CY62128DV30LL-55ZAIT

Product Overview

The CY62128DV30LL-55ZAIT from Cypress Semiconductor Corp is a volatile SRAM memory IC from the MOBL series. It provides 1 Mbit of memory organized as 128K x 8 and uses a parallel interface. The device is asynchronous, with a 55 ns access time and a 55 ns word/page write cycle time. It operates from a 2.2 V to 3.6 V supply and is specified for a temperature range of -40°C to 85°C (TA). The IC is supplied in a 32-TSOP surface-mount package.

Key Features

• 1 Mbit SRAM with a 128K x 8 organization
• Asynchronous memory technology with parallel interface
• 55 ns access time and 55 ns word/page write cycle time
• 2.2 V to 3.6 V supply voltage range
• Operating temperature range of -40°C to 85°C (TA)
• 32-TSOP surface-mount package

Applications

• Embedded systems that require volatile data buffering or scratch-pad storage
• Microprocessor or FPGA-based designs needing parallel SRAM memory expansion
• Instrumentation and measurement systems that require temporary storage of sampled data
• Communications equipment for short-term data buffering

Design & Procurement Notes

When selecting this device, verify that the system bus can accommodate a parallel SRAM interface and that address and data timing are compatible with the 55 ns access and write cycle specifications. The 2.2 V to 3.6 V supply range should be checked against the host logic voltage levels. The -40°C to 85°C (TA) operating range and 32-TSOP surface-mount package affect PCB layout, thermal considerations, and rework requirements. Because the memory is volatile, data retention depends on power. Decoupling and supply sequencing should be considered to maintain stable operation across the specified voltage range.
