Product details

Overview

S29AL008J70BFI020 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, 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 V_CC, features Secured Silicon Sector with 128-word ESN, and enables automotive firmware storage with hardware write protection and erase suspend/resume.

For engineers reviewing the S29AL008J70BFI020 datasheet, S29AL008J70BFI020 pinout, S29AL008J70BFI020 application, or S29AL008J70BFI020 equivalent, key selection criteria include boot-block configuration (top/bottom), sector protection granularity (16 KB to 64 KB), CFI compliance for host auto-configuration, and RY/BY# / DQ7 polling for operation status monitoring in real-time embedded systems.

Technical Context

The S29AL008J70BFI020 implements a JEDEC-compliant single-power-supply Flash command set with embedded algorithms for program (hot electron injection) and erase (Fowler-Nordheim tunneling). Its flexible sector architecture includes one 16 KB, two 8 KB, one 32 KB, and fifteen 64 KB sectors in byte mode - enabling selective firmware updates without full chip erasure.

Hardware features include dedicated RY/BY# for cycle completion signaling, RESET# for state-machine reset during power-on or error recovery, and WP# that protects the boot sector (first or last 16 KB) depending on configuration. The device supports both x8 and x16 data bus modes via DQ15/A-1 and BYTE# control, with automatic sleep and standby modes reducing current to 0.2 µA.

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 (x8/x16)	Bi-directional data bus; DQ15/A-1 serves as LSB address in byte mode or MSB data in word mode
DQ15/A-1	Multi-function terminal	Enables dual-mode interface: data bit 15 (x16) or address bit –1 (A-1) for byte-mode alignment
CE#, OE#, WE#	Chip/Output/Write enable	Independent controls eliminate bus contention; support asynchronous read/write timing
RY/BY#	Ready/Busy output	Active-low open-drain signal indicating active program/erase - used for hardware flow control
RESET#	Hardware reset input	Forces device into read-array state; synchronizes boot sequence with system MCU reset
WP#	Write protect input	Locks boot sector (16 KB) when pulled low - prevents accidental overwrite of critical startup code
BYTE#	Bus width select	Configures x8 (BYTE# = VIH) or x16 (BYTE# = VIL) data interface - no external glue logic required

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory- or customer-programmable region with 8-word ESN for secure device identification
Erase Suspend/Resume	Allows background erase to pause while reading/programming non-target sectors - enables real-time firmware patching
Unlock Bypass Mode	Reduces multi-byte programming time by cutting command sequence from 4 to 2 write cycles per data word
CFI Compliance	Provides standardized register map for host software to auto-detect geometry, timing, and command set - simplifies BSP porting
Hardware Sector Protection	Individual sector lock via WP# or command sequence - prevents corruption during power brownout or firmware crash

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, TSOP-48 package (18.4 mm × 12.0 mm) instead of BGA; identical timing and command set	Preferred for through-hole prototyping or legacy PCBs with TSOP footprints; lacks BGA's board space efficiency	Select when mechanical compatibility with existing TSOP layouts is required and thermal profile permits larger footprint
MX29LV008CTTI-70G	8 Mbit, 3 V Flash with 70 ns access; no Secured Silicon Sector; different CFI implementation and command timing	Lacks ESN and factory-lock capability; not AEC-Q100 qualified; limited to industrial temp range (–40 °C to +85 °C)	Acceptable for cost-sensitive industrial applications where secure identification and automotive qualification are not required

Compared with S29AL008J70TFI020, the BGA variant offers superior thermal dissipation and board density for space-constrained automotive modules; versus MX29LV008CTTI-70G, it delivers verified security features, extended temperature operation, and guaranteed erase endurance - critical for safety-critical firmware storage.

FAQ

What boot sector configuration does S29AL008J70BFI020 support?

The S29AL008J70BFI020 supports both top-boot and bottom-boot configurations, selectable via hardware strapping or command sequence. In top-boot mode, the first 16 KB sector (addresses 0x000000–0x003FFF) is protected; in bottom-boot mode, the last 16 KB sector (0xFFC000–0xFFFFFF) is protected. WP# pin state determines default behavior at power-up.

How is the Secured Silicon Sector programmed and locked?

The Secured Silicon Sector (128 words / 256 bytes) is programmed using the standard Word Program command sequence after entering the Secured Silicon Sector mode. Locking is performed via the Sector Protect command; once locked, the sector becomes read-only until next power cycle unless unlocked via specific command. Factory locking is available upon order specification.

Does S29AL008J70BFI020 require external high-voltage circuitry for programming?

No. The S29AL008J70BFI020 operates with a single 3.0 V supply (2.7–3.6 V) for all read, program, and erase operations. Internal charge pumps generate required high voltages for Fowler-Nordheim tunneling and hot electron injection - eliminating need for external VPP or 5 V rails.

What is the function of the BYTE# pin in x8 vs. x16 mode?

When BYTE# = VIH, the device operates in x8 mode: DQ0–DQ7 carry data, and DQ15/A-1 functions as A-1 (LSB address). When BYTE# = VIL, it operates in x16 mode: DQ0–DQ15 carry data, and A-1 is unused. This pin enables seamless interface to 8-bit or 16-bit microcontrollers without external multiplexing.
