Product details

Overview

S29AL008J55BFIR10 from Infineon Technologies (formerly Cypress) is an 8 Mbit (1 M × 8-bit / 512 K × 16-bit), 3.0 V-only boot sector Flash memory with 55 ns access time, 2.7–3.6 V single-supply operation, and AEC-Q100 Grade 1 qualification (–40°C to +125°C). It features flexible sector architecture (one 16 KB, two 8 KB, one 32 KB, fifteen 64 KB sectors), Secured Silicon Sector with 128-word factory-programmable serial ID, and hardware write protection via WP# pin for boot-sector lockdown in automotive ECU firmware storage.

For engineers reviewing the S29AL008J55BFIR10 datasheet, S29AL008J55BFIR10 pinout, S29AL008J55BFIR10 application, or S29AL008J55BFIR10 equivalent, key selection criteria include boot-block configuration (top/bottom), CFI compliance for host auto-detection, erase suspend/resume capability for real-time firmware updates, and RY/BY# hardware status signaling for deterministic timing control in safety-critical embedded systems.

Technical Context

This device implements a command-register-controlled state machine that executes embedded program/erase algorithms-automatically timing Fowler-Nordheim tunneling erase pulses and hot-electron injection programming while verifying cell margin. It supports both x8 and x16 data bus configurations via BYTE# pin, with DQ15/A-1 serving dual role as MSB data or LSB address.

Hardware protection includes VCC detector disabling writes during power transitions, sector group locking via WP# and CE#/WE# sequences, and RESET#-driven hard reset to array-read mode. Erase suspend allows background read/program in non-erasing sectors-enabling true concurrent operations without halting system execution.

Key Specifications

Parameter	Value and Actual Design Meaning

WP#	Hardware write protect	Locks top or bottom 16 KB boot sector depending on configuration; internal pull-up ensures safe default state
RY/BY#	Ready/Busy output	Open-drain active-low signal indicating completion of program/erase - enables hardware-synchronized polling
RESET#	Hardware reset	Asynchronous active-low input forcing device into read-array mode - synchronizes boot firmware fetch after power-on or crash recovery

Key Features

Feature	Design Value
Erase Suspend/Resume	Allows interruption of sector erase to service real-time read/write requests in other sectors - essential for OTA firmware update without system freeze
Secured Silicon Sector	128-word (256-byte) factory- or customer-lockable region storing immutable electronic serial number - enables secure device authentication and anti-cloning
Unlock Bypass Program Mode	Reduces multi-byte programming overhead from 4 to 2 write cycles per byte - cuts flash update time by ~50% in sequential firmware patching
CFI Compliance	Standardized JEDEC register map enabling automatic host detection of geometry, timing, and command set - eliminates hardcoded driver dependencies across Flash vendors
Automatic Sleep Mode	Enters 0.2 µA sleep state after address stability timeout - reduces leakage in parked-vehicle monitoring circuits

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
S29AL008J70TFIR20	70 ns access time; same density, voltage, package, and feature set	Lower performance grade; suitable where microcontroller clock < 14 MHz or wait states acceptable	Select when cost sensitivity outweighs timing margin needs in non-safety-critical subsystems
MX29LV008CTTI-70G	70 ns access; 3.3 V only (no 2.7 V min); lacks CFI support and Secured Silicon Sector	No factory-locked serial ID; no standardized host auto-detection; reduced security for device identity	Choose only for legacy designs requiring pin compatibility with older Macronix platforms, not new AEC-Q100 designs

Compared with S29AL008J70TFIR20 and MX29LV008CTTI-70G, the S29AL008J55BFIR10 delivers tighter timing for high-speed microcontrollers, guaranteed low-voltage operation down to 2.7 V for brownout resilience, and integrated security features essential for modern automotive and medical certification.

FAQ

What boot sector configuration does S29AL008J55BFIR10 support?

The S29AL008J55BFIR10 supports both top-boot and bottom-boot configurations, selectable via hardware strapping or command sequence. In top-boot mode, the highest 16 KB sector (addresses 0xFF0000–0xFFFFFF) is protected by WP#; in bottom-boot mode, the lowest 16 KB sector (0x000000–0x003FFF) is protected. This flexibility enables compatibility with diverse bootloader architectures across automotive and industrial platforms.

Does S29AL008J55BFIR10 require external high-voltage programming?

No. The S29AL008J55BFIR10 operates exclusively from a single 2.7–3.6 V supply - no 12 V VPP or 5 V auxiliary voltage is needed for program or erase operations. Internal charge pumps generate all required high voltages, enabling in-system programming using only the host microcontroller's standard 3.0 V I/O interface and timing.

How is the Secured Silicon Sector programmed and locked?

The Secured Silicon Sector (128 words / 256 bytes) is programmed using a dedicated command sequence that writes to addresses 0x0000–0x007F within the secured region. Locking is performed via a separate lock command; once locked, the sector becomes permanently read-only. Factory programming and locking are available through Infineon's wafer-level customization services, ensuring unique, unalterable device identity before shipment.

Can S29AL008J55BFIR10 be used in place of older S29AL008D devices?

Yes - the S29AL008J55BFIR10 is fully backward-compatible with the S29AL008D in pinout, command set, and software interface. It is manufactured on a more advanced 110 nm process but maintains identical timing, voltage, and functional behavior, making it a direct drop-in replacement with improved power efficiency and extended temperature range support.
