Product details

Overview

S29GL064N11TAIV20 from Cypress Semiconductor is a 64 Mbit (8 MB), 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 × 16-bit words, featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It supports uniform or boot-sector architecture with 128 × 64 KB sectors or 127 × 64 KB + 8 × 8 KB boot sectors, and is used in embedded boot code storage for industrial controllers and network edge devices.

For engineers reviewing the S29GL064N11TAIV20 datasheet, S29GL064N11TAIV20 pinout, S29GL064N11TAIV20 application, or S29GL064N11TAIV20 equivalent, key selection factors include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-configuration, and hardware reset (RESET#) and ready/busy (RY/BY#) signaling for reliable system boot sequencing.

Technical Context

This device implements a 16-bit parallel NOR Flash interface with separate CE#, OE#, and WE# controls, enabling true random-access read and page-based programming. Its 110 nm MirrorBit process enables hot-electron injection programming and hot-hole assisted erase, supporting both uniform and boot-sector erase configurations.

The architecture includes dedicated hardware features: WP#/ACC input for accelerated programming and first/last sector protection, RY/BY# output for cycle completion detection, and RESET# for immediate operation termination and device initialization - all critical for deterministic boot firmware execution in safety-aware systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4,194,304 × 16-bit words / 8,388,608 bytes)
Supply Voltage (VCC)	2.7–3.6 V - single supply powers both read and program/erase operations
Access Time	90 ns - determines minimum CPU wait-state timing for direct memory-mapped boot code fetch
Erase Endurance	100,000 cycles per sector - supports field firmware updates over product lifetime
Data Retention	20 years at 125°C - ensures long-term reliability in industrial temperature environments
Page Read Buffer	8-word (16-byte) - reduces sequential read latency in burst-access scenarios
Write Buffer Size	16-word (32-byte) - cuts multi-word programming time by minimizing command overhead
CFI Compliance	Yes - enables host system to auto-detect device geometry, timing, and command set via standardized query

Pinout & Package

Package: 48-pin TSOP (Type I, standard thin small outline package), 12 × 20 mm body, lead pitch 0.5 mm.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4M-word addressing; A-1 (DQ15/A-1) enables byte/word mode selection
DQ0–DQ15	Data/Address Multiplexed I/O	16-bit bidirectional data bus; DQ15 doubles as A-1 for byte-mode configuration when BYTE# = low
CE#	Chip Enable	Active-low chip select - must be asserted for any internal operation; enables power-down in standby mode
OE#	Output Enable	Active-low control for data bus drivers - decouples read data without disabling chip
WE#	Write Enable	Active-low strobe for latching commands, addresses, and data during program/erase sequences
RESET#	Hardware Reset	Active-low asynchronous reset - terminates ongoing erase/program and returns device to read mode
RY/BY#	Ready/Busy Output	Open-drain status signal - low during active program/erase, high when operation complete or in read mode
WP#/ACC	Write Protect / Accelerated Program	Input that protects first/last sector when low; enables faster programming when driven to VHH (~6.5 V) in production
BYTE#	Bus Width Select	Low = 8-bit data mode (DQ0–DQ7 only); high = full 16-bit mode - configures interface for host bus width

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory- or customer-lockable region with 8-word ESN - provides immutable device identity for secure boot verification
Advanced Sector Protection	Persistent and Password Sector Protection modes - prevent unauthorized firmware modification without hardware reset or password entry
Program/Erase Suspend	Allows host to pause programming or erasing one sector to read/program another - essential for real-time interrupt handling during firmware update
VIO Flexibility	VIO input (1.65–3.6 V) sets all I/O voltage thresholds - enables interoperability with mixed-voltage host systems (e.g., 1.8 V core + 3.3 V I/O)
Unlock Bypass Mode	Reduces multi-word programming from 4 to 2 write cycles - improves throughput in manufacturing and field update scenarios

Equivalent & Alternatives

The following parts are listed as comparable options for similar NOR Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S11TFIV20	Same density and timing, but 56-pin TSOP package and VIO range extended to 1.65–3.6 V (vs. 2.7–3.6 V on S29GL064N)	Supports lower-voltage I/O interfaces (e.g., 1.8 V microcontrollers); requires PCB redesign for 56-pin footprint	Select when host I/O voltage is <2.7 V or board layout accommodates larger TSOP
MX29GL640EHTI-90G	64 Mbit, 90 ns, but uses Macronix's MX29GL architecture; lacks Secured Silicon Sector and CFI v1.4 support	No factory-programmed ESN or password protection - unsuitable for secure boot or device authentication use cases	Select only for cost-sensitive, non-security applications where JEDEC command compatibility suffices

Compared with S29GL064S11TFIV20, the S29GL064N11TAIV20 offers tighter VIO tolerance and smaller 48-pin TSOP footprint, while MX29GL640EHTI-90G trades security and configurability for lower unit cost - making the S29GL064N optimal for space-constrained, security-aware embedded boot designs.

FAQ

What is the function of the WP#/ACC pin on S29GL064N11TAIV20?

The WP#/ACC pin serves dual roles: when held low, it hardware-protects the first or last memory sector against accidental program/erase; when driven to ~6.5 V (VHH), it enables accelerated programming for higher throughput in manufacturing. Its behavior is independent of software sector protection settings and remains active during all device states.

Does S29GL064N11TAIV20 support 8-bit data bus operation?

Yes - when the BYTE# pin is driven low, the device operates in 8-bit mode using only DQ0–DQ7, with DQ15 functioning as A-1 address bit. This allows seamless integration with 8-bit microcontrollers or legacy bus architectures without external data-width translation logic.

How does the Secured Silicon Sector differ from standard flash sectors?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed with a unique 8-word Electronic Serial Number (ESN) and permanently locked via fuse or command. Once secured, no further writes or erases are possible - unlike standard sectors, it cannot be unlocked or reconfigured, providing immutable device identity for secure boot chains.

Can S29GL064N11TAIV20 be used in place of older S29GL064N variants with different speed grades?

Yes - the '11' speed grade (90 ns access) is backward-compatible with slower variants (e.g., '12' = 110 ns) in read operations, but timing-critical systems must verify setup/hold margins for WE#/OE#/CE# signals. Programming and erase times remain identical across speed grades, as they depend on internal charge-pump operation, not access timing.
