Infineon Technologies S29JL032J60BHI313

Overview

S29JL032J60BHI313 from Infineon Technologies (formerly Cypress) is a 32-Mb simultaneous read/write flash memory organized as 4M × 8-bit or 2M × 16-bit, operating at 3.0 V only, with 60 ns access time, four-bank architecture, and boot-sector configuration. It enables zero-latency background erase/program in one bank while reading from another-critical for real-time firmware updates in industrial controllers.

For engineers reviewing the S29JL032J60BHI313 datasheet, S29JL032J60BHI313 pinout, S29JL032J60BHI313 application, or S29JL032J60BHI313 equivalent, key selection criteria include simultaneous bank operation support, secured silicon region (256-byte OTP), JEDEC CFI compliance, hardware sector protection, and FBGA-48 package compatibility with legacy TSOP-48 footprints.

Technical Context

The S29JL032J60BHI313 implements a true 4-bank flash architecture where each bank operates independently under shared control logic; banks are fixed in address space and support concurrent read and program/erase operations with no arbitration delay. Its command interface fully complies with JEDEC 42.4 single-power-supply Flash standards, using standard microprocessor write timings for command register loading.

Hardware features include RY/BY# status signaling, RESET# for state machine recovery, WP#/ACC for boot-sector write protection and accelerated programming, and BYTE# for 8-/16-bit mode selection. The Secured Silicon Region provides factory-locked 16-byte ESN plus customer-lockable 256-byte OTP space verifiable via autoselect.

FAQ

What is the function of the WP#/ACC pin on S29JL032J60BHI313?

The WP#/ACC pin serves two distinct hardware functions: when held low, it permanently protects the two outermost boot sectors from program/erase operations; when pulsed low during programming, it activates accelerated programming mode, reducing word-program time to 6 µs typical. This dual role eliminates need for external logic to manage boot security and performance tuning.

Does S29JL032J60BHI313 support true background erase across all banks?

No-only two banks can operate simultaneously: one for read, one for erase/program. The device's four-bank architecture allows flexible grouping, but hardware limits concurrent active operations to two banks. Background erase is achieved by suspending the erase in one bank to service read requests in another, then resuming-enabled by Erase Suspend/Erase Resume commands.

How is the Secured Silicon Region accessed and locked?

The Secured Silicon Region (256-byte OTP sector) is accessed using dedicated Enter/Exit Secured Silicon Region command sequences. Factory locking sets DQ6=1 and provides a 16-byte ESN; customer locking is one-time programmable via specific unlock-bypass-write sequence. Once locked, no further writes are possible-even with valid unlock commands-and the lock status is verifiable through autoselect mode.

Can S29JL032J60BHI313 be used in 8-bit microcontroller systems?

Yes-via BYTE# pin assertion (low), the device operates in 8-bit mode with data on DQ7–DQ0, maintaining full command compatibility and sector protection functionality. Address lines A0–A20 remain fully utilized, and all timing specifications-including 60 ns access-apply identically in both 8-bit and 16-bit configurations.
