Product details
Overview
S29AL008J70BAN020 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 features hardware write protection via WP#, Ready/Busy# signaling, and CFI compliance for host software reconfiguration in embedded boot applications.
For engineers reviewing the S29AL008J70BAN020 datasheet, S29AL008J70BAN020 pinout, S29AL008J70BAN020 application, or S29AL008J70BAN020 equivalent, key selection criteria include boot-sector configuration (top/bottom), sector group protection granularity, erase suspend/resume capability, and compatibility with JEDEC single-power-supply Flash command sets in safety-critical automotive and industrial firmware storage designs.
Technical Context
The S29AL008J70BAN020 implements a command-register-driven state machine that executes embedded program and erase algorithms-automatically timing pulses and verifying cell margin without external voltage programming. Its dual-mode interface supports byte (DQ7–DQ0) and word (DQ15–DQ0) data widths via BYTE# control, with address latch A0–A18 enabling full 8 Mbit addressing.
Hardware protection includes VCC detector–based write inhibition during power transitions, dedicated WP# pin for boot-sector lock, and RESET#-driven state-machine reset to array-read mode. Erase suspend/resume enables concurrent read/program operations in non-erasing sectors, supporting true background erase in real-time firmware update scenarios.

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 |
|---|---|---|---|
| S29AL008J70TFN020 | Same die, TSOP-48 package (18.4 mm × 12.0 mm) instead of BGA; identical timing and command set | Preferred for through-hole prototyping or legacy PCB layouts with TSOP footprints | Select when mechanical compatibility with existing TSOP sockets or wave-solder assembly is required |
| MX29LV008CTTI-70G | 8 Mbit 3V Flash with 70 ns access, but lacks CFI support and secured silicon sector; different sector map (eight 8 KB + one 64 KB boot) | Acceptable for cost-sensitive industrial controls where serial number binding and auto-configuration are not needed | Choose only if CFI, erase suspend, and secure ID features are unnecessary and 15 ns slower access is acceptable |
Compared with S29AL008J70TFN020, the BGA variant offers superior thermal performance and board space efficiency for automotive modules; versus MX29LV008CTTI-70G, it delivers critical safety-enabling features-CFI, secure silicon, and erase suspend-that justify its use in certified systems despite higher unit cost.

FAQ
What boot sector configuration does S29AL008J70BAN020 support?
The S29AL008J70BAN020 supports both top-boot and bottom-boot configurations, selectable via hardware strapping or command sequence. In top-boot mode, the highest 16 KB sector (addresses 0xFFC000–0xFFFFFF) is protected; in bottom-boot, the lowest 16 KB sector (0x000000–0x003FFF) is protected. WP# pin state determines default behavior at power-up.
Does S29AL008J70BAN020 require external high-voltage programming?
No. The S29AL008J70BAN020 operates exclusively from a single 3.0 V supply (2.7–3.6 V range) for all read, program, and erase functions. Internal charge pumps generate required high voltages for Fowler-Nordheim tunneling and hot-electron injection, eliminating need for 5 V or 12 V VPP rails or external programming equipment.
How is the Secured Silicon Sector programmed and locked?
The Secured Silicon Sector (128 words / 256 bytes) is programmed using the standard Word Program command sequence after entering Secured Silicon Sector mode. Locking is performed via the Sector Protect command; once locked, the sector becomes permanently read-only. Factory locking is available during wafer sort; customer locking is supported in-system using the same command set.
Can S29AL008J70BAN020 be used in place of older S29AL008D devices?
Yes-S29AL008J70BAN020 is fully pin- and command-compatible with the 200 nm S29AL008D, while offering improved performance (55 ns vs. 70 ns), lower power consumption, and enhanced features including CFI, erase suspend, and secured silicon. Migration requires no PCB or firmware changes beyond validation of timing margins in high-speed interfaces.
