CY7C265

8K x 8 Registered PROM

are enabled. One pin on the CY7C265 is programmed to per-

form either the enable or the initialize function.

Features

• CMOS for optimum speed/power

• High speed (commercial and military)

— 15 ns address set-up

If the asynchronous enable (E) is being used, the outputs may

be disabled at any time by switching the enable to a logic

HIGH, and may be returned to the active state by switching the

enable to a logic LOW.

— 12 ns clock to output

• Low power

If the synchronous enable (ES) is being used, the outputs will

go to the OFF or high-impedance state upon the next positive

clock edge after the synchronous enable input is switched to a

HIGH level. If the synchronous enable pin is switched to a logic

LOW, the subsequent positive clock edge will return the output

tothe activestate. Followingapositive clock edge, theaddress

and synchronous enable inputs are free to change since no

change in the output will occur until the next LOW-to-HIGH

transitionof theclock. This uniquefeatureallows the CY7C265

decoders and sense amplifiers to access the next location

whilepreviously addresseddataremains stable on theoutputs.

— 660 mW (commercial)

— 770 mW (military)

• On-chip edge-triggered registers

— Ideal for pipelined microprogrammed systems

• EPROM technology

— 100% programmable

— Reprogrammable (7C265W)

• 5V ±10% V_CC, commercial and military

• Capable of withstanding >2001V static discharge

• Slim 28-pin, 300-mil plastic or hermetic DIP

If the E/I pin is used for INIT (asynchronous), then the outputs

are permanently enabled. The initialize function is useful dur-

ing power-up and time-out sequences, and can facilitate im-

plementation of other sophisticated functions such as a built-in

“jump start” address. When activated, the initialize control in-

put causes the contents of a user programmed 8193rd 8-bit

word to be loaded into the on-chip register. Each bit is pro-

grammable and the initialize function can be used to load any

desired combination of 1’s and 0’s into the register. In the un-

programmed state, activating INIT will generate a register

clear (all outputs LOW). If all the bits of the initialize word are

programmed to be a 1, activating INIT performs a register pre-

set (all outputs HIGH).

Functional Description

The CY7C265 is a 8192 x 8 registered PROM. It is organized

as 8,192 words by 8 bits wide, and has a pipeline output reg-

ister. In addition, the device features a programmable initialize

byte that may be loaded into the pipeline register with the ini-

tialize signal. The programmable initialize byte is the 8,193rd

byte in the PROM and its value is programmed at the time of

use.

Packaged in 28 pins, the PROM has 13 address signals (A₀

through A₁₂), 8 data out signals (O₀through O₇), E/I (enable

or initialize), and CLOCK.

Applying a LOW to the INIT input causes an immediate load of

the programmed initialize word into the pipeline register and

onto the outputs. The INIT LOW disables clock and must return

HIGH to enable clock independent of all other inputs, including

the clock.

CLOCK functions as a pipeline clock, loading the contents of

the addressed memory location into the pipeline register on

each rising edge. The data will appear on the outputs if they
