CY62128DV30L-55ZAI

Product Overview

The CY62128DV30L-55ZAI from Cypress Semiconductor Corp is a volatile SRAM memory IC from the MOBL series. It provides 1 Mbit of storage in a 128K x 8 organization and uses a parallel interface. The device operates from a 2.2 V to 3.6 V supply and has a 55 ns access time and 55 ns write cycle time. It is packaged in a 32-TSOP surface-mount package with a 32-TFSOP case size of 0.465 in (11.80 mm) width, and its operating temperature range is -40°C to 85°C.

Key Features

• 1 Mbit volatile SRAM organized as 128K x 8
• Parallel memory interface with 55 ns access time
• 55 ns write cycle time for word and page writes
• 2.2 V to 3.6 V supply voltage range
• 32-TSOP surface-mount package; 32-TFSOP 0.465 in / 11.80 mm width
• Operating temperature range of -40°C to 85°C

Applications

• Temporary data storage in embedded systems using an 8-bit parallel SRAM interface
• Buffer memory for microcontroller-based instrumentation and control boards
• Scratchpad memory for data processing units operating from 2.2 V to 3.6 V

Design & Procurement Notes

When selecting this device, match the 128K x 8 organization and parallel bus width to the host memory controller or microprocessor. The 55 ns access and write timing should be checked against the system clock and address/control setup requirements. Board layout must accommodate the 32-TSOP surface-mount footprint and the 32-TFSOP 0.465 in (11.80 mm) width. The 2.2 V to 3.6 V supply range and -40°C to 85°C operating range should be aligned with the intended powered environment. Because the memory type is volatile, retention depends on maintaining supply voltage.
