CY27C256-150JC

Product Overview

The CY27C256-150JC from Cypress Semiconductor Corp is a non-volatile EPROM memory IC using one-time programmable (OTP) EPROM technology. It provides 256Kbit of storage in a 32K x 8 organization and uses a parallel memory interface. The device operates from a 4.5V to 5.5V supply and has a 150 ns access time. It uses a surface-mount 32-LCC (J-Lead) package, also designated 32-PLCC (13.97x11.43), and has an operating temperature range of 0°C to 70°C (TA).

Key Features

• 256Kbit non-volatile EPROM memory with 32K x 8 organization
• One-time programmable (OTP) EPROM technology for fixed program or data storage
• Parallel memory interface with 150 ns access time
• 4.5V to 5.5V supply voltage range
• Surface-mount 32-LCC (J-Lead) package with 32-PLCC (13.97x11.43) package designation
• 0°C to 70°C (TA) operating temperature range

Applications

• Non-volatile program storage in embedded controllers that use a parallel memory bus
• Storage of fixed calibration constants, configuration data, or lookup tables in instruments and controllers
• Parallel memory interfacing in systems requiring a 32K x 8 organization and 150 ns access time

Design & Procurement Notes

Designers should confirm that the target system can provide a 4.5V to 5.5V supply and can meet the timing requirements associated with a parallel memory interface and 150 ns access time. The 32K x 8 organization and OTP EPROM technology are suited to applications where the stored program or data is fixed after programming. The surface-mount 32-LCC (J-Lead) package and 32-PLCC (13.97x11.43) package designation should be checked against the PCB footprint, clearance, and soldering process. The 0°C to 70°C (TA) operating temperature range should be considered during thermal placement and board-level temperature conditions.
