STMicroelectronics NAND01GW3A2AN6E

Overview

NAND01GW3A2AN6E from STMicroelectronics is a 1 Gbit, x8-bus-width NAND Flash memory with 2112-byte pages (2048 + 64 spare), 128 KiB blocks (128K + 4K spare), and 1.8 V supply (VDD = 1.7–1.95 V). It supports Cache Read/Program, Copy Back Program, and hardware/software block locking, and is packaged in a 48-pin TSOP48 (12 × 20 mm) for embedded mass storage in portable electronics and industrial controllers.

For engineers reviewing the NAND01GW3A2AN6E datasheet, NAND01GW3A2AN6E pinout, NAND01GW3A2AN6E application, or NAND01GW3A2AN6E equivalent, key selection criteria include page read timing (25 µs max random access), block erase endurance (100,000 cycles), spare area size (64 bytes/page), Ready/Busy open-drain signaling, and ECOPACK® lead-free compliance.

Technical Context

This device implements a multiplexed x8 I/O bus where address and data share the same pins (I/O0–I/O7), reducing footprint while enabling density migration across the NAND01G-B/NAND02G-B family. Its P/E/R controller manages all internal operations-including Page Read, Cache Read, Page Program, Cache Program, Copy Back Program, and Block Erase-without external microcontroller intervention during execution.

The status register (SR) provides real-time operational feedback: SR6 indicates P/E/R controller busy state, SR7 reflects write protection status, and SR0/SR1 flag program/erase errors. The Chip Enable 'don't care' feature allows uninterrupted reads even during CE transitions, simplifying interface timing with resource-constrained microcontrollers.

FAQ

What is the maximum clock frequency supported for the NAND01GW3A2AN6E interface?

The NAND01GW3A2AN6E does not use a clock signal; it operates asynchronously using control strobes (R, W, AL, CL). Its timing is governed by AC parameters: minimum tRC (read cycle time) is 25 ns, implying an effective maximum sustained interface rate of ~40 MHz for sequential operations. Random access is limited by tR (25 µs), not clock frequency.

Does NAND01GW3A2AN6E require external ECC hardware or can it operate with software-only correction?

NAND01GW3A2AN6E has no built-in ECC engine. It relies on external hardware (e.g., SoC NAND controller with BCH-4-bit support) or host-side software ECC. The 64-byte spare area per page is sized to store ECC parity data - typically 24 bytes for BCH-4-bit correction covering 2048 data bytes - making software-only correction feasible but computationally intensive.

How is block locking implemented, and can it be overridden in-system?

Block locking is implemented via status register bits and dedicated commands (1Fh unlock, 2Fh lock-down). Hardware locking persists through power cycles and cannot be overridden without issuing explicit unlock commands. Lock-down mode permanently disables further lock/unlock operations until power-cycled, preventing accidental changes during field updates.

Is the TSOP48 package of NAND01GW3A2AN6E compatible with industry-standard socket footprints?

Yes - the TSOP48 package (12 × 20 mm, 0.5 mm pitch, 48-pin) conforms to JEDEC MO-142AC standard. Its pinout matches common NAND Flash TSOP48 footprints used in reference designs from NXP, Renesas, and Microchip, enabling direct replacement without layout modification in most existing 1.8 V NAND-based systems.
