Product details

Overview

S29GL064N90TAI040 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words × 16 bits, featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It supports uniform sector architecture with 128 × 64 KB sectors and operates across VIO = 1.65–3.6 V for flexible I/O voltage control - deployed in industrial control firmware storage and boot code retention.

For engineers reviewing the S29GL064N90TAI040 datasheet, S29GL064N90TAI040 pinout, S29GL064N90TAI040 application, or S29GL064N90TAI040 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-configuration, and hardware write protection via WP#/ACC input.

Technical Context

This device implements a 110 nm MirrorBit floating-gate NAND-like cell architecture enabling simultaneous hot-hole erase and hot-electron programming within discrete sectors. Its VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), allowing interoperability with 1.8 V or 3.3 V logic domains while maintaining full 16-bit bus operation.

The command-based interface supports program/erase suspend-resume, unlock bypass mode (2-cycle programming), and persistent/password sector protection - all executed via standard microprocessor write timing without external high-voltage generators. Sector erase granularity and CFI descriptor tables enable runtime flash topology discovery by host firmware.

Key Specifications

DQ0–DQ15	Data I/O	16-bit bidirectional data bus; DQ15 doubles as A-1 for x16 addressing; supports BYTE#-controlled x8/x16 mode
CE#, OE#, WE#	Chip/Output/Write Enable	Independent active-low controls allow interleaved read/write operations and partial memory mapping
WP#/ACC	Write Protect / Accelerated Program	Logic-low asserts hardware sector lock; high-voltage pulse enables faster factory programming throughput
RY/BY#	Ready/Busy Output	Open-drain status signal indicating active erase/program cycle completion - critical for interrupt-driven firmware
RESET#	Hardware Reset	Asynchronous reset terminates ongoing operations and restores device to known state for safe boot recovery

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory-locked region with 8-word ESN - provides immutable device identity for secure boot and licensing
Password Sector Protection	128-bit password required before modifying protected sectors - prevents unauthorized firmware tampering in field-deployed units
Erase Suspend/Resume	Pause background erase to service urgent reads/writes in other sectors - essential for real-time OS coexistence
CFI Compliance	Standardized query table at address 0x0055 allows host to auto-detect geometry, timing, and protection features without hard-coded assumptions
Unlock Bypass Mode	Reduces multi-word programming overhead from 4 to 2 write cycles - improves firmware update speed by ~33%

Equivalent & Alternatives

The following parts are listed as comparable options for similar Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90TFI020	Same density and timing, but 56-pin TSOP package and VIO = 2.7–3.6 V only - no 1.65 V support	Lacks low-VIO flexibility; unsuitable for mixed-voltage SoC interfaces	Select when board layout requires larger TSOP footprint and system uses only 3.3 V I/O
MX29GL640EHT2I-90G	64 Mbit, 90 ns, but uses 1.8 V core + 3.3 V I/O; different command set and no Secured Silicon Sector	No factory-programmed ESN or password protection - limits secure boot capability	Choose for cost-sensitive consumer applications where security features are not required

Compared with S29GL064S90TFI020 and MX29GL640EHT2I-90G, the S29GL064N90TAI040 uniquely combines 1.65 V I/O compatibility, Secured Silicon Sector, and JEDEC command consistency - making it the only option for secure, mixed-voltage industrial firmware storage.

FAQ

What is the function of the WP#/ACC pin on S29GL064N90TAI040?

The WP#/ACC pin serves dual functions: when held low, it hardware-protects the first or last sector against accidental erase or program; when pulsed to VCC + 0.5 V (up to 3.9 V), it enables accelerated programming for higher factory throughput. This dual-mode operation is confirmed in the datasheet's Section 8.16 and requires no external circuitry beyond a pull-down resistor and optional voltage booster.

Does S29GL064N90TAI040 support both x8 and x16 data bus widths?

Yes - the device supports configurable bus width via the BYTE# input: asserted low selects x16 mode (DQ0–DQ15 active); asserted high enables x8 mode (DQ0–DQ7 only), with DQ15 functioning as A-1. This is explicitly defined in Section 8.1 and verified in the connection diagram for 48-pin TSOP (Figure 1).

How is the Secured Silicon Sector programmed and locked?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed at the factory with a unique 8-word (16-byte) Electronic Serial Number. It can be permanently locked using the Persistent Sector Protection command sequence (Section 8.11), after which no further writes or erases are possible - even with valid passwords or ACC voltage.

Is CFI (Common Flash Interface) fully implemented in this device?

Yes - the device implements full JEDEC JESD68-A CFI specification, including standardized query identification string at address 0x0055, geometry descriptors, and command set tables. Host systems use this to auto-detect sector map, timing parameters, and protection features without vendor-specific drivers.
