Infineon Technologies S29JL032J60TFI023

Overview

S29JL032J60TFI023 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 hardware sector protection. It enables zero-latency background erase/program while reading from another bank-used in industrial HMI firmware storage where real-time UI responsiveness must coexist with field-upgradable code.

For engineers reviewing the S29JL032J60TFI023 datasheet, S29JL032J60TFI023 pinout, S29JL032J60TFI023 application, or S29JL032J60TFI023 equivalent, key selection criteria include simultaneous bank operation support, secured silicon region (256-byte OTP), JEDEC CFI compliance, boot sector configuration flexibility, and FBGA/TSOP package compatibility for legacy PCB reuse.

Technical Context

The S29JL032J60TFI023 implements a true dual-bank (or quad-bank) flash architecture with independent address decoders per bank, enabling concurrent read from one bank and program/erase in another. Its RY/BY# pin and DQ7/DQ6 status signaling provide deterministic hardware- and software-based operation completion detection.

It supports byte/word mode via BYTE# pin, uses autoselect command sequences for device identification, and integrates a low-VCC detector to inhibit writes during power transitions. The Secured Silicon Region is factory-programmable for electronic serial number and customer-lockable for one-time code storage.

FAQ

What package types are supported by S29JL032J60TFI023?

The S29JL032J60TFI023 is offered exclusively in the 48-ball Fine-pitch BGA (VBK048) package with 6 mm × 8 mm body and 0.8 mm ball pitch. It is not available in TSOP or other variants-the "60TFI023" suffix confirms this specific FBGA configuration per Infineon's ordering guide.

Does S29JL032J60TFI023 support true simultaneous read and write across all banks?

No-it supports simultaneous operation across only two banks at a time, even in the four-bank configuration. The architecture permits one bank to execute erase/program while another performs read; additional banks remain idle during that cycle. This is explicitly defined in Section 1 and Table 2 of the datasheet.

How is the Secured Silicon Region accessed and locked?

The 256-byte Secured Silicon Region is accessed using the Enter/Exit Secured Silicon Region command sequence (addresses 0x555/0x2AA). Locking is performed via a one-time program command; once locked, the DQ6 bit reads "1", and no further writes are possible-even with RESET# assertion or power cycling.

Can S29JL032J60TFI023 be used in byte-mode only systems?

Yes-BYTE# pin controls mode selection: high = byte mode (DQ7–DQ0 active, A0–A20 address range maps to 4M bytes); low = word mode (DQ15–DQ0 active, A0–A20 maps to 2M words). Both modes are fully supported and retain identical timing, protection, and status reporting behavior.
