Infineon Technologies S29GL064S80DHV030

Overview

S29GL064S80DHV030 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, and integrated hardware ECC for single-bit error correction. It features uniform 64-KB sectors, secure silicon region with factory-programmed 16-byte serial number, and operates across industrial temperature range (–40°C to +85°C) in 48-lead TSOP package.

For engineers reviewing the S29GL064S80DHV030 datasheet, S29GL064S80DHV030 pinout, S29GL064S80DHV030 application, or S29GL064S80DHV030 equivalent, this device supports boot code storage, firmware update in embedded controllers, and secure configuration data retention in automotive ECUs and industrial HMIs where JEDEC-compliant parallel interface and sector-level protection are required.

Technical Context

The S29GL064S80DHV030 implements MIRRORBIT™ charge-trapping flash technology on a 65-nm process, enabling hot-electron programming and hot-hole assisted erase. It uses command-set-compatible JEDEC-standard parallel interface with separate CE#, WE#, and OE# controls, supporting both word (16-bit) and byte (8-bit via BYTE#) configurations.

Hardware-level data integrity is enforced through automatic internal ECC, low-VCC write inhibition, and RESET#-driven operation reset. Sector protection includes persistent lock bits and password-protected regions, while Program/Erase Suspend/Resume enables concurrent read/program operations across non-overlapping sectors.

FAQ

What is the function of the WP#/ACC pin on S29GL064S80DHV030?

The WP#/ACC pin serves dual roles: when held low, it hardware-protects the first or last sector regardless of software protection settings; when driven high with an elevated voltage (VHH ≈ 11.5 V), it enables accelerated programming for faster production-line firmware loading. This pin is electrically isolated from VCC and requires external voltage control during ACC mode.

Does S29GL064S80DHV030 support byte-wide data access?

Yes, it supports 8-bit data access via the BYTE# input pin. When BYTE# is asserted high, only DQ0–DQ7 are active and DQ8–DQ15 are tri-stated, enabling connection to 8-bit microcontrollers without data bus translation. The device retains full 16-bit addressing and sector architecture regardless of bus width mode.

How does the Secure Silicon Region differ from standard flash sectors?

The Secure Silicon Region is a dedicated 128-word (256-byte) sector that can be permanently locked at factory or by customer using a command sequence. Once locked, no further writes or erases are possible-even with valid passwords or unlock commands-and it contains a unique 16-byte electronic serial number used for device authentication and secure key binding.

Can S29GL064S80DHV030 operate with VIO = 1.8 V while VCC = 3.0 V?

Yes, VIO may be independently set between 1.65 V and VCC (3.0 V), including 1.8 V, to interface with low-voltage I/O domains. All address, control, and data signals are referenced to VIO, while core logic and flash array remain powered by VCC. This allows seamless integration with 1.8 V FPGAs or microcontrollers without level shifters.
