Product details

Overview

S29AL008J70BFI023 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 qualification (–40°C to +125°C), and 48-ball fine-pitch BGA (VBK048) packaging. It supports in-system programming via standard 3.0 V V_CC, includes hardware write protection (WP#), Ready/Busy# signaling, and Secured Silicon Sector with factory-programmable 128-word electronic serial number - deployed in automotive engine control units for firmware storage and update.

For engineers reviewing the S29AL008J70BFI023 datasheet, S29AL008J70BFI023 pinout, S29AL008J70BFI023 application, or S29AL008J70BFI023 equivalent, key selection criteria include boot-sector architecture (top/bottom configurable), CFI compliance for host auto-configuration, erase suspend/resume capability, 1M-cycle endurance per sector, and 20-year data retention under automotive thermal stress.

Technical Context

The S29AL008J70BFI023 implements a JEDEC-compliant single-power-supply Flash command set with embedded algorithms for program and erase operations. Its internal state machine latches addresses/data during writes and verifies cell margin post-program/erase using Data# Polling (DQ7) and Toggle Bits (DQ6/DQ2).

It features dual-mode bus interface: byte mode (DQ7–DQ0 active, DQ15/A−1 as LSB address) and word mode (DQ15–DQ0 active). Sector architecture comprises one 16 KB, two 8 KB, one 32 KB, and fifteen 64 KB sectors - enabling selective reprogramming without disturbing firmware in protected boot blocks.

Pin/Terminal	Circuit Role	Design Meaning
A0–A18	Address Inputs	19-bit address bus supporting full 1 Mbyte/512 Kword addressing; A18 selects top/bottom boot configuration
DQ0–DQ14	Data I/O (x16 mode)	15-bit bidirectional data path; DQ15/A−1 serves as MSB data (x16) or LSB address (x8)
DQ15/A−1	Data/Address Multiplex	Configures bus width: DQ15 active in x16 mode; A−1 used as LSB in x8 mode for byte alignment
CE#, OE#, WE#	Chip/Output/Write Enable	Independent controls eliminate bus contention; CE# gating reduces standby current to 0.2 µA
WP#, RESET#, RY/BY#	Hardware Protection & Status	WP# locks boot sector at V_IL; RESET# forces read mode on power-up; RY/BY# provides cycle completion signal

Key Features

Feature	Design Value

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, 48-pin TSOP package (TS048), 70 ns access time, no BGA thermal pad	Preferred for through-hole prototyping or legacy board redesigns where BGA rework is prohibitive	Select when manual soldering, thermal testing, or socket-based validation is required
MX29LV008CTTI-70G	Macronix part, 8 Mbit, 70 ns, 3 V, TSOP-48, but lacks CFI support and Secured Silicon Sector	Used in cost-sensitive industrial HMIs where firmware security and auto-configuration are not required	Choose only if CFI and electronic serial number features are excluded from system design

Compared with S29AL008J70TFI020, the BGA variant offers superior thermal dissipation and board density; versus MX29LV008CTTI-70G, it delivers certified automotive reliability, secure identity, and host-software portability via CFI - making it the sole option for safety-critical AEC-Q100 deployments.

FAQ

Is S29AL008J70BFI023 pin-compatible with earlier S29AL008D variants?

Yes - the S29AL008J70BFI023 maintains identical pinout and command set compatibility with the S29AL008D family, including TSOP and BGA packages. The 110 nm process improves power efficiency and thermal performance while preserving mechanical and electrical interoperability for drop-in replacement in existing designs.

What boot configuration options does S29AL008J70BFI023 support?

The device supports both top-boot and bottom-boot configurations determined by A18 address line state at power-up. In top-boot mode, the highest 16 KB sector (addresses 0xFF000–0xFFFFF) is protected; in bottom-boot mode, the lowest 16 KB sector (0x00000–0x03FFF) is protected - selectable via hardware strap or firmware initialization.

How does the Secured Silicon Sector function in practice?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed with a unique 8-word electronic serial number. Once locked via command sequence, it becomes permanently read-only. Customers may program and lock it during production or leave it unlocked for field provisioning - accessed only via defined CFI query commands.

Does S29AL008J70BFI023 require external high-voltage circuitry for programming?

No - the device uses internally generated and regulated voltages for all program and erase operations. Only a single 3.0 V supply (2.7–3.6 V range) is required; no 5 V V_CC or 12 V V_PP is needed. This simplifies power design and eliminates external charge pumps or voltage translators in embedded systems.
