Product details

Overview

S29GL064N11DFIV20 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 implements uniform sector architecture with 128 × 64 KB sectors and supports both 8-bit and 16-bit data bus operation via BYTE# control - deployed in industrial control firmware storage and boot code retention systems.

For engineers reviewing the S29GL064N11DFIV20 datasheet, S29GL064N11DFIV20 pinout, S29GL064N11DFIV20 application, or S29GL064N11DFIV20 equivalent, key selection criteria include JEDEC-compliant command set compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, hardware write protection via WP#/ACC, and CFI compliance for host auto-configuration.

Technical Context

This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole assisted sector erase and hot-electron injection programming. Its VersatileI/O™ architecture decouples I/O voltage (VIO = 1.65–3.6 V) from core supply (VCC = 2.7–3.6 V), allowing interoperability with mixed-voltage host systems.

The command-set architecture supports Program Suspend/Resume and Erase Suspend/Resume - enabling concurrent read operations during active programming or erasure of other sectors. Status reporting is implemented via DQ7 Data# Polling, DQ6/DQ2 toggle bits, and RY/BY# output.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4,194,304 × 16-bit words); enables full boot firmware + configuration storage in single device
Access Time	90 ns at VCC = 2.7–3.6 V; meets real-time boot latency requirements for embedded microcontrollers
Erase Endurance	100,000 cycles per sector; supports field firmware updates over product lifetime
Data Retention	20 years at 125°C; validated for automotive under-hood and industrial high-temp environments
Supply Voltage	VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows direct interface with 1.8 V or 3.3 V logic without level shifters
Page Read Buffer	8-word (16-byte) buffer; reduces sequential read latency in instruction fetch scenarios
Write Buffer	16-word (32-byte) buffer; cuts multi-word programming time by >40% vs. byte-by-byte writes

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-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 I/O Bus	16-bit bidirectional data path; operates as 8-bit bus when BYTE# = low (x8 mode)
CE#	Chip Enable	Active-low chip select; device enters standby when CE# high, independent of OE#/WE# state
OE#	Output Enable	Active-low read strobe; controls output drivers only; does not affect internal state machine
WE#	Write Enable	Active-low write strobe; latches addresses/data for command execution and programming
WP#/ACC	Write Protect / Accelerated Program	Low = hardware sector lock (first/last sector); high + VHH = accelerated programming (factory throughput)
RY/BY#	Ready/Busy Output	Open-drain active-low status signal; asserts low during program/erase; used for polling-free timing
RESET#	Hardware Reset	Active-low asynchronous reset; terminates ongoing operation and returns device to read mode
BYTE#	Bus Width Select	Low = x8 mode (DQ0–DQ7 only active); high = x16 mode (full DQ0–DQ15 used)

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory-locked region with 8-word ESN; prevents cloning and enables secure device identity binding
Advanced Sector Protection	Persistent Sector Protection (PPB) + Password Sector Protection (PSP); eliminates need for external security ICs in firmware update paths
CFI Compliance	JEDEC JESD68-compliant interface; enables automatic detection and parameter loading by bootloader without hard-coded offsets
Erase Suspend/Resume	Pause erase in one sector to read/program another; critical for real-time systems requiring background firmware validation
Unlock Bypass Mode	Two-cycle programming sequence instead of four; reduces firmware update time by ~33% in mass production

Equivalent & Alternatives

The following parts are listed as comparable options for similar Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S11TFIV20	Same density and timing, but 56-pin TSOP package; no BYTE# pin - fixed x16-only interface	Used where board layout requires larger pad pitch and x16-only data path simplifies routing	Select when footprint compatibility with legacy 56-pin layouts is required and x8 mode is unnecessary
MX29GL640EHTI-90G	64 Mbit, 90 ns, but uses 130 nm process; lacks Secured Silicon Sector and CFI support	Lower-cost alternative where secure identity and host auto-configuration are not required	Choose for cost-sensitive consumer applications lacking firmware integrity or secure boot needs

Compared with S29GL064S11TFIV20, the S29GL064N11DFIV20 offers flexible x8/x16 bus width and smaller 48-pin footprint; versus MX29GL640EHTI-90G, it delivers certified 20-year retention, factory-secured identity, and JEDEC-standard CFI - essential for industrial and automotive deployments.

FAQ

Does S29GL064N11DFIV20 support both 8-bit and 16-bit data bus modes?

Yes. The BYTE# input selects bus width: high enables full 16-bit operation (DQ0–DQ15), low restricts to 8-bit mode (DQ0–DQ7). This is confirmed in the "Word/Byte Configuration" section (page 16) and pin description table (page 9) of datasheet 001-98525 Rev. *B. No external logic is needed to switch modes.

What is the function of the WP#/ACC pin beyond write protection?

WP#/ACC serves dual roles: asserted low provides hardware-level write protection for first/last sector regardless of software protection settings; asserted high with elevated voltage (VHH ≈ 11.5 V) enables accelerated programming for faster factory throughput. This dual functionality is documented in Section 8.16 and Figure 1 of the datasheet.

Is the Secured Silicon Sector programmable by the end customer?

Yes - the 128-word Secured Silicon Sector can be programmed and locked either at the factory or by the customer using the Enter/Exit Secured Silicon Sector command sequence (Section 10.4). Once locked, it becomes permanently read-only and immune to erase commands, preserving ESN or cryptographic keys.

How does the device indicate completion of a program or erase operation?

Three independent status mechanisms are provided: DQ7 Data# Polling (DQ7 toggles then locks to complement of written data), DQ6/DQ2 toggle bits (DQ6 toggles during operation), and RY/BY# output (active-low open-drain signal). All are electrically verified in AC Characteristics Table 15-1 and described in Sections 10.11–10.13.
