This military grade device contains 288 Registers, 96 Universal I/O pins, 12 Dedicated Input pins, two Global Output Enables (GOE), four Dedicated Clock Input pins and a Global Routing Pool (GRP). The GRP provides complete interconnectivity between all of these elements. The ispLSI 1048C/883 features 5-Volt insystem programming and in-system diagnostic capabilities. It is the first device which offers non-volatile reprogrammability of the logic, and the interconnect to provide truly reconfigurable systems. Compared to the ispLSI 1048, the ispLSI 1048C/883 offers two additional dedicated inputs and two new Global Output Enable pins. The basic unit of logic on the ispLSI 1048C/883 device is the Generic Logic Block (GLB). The GLBs are labeled A0, A1 .. F7 in figure 1. There are a total of 48 GLBs in the ispLSI 1048C/883 devices. 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. Copyright © 2002 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 a 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 have selectable polarity, active high or active low. The signal voltage levels are TTL-compatible, and the output drivers can source 4 mA or sink 8 mA. Clocks in the ispLSI 1048C/883 device are selected using the Clock Distribution Network. Four dedicated clock pins (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 1048C/883 device). The logic of this GLB allows the user to create an internal clock from a combination of internal signals. Eight GLBs, 16 I/O cells, two dedicated inputs and one ORP are connected together to make a Megablock as shown in figure 1. The outputs of the eight GLBs are connected to a set of 16 universal I/O cells by the ORP. Each ispLSI 1048C/883 device contains six Megablocks. 2 Specifications ispLSI 1048C/883 Absolute Maximum Ratings 1 Supply Voltage Vcc .................................. -0.5 to +7.0V Input Voltage Applied ........................ -2.5 to VCC +1.0V D D EV IS I C CE O PC NT H A N IN S #0 U B 5A ED EE -1 P N 0 ER Off-State Output Voltage Applied ..... -2.5 to VCC +1.0V Storage Temperature ................................ -65 to 150°C Case Temp. with Power Applied .............. -55 to 125°C Max.

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-48C-80-isp 9 Specifications ispLSI 1048C/883 Pin Description NAME DESCRIPTION CPGA PIN NUMBERS J2, L2, M3, P4, N9, N11, M12, L14, F13, D13, C12, A11, B6, B4, C3, D1, J3, K3, P2, M5, M9, M10, N14, K12, F12, E12, A13, C10, C6, C5, B1, E3, GOE0, GOE1 N13, B7, IN 2, IN 4 IN 6 - IN 11 P7, F14, P9 A9, K1, N1, N3, N5, P10, P13, M13, K13, E14, B14, B12, B10, A5, A2, C2, E2, L1, M2, M4, P5, P11, N12, L12, K14, D14, C13, C11, A10, A4, B3, D3, E1, K2, L3, P3, M6, N10, M11, M14, J12, E13, D12, A12, C9, B5, C4, C1, F3, M1, P1, N4, N6, P12, P14, L13, J13, C14, A14, B11, B9, A3, A1, D2, F2 Input/Output Pins - These are the general purpose I/O pins used by the logic array.
