CY7C1339A-66AC

Product Overview

The CY7C1339A-66AC from Cypress Semiconductor Corp is a volatile SRAM integrated circuit with a 4Mbit capacity and a 128K x 32 organization. It uses a synchronous SDR architecture and a parallel memory interface, operating with a clock frequency of 66 MHz and an access time of 7 ns. The device is supplied in a surface-mount 100-LQFP package, identified as 100-TQFP (14x20), and is specified for a 3.15 V to 3.6 V supply and an operating temperature range of 0°C to 70°C (TA).

Key Features

• 4Mbit SRAM capacity organized as 128K x 32 for parallel memory access
• Synchronous SDR operation at a 66 MHz clock frequency
• 7 ns access time specified for the parallel SRAM interface
• 3.15 V to 3.6 V supply range
• Surface-mount 100-LQFP package with a 100-TQFP (14x20) device package
• Operating temperature range of 0°C to 70°C (TA)

Applications

• Volatile data buffering in embedded systems using a synchronous parallel SRAM interface
• Temporary storage in equipment operating within a 0°C to 70°C ambient range
• Memory expansion for controllers requiring a 128K x 32 organization
• Parallel memory subsystems in 66 MHz clocked designs

Design & Procurement Notes

When selecting this part, confirm that the board supply can maintain 3.15 V to 3.6 V and that the controller can drive a parallel 128K x 32 SRAM interface at 66 MHz. The 7 ns access time should be considered with the system clock and timing budget. Layout should account for the surface-mount 100-LQFP package and the 100-TQFP (14x20) footprint. Thermal and environmental limits should also be checked against the 0°C to 70°C (TA) operating range.
