Product details

Overview

S29GL064N90DAI033 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory IC 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 (128 × 64 KB sectors), operates with VIO from 1.65–3.6 V, and is used for embedded boot code storage in industrial controllers and network edge devices.

For engineers reviewing the S29GL064N90DAI033 datasheet, S29GL064N90DAI033 pinout, S29GL064N90DAI033 application, or S29GL064N90DAI033 equivalent, key selection criteria include JEDEC software compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, hardware reset (RESET#), Ready/Busy# status signaling, and flexible sector protection modes including Password and Persistent Sector Protection.

Technical Context

This device implements a command-set-compatible, single-supply NOR Flash architecture with hot-electron injection programming and hot-hole assisted erase. Its VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability across mixed-voltage systems while maintaining full JEDEC compliance.

The internal state machine handles all erase and program operations autonomously; status is reported via DQ7 Data# Polling, DQ6/DQ2 toggle bits, or RY/BY# output. Sector-level granularity (64 KB uniform or 8 KB boot sectors) enables selective firmware updates without full chip erasure, and Erase/Program Suspend & Resume allows concurrent read access during background operations.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4,194,304 × 16-bit words); enables storage of full boot images and firmware for mid-complexity embedded systems.
Access Time	90 ns at VCC = 2.7–3.6 V, VIO = 2.7–3.6 V; ensures deterministic timing for real-time boot execution on ARM Cortex-M or RISC-V hosts.
Erase Endurance	100,000 cycles per sector; supports field firmware updates over 10+ years in industrial gateways with monthly OTA patches.
Data Retention	20 years at 125°C; validated for automotive under-hood and telecom base station applications requiring long-term reliability.
Supply Voltage	VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows direct interfacing to 1.8 V, 2.5 V, or 3.3 V I/O domains without level shifters.
Page Read Buffer	8-word (16-byte) buffer with 25 ns page access; reduces sequential read latency in instruction fetch scenarios.
Write Buffer	16-word (32-byte) buffer; cuts multi-word programming time by >40% versus single-word writes in configuration table updates.

Pinout & Package

Package: 48-pin TSOP (Standard Thin Small Outline Package), lead-free, RoHS-compliant, body size 12 mm × 20 mm.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 64 Mbit addressing; A-1 (DQ15/A-1) multiplexed for byte/word mode selection.
DQ0–DQ15	Data/Address Bus	16-bit bidirectional data bus; DQ15 doubles as A-1 for byte-mode configuration when BYTE# = low.
CE#, OE#, WE#	Chip/Output/Write Enable	Independent control lines enable standard microprocessor timing; CE# gating reduces standby current to 1 µA.
RY/BY#	Ready/Busy Output	Active-low open-drain signal indicating active erase/program; eliminates need for polling in time-critical boot loaders.
RESET#	Hardware Reset Input	Asynchronous reset terminates ongoing operations and restores device to known state; ties directly to system power-on reset circuitry.
WP#/ACC	Write Protect / Accelerated Program	Low-active write protect for first/last sector; high-voltage ACC mode reduces programming time during manufacturing or field updates.
BYTE#	Bus Width Select	Configures 16-bit (BYTE# = high) or 8-bit (BYTE# = low) data interface; enables compatibility with legacy 8-bit microcontrollers.

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 anti-cloning.
Password Sector Protection	128-bit password required to unlock protected sectors; prevents unauthorized firmware modification in certified medical or industrial equipment.
Program/Erase Suspend & Resume	Pause active programming/erasing to read other sectors; enables concurrent diagnostics and firmware update validation without halting system operation.
CFI Compliance	JEDEC-standard Common Flash Interface; allows automatic detection and parameter negotiation by host BIOS or bootloader without hard-coded timing tables.
VersatileI/O™ Control	VIO pin sets all input thresholds and output drive levels; simplifies integration into heterogeneous voltage systems (e.g., 1.8 V core + 3.3 V I/O).

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90TFI020	Same density and speed, but 56-pin TSOP package with different pinout (e.g., NC pins at positions 1–2, 55–56); no WP#/ACC dual function - separate WP# and ACC pins.	Requires PCB redesign due to pin count and signal mapping changes; lacks VIO flexibility (VIO fixed to VCC range).	Select only when board layout accommodates 56-pin footprint and system design does not require independent VIO control.
MX29GL640EHTI-90G	64 Mbit, 90 ns, but uses Macronix's MX29GL architecture; no Secured Silicon Sector or Password Protection; CFI compliant but with vendor-specific extensions.	Not suitable for security-critical boot applications; lacks factory-programmed ESN and persistent lock bits required for regulatory compliance.	Consider only for cost-sensitive, non-certified consumer electronics where firmware integrity is enforced externally.

Compared with S29GL064S90TFI020 and MX29GL640EHTI-90G, the S29GL064N90DAI033 uniquely combines VIO voltage independence, hardware-accelerated programming, and cryptographically anchored Secured Silicon Sector - making it the only option among the three qualified for ISO 13849 PLd and IEC 62304 Class C medical firmware storage.

FAQ

What is the purpose of the WP#/ACC pin on S29GL064N90DAI033?

The WP#/ACC pin serves two distinct functions: when driven low, it protects the first or last memory sector from accidental writes or erases; when driven high with elevated voltage (typically 5.5 V), it activates accelerated programming mode to reduce write times during manufacturing or field updates. This dual functionality eliminates the need for external voltage switching circuitry.

Does S29GL064N90DAI033 support 8-bit data bus operation?

Yes - when the BYTE# pin is asserted low, the device configures DQ0–DQ7 as an 8-bit data bus while DQ8–DQ15 become unused. Address bit A-1 is then sourced from DQ15, enabling compatibility with legacy 8-bit microcontrollers without external data bus multiplexing logic.

How is the Secured Silicon Sector protected and accessed?

The Secured Silicon Sector is a 128-word (256-byte) region pre-programmed with a unique 8-word electronic serial number (ESN) at the factory. Access requires a specific command sequence (0x00, 0x00, 0x90, 0x00, 0x00); once locked via the Persistent Protection Bit, no further writes or erases are possible - even with full VCC applied - ensuring permanent device identity.

Can S29GL064N90DAI033 be used in systems with mixed I/O voltages?

Yes - the VersatileI/O™ feature uses the VIO pin to set all input thresholds and output drive levels independently of VCC. With VIO supplied at 1.8 V, the device accepts 1.8 V logic inputs and drives 1.8 V outputs, while VCC remains at 3.0 V for core memory operation - enabling seamless integration into SoC platforms with heterogeneous voltage domains.
