Product details
Overview
S29JL032J70TFI423 from Infineon Technologies (formerly Cypress) is a 32-Mb, 3.0 V-only simultaneous read/write flash memory organized as 4M × 8-bit or 2M × 16-bit. It features zero-latency bank interleaving, 70 ns access time, 4-bank architecture, secured silicon region (256 B), and JEDEC CFI compliance. Used in industrial control firmware storage where concurrent code execution and background update are required.
For engineers reviewing the S29JL032J70TFI423 datasheet, S29JL032J70TFI423 pinout, S29JL032J70TFI423 application, or S29JL032J70TFI423 equivalent, key selection criteria include simultaneous read/write latency, boot sector configuration flexibility, hardware write protection (WP#/ACC), RY/BY# status signaling, and FBGA/TSOP package compatibility with legacy PCB footprints.
Technical Context
The S29JL032J70TFI423 implements a 4-bank flash architecture enabling true concurrent operations: one bank executes erase or program while another serves active read requests without pipeline stall. Each bank supports independent sector erase and byte/word programming via standard JEDEC command set.
It integrates hardware-level data integrity features including automatic sleep mode (200 nA), low-VCC write inhibition, erase suspend/resume, and toggle-bit (DQ6/DQ2) + polling (DQ7) status reporting. The Secured Silicon Region provides factory-locked 16-byte ESN and customer-one-time-programmable 256-byte space.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mb (4,194,304 × 8-bit or 2,097,152 × 16-bit); enables full firmware image storage for mid-tier microcontrollers. |
| Access Time | 70 ns max (tACC); meets real-time interrupt response timing in industrial PLCs and motor drives. |
| Banks | 4 independent banks; allows background firmware update while executing application code from alternate bank. |
| Power Modes | 200 nA standby/automatic sleep; reduces system quiescent current in battery-backed or energy-constrained edge nodes. |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over 10+ years in deployed equipment. |
| Data Retention | 20 years typical at 125°C; qualified for automotive under-hood and industrial high-temp environments. |
| Interface Standard | JEDEC 42.4 CFI-compliant; ensures bootloader compatibility across toolchains and flash programmers. |
Pinout & Package
Package: 48-ball Fine-pitch BGA (VBK048 footprint). Ball pitch: 0.8 mm. Body size: 8.0 mm × 10.0 mm × 1.2 mm. RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus supporting full 4M×8 or 2M×16 addressing; A-1 used only in word mode for DQ15/A-1 multiplexing. |
| DQ0–DQ15 | Data I/O (16-bit) | Bidirectional data bus; operates in byte (DQ0–DQ7) or word (DQ0–DQ15) mode controlled by BYTE#. |
| CE#, OE#, WE# | Chip/Output/Write Enable | Standard asynchronous control signals; enable bus contention avoidance and multi-device memory mapping. |
| RY/BY# | Ready/Busy Output | Active-low open-drain status signal indicating completion of program/erase; eliminates need for software polling loops. |
| RESET# | Hardware Reset Input | Asynchronous reset to read mode; critical for recovery after power brownout or watchdog timeout events. |
| WP#/ACC | Write Protect / Acceleration | Dual-function pin: WP# protects boot sectors unconditionally; ACC enables 6 µs/word accelerated programming. |
| BYTE# | Byte/Word Mode Select | Configures data bus width; determines whether DQ0–DQ7 (byte) or DQ0–DQ15 (word) are active during transfers. |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous Read/Write | Zero-latency bank interleaving enables real-time firmware update without halting application execution. |
| Secured Silicon Region | 256-byte OTP sector with factory-locked 16-byte ESN; provides tamper-resistant device identity and secure boot key storage. |
| Erase Suspend/Resume | Pause ongoing sector erase to service urgent read/write requests elsewhere; enables deterministic latency in safety-critical systems. |
| Hardware Write Protection | WP# pin permanently disables programming/erasing of top/bottom boot sectors regardless of software lock state. |
| Automatic Sleep Mode | Enters ultra-low-power state (200 nA) after address stability timeout; eliminates external power management IC in portable designs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N70TFI010 | 45 nm process, 70 ns access, same 4-bank architecture but lacks Secured Silicon Region and erase suspend. | Lower cost for non-secure, non-concurrent-update use cases; not suitable for OTA-capable devices. | Select when security and background erase are unnecessary and bill-of-materials cost is primary. |
| MX29GL320EBTI-70G | 32 Mb, 70 ns, 3 V, but uses 2-bank architecture and lacks WP#/ACC dual-function pin. | Requires external logic for boot sector protection; no hardware-accelerated programming. | Choose only if existing design uses MXIC's command set and does not require simultaneous bank operations. |
Compared with S29GL032N70TFI010 and MX29GL320EBTI-70G, the S29JL032J70TFI423 uniquely delivers zero-latency concurrent access, factory-locked ESN, and integrated WP#/ACC functionality-making it the only option for secure, real-time firmware update in industrial and automotive edge nodes.

FAQ
What is the difference between S29JL032J70TFI423 and S29JL032J60TFI423?
The S29JL032J70TFI423 has a maximum access time of 70 ns, while the S29JL032J60TFI423 guarantees 60 ns. Both share identical pinout, command set, and feature set. The 70 ns variant targets cost-sensitive applications where slightly relaxed timing margins are acceptable, such as non-real-time industrial HMIs or legacy controller upgrades.
Does S29JL032J70TFI423 support both 8-bit and 16-bit data bus configurations?
Yes. The device supports byte mode (DQ0–DQ7) and word mode (DQ0–DQ15) via the BYTE# pin. In word mode, A-1 appears on DQ15 during address latching. This dual-width capability allows seamless integration with 8-bit microcontrollers (e.g., legacy 8051-based systems) and 16-bit processors (e.g., TI C2000 DSPs) without redesigning the memory interface.
How is the Secured Silicon Region programmed and locked?
The Secured Silicon Region is accessed using the Enter Secured Silicon Region command sequence (0x555=0xAA, 0x2AA=0x55, 0x555=0xB0). Data is written like any flash sector. Locking is performed with the Secured Silicon Region Lock command (0x555=0xAA, 0x2AA=0x55, 0x555=0xB8), which permanently sets the DQ6 indicator bit and disables further writes. Once locked, the region is read-only and factory-verifiable.
Can S29JL032J70TFI423 operate reliably at 2.7 V?
Yes. The device is specified for VCC = 2.7–3.6 V in the 70 ns speed grade. At 2.7 V, all AC and DC parameters-including 70 ns access time, 100K erase cycles, and 200 nA standby current-remain fully guaranteed per datasheet Section 13 (Operating Ranges) and Section 14 (DC Characteristics). This enables direct replacement in brownout-prone battery-powered systems.
