SDIN5B2-32G

Memory IC Overview

The SanDisk SDIN5B2-32G is a 32GB Embedded Flash Drive utilizing the e.MMC 4.41 interface and MLC NAND technology. It operates within an industrial temperature range of -25°C to +85°C with core voltage (VCC) between 2.7V and 3.6V, and I/O voltage (VCCQ) at either 1.7-1.95V or 2.7-3.6V. The device supports 1-bit, 4-bit, and 8-bit data bus widths with clock frequencies up to 52 MHz. Sustained read performance reaches 20 MB/s, while sustained write performance is rated at 8 MB/s for X3 configurations.

Memory IC Feature Summary

• Intelligent embedded controller manages wear-leveling, error correction, and defect handling transparently to the host.
• Supports boot partitions, RPMB, and General Purpose Area partitions for flexible memory management.
• Features enhanced reliable write to ensure data integrity during power loss events.
• Includes hardware reset capability and high-priority interrupt support for low-latency operations.

Memory IC Applications

• Mobile handsets and multimedia devices
• Automotive infotainment and navigation systems
• Portable GPS devices

Memory IC Procurement Notes

Verify the specific package dimensions against the datasheet, as the 32GB variant utilizes a 12mm x 18mm footprint with a maximum height of 1.40 mm. Confirm that the host system supports the required VCCQ voltage levels (1.7-1.95V or 2.7-3.6V) and the e.MMC 4.41 protocol. Ensure environmental conditions remain within the specified -25°C to +85°C operating range for reliable performance.

Memory IC Selection Notes

Select this component for applications requiring robust, plug-and-play storage integration without complex host software updates. The device's technology independence allows future firmware upgrades without changing host drivers. Consider the 12x18mm package size for board space constraints and verify compatibility with DDR signaling if higher bus performance is required by the system design.

Memory IC Part Context

This part belongs to the SanDisk iNAND family of Embedded Flash Drives designed for mobile and consumer electronics. It combines an embedded flash controller with standard MLC NAND flash in a JEDEC-compatible form factor. The series is engineered for high reliability and mass storage in portable devices, offering seamless integration through standardized MMC interfaces.

Memory IC Replacement Considerations

Compatible replacements within the same iNAND family include other 32GB e.MMC 4.41 variants such as those with different package sizes (e.g., 14mm x 18mm), provided the pinout and electrical specifications match the host design requirements.

Memory IC FAQ

Does the SDIN5B2-32G support High Priority Interrupt (HPI)?

Yes, the device implements HPI on its MLC products to enable low read latency by suspending lower priority operations.

What is the maximum device height for this specific model?

The maximum device height (A) for the SDIN5B2-32G is 1.40 mm, which differs from the standard 1.20 mm height of smaller capacity variants.
