Product details
Overview
S29AL008J70TFN023 from Infineon Technologies (formerly Cypress) is an 8 Mbit (1M × 8-bit / 512K × 16-bit), 3.0 V-only boot sector Flash memory with 55 ns access time, automotive-grade AEC-Q100 Grade 1 support (–40°C to +125°C), and flexible sector architecture including one 16 KB, two 8 KB, one 32 KB, and fifteen 64 KB sectors. It operates across 2.7–3.6 V, supports in-system programming without high-voltage VPP, and integrates hardware write protection via WP# and RESET# pins for embedded boot code storage.
For engineers reviewing the S29AL008J70TFN023 datasheet, S29AL008J70TFN023 pinout, S29AL008J70TFN023 application, or S29AL008J70TFN023 equivalent, key selection considerations include boot sector configuration (top/bottom), CFI compliance for host auto-detection, Erase Suspend/Resume capability for real-time firmware updates, and 1M-cycle endurance per sector with 20-year data retention.
Technical Context
The S29AL008J70TFN023 implements a command-register-driven state machine for Embedded Erase and Embedded Program algorithms, eliminating external timing control. It uses Fowler-Nordheim tunneling for erase and hot electron injection for program operations, with internal voltage regulation enabling single 3.0 V supply operation.
Its dual-mode interface supports byte (DQ7–DQ0) and word (DQ15–DQ0) configurations via BYTE# pin, while hardware features-including RY/BY# status output, DQ7 Data# Polling, and DQ6/DQ2 toggle bits-enable precise operation monitoring without software polling overhead.

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 (18.4 mm × 12.0 mm), 70 ns access time, industrial temp (–40°C to +85°C) | Lacks AEC-Q100 Grade 1 qualification; suitable for non-automotive industrial control | Select when board layout requires TSOP footprint and automotive temperature range is not required |
| MX29LV008CTTI-70G | 8 Mbit, 3.0 V, 70 ns, PLCC-32 package; no CFI support; no Secured Silicon Sector | No Erase Suspend or hardware sector protection; limited security features | Choose only for legacy designs where CFI and secure ID are unnecessary and PLCC mounting is mandated |
Compared with S29AL008J70TFN023, the TSOP variant trades automotive qualification and speed for package compatibility, while the MX29LV008CTTI sacrifices CFI, secure ID, and suspend functionality for cost-sensitive, non-safety-critical applications.

FAQ
Is S29AL008J70TFN023 pin-compatible with earlier S29AL008D devices?
Yes - the S29AL008J70TFN023 maintains identical pinout and software command compatibility with the S29AL008D, as confirmed by Infineon's documentation stating full 200 nm S29AL008D process compatibility and JEDEC pinout adherence. This enables drop-in replacement in existing designs without PCB revision.
What is the function of the BYTE# pin, and how does it affect data bus width?
The BYTE# pin selects between 8-bit (BYTE# = LOW) and 16-bit (BYTE# = HIGH) data interface modes. In byte mode, DQ7–DQ0 carry data and A-1 is input on DQ15; in word mode, DQ15–DQ0 carry full 16-bit data. This dual-mode flexibility supports both legacy 8-bit microcontrollers and modern 16-bit bus architectures.
Does S29AL008J70TFN023 support simultaneous read and erase operations?
No - it supports Erase Suspend/Erase Resume, allowing an ongoing sector erase to be paused so another sector can be read or programmed, but true concurrent read-while-erase is not implemented. The suspended erase resumes automatically after the foreground operation completes, enabling deterministic firmware update sequences.
How is hardware write protection implemented on the boot sectors?
Hardware write protection is enforced via the WP# pin: when driven LOW, it locks either the top 16 KB (for top-boot configuration) or bottom 16 KB (for bottom-boot) against program and erase commands. This protection is active regardless of software commands and persists through power cycles, ensuring boot code immunity to accidental corruption.
