Product details
Overview
S29JL032J60TFI423 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 while reading from another bank, supporting embedded firmware storage in industrial controllers and network edge devices.
For engineers reviewing the S29JL032J60TFI423 datasheet, S29JL032J60TFI423 pinout, S29JL032J60TFI423 application, or S29JL032J60TFI423 equivalent, key selection criteria include simultaneous bank operation support, secured silicon region (256-byte OTP), JEDEC CFI compliance, hardware write protection via WP#/ACC, and FBGA/TSOP package compatibility for space-constrained PCB layouts.
Technical Context
The S29JL032J60TFI423 implements a true four-bank flash architecture where two banks operate concurrently-one for read, one for erase or program-enabling real-time firmware updates without halting host execution. Each bank supports independent sector erase and byte/word programming under common 3.0 V supply.
It integrates JEDEC-standard Common Flash Interface (CFI) for automatic device identification, supports erase suspend/resume for interruptible background operations, and includes dual status detection: RY/BY# pin and DQ7/DQ6/DQ2 polling/toggle bits for precise cycle completion monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mb (4M × 8-bit / 2M × 16-bit); enables full bootloader + application image storage in single device |
| Access Time | 60 ns (tACC); meets timing requirements for 16-bit microcontroller interfaces running ≤16 MHz |
| Banks | Four independent banks; allows concurrent read from one bank while erasing/programming another |
| Power Supply | 3.0 V only (2.7–3.6 V range); eliminates need for dual-voltage rails in modern low-power systems |
| Standby Current | 200 nA; enables ultra-low-power retention in battery-backed or energy-harvesting applications |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over 10+ years of industrial deployment |

Pinout & Package
Package: 48-ball Fine-pitch BGA (VBK048 footprint). Pinout validated per Infineon Document 002-00857 Rev. *J, Figure 4.2 and Table 5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus supporting full 4M-byte or 2M-word addressing; BYTE# selects 8-/16-bit mode |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; DQ7–DQ0 used in byte mode, DQ15–DQ0 in word mode |
| CE#, OE#, WE# | Chip/Output/Write Enable | Standard JEDEC control signals; prevent bus contention and define read/write timing windows |
| RY/BY# | Ready/Busy Output | Active-low hardware status signal indicating active program/erase; enables deterministic interrupt-driven polling |
| WP#/ACC | Write Protect / Acceleration | Hardware lock for top/bottom boot sectors; ACC mode reduces program time to 6 µs/word |
| RESET# | Hardware Reset | Asynchronous reset of internal state machine to read mode; required for recovery after power-up or error |
| BYTE# | Bus Width Select | Configures interface as 8-bit (BYTE# = LOW) or 16-bit (BYTE# = HIGH); no external glue logic needed |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous Read/Write | Zero-latency interleaving across four banks enables real-time firmware patching without CPU stall |
| Secured Silicon Region | 256-byte OTP sector with factory-locked ESN and customer-lockable code storage for secure boot keys |
| Erase Suspend/Resume | Pause background erase to service urgent read/write requests in unprotected sectors, then resume |
| Zero-Power Operation | Automatic sleep mode draws only 200 nA when addresses stable >100 µs, critical for always-on IoT nodes |
| Hardware Sector Protection | Independent lock/unlock of any sector group via WP# or command sequence, preventing accidental corruption |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29JL032J70TFI423 | 70 ns access time; wider voltage range (2.7–3.6 V); same pinout and command set | Lower performance margin for high-speed microcontrollers; better suited for battery-powered or wide-temp industrial use | Select when system clock <12 MHz or operating temperature exceeds –40°C to +105°C |
| S29GL032N90TFI010 | 32 Mb MirrorBit NOR flash; 90 ns access; different command set (no CFI autoselect); 48-pin TSOP only | Lacks simultaneous read/write; no secured silicon region; requires software adaptation for legacy designs | Choose only for cost-sensitive, non-security-critical replacements where bank interleaving is unused |
Compared with S29JL032J70TFI423 and S29GL032N90TFI010, the S29JL032J60TFI423 uniquely delivers 60 ns speed with zero-latency bank concurrency and factory-programmed ESN-critical for secure, real-time embedded systems requiring both performance and trust anchors.

FAQ
What is the function of the WP#/ACC pin on the S29JL032J60TFI423?
The WP#/ACC pin serves dual functions: as WP# (active-low), it permanently protects the top and bottom boot sectors from accidental program/erase; as ACC (acceleration), it enables faster 6 µs/word programming when driven high during command sequences. This dual-mode pin eliminates need for external logic to manage protection and performance modes.
Does the S29JL032J60TFI423 support true background erase?
Yes-it supports true background erase via Erase Suspend/Erase Resume commands. While erasing one sector, the host can suspend the operation, read or program any non-erasing sector, then resume the original erase. This capability is enabled by its four-bank architecture and independent bank control logic, not just software polling.
How is the Secured Silicon Region accessed and locked?
The Secured Silicon Region (256-byte OTP sector) is accessed using the Enter/Exit Secured Silicon Region command sequence (0x80 → 0x90 → 0xF0). Factory locking sets DQ6=1 and provides a verifiable 16-byte ESN; customer locking is one-time programmable via standard program commands and permanently disables further writes to that sector.
Can the S29JL032J60TFI423 operate in both 8-bit and 16-bit bus configurations?
Yes-via the BYTE# pin: logic LOW configures DQ7–DQ0 as data bus for 8-bit microcontrollers; logic HIGH enables full DQ15–DQ0 for 16-bit interfaces. Address mapping remains consistent (A0–A20), and all command sequences function identically in both modes without software modification.
