CY62148DV30LL-55SXI

Memory IC Overview

The CY62148DV30LL-55SXI is a 4-Mbit (512 K × 8) asynchronous static RAM from the MoBL SRAM family. It operates within a voltage range of 2.2 V to 3.6 V and features a 55 ns access time. The device utilizes a 32-pin SOIC package and supports an industrial temperature range of –40 °C to +85 °C.

Memory IC Feature Summary

• Ultra-low active power consumption with typical current of 1.5 mA at 1 MHz operation
• Automatic power-down mode when deselected to reduce standby power
• Pin-compatible with legacy CY62148CV25, CY62148CV30, and CY62148CV33 devices

Memory IC Applications

• Portable cellular telephones
• Battery-powered handheld devices
• Industrial control systems requiring low power memory

Memory IC Procurement Notes

Verify the specific ordering suffix 'SXI' corresponds to the 32-pin SOIC Pb-free package configuration. Confirm that the Industrial temperature grade meets the operational requirements for the target environment. Ensure compatibility with existing system voltage rails within the specified 2.2 V to 3.6 V range before finalizing procurement.

Memory IC Selection Notes

Select this component for designs prioritizing extended battery life in portable electronics due to its ultra-low active and standby power characteristics. It serves as a direct drop-in replacement for older Cypress CY62148 variants, facilitating easier migration to lower voltage architectures without redesigning the physical footprint or pinout.

Memory IC Part Context

This part belongs to the MoBL (More Battery Life) SRAM family, designed specifically for applications where power efficiency is critical. The CY62148 series offers high-density storage in a compact form factor, balancing performance with energy conservation for mobile and industrial sectors.

Memory IC Replacement Considerations

Direct pin-compatible substitutes include CY62148CV25, CY62148CV30, and CY62148CV33. Verify voltage tolerance differences when replacing higher-voltage legacy parts with this 3V-typical device.
