Infineon Technologies S29AL016J70BFI023

Overview

S29AL016J70BFI023 from Infineon Technologies (formerly Cypress) is a 16 Mbit (2M × 8-bit / 1M × 16-bit), 3.0 V-only boot sector Flash memory with 55 ns access time, AEC-Q100 Grade 1 (–40°C to +125°C) qualification, and flexible sector architecture including one 16 KB, two 8 KB, one 32 KB, and thirty-one 64 KB sectors - deployed in automotive engine control units for firmware storage and over-the-air update retention.

For engineers reviewing the S29AL016J70BFI023 datasheet, S29AL016J70BFI023 pinout, S29AL016J70BFI023 application, or S29AL016J70BFI023 equivalent, key selection criteria include boot-block configuration (top/bottom), sector protection granularity, CFI compliance for host auto-configuration, and RY/BY# hardware status signaling for real-time erase/program monitoring.

Technical Context

The S29AL016J70BFI023 implements JEDEC-standard single-power-supply Flash command set with embedded algorithms for program (hot electron injection) and erase (Fowler-Nordheim tunneling). It supports both x8 and x16 data bus widths via BYTE# pin control and features dual power-saving modes: automatic sleep (0.2 µA) and standby (0.2 µA).

Hardware protection includes VCC detector for write inhibition during power transitions, WP#-controlled boot-sector lock, and RESET#-initiated state-machine reset. Erase suspend/resume enables background read/program in non-erasing sectors, while CFI provides standardized device identification for host software reconfiguration.

FAQ

Is S29AL016J70BFI023 pin-compatible with earlier S29AL016D devices?

Yes - the S29AL016J70BFI023 maintains identical pinout and software command compatibility with the 200 nm S29AL016D, enabling drop-in replacement in existing designs while delivering improved 110 nm process benefits including lower power and higher reliability.

What boot configuration does S29AL016J70BFI023 support?

The device supports both top-boot and bottom-boot configurations determined by factory programming; the boot sector (16 KB) is protected by WP# at VIL, and its location (first or last sector) is fixed per unit and documented in the device's autoselect mode output.

How is the Secured Silicon Sector programmed and locked?

The 128-word Secured Silicon Sector is programmed via a dedicated command sequence (enter secured silicon mode → program → lock); it can be factory-programmed with a unique 16-byte electronic serial number and permanently locked, or left unprogrammed for customer customization during final test.

Does S29AL016J70BFI023 require external high-voltage programming?

No - the device operates exclusively from a single 3.0 V supply (2.7–3.6 V range); all program and erase functions use internally generated and regulated high voltages, eliminating need for external VPP or 5 V sources in system design or production programming.
