The GRP provides complete interconnectivity between all of these elements. The ispLSI 1048 features 5-Volt in-system programming and in-system diagnostic capabilities. It is the first device which 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 1048 devices is the Generic Logic Block (GLB). The GLBs are labeled A0, A1 .. F7 (see figure 1). There are a total of 48 GLBs in the ispLSI 1048 device. Each GLB has 18 inputs, a programmable AND/OR/XOR array, and four outputs which can be configured to be either combinatorial or registered. Inputs to the GLB come from the GRP and dedicated inputs. All of the GLB outputs are brought back into the GRP so that they can be connected to the inputs of any other GLB on the device. * ispDesignEXPERTTM - 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 ispANALYZERTM -- PC and UNIX Platforms Copyright (c) 1999 Lattice Semiconductor Corp.

All of these signals are made available to the inputs of the GLBs. Delays through the GRP have been equalized to minimize timing skew. The device also has 96 I/O cells, each of which is directly connected to an I/O pin. Each I/O cell can be individually programmed to be a combinatorial input, registered input, latched input, output or bi-directional I/O pin with 3-state control. Additionally, all outputs are polarity selectable, active high or active low. The signal levels are TTL compatible voltages and the output drivers can source 4 mA or sink 8 mA. Clocks in the ispLSI 1048 device are selected using the Clock Distribution Network. Four dedicated clockpins (Y0, Y1, Y2 and Y3) are brought into the distribution network, and five clock outputs (CLK 0, CLK 1, CLK 2, IOCLK 0 and IOCLK 1) are provided to route clocks to the GLBs and I/O cells. The Clock Distribution Network can also be driven from a special clock GLB (D0 on the ispLSI 1048 device). The logic of this GLB allows the user to create an internal clock from a combination of internal signals within the device. Eight GLBs, 16 I/O cells, two dedicated inputs (one dedicated input in Megablock B and E) and one ORP are connected together to make a Megablock (see figure 1). The outputs of the eight GLBs are connected to a set of 16 universal I/O cells by the ORP. The ispLSI 1048 device contains six of these Megablocks. 2 Specifications ispLSI 1048 Absolute Maximum Ratings 1 Supply Voltage Vcc .................................. -0.5 to +7.0V Input Voltage Applied ........................ -2.5 to VCC +1.0V Off-State Output Voltage Applied ..... -2.5 to VCC +1.0V Storage Temperature ................................ -65 to 150C Case Temp. with Power Applied .............. -55 to 125C U C SE O is M p M L ER SI C 10 IA 4 D L 8E ES & A IG IN F N D OR S U ST N R EW IA L Max.
