CY7C1325B-100BGCT

Product Overview

The CY7C1325B-100BGCT from Cypress Semiconductor Corp is a volatile synchronous SRAM memory IC with 4.5 Mbit capacity and 128K x 36 organization. It uses a parallel memory interface and is specified for operation at 100 MHz with an 8 ns access time. The device operates from a 3.15 V to 3.6 V supply and is rated for an ambient temperature range of 0°C to 70°C (TA). It is supplied in a surface-mount 119-PBGA (14x22) package.

Key Features

• 4.5 Mbit volatile SRAM memory capacity
• Synchronous single-data-rate architecture with 100 MHz clock frequency
• 128K x 36 memory organization with parallel interface
• 8 ns access time
• 3.15 V to 3.6 V supply voltage range
• 0°C to 70°C ambient operating temperature range
• Surface-mount 119-PBGA (14x22) package

Applications

• Temporary storage of 36-bit data words in synchronous digital systems using a parallel memory interface
• Buffering of data in systems that operate at 100 MHz and require an 8 ns access time
• Board-level memory expansion in equipment powered from 3.15 V to 3.6 V and operating in 0°C to 70°C ambient conditions

Design & Procurement Notes

Design considerations include routing the 36-bit parallel bus and clock signals to support the 100 MHz synchronous interface while respecting the 3.15 V to 3.6 V supply range. The 8 ns access time and 128K x 36 organization should be matched to system timing and data-width requirements. The 119-PBGA surface-mount package and 0°C to 70°C ambient operating range are relevant to board layout and thermal management.
