ATF1500ABV's global input feedback architecture simplifies logic placement eliminates pinout changes design changes. ATF1500ABV bi-directional pins dedicated input pins. Each dedicated input also serve global control signal: register clock, register reset output enable. Each these control signals selected individually within each macrocell. Each logic macrocells generates buried feedback, which goes global bus. Each input also feeds into global bus. Because this global busing, each these signals always available macrocells device. Each macrocell also generates foldback logic term, which goes regional bus. signals within regional connected macrocells within region. Cascade logic between macrocells ATF1500ABV allows fast, efficient generation complex logic functions. ATF1500ABV contains such logic chains, each capable creating term logic with product terms. used power-down part. power-down option selected design source file. When enabled, device goes into power-down when high. power-down mode, internal logic signals latched held, enabled outputs. transitions ignored until brought low. When power-down feature enabled, cannot used logic input output. However, pin's macrocell still used generate buried foldback cascade logic signals. Each output also individual slew rate control. This used reduce system noise slowing down outputs that need operate maximum speed. Outputs default slow switching, specified fast switching design file.

INPUT
Bus-friendly Pin-keeper Input I/Os
input pins ATF1500ABV have programmable "data-keeper" circuits. activated, when driven high then subsequently left floating, will stay that previous high level. This circuitry prevents unused input lines from floating intermediate voltage levels, which cause unnecessary power consumption system noise. keeper circuits eliminate need external pull-up resistors eliminate their power consumption. Pin-keeper circuits disabled. Programming controlled logic design file. Once pin-keeper circuits disabled, normal termination procedures required unused inputs I/Os.

Speed/Power Management
ATF1500ABV several built-in speed power management features. ATF1500ABV contains circuitry that automatically puts device into low-power standby mode when logic transitions occurring. This only reduces power consumption during inactive periods, also provides proportional power savings most applications running system speeds below MHz. ATF1500ABVs also have optional pin-controlled power-down mode. this mode, current drops below When power-down option selected,

ATF1500ABV Macrocell
ATF1500ABV Macrocell
ATF1500ABV macrocell flexible enough support highly complex logic functions operating high speed. macrocell consists five sections: product terms product term select multiplexer; OR/XOR/CASCADE logic; flip-flop; output select enable; logic array inputs. Product Terms Select Each ATF1500ABV macrocell five product terms. Each product term receives inputs signals from both global regional bus. product term select multiplexer (PTMUX) allocates five product terms needed macrocell logic gates control signals. PTMUX programming determined design compiler, which selects optimum macrocell configuration. OR/XOR/CASCADE Logic ATF1500ABV macrocell's OR/XOR/CASCADE logic structure designed efficiently support types logic. Within single macrocell, product terms routed gate, creating five-input AND/OR term. With addition CASIN from neighboring macrocells, this expanded many product terms with very small additional delay. macrocell's gate allows efficient implementation compare arithmetic functions. input comes from term. other input product term fixed high level. combinatorial outputs, fixed-level input allows output polarity selection. registered functions, fixed levels allow Morgan minimization product terms. gate also used emulate JK-type flip-flops.

Flip-flop ATF1500ABV's flip-flop very flexible data control functions. data input come from either gate from separate product term. Selecting separate product term allows creation buried registered feedback within combinatorial output macrocell. addition operation, flip-flop also configured flow-through latch. this mode, data passes through when clock high latched when clock low. clock itself either global individual product term. flip-flop changes state clock's rising edge. When used clock, macrocell product terms selected clock enable. When clock enable function active enable signal (product term) low, clock edges ignored. flip-flop's asynchronous reset signal (AR) either global clear (GCLR), product term, always off. also logic GCLR with product term. asynchronous preset (AP) product term always off. Output Select Enable ATF1500ABV macrocell output selected registered combinatorial. When output registered, same registered signal back internally global bus. When output combinatorial, buried feedback either same combinatorial signal register output separate product term chosen flip-flop input. output enable multiplexer (MOE) controls output enable signals. buffer permanently enabled simple output operation. Buffers also permanently disabled allow input. this configuration macrocell resources still available, including buried feedback, expander CASCADE logic. output enable each macrocell also selected either pins individual product term. Global/Regional Buses global contains input signals well buried feedback signal from macrocells. Together with complement each signal, this provides 68-bit input every product term. Having entire global available each macrocell eliminates potential routing problems. With this architecture designs modified without requiring pinout changes. Each macrocell also generates foldback product term. This signal goes regional bus, available macrocells. foldback inverse polarity macrocell's product terms. foldback terms each region allow generation high fan-in terms product terms) with small additional delay.

Power-up Reset
ATF1500ABV's registers designed reset during power-up. point delayed slightly from crossing VRST, registers will reset state. result, registered output state will always power-up. This feature critical state machine initialization. However, asynchronous nature reset uncertainty actually rises system, following conditions required: rise must monotonic, from below volts. Signals from which clocks derived must remain stable during TPR. After occurs, input feedback setup times must before driving clock signal high.

Power-down Mode
ATF1500ABV includes optional controlled power-down feature. When this mode enabled, acts power-down pin. When high, device supply current reduced less than During power-down, output data internal logic states latched held. Therefore, registered combinatorial output data remain valid. outputs which were Hi-Z state onset power-down will remain Hi-Z. During power-down, input signals except power-down blocked. Input hold latches remain active insure that pins float indeterminate levels, further reducing system power. powerdown feature enabled logic design file. Designs using power-down logic array input. However, other macrocell resources still used, including buried feedback foldback product term array inputs.

Output Slew Rate Control
Each ATF1500ABV macrocell contains configuration each control output slew rate. This allows selected data paths operate maximum throughput while reducing system noise from outputs that speed-critical. Outputs default slow edges, individually fast design file. Output transition times outputs configured "slow" have delay adder.
Security Fuse Usage
single fuse provided prevent unauthorized copying ATF1500ABV fuse patterns. Once programmed, fuse verify preload prohibited. However, 160-bit User Signature remains accessible. security fuse should programmed last, effect immediate.
Register Preload
ATF1500ABV's registers provided with circuitry allow loading each register with either high low. This feature will simplify testing since state forced into registers control test sequencing. JEDEC file with preload generated when source file with preload vectors compiled. Once downloaded, JEDEC file preload sequence will done automatically when vectors approved programmers. preload mode enabled raising input high voltage level.
