Infineon Technologies S29AL016J70BFI013

Overview

S29AL016J70BFI013 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 comprising one 16 KB, two 8 KB, one 32 KB, and thirty-one 64 KB sectors. It supports in-system programming via standard 3.0 V VCC-no 5 V or 12 V required-and integrates hardware reset (RESET#), ready/busy (RY/BY#), and write-protect (WP#) for automotive firmware storage.

For engineers reviewing the S29AL016J70BFI013 datasheet, S29AL016J70BFI013 pinout, S29AL016J70BFI013 application, or S29AL016J70BFI013 equivalent, key selection criteria include boot-sector protection granularity, CFI compliance for host auto-configuration, erase suspend/resume capability for real-time firmware updates, and dual temperature grade support across industrial and automotive ECUs.

Technical Context

The S29AL016J70BFI013 implements a command-register-driven state machine for embedded program/erase algorithms, using Fowler-Nordheim tunneling for erase and hot electron injection for programming. Its sector-group protection is enforced via hardware lock bits accessible through dedicated command sequences, and WP# pin behavior depends on boot configuration (top/bottom).

It features dual data-width operation (x8/x16), selectable via BYTE# pin, and supports both chip- and sector-erase modes with automatic pre-programming verification. Erase suspend allows concurrent read/program in non-erasing sectors, enabling true background operations without halting system execution.

FAQ

Is S29AL016J70BFI013 pin-compatible with earlier S29AL016D devices?

Yes-S29AL016J70BFI013 is fully pin- and software-compatible with the S29AL016D, as confirmed in the datasheet's "Architectural Advantages" section stating "Fully compatible with 200 nm S29AL016D." This includes identical TSOP and BGA footprints, command set, and timing parameters, enabling drop-in replacement without PCB redesign.

What is the function of the BYTE# pin, and how does it affect data bus width?

The BYTE# pin selects between x8 and x16 data bus configurations: when pulled low, the device operates in 16-bit mode with DQ15–DQ0 active; when high, it operates in 8-bit mode with DQ7–DQ0 active. This allows flexible integration with 8-bit microcontrollers or 16-bit DSPs without external data multiplexing logic.

Does S29AL016J70BFI013 support simultaneous read and erase operations?

No-it does not support true concurrent read-while-erase (RWE). However, Erase Suspend allows pausing an ongoing sector erase to perform reads or writes in *other* non-erasing sectors, then resuming the original erase. This provides deterministic foreground/background partitioning but not true parallelism.

How is the Secured Silicon Sector programmed and locked?

The Secured Silicon Sector (128 words) is programmed using a dedicated command sequence (Enter Secured Silicon Sector → Program → Exit Secured Silicon Sector), then permanently locked via a separate lock command. Locking can be performed at factory or by end customer; once locked, the sector becomes read-only and immune to standard erase commands.
