools — Productivity Enhancing Timing Analyzer, Explore Tools, Timing Simulator and ispANALYZER™ — PC and UNIX Platforms Copyright © 2000 Lattice Semiconductor Corp.

Contact Rochester Electronics for Availability. www.latticesemi.com/sales/discontinueddevicessales.cfm Functional Block Diagram Specifications ispLSI 3448 Clocks in the ispLSI 3448 device are provided through five dedicated signals. Three clocks are provided for the Twin GLBs and the remaining two clocks are provided for the I/O cells. All local logic block outputs are brought back into the GRP so they can be connected to the inputs of any other logic block on the device. The device also has 224 I/O cells, each of which is directly connected to an I/O ball. Each I/O cell can be individually programmed to be a combinatorial input, a registered input, a latched input, an output or a bidirectional I/O with 3-state control. The signal levels are TTL compatible voltages and the output drivers can source 4 mA or sink 8 mA. Each output can be programmed independently for fast or slow output slew rate to minimize overall output switching noise. The table below lists key attributes of the device along with the number of resources available. An additional feature of the ispLSI 3448 is the Boundary Scan capability, which is composed of cells connected between the on-chip system logic and the device’s inputs and outputs. All I/O have associated boundary scan registers, with 3-state I/O using three boundary scan registers and inputs using one. The 224 I/O cells are grouped into 14 sets of 16 bits. Each of these I/O groups is associated with a logic Megablock through the use of the ORP. Each Megablock is able to provide one Product Term Output Enable (PTOE) signal which is globally distributed to all I/O cells. That PTOE signal can be generated within any GLB in the Megablock. Each I/O cell can select one of 16 available OEs (two Global OEs and 14 PTOEs). The ispLSI 3448 supports all IEEE 1149.1 mandatory instructions, which include BYPASS, EXTEST and SAMPLE. Key Attributes of the ispLSI 3448 Attribute Four Twin GLBs, 16 I/O cells and one ORP are connected together to make a logic Megablock. The Megablock is defined by the resources that it shares. The outputs of the four Twin GLBs are connected to a set of 16 I/O cells by the ORP. The ispLSI 3448 device contains 14 of these Megablocks. The GRP has as its inputs the outputs from all of the Twin GLBs and all of the inputs from the bidirectional I/O cells. All of these signals are made available to the inputs of the Twin GLBs. Delays through the GRP have been equalized to minimize timing skew and logic glitching.

Figure 3 shows the relationship between power and operating speed. Figure 3.

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. 0127A/3448 10 Discontinued Product (PCN #06-07).

GOE0, GOE1 Global Output Enable inputs. TOE Test Output Enable pin – This pin tristates all I/O pins when a logic low is driven. RESET Active Low (0) Reset which resets all of the GLB and I/O registers in the device. Y0, Y1, Y2 Dedicated Clock inputs connect to one of the clock inputs of all the GLBs on the device.

High-to-low transition will put the device in the programming mode and put all I/O in the high-Z state. TDI/SDI Input – This signal performs two functions. It is the Test Data input signal when ispEN is logic high. When ispEN is logic low, it functions as an input to load programming data into the device. SDI is also used as one of the two control signals for the ISP State Machine. TCK/SCLK Input – This signal performs two functions. It is the Test Clock input signal when ispEN is logic high. When ispEN is logic low, it functions as a clock signal for the Serial Shift Register. TMS/MODE Input – This signal performs two functions. It is the Test Mode Select input signal when ispEN is logic high. When ispEN is logic low, it controls the operation of the ISP State Machine. TRST Input – Test Reset, active low to reset the Boundary Scan State Machine. TDO/SDO Output – This signal performs two functions. When ispEN is logic low, it reads the ISP data.
