Product details

Overview

S29AL008J70BFM023_791479U from Cypress Semiconductor is an 8-Mbit (1 M × 8-bit / 512 K × 16-bit) single-supply 3.0 V boot sector Flash memory with 55 ns access time, AEC-Q100 Grade 1 qualification (–40°C to +125°C), and 48-ball fine-pitch BGA (0.8 mm pitch) packaging. It supports in-system programming via standard 3.0 V VCC only-no 5 V or 12 V required-and features flexible sector architecture including one 16 KB, two 8 KB, one 32 KB, and fifteen 64 KB sectors for embedded firmware storage in automotive ECUs.

For engineers reviewing the S29AL008J70BFM023_791479U datasheet, S29AL008J70BFM023_791479U pinout, S29AL008J70BFM023_791479U application, or S29AL008J70BFM023_791479U equivalent, key selection criteria include boot-block configuration (top/bottom), sector protection granularity, CFI compliance for host auto-configuration, and hardware reset (RESET#) and ready/busy (RY/BY#) signaling for real-time operation monitoring.

Technical Context

The S29AL008J70BFM023_791479U implements a JEDEC-standard command-set architecture with embedded program/erase algorithms that internally manage pulse timing and margin verification. Its state-machine-driven control logic accepts standard microprocessor write timings to execute commands including sector erase, chip erase, unlock bypass programming, and erase suspend/resume.

It integrates hardware-level data protection via VCC detector, WP#-controlled boot-sector lock, and RESET#-initiated state recovery. The device supports dual data width modes (x8/x16) via BYTE# pin, with DQ15/A-1 serving as either MSB data or LSB address depending on mode, enabling compatibility across 8-bit and 16-bit bus systems without external glue logic.

Key Specifications

Pinout & Package

Package: 48-ball fine-pitch BGA (VBK048), 8.15 mm × 6.15 mm × 1.00 mm, 0.8 mm ball pitch, RoHS-compliant.

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 bidirectional data lines; DQ15/A-1 serves as 16th data bit or LSB address depending on BYTE# state.
CE#, OE#, WE#	Chip/Output/Write Enable	Independent controls eliminate bus contention; allows interleaved read/write in multi-device systems.
RY/BY#	Ready/Busy output	Active-low open-drain signal indicating active program/erase cycle - enables hardware polling without CPU overhead.
RESET#	Hardware reset input	Asynchronous reset of internal state machine to read mode - synchronizes boot sequence with MCU reset assertion.
WP#	Write protect input	Hardware lock for top/bottom 16 KB boot sector; internal pull-up allows default VIH when unconnected.
BYTE#	Data width select	Configures x8 (BYTE# = VIH) or x16 (BYTE# = VIL) operation - eliminates need for external multiplexing logic.

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory- or customer-programmable region with 8-word electronic serial number - enables secure device identity binding for OTA authentication.
Erase Suspend/Resume	Allows interruption of sector erase to read/program non-target sectors - enables true background firmware update without halting real-time control tasks.
Unlock Bypass Programming	Reduces multi-byte programming sequences from four to two write cycles - cuts flash update time by ~50% in bootloader implementations.
CFI Compliance	Standardized query table accessible via command sequence - permits generic host drivers to auto-detect geometry, voltage, and timing parameters without hard-coded assumptions.
Automatic Sleep Mode	Enters 0.2 µA sleep after address stability timeout - eliminates need for explicit power-down commands in low-duty-cycle sensor nodes.

FAQ

What boot configuration options does the S29AL008J70BFM023_791479U support?

The device supports both top-boot and bottom-boot configurations, determined by the WP# pin state during power-up. When WP# is held low, the first 16 KB sector (addresses 0x000000–0x003FFF) is protected; when high, the last 16 KB sector (0xFFC000–0xFFFFFF) is protected. This flexibility allows alignment with bootloader placement requirements in diverse MCU architectures.

How does the Secured Silicon Sector differ from standard Flash sectors?

The Secured Silicon Sector is a dedicated 256-byte region with factory- or customer-programmable 16-byte electronic serial number and permanent lock capability. Unlike regular sectors, it cannot be erased via standard commands once locked, and its contents are readable only through a specific command sequence-providing tamper-resistant device identification for secure boot and licensing.

Can the S29AL008J70BFM023_791479U operate reliably at 2.7 V during program operations?

Yes-the device is fully specified for program and erase operations across the entire 2.7 V to 3.6 V range. Internal charge pumps generate required programming voltages regardless of VCC level, ensuring consistent 1,000,000-cycle endurance and 20-year data retention even at minimum supply voltage, critical for battery-powered automotive subsystems.

Is the 48-ball BGA package (VBK048) compatible with standard reflow profiles?

Yes-the VBK048 package is qualified for lead-free reflow per IPC/JEDEC J-STD-020 Rev. E, with peak temperature up to 260°C. Cypress specifies a maximum board-side temperature of 150°C during ultrasonic cleaning or post-assembly handling to prevent package delamination or solder joint damage.
