CY62177G30-55ZXI

Memory IC Overview

The CY62177G30-55ZXI is a 32-Mbit (2M words × 16-bit) asynchronous static RAM from the MoBL SRAM family. It features embedded error-correcting code for single-bit error correction and operates within a voltage range of 2.2 V to 3.6 V. The device provides a typical standby current of 3 µA and a maximum of 19 µA, with a speed grade of 55 ns. It utilizes TTL-compatible inputs and outputs and includes a byte power-down feature. The component is housed in a 48-pin TSOP I package and supports industrial operating temperatures from -40 °C to +85 °C.

Memory IC Feature Summary

• Embedded ECC circuitry for automatic single-bit error detection and correction
• Ultra-low standby current consumption with byte power-down capability
• TTL-compatible logic levels for simplified system interfacing
• Configurable memory organization supporting 2M x 16 or 4M x 8 modes

Memory IC Applications

• Industrial control systems requiring high reliability
• Battery-backed static random access memory solutions
• Data logging applications in harsh environments
• Automotive electronic control units

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm whether the ERR pin functionality is necessary for the design, as this variant lacks the dedicated error indication output found in the GE30 series. Ensure compatibility with the 2.2 V to 3.6 V supply voltage range during procurement planning.

Memory IC Selection Notes

Select this part when a 32-Mbit capacity with 16-bit width is required alongside data integrity protection. The absence of an ERR pin distinguishes it from the GE30 version; choose this model if error signaling is handled externally or is unnecessary. Verify that the 55 ns access time meets the system timing requirements before finalizing the selection.

Memory IC Part Context

This component belongs to the Infineon MoBL SRAM family, designed for low-power applications. It succeeds previous Cypress Semiconductor designs under the same specifications. The device offers long-term availability commitments suitable for industrial and automotive sectors where extended production lifecycles are critical.

Memory IC Replacement Considerations

Direct replacements include other CY62177G30 variants with different packages, such as CY62177G30-55BKXI for VFBGA. For designs requiring the ERR pin, the CY62177GE30-55ZXI serves as the functional equivalent with added error indication capabilities.
