Product details
Overview
S29AL016J55BFIR10 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 features including RY/BY#, RESET#, and WP# for automotive firmware storage.
For engineers reviewing the S29AL016J55BFIR10 datasheet, S29AL016J55BFIR10 pinout, S29AL016J55BFIR10 application, or S29AL016J55BFIR10 equivalent, key selection criteria include boot-sector protection granularity, CFI compliance for host auto-configuration, erase suspend/resume capability for real-time firmware updates, and dual-mode (x8/x16) data bus support in industrial and automotive control modules.
Technical Context
The device implements JEDEC-standard single-power-supply Flash command set with embedded algorithms for program and erase-automatically timing pulses and verifying cell margin. Its sector group protection uses dedicated WP# and software lock commands to secure boot code regions independently of main array sectors.
CFI compliance enables runtime identification of geometry, voltage, and timing parameters by host firmware; Erase Suspend allows interruption of background erase to service read/write requests in non-erasing sectors-critical for deterministic response in safety-critical ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2,097,152 × 8-bit or 1,048,576 × 16-bit) |
| Access Time | 55 ns maximum-enables zero-wait-state operation with 18 MHz microcontrollers |
| Supply Voltage | 2.7 V to 3.6 V-supports wide-range battery-powered systems without regulation overhead |
| Operating Temperature | –40°C to +125°C (AEC-Q100 Grade 1)-qualified for under-hood automotive applications |
| Erase Endurance | 1,000,000 cycles per sector-ensures long-term field update reliability in telematics modules |
| Data Retention | 20 years typical at +125°C-guarantees firmware integrity over full vehicle lifecycle |

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 |
|---|---|---|
| CE# | Chip Enable | Active-low chip select enabling memory access; must be asserted before OE#/WE# for valid read/write |
| OE# | Output Enable | Active-low control for data bus output driver-used to avoid bus contention during multi-device sharing |
| WE# | Write Enable | Active-low signal initiating command latching or data programming; synchronized with CE# and address setup |
| RY/BY# | Ready/Busy Output | Open-drain status indicator-low during active program/erase, high when ready for next command |
| RESET# | Hardware Reset | Active-low asynchronous reset that halts all operations and returns device to read mode-tied to system reset rail |
| WP# | Write Protect | Hardware lock for boot sector: low-level assertion protects first or last 16 KB depending on top/bottom boot configuration |
| BYTE# | Data Bus Width Select | Configures x8 (high) or x16 (low) operation-determines DQ0–DQ7 vs. DQ0–DQ15 data mapping |
| DQ0–DQ15 | Data I/O | Bidirectional data bus; in x8 mode, only DQ0–DQ7 are active; DQ15 functions as A−1 address bit in x16 mode |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word factory-programmable serial number region-enables unique device identification and anti-cloning in Tier 1 automotive modules |
| Unlock Bypass Program | Reduces multi-byte programming time by 50%-only two write cycles instead of four per byte/word |
| Erase Suspend/Resume | Allows real-time servicing of interrupt-driven reads/writes during background sector erase-essential for ASIL-B firmware patching |
| Flexible Boot Configuration | Selectable top or bottom 16 KB boot block-supports legacy BIOS-style or modern UEFI-style boot vector placement |
| Automatic Sleep Mode | Enters 0.2 µA sleep after address stability timeout-eliminates need for external power-gating logic in battery-backed gateways |

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 |
|---|---|---|---|
| S29GL016S55TFIR10 | 45 nm process, 48-pin TSOP only, no BGA option; 45 ns access time; lacks Secured Silicon Sector | No factory-programmable serial number; limited to non-security-critical industrial firmware | Select when higher speed and lower cost outweigh secure ID and package flexibility needs |
| MX29LV160ETTI-70G | 2.7–3.6 V, 70 ns access, 48-pin TSOP only; no CFI support; no Erase Suspend | Requires fixed host driver; cannot interrupt erase-unsuitable for real-time systems | Choose only for legacy designs with existing non-CFI firmware infrastructure and relaxed timing |

FAQ
Is S29AL016J55BFIR10 pin-compatible with earlier S29AL016D devices?
Yes-S29AL016J55BFIR10 maintains identical pinout and software compatibility with the 200 nm S29AL016D, as confirmed in the Infineon datasheet revision *Q. This enables drop-in replacement in existing designs while delivering improved performance, lower power, and enhanced security features including Secured Silicon Sector.
Does this device require external high-voltage circuitry for programming?
No-S29AL016J55BFIR10 operates exclusively from a single 2.7–3.6 V supply. All internal program and erase voltages are generated on-chip using charge pumps; no external 5 V or 12 V VPP is needed, simplifying board design and reducing BOM count in space-constrained automotive modules.
What is the function of the BYTE# pin, and how does it affect data bus operation?
BYTE# selects between x8 and x16 data bus width: high = byte mode (DQ0–DQ7 active), low = word mode (DQ0–DQ15 active). In word mode, DQ15 doubles as address bit A−1. This pin must be stable before CE# assertion and determines how the host processor maps memory addresses to data lines during read/write cycles.
How does the WP# pin protect the boot sector in top-boot versus bottom-boot configurations?
When WP# is driven low, it hardware-locks the boot sector-16 KB at either the highest address (top-boot) or lowest address (bottom-boot)-based on factory configuration. This protection is independent of software lock commands and remains active even during power cycling, preventing accidental overwrite of critical boot code in both automotive and industrial environments.
