Product details
Overview
S29AL016J55TFNR20 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 - used for firmware storage and boot code execution in automotive engine control units.
For engineers reviewing the S29AL016J55TFNR20 datasheet, S29AL016J55TFNR20 pinout, S29AL016J55TFNR20 application, or S29AL016J55TFNR20 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 S29AL016J55TFNR20 implements a command-register-driven state machine supporting JEDEC-standard single-power-supply Flash operations: Embedded Erase and Embedded Program algorithms handle internal timing, voltage generation, and margin verification without external high-voltage supplies. It supports both x8 and x16 data bus widths via BYTE# pin control.
Hardware features include dedicated RY/BY# for cycle completion detection, RESET# for immediate state-machine reset to read mode, and WP# for hardware-level boot-sector write protection. Sector Group Protection enables in-system locking/unlocking of individual sectors, augmented by Temporary Unprotect for field code updates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2,097,152 × 8-bit or 1,048,576 × 16-bit) - defines firmware image capacity for ECUs and industrial controllers. |
| Access Time | 55 ns (max) - enables zero-wait-state operation with 18 MHz microcontrollers. |
| Supply Voltage | 2.7 V to 3.6 V - supports battery-backed systems and wide-input DC-DC rails without level-shifting. |
| Cycling Endurance | 1,000,000 erase/program cycles per sector - ensures long-term field reliability in over-the-air update scenarios. |
| Data Retention | 20 years (typical) at +125°C - validated for automotive under-hood applications across full lifecycle. |
| Operating Temp | –40°C to +125°C (AEC-Q100 Grade 1) - qualified for powertrain and ADAS domain controllers. |
| Power Consumption | 0.2 µA standby/auto-sleep current - critical for always-on vehicle modules with strict quiescent current budgets. |
Pinout & Package
Package: 48-ball Fine-pitch BGA (VBK048, 0.8 mm pitch, 8.15 mm × 6.15 mm). Pinout defined per Infineon Document 002-00777 Rev. *Q, Figure 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 2M-byte addressing in byte mode or 1M-word in word mode. |
| DQ0–DQ15 | Data I/O (x16) / DQ0–DQ7 (x8) | Bidirectional data bus; BYTE# pin selects x8/x16 width - enables compatibility with 8-bit and 16-bit microcontrollers. |
| CE#, OE#, WE# | Chip, Output, Write Enable | Independent control lines eliminate bus contention and support interleaved read/write in multi-device systems. |
| RY/BY# | Ready/Busy Output | Active-low open-drain signal indicates active erase/program - allows hardware interrupt-driven status polling. |
| RESET# | Hardware Reset Input | Asynchronous reset to read mode - synchronizes boot firmware fetch after system power-up or brownout recovery. |
| WP# | Write Protect Input | Hardware lock for boot sector (16 KB); tied low to prevent accidental overwrite of startup code during runtime. |
Key Features
| Feature | Design Value |
|---|---|
| CFI Compliance | Enables host software to auto-detect device geometry, sector map, and command set - eliminates hard-coded Flash drivers. |
| Erase Suspend/Resume | Pauses ongoing sector erase to service urgent read/program requests in other sectors - enables true background firmware updates. |
| Secured Silicon Sector | 128-word factory-programmable serial number region - provides immutable device identity for secure boot and anti-counterfeiting. |
| Unlock Bypass Mode | Reduces program command overhead from 4 to 2 write cycles - cuts total firmware patch time by ~35% in field update workflows. |
| Flexible Boot Configuration | Top or bottom 16 KB boot block selectable via hardware strapping - supports legacy BIOS-style or modern UEFI-style boot partitioning. |

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 |
|---|---|---|---|
| S29GL016S55TFIR20 | 16 Mbit MirrorBit® NOR Flash; 55 ns access; 3.0 V supply; 64-ball Fortified BGA only - no TSOP or 48-ball BGA option. | Higher endurance (100K cycles vs. 1M) but lacks Secured Silicon Sector and CFI compliance. | Select when BGA-only footprint and lower cost outweigh need for serial number security and host auto-configuration. |
| MX29LV160ETTI-70G | 16 Mbit, 3.0 V, 70 ns access; 48-pin TSOP; no AEC-Q100 qualification; no Erase Suspend or Unlock Bypass. | Limited to industrial temp (–40°C to +85°C); lacks automotive-grade reliability and advanced program efficiency features. | Choose only for cost-sensitive non-automotive designs where 70 ns latency and absence of suspend/resume are acceptable. |
Compared with S29GL016S55TFIR20 and MX29LV160ETTI-70G, the S29AL016J55TFNR20 uniquely combines AEC-Q100 Grade 1 qualification, CFI compliance, Secured Silicon Sector, and Erase Suspend - making it the sole option for safety-critical automotive boot memory requiring field-upgradability and traceability.

FAQ
Is S29AL016J55TFNR20 pin-compatible with earlier S29AL016D variants?
Yes - the S29AL016J55TFNR20 maintains identical pinout and software command compatibility with the S29AL016D, including CE#, OE#, WE#, RY/BY#, and RESET# signal behavior. The 110 nm process improves power efficiency and thermal performance while preserving mechanical and electrical interface integrity for drop-in replacement in existing designs.
What boot configuration does the 'T' in S29AL016J55TFNR20 indicate?
The 'T' denotes Top Boot Block configuration: the protected 16 KB boot sector resides at the highest address range (0xFFE000–0xFFFFFF in byte mode), allowing microcontrollers to execute startup code from upper memory immediately after reset - standard for ARM Cortex-M and Power Architecture-based ECUs.
Does S29AL016J55TFNR20 support both x8 and x16 data bus modes?
Yes - the BYTE# pin selects bus width: driven low for x8 mode (DQ0–DQ7 active), high for x16 mode (DQ0–DQ15 active). This dual-mode capability enables reuse across 8-bit microcontrollers (e.g., legacy 8051 derivatives) and 16-bit processors (e.g., Renesas RH850) without PCB redesign.
How is the Secured Silicon Sector programmed and locked?
The 128-word Secured Silicon Sector is programmed using the Enter/Exit Secured Silicon Sector command sequence (documented in Section 10.4 of Infineon 002-00777 Rev. *Q). Locking is performed via the Sector Protect command; once locked, the sector becomes permanently read-only unless unlocked using the factory-specific password - preventing unauthorized modification of the embedded electronic serial number.
