CY7C277
Functional Description
The user may define the polarity of the ALE signal, with the
default being active HIGH.
The CY7C277 is a high-performance 32K word by 8-bit CMOS
PROMs. It is packaged in the slim 28-pin 300-mil package.
The ceramic package may be equipped with an erasure window; when exposed to UV light, the PROM is erased and can
then be reprogrammed. The memory cells utilize proven
EPROM floating-gate technology and byte-wide algorithms.
The CY7C277 offers the advantages of low power, superior
performance, and high programming yield. The EPROM cell
requires only 12.5V for the supervoltage and low current requirements allow for gang programming. The EPROM cells
allow for each memory location to be 100% tested, as each
location is written into, erased, and repeatedly exercised prior
to encapsulation. Each PROM is also tested for AC performance to guarantee that the product will meet DC and AC
specification limits after customer programming.
On the 7C277, the outputs are pipelined through a master-slave register. On the rising edge of CP, data is loaded into
the 8-bit edge triggered output register. The E/ES input provides a programmable bit to select between asynchronous
and synchronous operation. The default condition is asynchronous. When the asynchronous mode is selected, the E/ES pin
operates as an asynchronous output enable. If the synchronous mode is selected, the E/ES pin is sampled on the rising
edge of CP to enable and disable the outputs. The 7C277 also
provides a programmable bit to enable the Address Latch input. If this bit is not programmed, the device will ignore the ALE
pin and the address will enter the device asynchronously. If the
ALE function is selected, the address enters the PROM while
the ALE pin is active, and is captured when ALE is deasserted.

Notes:
1. Contact a Cypress representative for industrial temperature range specifications.
2. TA is the “instant on” case temperature.
3. See the last page of this specification for Group A subgroup testing information.
4. See “Introduction to CMOS PROMs” in this Book for general information on testing.
5. For devices using the synchronous enable, the device must be clocked after applying these voltages to perform this measurement.
6. For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
