CY7C1049GN30-10VXI

Memory IC Overview

The CY7C1049GN30-10VXI is a 4-Mbit (512K words × 8-bit) static RAM manufactured by Infineon Technologies. It features a 10 ns access time and operates within a voltage range of 2.2 V to 3.6 V. The device utilizes a parallel interface with TTL-compatible inputs and outputs, housed in a Pb-free 36-pin Molded SOJ package. Typical active current is 38 mA, while standby current is 6 mA. It supports data retention at 1.0 V and functions across an industrial temperature range of -40 °C to +85 °C.

Memory IC Feature Summary

• Supports low-power operation with typical active current of 38 mA and standby current of 6 mA.
• Features TTL-compatible inputs and outputs for broad logic compatibility.
• Maintains data integrity during power loss via 1.0 V data retention capability.

Memory IC Applications

• Industrial embedded systems requiring volatile memory storage
• High-speed data buffering in consumer electronics
• Cache memory applications in microcontroller-based designs

Memory IC Procurement Notes

Verify the specific ordering suffix 'VXI' corresponds to the 36-pin Molded SOJ package configuration. Confirm that the '30' designation matches the required 2.2 V to 3.6 V operating voltage range for your system design. Ensure compliance with RoHS standards as indicated by the Pb-free construction. Cross-reference the datasheet revision history to confirm the document version aligns with your manufacturing requirements.

Memory IC Selection Notes

Select this component when a 4-Mbit capacity with 10 ns speed is required within a 2.2 V to 3.6 V supply environment. The 36-pin SOJ package suits surface-mount assembly processes. Consider the 1.0 V data retention feature if battery-backed or low-voltage hold states are necessary. Verify that the industrial temperature grade (-40 °C to +85 °C) meets the operational environmental constraints of the target application.

Memory IC Part Context

This part belongs to the CY7C1049GN family of high-performance CMOS fast static RAM devices. The family offers multiple voltage options, including 1.65 V–2.2 V and 4.5 V–5.5 V ranges, alongside varying speed grades. The GN suffix indicates 65 nm process technology. The product portfolio includes both TSOP II and SOJ package options to accommodate different board layout densities and assembly preferences.

Memory IC Replacement Considerations

CY7C1049GN30-10ZSXI: Offers identical electrical specifications but utilizes a 44-pin TSOP II package instead of the 36-pin SOJ. Requires PCB footprint modification.

Memory IC FAQ

What is the minimum voltage required to retain stored data?

The device supports data retention down to 1.0 V.

How does the Chip Enable signal affect output impedance?

When CE is HIGH, the I/O lines enter a high-impedance state, effectively deselecting the device.
