Product details
Overview
S29AL008J70TFA020 from Infineon Technologies (formerly Cypress) is an 8 Mbit, 3.0 V-only boot sector Flash memory organized as 1 M × 8-bit or 512 K × 16-bit, featuring 55 ns access time, AEC-Q100 Grade 1 (–40°C to +125°C), and flexible sector architecture with one 16 KB, two 8 KB, one 32 KB, and fifteen 64 KB sectors. It supports in-system programming via standard 3.0 V VCC, includes Secured Silicon Sector with factory-programmable 128-word ESN, and is used in automotive engine control units for boot firmware storage.
For engineers reviewing the S29AL008J70TFA020 datasheet, S29AL008J70TFA020 pinout, S29AL008J70TFA020 application, or S29AL008J70TFA020 equivalent, key selection criteria include boot-block configuration (top/bottom), sector protection granularity, CFI compliance for host auto-configuration, RY/BY# hardware status signaling, and 2.7–3.6 V single-supply operation across extended temperature ranges.
Technical Context
The S29AL008J70TFA020 implements a command-register-driven state machine for Embedded Erase and Embedded Program algorithms, enabling automatic pulse-width control, margin verification, and pre-programming prior to erase. Its architecture integrates Fowler-Nordheim tunneling for erase and hot-electron injection for program operations.
It supports dual data width modes (x8/x16) via BYTE# pin, JEDEC-compliant software commands, and hardware features including WP#-controlled boot-sector write protection, RESET#-initiated state reset, and RY/BY# output for cycle completion detection - all operating within a single 3.0 V supply without external high-voltage generation.

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 × 12.0 mm); higher thermal resistance than BGA | Preferred for prototyping or legacy PCBs with through-hole or gull-wing footprint constraints | Select when board layout lacks BGA reflow capability or requires manual inspection |
| MX29LV008CTTI-70G | 8 Mbit, 3 V, 70 ns access; no Secured Silicon Sector; CFI v1.1 (vs. v1.3) | Lacks factory-programmable ESN and temporary unprotect; limited to non-secure boot applications | Choose only for cost-sensitive, non-automotive designs where secure ID and sector flexibility are unnecessary |
Compared with S29AL008J70TFA020, the TSOP variant trades thermal performance for assembly simplicity, while the MX29LV008CTTI-70G omits security and suspend features - making the BGA version optimal for space-constrained, safety-critical automotive deployments requiring guaranteed boot integrity.

FAQ
Is S29AL008J70TFA020 pin-compatible with earlier S29AL008D devices?
Yes - it is fully compatible with the 200 nm S29AL008D in both pinout and software command set, as confirmed by Infineon's migration documentation. The 110 nm process improves power efficiency and thermal performance while maintaining identical mechanical and electrical interface behavior across TSOP and BGA packages.
What is the function of the BYTE# pin, and how does it affect data bus width?
BYTE# selects between x8 and x16 data organization: when pulled low, DQ0–DQ7 operate as an 8-bit bus with A-1 unused; when high, DQ0–DQ15 form a 16-bit bus with DQ15/A-1 serving as data bit 15. This pin must be statically configured at power-up and cannot be changed dynamically during operation.
Does the Secured Silicon Sector support field programming of the Electronic Serial Number?
Yes - the 128-word Secured Silicon Sector can be programmed and locked either at the factory or by the end customer using standard command sequences. Once locked, the 8-word ESN region becomes permanently read-only, providing cryptographically verifiable device identity for secure boot and anti-counterfeiting applications.
How does Erase Suspend improve real-time system responsiveness?
Erase Suspend allows an ongoing sector erase to be paused within 2 µs, enabling immediate read or program access to any other non-erasing sector. This permits concurrent firmware validation or parameter updates during background erase - essential for deterministic response in automotive and industrial control loops without sacrificing storage density.
