Infineon Technologies S29AL016J70BFA013

Overview

S29AL016J70BFA013 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. 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 boot code storage.

For engineers reviewing the S29AL016J70BFA013 datasheet, S29AL016J70BFA013 pinout, S29AL016J70BFA013 application, or S29AL016J70BFA013 equivalent, key selection criteria include boot-block configuration (top/bottom), sector protection granularity, CFI compliance for host auto-reconfiguration, erase suspend/resume capability, and BGA/TSOP package compatibility with legacy PCB layouts.

Technical Context

The device implements JEDEC-standard single-power-supply Flash command sets with embedded algorithms for program (hot electron injection) and erase (Fowler-Nordheim tunneling). Its internal state machine latches addresses/data during write cycles and verifies cell margin post-operation.

Hardware features include a low-VCC detector for power-transition write inhibition, dedicated RY/BY# pin for cycle completion detection, and WP# pin that protects the first or last 16 KB sector depending on boot configuration. Sector group protection supports both permanent lock and temporary unprotect modes.

FAQ

What does the "BFA013" suffix indicate in S29AL016J70BFA013?

The "BFA013" suffix specifies the 48-ball Fine-pitch BGA package (VBK048), RoHS-compliant finish, and tape-and-reel packaging format. "BF" denotes fine-pitch BGA, "A" indicates lead-free plating, and "013" identifies the specific reel size and orientation per Infineon's ordering convention.

Does S29AL016J70BFA013 support both x8 and x16 data bus widths?

Yes. The device operates in either byte (x8) or word (x16) mode, selected by the BYTE# pin. In x8 mode, DQ7–DQ0 carry data and DQ15 functions as A−1; in x16 mode, DQ15–DQ0 are fully active, enabling 16-bit microprocessor interfacing without external data multiplexing.

How is sector protection implemented, and can it be changed after locking?

Sector protection is enforced via hardware lock bits set by command sequences. Once permanently locked, sectors cannot be unlocked-but the Temporary Sector Unprotect feature allows transient unlocking for updates. This requires issuing a specific unlock command before programming/erasing, then relocking afterward to restore protection.

Is the Secured Silicon Sector pre-programmed and locked at the factory?

No. The 256-byte Secured Silicon Sector is blank at shipment. It may be programmed and locked either at the factory (for OEM serialization) or by the end customer using standard command sequences. Locking is irreversible once executed, ensuring permanent device identity and security.
