Product details

Overview

S29GL064S80BHB043 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, 128-word write buffer, internal hardware ECC for single-bit correction, and secure silicon region with factory-programmed 8-word electronic serial number. It is used in industrial embedded boot code storage where deterministic timing, sector-level erase control, and persistent firmware protection are required.

For engineers reviewing the S29GL064S80BHB043 datasheet, S29GL064S80BHB043 pinout, S29GL064S80BHB043 application, or S29GL064S80BHB043 equivalent, key selection criteria include uniform 64-KB sector architecture, VIO-referenced I/O (1.65–VCC), AEC-Q100 Grade 2 qualification (–40°C to +105°C), and JEDEC-compliant command set with Unlock Bypass programming mode.

Technical Context

This device implements a parallel interface with separate CE#, WE#, and OE# controls, supporting both 16-bit-only and byte-configurable (via BYTE#) data bus operation. Its MIRRORBIT™ 65-nm process enables hot-hole erase and hot-electron programming with 100,000 erase cycles per sector and 20-year data retention.

The architecture includes dedicated hardware features: RESET# for operation termination and boot recovery, RY/BY# for cycle status indication, WP#/ACC for first/last sector hardware write protection, and automatic low-VCC write inhibition. Secure Silicon Region is a permanently locked 256-byte area accessible only via command sequence.

Equivalent & Alternatives

The following parts are listed as comparable options for similar parallel NOR flash applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90BHI043	Same die, 90 ns access time, 48-ball BGA (VBK048), industrial temperature (–40°C to +85°C)	Lacks AEC-Q100 qualification and +105°C support	Select when cost sensitivity outweighs extended temperature or automotive compliance needs
MX29GL640EHT2I-90G	64 Mb parallel NOR, 90 ns, Macronix, 48-TSOP, no Secure Silicon Region or hardware ECC	No factory-locked serial number or internal error correction	Choose for legacy TSOP footprint compatibility where security and ECC are handled externally

Compared with S29GL064S80BHB043, the S29GL064S90BHI043 trades speed and temperature margin for lower cost, while MX29GL640EHT2I-90G sacrifices security and ECC for broader package availability and simpler integration in non-safety-critical systems.

FAQ

What is the function of the BYTE# pin on S29GL064S80BHB043?

The BYTE# pin configures the data bus width: when high, DQ0–DQ15 operate as a full 16-bit word interface; when low, only DQ0–DQ7 are active as an 8-bit byte interface. This dual-mode capability allows backward compatibility with legacy 8-bit microcontrollers while supporting modern 16-bit architectures without redesigning the PCB layout.

Does S29GL064S80BHB043 support execute-in-place (XIP) operation?

Yes - its parallel interface, 70 ns access time, and deterministic read timing enable direct execution of code from flash without copying to RAM. The device supports standard microprocessor bus cycles with CE#, OE#, and WE# handshaking, making it compatible with XIP-capable ARM Cortex-M and Power Architecture microcontrollers in boot ROM configurations.

How is the Secure Silicon Region protected from unauthorized access?

Access to the 256-byte Secure Silicon Region requires execution of a specific 6-cycle command sequence followed by a 3-cycle unlock sequence. Once programmed and locked (via PPB lock bit), the region becomes permanently read-only and immune to erase or program commands - even under accelerated programming voltage applied to WP#/ACC. Factory programming ensures uniqueness and tamper resistance.

Can S29GL064S80BHB043 be used in systems with mixed 1.8 V and 3.0 V I/O domains?

Yes - the VIO pin sets input threshold and output drive levels independently of VCC. With VIO supplied at 1.8 V, all address, control, and data signals operate at 1.8 V logic levels while VCC remains at 3.0 V for core functionality. This allows seamless interfacing with 1.8 V FPGAs or microcontrollers without level shifters, provided VIO stays within 1.65 V to VCC range.
