CY27C010-70ZC

Product Overview

The Cypress Semiconductor Corp CY27C010-70ZC is a 1Mbit nonvolatile EPROM memory IC with a parallel interface and 128K x 8 organization. It uses an OTP memory technology, provides 70 ns access time, and operates from a 4.5V to 5.5V supply. The device is offered in a 32-TSOP I surface-mount package, with a 32-TFSOP body width of 0.724 in (18.40 mm), and is specified for an ambient operating temperature range of 0°C to 70°C.

Key Features

• 1Mbit nonvolatile EPROM memory with one-time programmable (OTP) technology and 128K x 8 organization
• Parallel memory interface with 70 ns access time
• Supply voltage range of 4.5V to 5.5V
• Surface-mount 32-TSOP I package, corresponding to 32-TFSOP (0.724 in, 18.40 mm width)
• Operating temperature range of 0°C to 70°C (TA)
• Memory format specified as EPROM for nonvolatile data storage

Applications

• Fixed firmware storage in embedded systems that use a 5V parallel memory bus
• One-time programming of calibration constants or configuration data in measurement instruments
• Nonvolatile lookup-table storage in designs requiring a parallel EPROM memory interface

Design & Procurement Notes

Design teams should confirm that the PCB footprint matches the 32-TSOP I surface-mount package and that the board supply can maintain 4.5V to 5.5V during operation. Because the device is a 1Mbit parallel EPROM with 70 ns access time, system timing budgets should allow for this access window and the 128K x 8 address/data organization. The OTP memory technology means programming strategy and data preparation should be verified before device programming, since the memory is one-time programmable. Thermal design should consider the 0°C to 70°C ambient operating range.
