Product details
Overview
S29GL064N90BFI042 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-bit bus), featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It implements uniform sector architecture with 128 × 64 KB sectors and supports both standard and accelerated programming via WP#/ACC input for factory throughput.
For engineers reviewing the S29GL064N90BFI042 datasheet, S29GL064N90BFI042 pinout, S29GL064N90BFI042 application, or S29GL064N90BFI042 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 reset (RESET#) support for boot firmware recovery in embedded systems.
Technical Context
This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole assisted erase and hot-electron injection programming across full sectors. Its VersatileI/O™ control ties all input/output voltage thresholds to VIO (1.65–3.6 V), decoupling I/O logic levels from core VCC (2.7–3.6 V) for mixed-voltage system interfacing.
The architecture integrates dedicated state control logic, command register, and erase/program voltage generators to execute sector erase, chip erase, program suspend/resume, and erase suspend/resume operations autonomously. Status reporting relies on DQ7 polling, DQ6/DQ2 toggle bits, and RY/BY# output - eliminating need for external timing circuits during write cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables storage of full boot code + firmware image in single device |
| Access Time | 90 ns at VCC = 2.7–3.6 V, VIO = 2.7–3.6 V; meets real-time read latency requirements for ARM Cortex-M4/M7 boot fetch |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over 10+ years in industrial controllers |
| Data Retention | 20 years at 85°C; validated for automotive under-hood and telecom base station deployments |
| Page Read Buffer | 8-word (16-byte) buffer; reduces sequential instruction fetch overhead in XIP (execute-in-place) configurations |
| Write Buffer Size | 16-word (32-byte) buffer; cuts multi-word programming time by >40% vs. byte-by-byte writes |
| Supply Voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows direct interface with 1.8 V/3.3 V microcontrollers without level shifters |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package), body size 12 mm × 20 mm, lead pitch 0.5 mm. Pinout conforms to JEDEC MO-142AC standard for 48-pin Flash devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4M-word addressing; A-1 (DQ15) used as MSB in x16 mode |
| DQ0–DQ15 | Data/Address Bus (x16) | Bidirectional 16-bit data bus; DQ15 doubles as A-1 for extended addressing in x16 configuration |
| CE# | Chip Enable | Active-low chip select; device enters standby when CE# high, enabling low-power multi-device bus sharing |
| OE# | Output Enable | Controls output drivers only; allows read data latching while CE# remains asserted for burst reads |
| WE# | Write Enable | Initiates command write, program, or erase cycle; sampled on rising edge of WE# for command latch |
| WP#/ACC | Write Protect / Accelerated Program | Low = hardware sector protection; high + VCC ≥ 3.0 V = accelerated programming (reduces tBP by ~50%) |
| RESET# | Hardware Reset | Asynchronous active-low reset; terminates ongoing erase/program and returns device to read mode within 100 ns |
| RY/BY# | Ready/Busy Output | Open-drain status flag; low = operation in progress, high = ready; drives external interrupt for host polling |
| BYTE# | Bus Width Select | High = x16 mode (DQ0–DQ15 active); low = x8 mode (DQ0–DQ7 only), enabling compatibility with 8-bit hosts |
| VIO | I/O Supply Voltage | Defines logic threshold for all pins except RESET#, RY/BY#, and WP#/ACC; enables mixed-voltage system integration |
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 |
| Advanced Sector Protection | Persistent and Password Sector Protection modes; prevents accidental or unauthorized firmware overwrite in production or field |
| Program/Erase Suspend | Allows host to pause active program/erase in one sector to read/program another; essential for real-time OS firmware updates |
| CFI Compliance | Standardized query table at address 0x0055; enables automatic detection and configuration by BIOS/bootloader without hard-coded parameters |
| Unlock Bypass Mode | Reduces multi-word programming from 4-cycle to 2-cycle command sequence; improves firmware update throughput 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 speed, but 56-pin TSOP package; lacks Secured Silicon Sector and Password Protection features | Targeted at cost-sensitive consumer electronics where secure identity and firmware locking are not required | Select when board layout accommodates larger 56-pin footprint and security features are unnecessary |
| MX29GL640EHTI-90G | 64 Mbit, 90 ns, but uses 130 nm process; lower endurance (10K cycles) and no CFI support; requires custom driver integration | Used in legacy industrial HMIs where firmware update frequency is low and host software stack is fixed | Choose only if existing design already uses Macronix toolchain and long-term endurance is not critical |
Compared with S29GL064S90TFI020, the S29GL064N90BFI042 adds factory-programmed ESN and password protection for secure boot, while versus MX29GL640EHTI-90G it delivers 10× higher endurance and standardized CFI auto-configuration - making it optimal for safety-certified and field-upgradable systems.

FAQ
Does S29GL064N90BFI042 support x8 and x16 data bus widths?
Yes, it supports both configurations via the BYTE# input: when BYTE# is high, the device operates in 16-bit mode using DQ0–DQ15; when low, it functions as an 8-bit device using DQ0–DQ7 only. This flexibility allows seamless integration with 8-bit microcontrollers or 16-bit processors without external glue logic.
What is the function of the WP#/ACC pin in normal operation versus programming mode?
In normal operation, asserting WP# low protects the first or last sector from accidental erase or program. During programming, applying VCC ≥ 3.0 V to WP#/ACC enables accelerated programming mode, reducing byte-program time by up to 50% - a feature intended for high-throughput manufacturing but usable in-field if needed.
How does the Secured Silicon Sector differ from standard sector protection?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region programmed and locked at the factory with a unique 8-word electronic serial number. Unlike software-based sector locks, it cannot be altered after shipment - providing immutable device identity for secure boot, license enforcement, and anti-counterfeiting in certified systems.
Can S29GL064N90BFI042 be used in systems with mixed 1.8 V and 3.3 V logic?
Yes, its VersatileI/O™ architecture separates VIO (1.65–3.6 V) from VCC (2.7–3.6 V), allowing all address, control, and data pins to operate at 1.8 V logic levels while the core runs at 3.3 V. This eliminates external level shifters when interfacing with 1.8 V FPGAs or microcontrollers in battery-powered edge devices.
