Product details
Overview
S29AL016J70BFI020 from Infineon Technologies (formerly Cypress) is a 16-Mbit, 3.0 V-only boot sector Flash memory organized as 2 M × 8-bit or 1 M × 16-bit, featuring 55 ns access time, AEC-Q100 Grade 1 (–40°C to +125°C), and flexible sector architecture with one 16 KB, two 8 KB, one 32 KB, and thirty-one 64 KB sectors. It serves as nonvolatile firmware storage in automotive engine control units requiring secure, in-system reprogrammability.
For engineers reviewing the S29AL016J70BFI020 datasheet, S29AL016J70BFI020 pinout, S29AL016J70BFI020 application, or S29AL016J70BFI020 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 S29AL016J70BFI020 implements a command-register-driven state machine that executes embedded algorithms for program (hot electron injection) and erase (Fowler-Nordheim tunneling), eliminating external high-voltage requirements. It supports both x8 and x16 data bus widths via BYTE# pin control and integrates dedicated hardware features including WP# for boot-sector write protection and RESET# for immediate operation abort and array read recovery.
Its sector group protection operates independently per sector, enabling selective locking via hardware or software commands, while Erase Suspend/Erase Resume allows concurrent read/program operations in unselected sectors-enabling true background erase in real-time firmware update scenarios without halting system execution.
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 size capacity for ECUs and industrial controllers. |
| Access Time (tACC) | 55 ns - enables zero-wait-state operation with 18 MHz microcontrollers in safety-critical automotive applications. |
| Supply Voltage Range | 2.7 V to 3.6 V - supports single-supply battery-powered systems without level-shifting or auxiliary regulators. |
| Cycling Endurance | 1,000,000 cycles per sector - ensures field-upgradeable firmware retains integrity over full vehicle lifetime (15+ years). |
| Data Retention | 20 years typical at +125°C - guarantees stored calibration data and boot code persistence under extended high-temperature stress. |
| Operating Temperature | AEC-Q100 Grade 1 (–40°C to +125°C) - qualified for under-hood automotive environments without derating. |
| Power Consumption | 0.2 µA standby current - minimizes quiescent drain in always-on vehicle modules during sleep mode. |
Pinout & Package
Package: 48-ball Fine-pitch BGA (VBK048, 0.8 mm pitch, 8.15 mm × 6.15 mm). Pinout validated 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 2 Mbyte addressing in byte mode; A-1 used only in word mode for DQ15/A-1 multiplexing. |
| DQ0–DQ15 | Data I/O (x16) / DQ0–DQ7 (x8) | Bidirectional data bus; BYTE# pin selects x8/x16 width - critical for compatibility with 8-bit vs. 16-bit microcontroller buses. |
| CE#, OE#, WE# | Chip, Output, Write Enable | Independent controls eliminate bus contention; CE# gating reduces power during idle; OE#/WE# timing defines read/write cycle boundaries. |
| RY/BY# | Ready/Busy Output | Active-low open-drain signal indicating internal operation status - enables hardware-synchronized polling without software overhead. |
| WP# | Write Protect Input | Hardware lock for boot sector (16 KB); low-level assertion prevents accidental firmware overwrite during power transients or reset glitches. |
| RESET# | Hardware Reset Input | Aborts ongoing erase/program and forces device into read mode - synchronizes boot sequence with MCU reset assertion. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-programmable region with 8-word electronic serial number - enables unique device identification and anti-cloning in Tier-1 automotive supply chains. |
| Unlock Bypass Program Mode | Reduces programming time by 50% versus standard command sequence (2 writes vs. 4) - accelerates over-the-air firmware patch deployment. |
| Erase Suspend/Resume | Pauses erase to service interrupt-driven reads/writes in other sectors - maintains deterministic latency in real-time control loops during firmware updates. |
| CFI Compliance | Standardized JEDEC interface providing device geometry, timing, and command set descriptors - eliminates hardcoded Flash drivers across multiple MCU platforms. |
| Automatic Sleep Mode | Enters 0.2 µA sleep after address stability timeout - extends battery life in telematics modules operating on backup power for >10 years. |

FAQ
What boot configuration does S29AL016J70BFI020 support?
The S29AL016J70BFI020 supports both top-boot and bottom-boot configurations, selected via hardware strapping or software command. The boot sector (16 KB) resides at the highest or lowest address range respectively, enabling flexible fail-safe recovery strategies in automotive ECUs where firmware rollback must be architecturally guaranteed.
How does the Secured Silicon Sector function in practice?
The Secured Silicon Sector is a dedicated 256-byte region containing an 8-word electronic serial number programmed at factory or by customer. It is permanently locked via hardware fuse or software command, preventing overwrite even during full chip erase. This enables cryptographic binding of firmware images to specific hardware units in regulated medical and automotive applications.
Is S29AL016J70BFI020 compatible with standard EPROM programmers?
Yes - the S29AL016J70BFI020 supports programming in standard EPROM programmers using its command-set-compatible interface. No 12 V VPP or 5 V VCC is required; all operations execute from the single 3.0 V supply, maintaining compatibility with legacy programming infrastructure while eliminating high-voltage circuitry on target boards.
What is the role of the BYTE# pin in x8/x16 mode selection?
The BYTE# pin configures data bus width: logic high selects x16 mode (DQ15–DQ0 active), logic low selects x8 mode (DQ7–DQ0 active). This pin must be stable before power-up and remains latched during operation - enabling single hardware design to support both 8-bit and 16-bit microcontroller interfaces without board redesign.
