CY7C244-55WC

Product Overview

The Cypress Semiconductor Corp CY7C244-55WC is a 32Kbit non-volatile EPROM memory IC with a parallel interface and 55 ns access time. It uses UV-erasable EPROM technology and a 4K x 8 memory organization, and operates from a 4.5V to 5.5V supply voltage within an ambient temperature range of 0°C to 70°C. This device is for systems requiring parallel non-volatile program or data storage.

Key Features

• 32Kbit non-volatile EPROM memory.
• 4K x 8 memory organization with parallel interface.
• 55 ns access time.
• UV-erasable EPROM technology.
• 4.5V to 5.5V supply voltage range.
• 0°C to 70°C operating temperature (TA).

Applications

• Embedded controllers that require non-volatile program storage accessed over a parallel memory bus.
• Maintenance and service contexts where UV-erasable EPROM storage supports reprogramming of stored program data.
• 5V board-level memory subsystems needing a 4K x 8 organization for code or configuration data.
• Development or test environments using a parallel EPROM interface to hold non-volatile reference data.

Design & Procurement Notes

Designers should confirm that the host memory bus supports a parallel EPROM interface and that system timing tolerances are compatible with the 55 ns access time. The 4K x 8 organization and 32Kbit capacity determine address and data mapping requirements, while the 4.5V to 5.5V supply range and 0°C to 70°C operating temperature should be checked against board power and ambient conditions. Because the device uses UV-erasable EPROM technology, programming and erasure handling should be planned according to the memory format.
