CY7C1325B-100BGC

Product Overview

The CY7C1325B-100BGC from Cypress Semiconductor Corp is a volatile SRAM IC with a 4.5Mbit capacity organized as 128K x 36. It uses a synchronous single-data-rate parallel memory interface and operates at a 100 MHz clock frequency with an 8 ns access time. The device is specified for a 3.15V to 3.6V supply voltage and an operating ambient temperature range of 0°C to 70°C. It is supplied in a surface-mount 119-BGA package, identified as 119-PBGA (14x22).

Key Features

• 4.5Mbit volatile SRAM memory format.
• 128K x 36 memory organization.
• SRAM - Synchronous, SDR technology.
• Parallel memory interface.
• 100 MHz clock frequency.
• 8 ns access time.
• 3.15V to 3.6V supply voltage range.
• 0°C to 70°C operating ambient temperature range.
• Surface-mount 119-BGA package.

Applications

• Buffering data transfers in embedded systems with parallel SRAM interfaces.
• Temporary storage for logic, DSP, or microcontroller subsystems.
• Memory expansion for boards using 36-bit parallel data paths.
• Data staging in test and measurement equipment.
• Frame or packet buffering in communication modules.

Design & Procurement Notes

When selecting this memory IC, confirm that the controller or bridge can address 128K x 36 locations and manage a synchronous, single-data-rate parallel bus at 100 MHz. The 8 ns access time should be checked against the system timing budget. The supply rail must remain within 3.15V to 3.6V, and the operating environment must stay within 0°C to 70°C ambient temperature. Because the device is surface-mounted in a 119-BGA package, PCB layout, reflow profile, and post-solder inspection should be planned for BGA assembly. The 36-bit organization also affects data-width matching and address decoding.
