S34ML08G101TFA000

A: The S34ML08G101TFA000 is optimized for high‑performance, low‑power embedded applications. The table below summarises its core specifications, drawn directly from manufacturer data and multiple distributor sources: Specification Value Memory Density 8 Gbit (1 GB) Memory Organization 1G × 8 bits Cell Type SLC NAND (Single‑Level Cell) Interface Parallel asynchronous / 8‑bit I/O Supply Voltage (VCC) 2.7V to 3.6V Operating Temperature –40°C to +85°C (industrial grade) Automotive Qualification AEC‑Q100 (automotive‑grade) Access Time (tRC) 25 ns (page read access) Page Program Time (tPROG) 200 µs (typical) Block Erase Time (tBERS) 3.5 ms (typical) Write Cycle Time 25 ns (word/page) Active Read Current 30 mA Supply Current (Max) 35 mA ECC Requirement 1‑bit ECC (Error Correction Code) per 528 bytes Package Type 48‑pin TSOP‑I (TSOP1‑48) Package Dimensions 18.4 mm (length) × 12.0 mm (width)×11†L35-L36】 Mounting Type Surface mount

A: The S34ML08G101TFA000 uses a parallel asynchronous interface with an 8‑bit wide data bus (I/O0–I/O7). Communication with the host processor is controlled via a standard set of NAND Flash command signals including: CLE (Command Latch Enable): Distinguishes a command from data. ALE (Address Latch Enable): Distinguishes an address from data. CE# (Chip Enable): Selects the device. RE# (Read Enable): Enables serial data output. WE# (Write Enable): Enables serial data input. WP# (Write Protect): Provides hardware protection during power transitions. R/B# (Ready/Busy): Indicates the status of program and erase operations. The device supports a 512‑byte page size plus a 16‑byte spare area per page (total 528 bytes), organised into blocks of 64 pages, with each block therefore offering 32 Kb of raw storage. The I/O width is fixed at 8 bits (x8). The device requires the host to manage 1‑bit Error Correction Code (ECC) per 528 bytes to detect and correct single‑bit errors that may naturally occur in NAND Flash over the device’s lifetime. This is a critical responsibility of the host microcontroller or memory controller.

A: The S34ML08G101TFA000 is engineered for long‑term reliability. The table below outlines its key reliability specifications: Reliability Parameter Specification Write Endurance Typical 60,000 to 100,000 program/erase cycles (per block) Data Retention 10 years (minimum) Operating Temperature –40°C to +85°C (industrial grade) Page Program Time 200 µs (typ) Block Erase Time 3.5 ms (typ) Additionally, the device includes on‑chip ECC capable of correcting 1‑bit errors per 528 bytes, which is the industry‑standard baseline requirement for SLC NAND Flash memory. Important Note: For mission‑critical applications, software ECC implementation is still required in the host controller to meet the full endurance and data retention specifications. The device's AEC‑Q100 qualification ensures it meets the stringent reliability and quality standards required for automotive applications.

A: Thanks to its 8 Gbit density, high reliability (SLC NAND), industrial temperature rating (–40°C to +85°C), and AEC‑Q100 automotive qualification, the S34ML08G101TFA000 is well‑suited for a broad range of embedded applications. Typical use cases include: Automotive electronics – Engine control units (ECUs), body control modules, infotainment and navigation systems, ADAS (Advanced Driver Assistance Systems) Industrial automation – Programmable logic controllers (PLCs), data loggers, factory automation equipment, HMIs Telecommunications and networking – Routers, switches, base station equipment Aerospace and defence – Ruggedised storage for mission‑critical systems Embedded systems – Firmware storage, boot code storage, configuration parameters in high‑reliability equipment ⚠️ Important Lifecycle Information: The product lifecycle status of the S34ML08G101TFA000 is contradictory across multiple authoritative distributor databases. Some sources list the part status as Obsolete, others as Active, and others as Not Recommended for New Designs (NRND). Mouser lists the part with the explicit note “Suggested Alternate S34ML08G301TFA000” and indicates the product is no longer manufactured. Both DigiKey and Unikeyic also show the part as Obsolete, while Bonchip lists the part status as Active and Worldway also lists it as Active. The authorised manufacturer (SkyHigh Memory) recommends the S34ML08G301TFA000 as the direct suggested replacement for the S34ML08G101TFA000. Given this conflicting lifecycle information, engineers are strongly advised to verify current lifecycle status, availability, and lead times directly with an authorised distributor before committing this part to a new design. For new projects, the S34ML08G301TFA000 is the recommended replacement part from the manufacturer, offering the same 8 Gbit density and SLC NAND technology with ongoing active production status.
