TC58NVG2S0HTAI0B4H – SLC NAND Flash – Kioxia

The TC58NVG2S0HTAI0B4H is a Kioxia (formerly Toshiba) 4 Gbit (512M x 8) parallel SLC NAND Flash memory in a 48-pin TSOP I package, rated for the industrial temperature range of -40°C to +85°C.

The TC58NVG2S0HTAI0B4H is a 4 Gbit single-level-cell (SLC) NAND Flash memory device originally developed by Toshiba and now branded under Kioxia, following the 2019 spin-off of Toshiba Memory Corporation. Part of the proven TC58NVG2S0 family, it provides reliable non-volatile storage organized as 512M x 8 bits and is delivered in an industry-standard 48-pin TSOP I package. The "AI" designation indicates the industrial temperature grade (-40°C to +85°C), making this device well suited for embedded, networking, and industrial designs that demand robust operation across a wide thermal envelope.

This device uses a conventional parallel (x8) NAND interface in which the I/O pins carry commands, addresses, and data. Program and erase operations are automatically executed on-chip, simplifying controller design for code shadowing, firmware storage, and data logging applications.
