Product details
Overview
S29AL008J70TFI013 from Infineon Technologies (formerly Cypress) is an 8-Mbit, 3.0 V-only boot sector Flash memory organized as 1 M × 8-bit or 512 K × 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 fifteen 64 KB sectors - deployed in automotive engine control units for firmware storage and over-the-air update retention.
For engineers reviewing the S29AL008J70TFI013 datasheet, S29AL008J70TFI013 pinout, S29AL008J70TFI013 application, or S29AL008J70TFI013 equivalent, key selection criteria include boot-block configuration (top/bottom), sector protection granularity, CFI compliance for host auto-configuration, and RY/BY#/DQ7 polling support for real-time operation status monitoring.
Technical Context
The S29AL008J70TFI013 implements a command-register-driven state machine for embedded erase and program algorithms, supporting JEDEC-standard single-power-supply Flash command sets including unlock bypass, sector erase suspend/resume, and autoselect mode. It uses Fowler-Nordheim tunneling for erase and hot electron injection for programming.
Hardware features include dedicated RY/BY# for cycle completion signaling, RESET# for immediate state-machine reset to read mode, and WP# for hardware-level boot-sector write protection. Sector group protection operates independently of software commands and persists across power cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (1,048,576 × 8 or 524,288 × 16), enabling full MCU boot code + parameter storage in single device |
| Access Time (tACC) | 55 ns max - supports zero-wait-state interface with 18 MHz microcontrollers |
| Voltage Range | 2.7 V to 3.6 V - compatible with Li-ion battery systems and automotive 3.3 V rails without level shifting |
| 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 - sufficient for frequent firmware update logging in telematics modules |

Pinout & Package
Package: 48-ball Fine-pitch BGA (VBK048), 8.15 mm × 6.15 mm × 1.00 mm, 0.8 mm ball pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting full 1 Mbyte addressing in byte mode or 512 Kword in word mode |
| DQ0–DQ14 | Data I/O (x16) | 15-bit bidirectional data bus; DQ15/A-1 serves dual role as MSB data or LSB address depending on BYTE# state |

| CE#, OE#, WE# | Control Enables | Independent chip/output/write enables eliminate bus contention and support interleaved read/write operations |
| RY/BY# | Ready/Busy Output | Active-low open-drain signal indicating active program/erase - used for hardware flow control without polling |
| WP# | Write Protect Input | Hardware lock for top or bottom 16 KB boot sector; internal pull-up allows default VIH when unconnected |
| RESET# | Hardware Reset | Asynchronous reset to read mode - synchronizes boot firmware fetch after system power-up or brownout recovery |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-programmable region with 8-word electronic serial number for secure device identification |
| Erase Suspend/Resume | Enables background erase: pause erase to read/program non-target sectors, then resume - essential for real-time firmware patching |
| Unlock Bypass Mode | Reduces multi-word programming time by 50% vs standard command sequence (2 writes instead of 4 per word) |
| CFI Compliance | Provides standardized register map for automatic host detection of geometry, timing, and command set - eliminates hard-coded driver assumptions |
| Automatic Sleep Mode | Enters 0.2 µA sleep after address stability timeout - reduces quiescent power in parked-vehicle monitoring circuits |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Firmware Storage |
|---|---|
|
Use Scenario: Stores boot firmware, calibration maps, and diagnostic logs in diesel engine management systems requiring AEC-Q100 Grade 1 qualification. IC Role / Device Role / Timing Role: Non-volatile boot memory with hardware write protection on first 16 KB sector to prevent corruption during power loss. Use Value: 55 ns access enables direct execution from Flash (XIP) on Cortex-M7 cores; 1M-cycle endurance supports daily ECU reprogramming over 10+ years. |
Use Scenario: Holds field-upgradable ladder logic firmware and I/O configuration tables in modular industrial controllers operating in harsh factory environments. IC Role / Device Role / Timing Role: Sector-erasable Flash with temporary unprotect capability - allows runtime patching of logic blocks without full chip erase. Use Value: CFI interface enables generic bootloader support across multiple PLC models; 2.7–3.6 V range accommodates wide-input DC-DC converters. |
| Telematics Control Unit (TCU) | Smart Gateway Boot Memory |
|
Use Scenario: Stores OTA update staging area and secure boot keys in cellular-connected vehicle gateways with persistent connectivity requirements. IC Role / Device Role / Timing Role: Secured Silicon Sector holds immutable cryptographic keys; RY/BY# enables deterministic interrupt latency during firmware validation. Use Value: 20-year data retention guarantees key integrity over vehicle lifetime; 0.2 µA sleep current extends battery backup duration during network outages. |
Use Scenario: Primary boot device for multi-core automotive gateways managing CAN FD, Ethernet AVB, and LIN communication stacks. IC Role / Device Role / Timing Role: Top-boot configuration stores primary bootloader; WP# pin physically tied to chassis ground for permanent protection. Use Value: Dual-mode (x8/x16) interface simplifies migration between legacy 8-bit and new 16-bit bus architectures; TSOP/BGA package options support both cost- and space-constrained designs. |
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 |
|---|---|---|---|
| S29AL008J70TFI020 | Same die, 70 ns access time (vs. 55 ns), identical sector map and command set | Targeted at cost-sensitive industrial applications where 18 MHz bus timing margin is acceptable | Select when system clock < 14 MHz and extended temperature range is not required |
| MX29LV008CTTI-70G | 8 Mbit, 3.0 V, 70 ns, but lacks CFI support and secured silicon sector; different sector architecture (one 16 KB + thirty-one 64 KB) | Used in legacy consumer electronics where host firmware does not require auto-detection or secure ID | Choose only if migrating from existing MX29LV design; not suitable for AEC-Q100 or secure boot use cases |
Compared with S29AL008J70TFI020, the 55 ns version enables higher-speed microcontroller interfaces; versus MX29LV008CTTI-70G, it adds CFI, secured silicon, and automotive qualification - making it the sole option for new AEC-Q100-compliant designs requiring field-upgradable secure firmware.

FAQ
Is S29AL008J70TFI013 pin-compatible with earlier S29AL008D devices?
Yes - the S29AL008J70TFI013 maintains identical pinout and software command compatibility with the S29AL008D, including TSOP and BGA packages. It is manufactured on 110 nm process technology while retaining full functional equivalence and JEDEC compliance, enabling drop-in replacement without PCB or firmware changes.
What is the function of the BYTE# pin, and how does it affect data bus width?
The BYTE# pin selects between 8-bit (BYTE# = VIH) and 16-bit (BYTE# = VIL) data bus configurations. In byte mode, DQ7–DQ0 carry data and A-1 is input on DQ15; in word mode, DQ15–DQ0 carry full 16-bit data. This dual-mode flexibility supports migration between legacy 8-bit microcontrollers and modern 16-bit bus architectures.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region programmed via unique command sequences and optionally locked at factory or by customer. It contains a factory-assigned 8-word electronic serial number and supports permanent write-protection - unlike standard sectors, it cannot be erased by chip or sector erase commands once locked.
Can WP# protect sectors other than the boot block?
No - WP# only protects the top or bottom 16 KB boot sector, depending on the device's top/bottom boot configuration. Protection of other sectors requires software-based sector group protection commands or hardware locking via programming equipment; WP# has no effect on non-boot sectors.
