Product details

Overview

S29AL016J70BFA010 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 operates across 2.7–3.6 V, supports in-system programming without high-voltage VPP, and is used for automotive engine control firmware storage.

For engineers reviewing the S29AL016J70BFA010 datasheet, S29AL016J70BFA010 pinout, S29AL016J70BFA010 application, or S29AL016J70BFA010 equivalent, key selection criteria include boot-sector protection configuration (top/bottom), CFI compliance for host auto-configuration, erase suspend/resume capability for real-time firmware updates, and hardware write protection via WP# and RESET# pins.

Technical Context

The S29AL016J70BFA010 implements a command-register-driven state machine for embedded program/erase algorithms, using hot electron injection for programming and Fowler-Nordheim tunneling for erasure. It features dual-mode data bus (x8/x16) with BYTE# control and JEDEC-compliant software command set.

Hardware signaling includes RY/BY# for cycle completion detection, dedicated WP# for boot-sector lock, and RESET# for immediate operation termination and array read recovery. Sector group protection is implemented via on-chip logic that disables WE#/CE# paths to locked sectors regardless of command sequence.

FAQ

What does the 'BFA010' suffix indicate in S29AL016J70BFA010?

The 'BFA010' suffix identifies the specific packaging and marking variant: 'BF' denotes 48-ball Fine-pitch BGA (VBK048), 'A' indicates automotive temperature grade (–40°C to +125°C), and '010' is the assembly and test revision code. This matches Infineon's official ordering nomenclature in datasheet section 6.1.

Can S29AL016J70BFA010 be used in byte-mode (x8) and word-mode (x16) configurations on the same PCB?

Yes - the BYTE# pin selects bus width: driven low for x8 mode (DQ7–DQ0 active), high for x16 mode (DQ15–DQ0 active). The device internally remaps address lines accordingly, and both modes share identical command sequences and timing specifications per datasheet section 7.1.

How does the Secured Silicon Sector differ from standard Flash sectors?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region with factory-programmable electronic serial number and permanent lock capability. Unlike user sectors, it cannot be erased via standard commands; access requires a specific unlock sequence, and once locked, only read operations are permitted - ensuring immutable device identity.

Is hardware reset (RESET#) required for reliable boot behavior in automotive applications?

Yes - asserting RESET# forces immediate exit from any ongoing program/erase cycle and restores read-array state. In automotive ECUs, tying RESET# to the system power-on reset circuit ensures deterministic boot firmware fetch even after brownout or watchdog-triggered restart, preventing undefined instruction fetch from partially written sectors.
