description

The TIBPAL22VP10’ is equivalent to the
TIBPAL22V10A but offers additional flexibility in
the output structure. The improved output
macrocell uses the registered outputs as inputs
when in a high-impedance condition. This
provides two additional output configurations for a
total of six possible macrocell configurations all of
which are shown in Figure 1.

These devices contain up to 22 inputs and 10 outputs. They incorporate the unique capability of defining and
programming the architecture of each output on an individual basis. Outputs may be registered or nonregistered
and inverting or noninverting. In addition, the data may be fed back into the array from either the register or the
I/O port. The ten potential outputs are enabled through the use of individual product terms.

Further advantages can be seen in the introduction of variable product term distribution. This technique
allocates from 8 to 16 logical product terms to each output for an average of 12 product terms per output. This
variable allocation of terms allows far more complex functions to be implemented than in previously available
devices.

SRPS013 – D2943, FEBRUARY 1987 – REVISED JUNE 1991

description (continued)

Circuit design is enhanced by the addition of a synchronous set and an asynchronous reset product term. These
functions are common to all registers. When the synchronous set product term is a logic 1, the output registers
are loaded with a logic 1 on the next low-to-high clock transition. When the asynchronous reset product term
is a logic 1, the output registers are loaded with a logic 0. The output logic level after set or reset depends on
the polarity selected during programming. Output registers can be preloaded to any desired state during testing.
Preloading permits full logical verification during product testing.

With features such as programmable output logic macrocells and variable product term distribution, the
TIBP AL22VP10’ of fers quick design and development of custom LSI functions with complexities of 500 to 800
equivalent gates. Since each of the ten output pins may be individually configured as inputs on either a
temporary or permanent basis, functions requiring up to 21 inputs and a single output or down to 12 inputs and
10 outputs are possible.

A power-up clear function is supplied that forces all registered outputs to a predetermined state after power is
applied to the device. Registered outputs selected as active-low power-up with their outputs high. Registered
outputs selected as active-high power-up with their outputs low.

A single security fuse is provided on each device to discourage unauthorized copying of fuse patterns. Once
blown, the verification circuitry is disabled and all other fuses will appear to be open.

power-up reset

Following power up, all registers are reset to zero. The output level depends on the polarity selected during
programming. This feature provides extra flexibility to the system designer and is especially valuable in
simplifying state-machine initialization. To ensure a valid power-up reset, it is important that the rise of V
monotonic. Following power-up reset, a low-to-high clock transition must not occur until all applicable input and

programming information

Texas Instruments programmable logic devices can be programmed using widely available software and
inexpensive device programmers.

When the additional fuses are not being used, the TIBPAL22VP10 can be programmed using the
TIBP AL22V10/10A programming algorithm. The fuse configuration data can either be from a JEDEC file (format
per JEDEC Standard No. 3-A) or a TIBPAL22V10/10A master.

Complete programming specifications, algorithms, and the latest information on hardware, software, and
firmware are available upon request. Information on programmers capable of programming T exas Instruments
programmable logic is also available, upon request, from the nearest TI field sales office, local authorized TI
distributor, or by calling Texas Instruments at [phone].

NOTES: A. CL includes probe and jig capacitance and is 50 pF for tpd and ten, 5 pF for t

B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. W aveform 2

is for an output with internal conditions such that the output is high except when disabled by the output control.

C. All input pulses have the following characteristics: For C suffix, use the voltage levels indicated in parentheses ( ). PRR ≤ 1 MHz,

tr = tf ≤ 2 ns, duty cycle = 50%. For M suffix, use the voltage levels indicated in brackets [ ]. PRR ≤ 10 MHz, tr and tf ≤ 2 ns,

duty cycle = 50%.
D. When measuring propagation delay times of 3-state outputs, switch S1 is closed.
E. Equivalent loads may be used for testing.
