Product details
Overview
S29GL064N90BAI043 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 VCC = 2.7–3.6 V and VIO = 1.65–3.6 V - deployed in industrial control firmware storage and boot code retention systems.
For engineers reviewing the S29GL064N90BAI043 datasheet, S29GL064N90BAI043 pinout, S29GL064N90BAI043 application, or S29GL064N90BAI043 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent + Password), Erase/Program Suspend & Resume, and CFI compliance for host system auto-configuration.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NOR Flash architecture with hot-hole assisted erase and hot-electron injection programming. It features dual-voltage I/O control via VIO (1.65–3.6 V), independent CE#/OE#/WE# controls, and hardware reset (RESET#) for boot recovery.
The memory array is partitioned into uniform 64 KB sectors (128 total), each erasable independently. Status reporting uses DQ7 Data# Polling, DQ6/DQ2 toggle bits, and RY/BY# output - all fully compliant with JEDEC Standard JESD21-C for single-power flash devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables full boot image + configuration storage in single device |
| Access Time | 90 ns at VCC = 2.7–3.6 V; meets real-time firmware fetch timing in microcontroller-based systems |

| VIO Range | 1.65–3.6 V; allows direct interface to 1.8 V or 3.3 V logic without level shifters |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package), lead pitch 0.5 mm, body size 12 × 20 mm - RoHS-compliant, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| DQ0–DQ15 | Data I/O (x16) | Bidirectional 16-bit data bus; BYTE# input enables x8 mode by masking upper/lower byte |
| CE# | Chip Enable | Active-low chip select; device enters standby when deasserted, reducing current to 1 µA |
| OE# | Output Enable | Active-low output control; enables data output only during valid read cycles |
| WE# | Write Enable | Active-low write strobe; latches addresses/data for command execution and programming |
| WP#/ACC | Write Protect / Accelerated Program | Low = hardware sector protection; high + VHH = accelerated programming (factory throughput mode) |
| RY/BY# | Ready/Busy Output | Open-drain active-low status signal; indicates ongoing erase/program operation completion |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates any operation and restores device to read mode |
| VIO | I/O Supply Voltage | Separate voltage rail for input thresholds and output drive; decouples logic interface from core VCC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI010 | Same density and 90 ns speed, but 56-pin TSOP package and VIO = 2.7–3.6 V only; no 1.65 V low-VIO support | Lacks flexible I/O voltage range; unsuitable for mixed-voltage SoC interfaces requiring 1.8 V signaling | Select when board layout accommodates larger 56-pin footprint and system uses only 3.3 V I/O |
| MX29GL640EHTI-90G | 64 Mbit, 90 ns, but uses Macronix's MXSMIO command set; not JEDEC CFI-compliant; different unlock sequence | Requires custom driver porting; no automatic CFI enumeration in standard BSPs | Choose only if existing design already uses MX29GL family and firmware stack is adapted |
Compared with S29GL064S90TFI010, this part offers broader I/O voltage flexibility and smaller 48-pin footprint; versus MX29GL640EHTI-90G, it delivers plug-and-play CFI compatibility and standardized command set - critical for rapid BSP integration and long-term maintainability.

FAQ
Is S29GL064N90BAI043 pin-compatible with earlier S29GL064N variants?
Yes - the 'AI043' suffix denotes a 48-pin TSOP package with industrial temperature range (–40°C to +85°C) and same pinout as other S29GL064N 48-pin variants. Pin functions, spacing, and mechanical dimensions match TS048 specification per datasheet Figure 1. No PCB redesign is required when migrating from AI010 or AI020 versions.
Does this device support x8 data bus mode?
Yes - the BYTE# input enables x8 mode: when asserted low, DQ0–DQ7 become active data lines while DQ8–DQ15 are tri-stated. This is confirmed in Section 8.1 (Word/Byte Configuration) of the datasheet and supported across all operating voltages and timing modes.
What is the purpose of the WP#/ACC pin in accelerated programming mode?
When WP#/ACC is driven high and VHH (~11.5 V) is applied to ACC, internal programming voltage generation is boosted, reducing typical program time per word by ~35%. This mode is intended for high-throughput factory programming and is disabled during normal system operation unless explicitly enabled.
How is the Secured Silicon Sector protected after factory programming?
The Secured Silicon Sector is permanently locked using a one-time-programmable fuse. Once secured, no command - including chip erase - can modify its contents. Access requires a specific unlock sequence (0x00AA, 0x0055, 0x00F0), and the 8-word ESN remains readable but unwritable even under accelerated programming conditions.
