CY62146DV30LL-55BVI

Product Overview

The CY62146DV30LL-55BVI from Cypress Semiconductor Corp is an active, surface-mount, asynchronous SRAM memory IC from the MOBL series. It provides 4 Mbit of volatile storage organized as 256K x 16 and uses a parallel memory interface. The device operates from a 2.2 V to 3.6 V supply, offers a 55 ns access time, and is supplied in a 48-VFBGA (6x8) package.

Key Features

• 4 Mbit volatile SRAM with 256K x 16 organization
• Asynchronous SRAM technology with 55 ns access time
• 55 ns word and page write cycle time
• 2.2 V to 3.6 V supply voltage range
• 48-VFBGA (6x8) surface-mount package
• Operating temperature range of -40°C to 85°C (TA)
• Active product lifecycle status
• Part of the MOBL series

Applications

• Parallel SRAM buffer or cache memory for embedded processors and controllers
• Temporary data storage in communication equipment using a 16-bit parallel memory bus
• Memory expansion in surface-mount embedded systems powered at 2.2 V to 3.6 V
• Volatile storage for instruments or terminals operating within the -40°C to 85°C ambient range

Design & Procurement Notes

When selecting this device, confirm that the host interface can drive a parallel 16-bit SRAM bus and meet the 55 ns access and write-cycle timing without adding unsupported wait-state assumptions. Verify the system supply remains within 2.2 V to 3.6 V and that the board layout supports the 48-VFBGA (6x8) surface-mount package. The -40°C to 85°C (TA) operating range should be checked against the enclosure environment. The supplied data lists the part as Active and does not verify programmability, so avoid assuming additional configuration features.
