Product details

Overview

S29AS008J70BFI032 from Infineon Technologies (formerly Cypress) is an 8 Mbit, 1.8 V-only boot sector Flash memory organized as 1M × 8-bit or 512K × 16-bit, featuring top/bottom boot architecture, 70 ns access time, and industrial temperature range (–40°C to +85°C). It supports in-system programming/erasure via standard 1.8 V V_CC, includes Secured Silicon Sector with 256-byte factory-programmable serial ID, and is used in embedded boot code storage for microcontrollers in industrial control and networking edge devices.

For engineers reviewing the S29AS008J70BFI032 datasheet, S29AS008J70BFI032 pinout, S29AS008J70BFI032 application, or S29AS008J70BFI032 equivalent, key selection criteria include boot sector protection granularity, CFI compliance for host auto-configuration, erase suspend/resume capability for real-time firmware updates, and dual-package availability (48-ball FBGA/VBK048 and 48-pin TSOP).

Technical Context

The S29AS008J70BFI032 implements a JEDEC-compliant single-power-supply Flash command set with embedded algorithms for automatic program pulse timing, margin verification, and pre-erase programming. Its internal state machine interprets command sequences written to the command register using standard microprocessor write timings, eliminating external high-voltage generation.

It features hardware-based sector group protection with temporary unprotect capability, RY/BY# status signaling, and DQ6/DQ7 polling for operation completion detection. The device integrates a low-V_CC detector for power-transition write inhibition and supports both byte (x8) and word (x16) data bus configurations via the BYTE# pin.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL032N90TFI020	64 Mbit density, 90 ns access, 3.0 V supply - higher capacity but incompatible voltage domain and slower timing.	Requires level-shifting and redesign of power delivery; suited for legacy 3 V systems, not drop-in replacement.	Select only if migrating to larger firmware images and upgrading entire power architecture.
MX29LV008CTTI-70G	8 Mbit, 70 ns, 3.0 V supply - identical density/timing but 3 V operation and no CFI support.	Lacks CFI auto-configuration and Secured Silicon Sector; requires custom driver development and manual sector mapping.	Choose only for cost-sensitive 3 V designs where firmware size is static and security features are unnecessary.

Compared with S29GL032N90TFI020 and MX29LV008CTTI-70G, the S29AS008J70BFI032 uniquely delivers 1.8 V operation with CFI, erase suspend, and factory-secured identity - making it the only option for modern low-power, upgradable, and traceable embedded boot systems.

FAQ

Is S29AS008J70BFI032 pin-compatible with other S29AS008J speed grades?

Yes - all S29AS008J variants (e.g., S29AS008J70BFI020, S29AS008J70BFI032) share identical 48-ball FBGA (VBK048) pinout and electrical interface. Speed grade differences (70 ns vs. 90 ns) affect only AC timing parameters; no PCB or firmware changes are needed when substituting within the same package.

Does the Secured Silicon Sector require special programming equipment?

No - the Secured Silicon Sector is programmed using the same command sequences as main array sectors (e.g., Word Program, Sector Erase), accessible via standard microcontroller GPIO or JTAG-based flash programmers. Factory locking is performed during wafer test; customer locking uses the Sector Group Protect command with valid unlock sequence.

Can S29AS008J70BFI032 operate in byte mode on a 16-bit bus?

Yes - when BYTE# is driven LOW, the device operates in 8-bit mode: DQ7–DQ0 carry data, DQ15 functions as A-1 (LSB address), and DQ14–DQ8 are tri-stated. This allows use on 16-bit buses without hardware modification, provided the host asserts BYTE# and ignores upper data bits during transfers.

What happens during power loss while an erase operation is in progress?

The device's internal low-V_CC detector halts all write/erase activity when V_CC drops below 1.4 V, preserving sector integrity. Upon power restoration, the device resumes normal read mode; incomplete erase operations do not corrupt adjacent sectors, and status bits (DQ7/DQ6) indicate aborted state - requiring explicit re-issuance of the erase command.
