CY62137BV18LL-70BAI

Product Overview

CY62137BV18LL-70BAI from Cypress Semiconductor Corp is a volatile SRAM memory IC organized as 128K x 16 for a total capacity of 2 Mbit. The device uses an asynchronous parallel interface and specifies a 70 ns access time and 70 ns write cycle time for word/page operations. It operates from a 1.75 V to 1.95 V supply and is rated for an ambient operating temperature range of -40°C to 85°C. The component uses a 48-FBGA (7x7) surface-mount package, with a 48-TFBGA package/case designation, for printed circuit board assembly.

Key Features

• 70 ns access time and 70 ns word/page write cycle time
• 1.75 V to 1.95 V supply voltage range
• -40°C to 85°C ambient operating temperature range
• 48-FBGA (7x7) surface-mount package

Applications

• Random-access volatile storage in embedded controller designs
• Data buffering for systems using parallel memory buses
• Temporary storage in measurement, control, or processing equipment
• Memory expansion in circuit boards requiring a 128K x 16 organization

Design & Procurement Notes

For selection, confirm that the system supply rail falls within 1.75 V to 1.95 V and that the controller can use an asynchronous parallel interface with 70 ns timing. The 128K x 16 organization should match the intended memory map and data width. Board design should account for the 48-FBGA (7x7) surface-mount footprint and the -40°C to 85°C ambient temperature range. When reviewing land patterns and assembly documentation, verify the package designation used for the device, including 48-TFBGA and 48-FBGA (7x7).
