Product details

Overview

S29AL016J55BFNR10 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 S29AL016J55BFNR10 datasheet, S29AL016J55BFNR10 pinout, S29AL016J55BFNR10 application, or S29AL016J55BFNR10 equivalent, key selection criteria include boot-block configuration (top/bottom), sector protection granularity, CFI compliance for host auto-configuration, and RY/BY# hardware status signaling for real-time erase/program monitoring.

Technical Context

The S29AL016J55BFNR10 implements a JEDEC-compliant single-power-supply Flash command set with embedded algorithms for program (hot electron injection) and erase (Fowler-Nordheim tunneling). It integrates a state machine that latches addresses/data internally and manages timing, verification, and margin checking without external intervention.

Hardware features include dedicated RY/BY# for cycle completion detection, RESET# for immediate operation abort and array read recovery, and WP# for boot-sector lock at V_IL. Sector group protection supports both permanent and temporary unprotect modes, enabling safe field firmware updates while preserving critical boot code.

Key Specifications

Parameter	Value and Actual Design Meaning

Pinout & Package

Package: 48-ball Fine-pitch BGA (VBK048, 0.8 mm pitch, 8.15 mm × 6.15 mm).

Pin/Terminal	Circuit Role	Design Meaning
A0–A19	Address Inputs	20-bit address bus supporting full 2M-byte addressing; A-1 (DQ15) used as byte/word mode indicator in x16 configuration.
DQ0–DQ15	Data I/O (x16) / DQ0–DQ7 (x8)	Bidirectional data bus; BYTE# pin selects x8/x16 mode; DQ6/DQ7 provide toggle/polling status during operations.
CE#, OE#, WE#	Chip, Output, Write Enable Controls	Independent enables eliminate bus contention; CE# gating reduces power during idle; OE#/WE# timing determines read/write window validity.
RY/BY#	Ready/Busy Output	Active-low open-drain signal indicating active program/erase; used for hardware flow control without polling overhead.
WP#	Write Protect Input	Hardware lock for boot sector (16 KB); asserted at V_IL to prevent accidental overwrite of startup code during system reset.
RESET#	Hardware Reset Input	Aborts all operations and forces device into read mode; synchronizes boot sequence with MCU reset assertion.

Key Features

Feature	Design Value
CFI (Common Flash Interface)	Enables host software to auto-detect device geometry, sector map, and command set-eliminating hardcoded Flash drivers in bootloader firmware.
Erase Suspend/Resume	Allows interruption of background erase to service real-time read/write requests in non-erasing sectors-critical for deterministic response in safety-critical ECUs.
Secured Silicon Sector	128-word factory-programmable serial number region locked independently-used for ECU unique ID binding and cryptographic key derivation.
Unlock Bypass Mode	Reduces multi-byte programming time by 50% (2-cycle vs. 4-cycle command sequence)-accelerates field firmware installation and diagnostics.
Flexible Boot Configuration	Top or bottom 16 KB boot block selectable via hardware strapping or command-supports legacy BIOS-style or modern UEFI-style boot partitioning.

Applications

Automotive Engine Control Unit (ECU)

Industrial PLC Firmware Storage

Use Scenario: Storing calibrated fuel injection maps and real-time diagnostic routines in an ISO 26262 ASIL-B compliant powertrain controller.

IC Role / Device Role / Timing Role: Non-volatile boot memory providing deterministic <55 ns instruction fetch latency during cold start and fail-safe recovery.

Use Value: AEC-Q100 Grade 1 rating and 1M-cycle endurance ensure reliable operation over 15-year vehicle life with repeated reprogramming during recalls or OTA updates.

Use Scenario: Holding ladder logic firmware and I/O configuration data in a DIN-rail mounted programmable logic controller operating in factory ambient (–40°C to +85°C).

IC Role / Device Role / Timing Role: Field-upgradable firmware store with hardware WP# protection against spurious writes during brown-out events.

Use Value: Sector group protection isolates runtime code from configuration sectors, preventing corruption during partial firmware updates.

Telematics Control Unit (TCU)

Medical Imaging System Boot ROM

Use Scenario: Secure boot loader storage in a cellular-connected TCU handling GNSS, CAN FD, and Wi-Fi firmware partitions.

IC Role / Device Role / Timing Role: CFI-compliant Flash enabling dynamic driver loading for multiple modem variants without board redesign.

Use Value: Secured Silicon Sector stores device-specific IMEI binding and TLS root certificates-tamper-resistant via factory lock.

Use Scenario: Storing FDA-certified boot firmware and DICOM protocol stack in a Class II medical imaging device requiring traceable firmware revision history.

Use Value: Erase suspend/resume allows concurrent diagnostic logging to RAM while background firmware validation runs-no service interruption.

Equivalent & Alternatives

The following parts are listed as comparable options for similar boot sector Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL016S55TFV10	45 nm process, 55 ns access, 16 Mbit, but uses different sector architecture (eight 8 KB + 256 KB uniform blocks) and lacks Secured Silicon Sector.	No factory-programmable serial number; requires external secure element for device identity binding.	Select when cost-per-bit optimization outweighs need for on-chip secure ID; verify CFI descriptor compatibility before firmware porting.
MX29LV160ETTI-55G	16 Mbit, 55 ns, 3.0 V, top-boot only; no CFI support; lower endurance (100K cycles); no erase suspend/resume.	Limited to fixed boot configuration; unsuitable for field-upgradeable safety-critical systems requiring background erase.	Acceptable for cost-sensitive consumer electronics where AEC-Q100 compliance and advanced features are not required.

Compared with S29AL016J55BFNR10, the S29GL016S55TFV10 offers higher density efficiency but sacrifices secure identity and flexible sector protection, while the MX29LV160ETTI-55G lacks critical automotive-grade reliability features and real-time operational flexibility.

FAQ

Is S29AL016J55BFNR10 pin-compatible with earlier S29AL016D devices?

Yes-S29AL016J55BFNR10 is fully pin- and software-compatible with the 200 nm S29AL016D, as confirmed in the Infineon datasheet (Rev. *Q, p. 1). The 110 nm process improves power efficiency and thermal performance without altering package footprint or signal mapping.

What boot configurations does S29AL016J55BFNR10 support?

S29AL016J55BFNR10 supports both top-boot and bottom-boot configurations. The boot sector location (first or last 16 KB) is determined by hardware strapping of the BYTE# pin during power-up, as specified in Section 7.3 of the datasheet.

Does S29AL016J55BFNR10 require external high-voltage programming?

No-S29AL016J55BFNR10 operates exclusively from a single 3.0 V supply (2.7–3.6 V range). Internally generated voltages handle all program and erase functions; no 5 V or 12 V VPP is needed, enabling direct connection to standard microcontroller buses.

How is the Secured Silicon Sector programmed and protected?

The Secured Silicon Sector (128 words) is programmed using a dedicated command sequence (Section 10.4) and locked either at factory (permanent) or by customer via software command. Once locked, it cannot be erased or rewritten-ensuring tamper-proof storage of serial numbers or cryptographic keys.
