Infineon Technologies S29AL016J70FFI020

Overview

S29AL016J70FFI020 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 hardware write protection via WP#, and is used in automotive engine control units for secure boot code storage.

For engineers reviewing the S29AL016J70FFI020 datasheet, S29AL016J70FFI020 pinout, S29AL016J70FFI020 application, or S29AL016J70FFI020 equivalent, key selection criteria include boot-block configuration (top/bottom), sector protection granularity, CFI compliance for host auto-configuration, erase suspend capability for real-time firmware updates, and RY/BY# hardware status signaling.

Technical Context

The S29AL016J70FFI020 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 (DQ7–DQ0) and word (DQ15–DQ0) data widths, selectable via BYTE# pin. Sector group protection is enforced by hardware lock bits, and temporary unprotect enables field code patching without full sector unlock - critical for over-the-air update workflows in automotive ECUs.

FAQ

What package type does S29AL016J70FFI020 use?

S29AL016J70FFI020 uses the 48-ball Fine-pitch BGA (VBK048) package with 0.8 mm ball pitch and 8.15 mm × 6.15 mm body size. This package is explicitly listed in Infineon's ordering information table for the "FFI020" suffix and confirmed in the mechanical drawings on page 52 of datasheet 002-00777 Rev. *Q.

Does S29AL016J70FFI020 support both x8 and x16 data bus modes?

Yes - the device supports byte-wide (x8) operation on DQ7–DQ0 and word-wide (x16) operation on DQ15–DQ0, selected by the BYTE# pin. In x16 mode, A-1 is multiplexed onto DQ15, enabling full 1M-word addressing. This dual-mode capability is defined in Section 7.1 of the datasheet and verified in the connection diagrams.

How is hardware write protection implemented on this device?

Hardware write protection is implemented via the WP# pin, which locks the boot sector (first or last 16 KB depending on top/bottom configuration) when driven low. This protection applies to both program and erase operations and remains active across power cycles. The function is detailed in Section 7.10 and confirmed in the AC characteristics table (tWLWH, tWHWL) on page 47.

Is the Secured Silicon Sector programmable after shipment from the factory?

Yes - the Secured Silicon Sector (128 words / 256 bytes) can be programmed and locked either at the factory or by the customer using the documented command sequence (Section 10.4). Once locked, it cannot be unlocked or reprogrammed, providing permanent device identification. This behavior is specified in Section 8.2 and validated in production test flow documentation.
