Product details
Overview
S29AS008J70BFI033 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 with top/bottom configurable boot blocks. It delivers 70 ns access time, operates across -40°C to +85°C, supports CFI interface, and features hardware write protection via WP# and sector group locking for embedded firmware storage in microcontroller boot systems.
For engineers reviewing the S29AS008J70BFI033 datasheet, S29AS008J70BFI033 pinout, S29AS008J70BFI033 application, or S29AS008J70BFI033 equivalent, key selection criteria include 1.65–1.95 V single-supply operation, 1M/512K addressable configuration, Erase Suspend capability, Secured Silicon Sector with 128-word ESN, and FBGA/TSOP-48 package compatibility in industrial temperature environments.
Technical Context
The S29AS008J70BFI033 implements a JEDEC-compliant command-set architecture with internal state-machine control for Embedded Program and Embedded Erase algorithms. It uses Fowler-Nordheim tunneling for erase and hot electron injection for programming, enabling 1,000,000 program/erase cycles per sector and 20-year data retention.
Its dual-mode bus (x8/x16) is selected via BYTE# pin, with DQ15 functioning as A-1 in byte mode. Hardware features include RY/BY# for cycle completion detection, RESET# for immediate state-machine reset to read mode, and WP# to protect outermost boot sectors independently of software lock status.

Equivalent & Alternatives
The following parts are listed as comparable options for similar boot sector Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29AL008J70TFI020 | Same die, TSOP-48 package instead of FBGA; 70 ns access, identical command set and voltage range | Larger footprint and higher board-level thermal mass; less suitable for space-constrained portable designs | Select when legacy PCB layout requires through-hole or gull-wing mounting and thermal cycling is less aggressive |
| MX29LV008CTTI-70G | 8 Mbit, 3.0 V supply (2.7–3.6 V), 70 ns access; JEDEC-compatible but lacks Secured Silicon Sector and Erase Suspend | Requires level-shifting for 1.8 V systems; no hardware-based secure ID or background erase capability | Choose only if existing 3.3 V infrastructure prohibits voltage rail redesign and security features are non-critical |
Compared with S29AL008J70TFI020, the S29AS008J70BFI033 offers superior board-area efficiency and thermal performance in compact industrial enclosures; versus MX29LV008CTTI-70G, it enables secure, low-voltage, real-time firmware updates without external support circuitry.

FAQ
Is S29AS008J70BFI033 pin-compatible with S29AS008J70TFI020?
Yes - both share identical 48-pin functional mapping and command set, differing only in package type (FBGA vs. TSOP). The ball-to-lead assignments match one-to-one for all signal pins including CE#, OE#, WE#, RY/BY#, RESET#, and WP#. No PCB redesign is needed when migrating between these variants.
Does the Secured Silicon Sector support customer programming in-system?
Yes - the 128-word Secured Silicon Sector can be programmed and permanently locked either at the factory or in the field using standard command sequences. Once locked, the sector becomes read-only and immune to further erase or program commands, even under elevated voltage or reset conditions.
What is the minimum pulse width required for RESET# to guarantee recovery to read mode?
The RESET# pin requires a minimum active-low pulse width of 100 ns to reliably terminate ongoing program/erase operations and force the internal state machine into array-read mode. This specification is validated across the full -40°C to +85°C temperature range and 1.65–1.95 V supply window.
Can Erase Suspend be used during Chip Erase operations?
No - Erase Suspend is supported only during Sector Erase operations. Chip Erase is atomic and cannot be interrupted or suspended. Attempting Erase Suspend during Chip Erase has no effect and does not alter the erase progress or status bits; the operation continues to completion without pause.
