description

The TIBPSG507AC is

a 13 × 80 × 8

Programmable Sequence Generator (PSG) that

offers the system designer unprecedented

flexibility

high-performance

field-programmable logic device. Applications

such as waveform generators, state machines,

dividers, timers, and simple logic reduction are all

possible with the PSG. By utilizing the built-in

binary counter, the PSG is capable of generating

complex timing controllers. The binary counter

also simplifies logic equation development in state

machine and waveform generator applications.

The TIBPSG507AC contains 80 product (AND)

terms, a 6-bit binary counter with control logic,

eight S/R state holding registers, and eight

outputs. The eight outputs can be individually

NC – No internal connection

programmed

for

either

registered

combinational operation. The clock input is fuse

programmable for either positive- or negative-

edge operation.

The 6-bit binary counter is controlled by a synchronous-clear and a count/hold function. Each control function

has a nonregistered and registered option. When either SCLR0 or SCLR1 is taken high, the counter resets to

zero on the next active clock edge. When either CNT/HLD0 or CNT/HLD1 is taken high, the counter is held at

the present count and is not allowed to advance on the active clock edge. The SCLR function overrides the

CNT/HLD feature when both lines are simultaneously high.

Clock polarity is programmable through the clock polarity fuse. Leaving this fuse intact selects positive-edge

triggering. Negative-edge triggering is selected by blowing this fuse. Pin 17 functions as an input and/or an

output enable. When the output enable fuse is intact, all outputs are always enabled allowing pin 17 to be used

strictly as an input. Blowing the output enable fuse lets pin 17 function as an output enable and an input. In this

mode, the outputs are enabled when pin 17 is low and are in a high-impedance state when pin 17 is high.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
