What is the Kioxia TC58BVG1S3HTAI0B4H?

It is a 2 Gbit, 3.3V SLC NAND Flash memory from Kioxia's BENAND family. It uses an x8 interface (256M x 8), integrates on-chip ECC, and is rated for the industrial -40 to +85C temperature range in a 48-pin TSOP I package.

What does BENAND mean and why does it matter?

BENAND is Kioxia's SLC NAND with a built-in Error Correction Code engine. Per the datasheet it corrects 8-bit errors for each 528 bytes on-chip and supports ECC Status Read, so the host controller does not need its own external ECC logic. This simplifies designs and eases migration from raw NAND or NOR Flash.

What is the difference between TC58BVG1S3 (B) and TC58NVG1S3 (N) parts?

The BVG (B) version is a BENAND device with on-chip ECC, while the NVG (N) version is raw NAND that requires host-side ECC and provides a larger spare area. Both are 2Gb, 3.3V, x8, 48-TSOP parts, but they are not drop-in replacements without firmware/ECC changes.

Is the TC58BVG1S3HTAI0B4H still in production?

No. Authorized distributors list this device as obsolete/end-of-life, with last-time-buy and last-time-ship deadlines and limited availability. Pacific Component Xchange stocks and sources it to support ongoing production and repair needs.

What does the trailing B4H mean in the part number?

The core Kioxia device is TC58BVG1S3HTAI0; the trailing B4H reflects a specific packing or handling configuration. The underlying silicon, density, voltage, interface, ECC, and temperature rating are the same as the base part.

TC58BVG1S3HTAI0B4H – SLC NAND Flash – Kioxia

The Kioxia TC58BVG1S3HTAI0B4H is a 2 Gbit, 3.3V SLC NAND Flash memory from the BENAND family, featuring on-chip ECC, an x8 interface, and an industrial-grade -40 to +85°C operating range in a 48-pin TSOP I package.

The Kioxia TC58BVG1S3HTAI0B4H is a 2 Gbit (256M x 8) Single-Level Cell (SLC) NAND Flash memory belonging to Kioxia’s BENAND™ family. BENAND devices integrate an on-chip Error Correction Code (ECC) engine that internally corrects 8-bit read errors for each 528 bytes of data, so the host system does not need to implement an external ECC controller. This makes the part well suited to designs migrating from older raw NAND or NOR Flash where adding host-side ECC would be costly. The device originates from the Toshiba TC58BVG1S3 architecture and is now offered under the Kioxia brand.

The TC58BVG1S3HTAI0B4H operates from a single 3.3V supply (2.7V–3.6V). The “I” grade in the part number denotes the industrial temperature variant, rated for the -40 to +85°C operating range, making it suitable for demanding embedded and industrial environments. The trailing B4H designator reflects a specific packing/handling configuration of the base Kioxia device TC58BVG1S3HTAI0. Note: the linked Kioxia datasheet (TC58BVG1S3HTA00) is the authoritative electrical/timing document for this die; the HTA00 sibling shares identical density, organization, voltage, interface, ECC, and timing, differing only in temperature grade.
