CY7C1339A-100AC

Product Overview

The CY7C1339A-100AC from Cypress Semiconductor Corp is a volatile synchronous SRAM device providing 4 Mbit of memory in a 128K x 32 organization. It uses a parallel interface and operates as a single data rate synchronous memory at a 100 MHz clock frequency, with an 8 ns access time. The device is specified for a 3.15 V to 3.6 V supply range and an ambient operating temperature range of 0°C to 70°C. It is supplied in a 100-TQFP (14x20) surface-mount package for board-level designs requiring a 32-bit-wide SRAM buffer.

Key Features

• 3.15 V to 3.6 V supply voltage range
• 0°C to 70°C operating temperature range
• 100-TQFP (14x20) surface-mount package

Applications

• Buffer memory in FPGA or microprocessor systems using a 32-bit parallel bus
• Temporary data storage in communications or networking equipment operating within the 0°C to 70°C ambient range
• Data capture or processing subsystems requiring synchronous SRAM access

Design & Procurement Notes

Design considerations should focus on the 3.15 V to 3.6 V supply window, the 100 MHz synchronous timing requirements, and the 32-bit parallel data path. Because the memory is volatile, system design must account for data loss when power is removed. The 100-TQFP (14x20) surface-mount package requires compatible PCB land patterns and thermal management within the 0°C to 70°C ambient operating range. The 8 ns access time and SDR operation should be matched to the controller clock and access timing requirements.
