Infineon Technologies S29GL064S70TFA040

Overview

S29GL064S70TFA040 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory IC using 65-nm MIRRORBIT™ technology, operating from a single 3.0 V supply with 70 ns access time, 128-word write buffer, and integrated hardware ECC for single-bit error correction. It features uniform 64-KB sectors, industrial temperature range (–40°C to +85°C), and 48-lead TSOP package - deployed in boot firmware storage for industrial controllers.

For engineers reviewing the S29GL064S70TFA040 datasheet, S29GL064S70TFA040 pinout, S29GL064S70TFA040 application, or S29GL064S70TFA040 equivalent, key selection criteria include JEDEC-compliant command set, sector-level erase flexibility, Secure Silicon Region programmability, VIO-controlled I/O voltage range (1.65 V to VCC), and AEC-Q100 Grade 3 qualification status.

Technical Context

This device implements a parallel asynchronous interface with separate CE#, WE#, and OE# controls, supporting both 16-bit word and 8-bit byte configurations via BYTE# input. Its architecture enables simultaneous read/program or read/erase operations through Program Suspend and Erase Suspend features.

Internal hardware ECC operates transparently during read cycles, correcting single-bit errors without host intervention. The Secure Silicon Region provides a factory- or customer-lockable 128-word (256-byte) area with permanent protection enforced by command-sequence-based locking and PPB bit control.

FAQ

What is the function of the WP#/ACC pin on S29GL064S70TFA040?

The WP#/ACC pin serves dual functions: when held low, it hardware-protects the first or last memory sector against accidental program/erase; when pulsed with elevated voltage (V_ACC), it enables accelerated programming for faster production-line flashing. This pin remains active even during Secure Silicon Region locking and does not affect internal ECC operation.

Does S29GL064S70TFA040 support byte-wide data access?

Yes - the device supports 8-bit data access when the BYTE# input is asserted low, configuring DQ0–DQ7 as the active data bus while disabling DQ8–DQ15. This mode maintains full command-set compatibility and preserves sector protection settings, enabling integration with legacy 8-bit microcontrollers without external data-width translation.

How does the Secure Silicon Region differ from standard sector protection?

The Secure Silicon Region is a dedicated 128-word (256-byte) area that can be permanently locked via command sequence and PPB bit, preventing any further writes or erases - unlike standard sector protection, which remains reversible via unlock commands. Once locked, this region retains its contents for 20 years and is inaccessible to standard erase commands, even during chip erase.

Is the 70 ns access time guaranteed across the full industrial temperature range?

Yes - the 70 ns access time is specified and tested over the full –40°C to +85°C industrial temperature range at V_CC = 3.0 V ±0.3 V and specified capacitive load. This timing includes address setup and hold margins and is validated per JEDEC JESD22-A108 reliability standards, ensuring deterministic boot performance in uncontrolled thermal environments.
