Product details
Overview
S29GL064S70BHI043 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, and 65-nm MIRRORBIT™ process technology. It features uniform 64-KB sectors, internal hardware ECC for single-bit error correction, and secure silicon region with factory-programmed 16-byte electronic serial number. Used in industrial embedded boot code storage and firmware update storage.
For engineers reviewing the S29GL064S70BHI043 datasheet, S29GL064S70BHI043 pinout, S29GL064S70BHI043 application, or S29GL064S70BHI043 equivalent, key selection factors include parallel 16-bit bus interface, industrial temperature range (–40°C to +85°C), TSOP-48 package, sector erase architecture, and JEDEC-compliant command set for host system integration.
Technical Context
This device implements a parallel asynchronous interface with separate CE#, OE#, and WE# controls, supporting both word (16-bit) and byte (8-bit via BYTE#) configurations. Its MIRRORBIT™ architecture enables simultaneous hot-hole erase and hot-electron programming across full sectors.
Hardware-level data integrity is enforced through automatic ECC on read, DQ7 polling and DQ6 toggle bit status monitoring, and RESET#-driven operation abort. Sector protection includes persistent lock bits and password-protected regions, with WP#/ACC input enabling hardware write protection of first/last sector independent of software settings.
Key Specifications

Pinout & Package
48-lead TSOP (Thin Small Outline Package), Type I, 12 mm × 20 mm body, 0.5 mm lead pitch, JEDEC MO-141AC compliant. Pin 1 marked by notch or dot; leads are gull-wing profile, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A22 | Address Inputs | 23-bit address bus supporting full 4-Mword addressing; A0 selects LSB in word mode |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; operates as 8-bit when BYTE# = low |
| CE# | Chip Enable | Active-low enable controlling device selection; must be asserted before OE# or WE# |

| RESET# | Hardware Reset | Active-low asynchronous reset terminating all operations and returning to read mode |
| RY/BY# | Ready/Busy Output | Open-drain status signal indicating active program/erase cycle (low) or completion (high) |
| WP#/ACC | Write Protect / Accelerated Program | Low = hardware sector protection; high voltage = accelerated programming mode |
| BYTE# | Bus Width Select | Low = 8-bit data mode (DQ0–DQ7 only); high = 16-bit word mode |
| VCC, VSS | Power / Ground | 3.0 V core and I/O supply; VIO not present - all I/O referenced to VCC |
Key Features
| Feature | Design Value |
|---|---|

| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles - cuts total firmware write time by ~35% in burst scenarios |
| Advanced Sector Protection | Persistent lock bits + password-protected sectors - prevents unauthorized firmware modification while allowing selective field updates |
| Automatic Hardware ECC | Single-bit correction on every read without CPU intervention - ensures data integrity in electrically noisy industrial environments |
Applications
| Industrial PLC Firmware Storage | Automotive ECU Boot Memory |
|---|---|
Use Scenario: Storing ladder logic firmware and configuration data in programmable logic controllers operating in factory-floor environments with wide temperature swings and EMI. IC Role / Device Role / Timing Role: Primary nonvolatile boot memory mapped to microcontroller's address space; accessed asynchronously during power-on initialization. Use Value: 70 ns access time enables zero-wait-state boot execution; 20-year data retention ensures firmware persistence over equipment lifetime without refresh. | Use Scenario: Holding bootloader and safety-critical calibration data in engine control units certified to AEC-Q100 Grade 3. IC Role / Device Role / Timing Role: Secure boot ROM providing authenticated startup sequence and protected calibration tables accessible only after hardware reset. Use Value: Secure Silicon Region stores cryptographic keys and serial ID; hardware WP#/ACC protects first sector containing bootloader against corruption. |
| Medical Device Configuration Storage | Networking Equipment Image Backup |
Use Scenario: Retaining device-specific calibration parameters and regulatory compliance settings in Class II medical imaging systems requiring traceable configuration history. IC Role / Device Role / Timing Role: Dedicated parameter storage partitioned from main application code; updated infrequently but with absolute write-protection assurance. Use Value: Password sector protection prevents accidental or malicious overwrite; 100,000-cycle endurance supports decades of recalibration events. | Use Scenario: Maintaining fallback firmware images in enterprise switches and routers where primary flash may become corrupted during remote upgrades. IC Role / Device Role / Timing Role: Secondary parallel NOR image store accessed only during recovery mode; isolated from main boot path via separate CE# routing. Use Value: Uniform 64-KB sector architecture allows atomic image replacement; ECC ensures fallback image integrity even after years of storage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90BHI043 | 90 ns access time; identical density, package, and feature set | Lower performance grade; suitable where timing margin >20 ns exists | Select when system clock frequency ≤11 MHz and cost sensitivity outweighs speed requirement |
| MX29GL640EHTI-90G | Macronix part; 90 ns access, same 48-TSOP package, JEDEC-compatible but no Secure Silicon Region | Lacks factory-programmed serial number and persistent lock register; requires external security layer | Choose for cost-driven designs where cryptographic identity and hardware-level sector locking are not required |
Compared with S29GL064S90BHI043, the -70 variant delivers 20 ns faster access for tighter timing budgets; versus MX29GL640EHTI-90G, it adds secure silicon and enhanced sector protection-critical for regulated firmware storage where tamper resistance is mandated.

FAQ
Is S29GL064S70BHI043 pin-compatible with earlier S29GL064N or S29GL064P devices?
No. While functionally similar, S29GL064S uses a revised pinout: BYTE# replaces A-1, and RY/BY# replaces ACC. The TSOP-48 footprint is identical, but signal mapping differs - PCB layout revision is required for migration from N/P to S series.
Does this device support 8-bit data bus operation?
Yes. When BYTE# is driven low, the device operates in 8-bit mode using DQ0–DQ7 only. Address lines remain fully decoded; A0 selects the lower byte within each 16-bit word. This mode maintains full sector erase and program functionality.
What is the purpose of the WP#/ACC pin in normal operation?
In normal operation, WP#/ACC serves dual roles: logic-low asserts hardware write protection on the first or last sector (configurable), independent of software locks; logic-high with 5.5 V applied enables accelerated programming mode for reduced write times during manufacturing.
Can the Secure Silicon Region be erased or rewritten after factory programming?
No. Once locked via the PPB (Persistent Protection Bit), the 128-word Secure Silicon Region becomes permanently read-only. Factory programming of the 16-byte serial number occurs pre-lock; customer programming is allowed only before final lock, and no unlock mechanism exists post-lock.
