Product details
Overview
S29AL016J70BFN020 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 12 V VPP required-and integrates hardware reset (RESET#), ready/busy (RY/BY#), and write-protect (WP#) for automotive boot code storage.
For engineers reviewing the S29AL016J70BFN020 datasheet, S29AL016J70BFN020 pinout, S29AL016J70BFN020 application, or S29AL016J70BFN020 equivalent, key selection criteria include boot-sector protection granularity, CFI compliance for host firmware auto-configuration, erase suspend/resume capability for real-time interrupt handling, and dual temperature grade support across industrial and automotive ECUs.
Technical Context
The S29AL016J70BFN020 implements a command-register-controlled state machine that executes embedded program/erase algorithms with automatic pulse timing and margin verification. Its architecture separates byte-mode (DQ7–DQ0) and word-mode (DQ15–DQ0) data paths using the BYTE# pin, enabling compatibility with both 8-bit and 16-bit microcontrollers.
Hardware features include a low-VCC detector for power-transition write inhibition, sector group protection lock/unlock via WP# and command sequences, and Erase Suspend/Erase Resume enabling background read/program operations in non-erasing sectors-critical for deterministic firmware updates in safety-critical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2,097,152 × 8-bit or 1,048,576 × 16-bit) - supports full boot image storage for mid-tier MCUs without external memory expansion. |
| Access Time (tACC) | 55 ns - enables zero-wait-state operation with 18 MHz+ microcontrollers in embedded control applications. |
| Supply Voltage | 2.7 V to 3.6 V - single-supply operation eliminates need for auxiliary voltage rails in battery-powered or automotive 3.3 V systems. |
| Cycling Endurance | 1,000,000 cycles per sector - supports field firmware updates over 10+ years in telematics or gateway modules. |
| Data Retention | 20 years typical - ensures long-term reliability of calibration data and boot code in unpowered storage conditions. |
| Operating Temperature | –40°C to +125°C (AEC-Q100 Grade 1) - qualified for under-hood automotive applications including engine control units. |
| Power Consumption | 0.2 µA standby current - minimizes quiescent drain in always-on vehicle subsystems such as CAN gateways. |
Pinout & Package
Package: 48-ball Fine-pitch BGA (VBK048), 0.8 mm pitch, 8.15 mm × 6.15 mm footprint.
| 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 addressing in word mode. |
| DQ0–DQ15 | Data I/O (x16) / DQ0–DQ7 (x8) | Bidirectional data bus; BYTE# pin selects 8-bit (DQ0–DQ7) or 16-bit (DQ0–DQ15) operation. |
| CE#, OE#, WE# | Chip Enable, Output Enable, Write Enable | Independent control signals eliminate bus contention and enable interleaved read/write in multi-device systems. |
| RY/BY# | Ready/Busy Output | Active-low open-drain signal indicates completion of program/erase cycles-enables hardware polling without software overhead. |
| RESET# | Hardware Reset Input | Asynchronous reset of internal state machine to read mode; ties directly to system reset for deterministic boot recovery. |
| WP# | Write Protect Input | Hardware lock for top/bottom 16 KB boot sector-prevents accidental overwrite of critical startup code during runtime. |
Key Features
| Feature | Design Value |
|---|---|
| CFI Compliance | Enables host firmware to auto-detect device geometry, timing, and command set-reducing BSP porting effort across Flash variants. |
| Erase Suspend/Resume | Allows interruption of sector erase to service high-priority reads or writes elsewhere-essential for real-time OS-based firmware updates. |
| Secured Silicon Sector | 128-word factory-programmable serial number region-supports secure device identification and anti-cloning in Tier 1 automotive supply chains. |
| Unlock Bypass Mode | Reduces sequential programming time by 50% (2-cycle vs. 4-cycle command sequence)-improves production line flash programming throughput. |
| Flexible Sector Protection | Hardware lock/unlock of individual sectors via WP# and command interface-enables selective firmware partitioning (e.g., bootloader vs. application). |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL016S70TFV10 | 16 Mbit, 3 V, 70 ns access, 64-ball Fortified BGA only - no TSOP or 48-ball BGA option; lacks Secured Silicon Sector. | Targeted at space-constrained designs where 9 mm × 9 mm BGA is acceptable; not suitable for secure device ID use cases. | Select when board layout prioritizes package robustness over secure serialization and boot-sector flexibility. |
| MX29LV160ETTI-70G | 16 Mbit, 3 V, 70 ns, TSOP-48 only - no BGA packages; supports top/bottom boot but no CFI or Erase Suspend. | Cost-sensitive industrial controls where firmware update frequency is low and host software does not require auto-configuration. | Select only for legacy TSOP-based designs lacking real-time update requirements or secure identity needs. |

FAQ
Is S29AL016J70BFN020 pin-compatible with earlier S29AL016D devices?
Yes, the S29AL016J70BFN020 is fully pin- and software-compatible with the S29AL016D, as confirmed in the datasheet's architectural advantages section. It is manufactured on 110 nm process technology while maintaining identical pinout, command set, and timing behavior-enabling drop-in replacement in existing designs without PCB or firmware changes.
What is the function of the BYTE# pin, and how does it affect data bus configuration?
The BYTE# pin selects between 8-bit (x8) and 16-bit (x16) data bus operation: when pulled high, DQ0–DQ7 are active for byte-wide access; when pulled low, DQ0–DQ15 operate as a word-wide bus. This dual-mode capability allows seamless integration with both 8-bit microcontrollers and 16-bit SoCs without external data multiplexing logic.
Does S29AL016J70BFN020 support hardware reset during active program/erase operations?
Yes, the RESET# pin provides asynchronous hardware reset functionality. When asserted, it terminates any ongoing program or erase operation and forces the device into read-array mode. This ensures safe recovery from power faults or watchdog timeouts without requiring software intervention or risking memory corruption.
How is sector protection implemented, and can locked sectors be temporarily unlocked?
Sector protection is implemented via hardware WP# pin control for the boot sector and command-based locking for all other sectors. Locked sectors block all program/erase commands until explicitly unlocked. The Temporary Sector Unprotect feature allows temporary unlocking of previously locked sectors-enabling code modification without permanent removal of protection settings.
