Product details

Overview

S29GL064N90TFI033 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 S29GL064N90TFI033 datasheet, S29GL064N90TFI033 pinout, S29GL064N90TFI033 application, or S29GL064N90TFI033 equivalent, key selection criteria include JEDEC-compliant command set, CFI interface support, Secured Silicon Sector with factory-programmed 128-word ESN, flexible sector protection modes (Persistent and Password), and dual-voltage I/O control via VIO (1.65–3.6 V).

Technical Context

This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole erase and hot-electron programming across full sectors. Its architecture integrates dedicated erase voltage and program voltage generators, state control logic, and a command register that latches addresses/data internally during write cycles.

The device supports byte/word configuration via BYTE# input, offers Program Suspend/Resume and Erase Suspend/Resume for concurrent operations, and uses DQ7 polling, DQ6 toggle, and RY/BY# output for real-time status monitoring-enabling host systems to read other sectors during active programming or erasure.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4,194,304 × 16-bit words), enabling boot code and firmware storage in resource-constrained embedded systems.
Access Time	90 ns at VCC = 2.7–3.6 V and VIO = 2.7–3.6 V - meets timing requirements for legacy 3.3 V microcontroller interfaces without wait states.
Erase Endurance	100,000 cycles per sector - supports field firmware updates over extended product lifecycles in industrial controllers.
Data Retention	20 years at 125 °C - validated for automotive under-hood and industrial high-temperature applications.
Supply Voltage	Single 3.0 V supply (VCC = 2.7–3.6 V); VIO independently configurable from 1.65–3.6 V - enables mixed-voltage system interfacing (e.g., 1.8 V I/O with 3.3 V core).
Page Read Buffer	8-word (16-byte) buffer with 25 ns page read time - accelerates sequential instruction fetch in boot ROM applications.
Write Buffer	16-word (32-byte) buffer - reduces multi-word programming overhead by batching writes before internal commit.

Pinout & Package

Package: 48-pin TSOP (Type I, standard thin small outline package), 12 × 20 mm body, lead pitch 0.5 mm. Pinout conforms to JEDEC MO-141AC standard for 48-pin Flash devices.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4 Mword addressing; A-1 (DQ15) used as MSB in x16 mode.
DQ0–DQ15	Data I/O Bus	16-bit bidirectional data path; functions as 8-bit bus when BYTE# = low (x8 mode).
CE#	Chip Enable	Active-low chip select; device enters standby when CE# high, enabling power gating in multi-device systems.
OE#	Output Enable	Active-low read strobe; controls output drivers only - does not affect internal state or power mode.
WE#	Write Enable	Active-low signal initiating command latching, programming, or erase - synchronized with address/data setup/hold timing.
WP#/ACC	Write Protect / Accelerated Program	Logic low enables hardware sector protection (first/last sector); high-voltage input accelerates programming for production throughput.
RY/BY#	Ready/Busy Output	Open-drain active-low status flag indicating ongoing program/erase - eliminates need for software polling in time-critical systems.
RESET#	Hardware Reset	Asynchronous active-low reset terminating all operations and returning device to read mode - synchronizes boot sequence with system reset.
VIO	I/O Supply Voltage	Independent voltage reference for all input thresholds and output drive levels - decouples I/O logic from core VCC for mixed-signal compatibility.

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory-locked region with 8-word electronic serial number - provides immutable device identity for secure boot and anti-cloning.
Advanced Sector Protection	Persistent Sector Protection (non-volatile lock bits) and Password Sector Protection (16-byte password required) - prevents unauthorized firmware modification in deployed systems.
CFI Compliance	Common Flash Interface v1.3 implementation - enables automatic device detection, parameter querying, and vendor-agnostic driver integration in BIOS/bootloader stacks.
Unlock Bypass Mode	Two-cycle command sequence replaces four-cycle standard programming - cuts multi-word write latency by ~50% in high-volume manufacturing test.
Erase Suspend/Resume	Pause erase in one sector to read/program another - allows background firmware update while maintaining real-time interrupt response in safety-critical applications.

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 64 Mbit density and 90 ns speed, but uses 56-pin TSOP package and lacks Secured Silicon Sector.	Targeted at cost-sensitive industrial HMI where device identity and secure boot are not required.	Select when board layout accommodates larger 56-pin footprint and security features are unnecessary.
MX29GL640EHT2I-90G	64 Mbit, 90 ns, 48-pin TSOP, but uses Macronix's MX29GL architecture with different CFI query structure and no Password Sector Protection.	Used in legacy telecom baseband modules where JEDEC command compatibility is sufficient but advanced protection is unused.	Choose only if existing driver stack already supports MX29GL-specific CFI offsets and unlock sequences.

Compared with S29GL064S90TFI020 and MX29GL640EHT2I-90G, the S29GL064N90TFI033 uniquely delivers factory-programmed ESN, dual-sector protection modes, and VIO-controlled I/O flexibility - making it the sole option for designs requiring certified secure boot and mixed-voltage interoperability.

FAQ

What is the function of the VIO pin on S29GL064N90TFI033?

The VIO pin sets the voltage reference for all input thresholds and output drive levels. It operates independently from VCC and accepts 1.65–3.6 V, allowing the device to interface directly with 1.8 V or 2.5 V microcontrollers while maintaining full 3.0 V core functionality - eliminating level shifters in mixed-voltage designs.

Does S29GL064N90TFI033 support true 8-bit data bus operation?

Yes. When the BYTE# pin is driven low, the device operates in x8 mode: DQ0–DQ7 become the data bus, and DQ8–DQ15 are tri-stated. Address lines remain unchanged, and all commands function identically - enabling backward compatibility with 8-bit microprocessor buses without redesigning PCB traces.

How is the Secured Silicon Sector protected after factory programming?

The Secured Silicon Sector is permanently locked via fuse-based protection. Once programmed and locked - either at factory or by customer using the Lock Register command - no further writes or erases are possible, even with valid passwords or ACC voltage. The 8-word ESN remains readable but immutable, providing cryptographically verifiable device identity.

Can S29GL064N90TFI033 be used in systems requiring -40°C to +105°C operation?

No. This part is specified for industrial temperature range (-40°C to +85°C) only. While 20-year data retention is validated at 125°C, operational functionality is not guaranteed above +85°C. For extended temperature applications, Infineon offers the S29GL064N11TFI020 variant rated to +105°C with identical pinout and command set.
