Product details

Overview

S29AL016J70FFI023 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 V_CC, features Secured Silicon Sector with 128-word ESN, and is used for automotive boot code storage and industrial firmware retention.

For engineers reviewing the S29AL016J70FFI023 datasheet, S29AL016J70FFI023 pinout, S29AL016J70FFI023 application, or S29AL016J70FFI023 equivalent, key selection criteria include boot-block configuration (top/bottom), sector protection granularity, CFI compliance for host auto-configuration, erase suspend/resume capability, and RY/BY# hardware status signaling - all critical for real-time embedded firmware updates and secure boot validation.

Technical Context

The S29AL016J70FFI023 implements a command-register-driven state machine for Embedded Erase and Embedded Program algorithms, eliminating external high-voltage requirements. It uses Fowler-Nordheim tunneling for erase and hot electron injection for program operations, with internal voltage regulation for VPP generation.

Its dual-mode interface supports byte-wide (DQ7–DQ0) and word-wide (DQ15–DQ0) data paths, selectable via BYTE# pin. Hardware features include dedicated RY/BY#, RESET#, and WP# pins for real-time operation monitoring, system reset synchronization, and boot-sector write protection - enabling deterministic timing in safety-critical automotive microcontroller boot sequences.

FAQ

What boot sector configuration does S29AL016J70FFI023 support?

The S29AL016J70FFI023 supports both top-boot and bottom-boot configurations, selected at manufacturing. The WP# pin protects the first or last 16 KB sector accordingly. Configuration is fixed per part number and cannot be changed in-system; refer to ordering code suffixes (e.g., 'T' = top-boot, 'B' = bottom-boot) in the Infineon datasheet section 6.1.

How is the Secured Silicon Sector programmed and locked?

The Secured Silicon Sector (128 words) is programmed using the standard Word Program command sequence at addresses 0x00000000–0x000000FF. Locking is performed via the Sector Protect command; once locked, it cannot be unlocked. Factory programming and locking occur during wafer sort or final test - customer locking requires issuing the Protect command after programming and verifying contents.

Does S29AL016J70FFI023 require external high-voltage for erase or program?

No. The S29AL016J70FFI023 operates exclusively from a single 2.7–3.6 V V_CC supply. All erase and program voltages (including VPP) are generated internally via on-chip charge pumps. No external 12 V or 5 V sources are needed, simplifying power design and enabling direct connection to 3.3 V microcontroller buses.

What is the function of the BYTE# pin in x8 vs. x16 mode?

When BYTE# is driven low, the device operates in x8 mode: DQ[7:0] carry data, and DQ15 functions as address bit A–1. When BYTE# is high, it operates in x16 mode: DQ[15:0] carry data. This pin must be statically set at power-up and cannot be toggled during operation - correct configuration is essential for address/data alignment with the host processor bus.
