CY62127DV30LL-70ZI

Product Overview

The Cypress Semiconductor Corp CY62127DV30LL-70ZI is a 1 Mbit asynchronous SRAM from the MOBL series in a 44-TSOP II surface-mount package. It uses a 64K x 16 memory organization with a parallel interface, providing 70 ns access time and 70 ns word write cycle time. The device operates from a 2.2 V to 3.6 V supply and is specified for an ambient temperature range of -40°C to 85°C. Its volatile memory format and parallel bus structure support embedded systems that require direct read/write access to a 16-bit word-oriented SRAM array.

Key Features

• 1 Mbit volatile SRAM with a 64K x 16 memory organization
• Asynchronous parallel interface with 16-bit word access
• 70 ns access time and 70 ns word write cycle time
• 2.2 V to 3.6 V supply voltage range
• -40°C to 85°C ambient operating temperature range
• Surface-mount 44-TSOP II package

Applications

• Embedded data buffering in microcontroller-based systems
• Parallel memory expansion for 16-bit word-oriented buses
• Temporary storage in instrumentation and control electronics
• Asynchronous SRAM working memory for processor or FPGA interfaces

Design & Procurement Notes

When integrating this Cypress Semiconductor Corp SRAM, match the 2.2 V to 3.6 V supply domain and confirm that the controller or host bus can present 64K x 16 addressing with 16-bit data paths. The 70 ns access time and 70 ns write cycle time should be included in the host timing budget. The 44-TSOP II surface-mount package and -40°C to 85°C ambient range should be considered for PCB layout and thermal environment. Because the memory is volatile, data retention requires continuous power.
