Product details
Overview
S29JL064J55TFI000 from Infineon Technologies (formerly Cypress) is a 64-Mb simultaneous read/write flash memory IC, organized as 4M × 16-bit or 8M × 8-bit, operating at 3.0 V only with 55 ns access time. It features four-bank architecture enabling zero-latency concurrent read and program/erase operations, secured silicon region with factory-locked 16-byte ESN, and JEDEC-compliant CFI interface. Used in embedded boot code storage for industrial controllers requiring nonvolatile firmware persistence and in-system reprogramming.
For engineers reviewing the S29JL064J55TFI000 datasheet, S29JL064J55TFI000 pinout, S29JL064J55TFI000 application, or S29JL064J55TFI000 equivalent, key selection criteria include simultaneous bank operation capability, 256-byte secured silicon sector lockability, 55 ns tACC timing, hardware write protection via WP#/ACC, and FBGA/TSOP package compatibility with legacy board layouts.
Technical Context
The device implements a four-bank flash architecture-two 8 Mb banks (with mixed 8 KB/64 KB sectors) and two 24 Mb banks (all 64 KB sectors)-enabling true background erase and program while reading from any non-busy bank. Bank grouping is software-configurable, and sector erase is fully independent per sector.
It supports Common Flash Interface (CFI) for automatic device identification, erase suspend/resume for interruptible operations, and dual-mode data bus (DQ15/A−1 pin enables byte/word mode selection). Status reporting uses RY/BY# pin, DQ7 data polling, and DQ6/DQ2 toggle bits-no external status register required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mb (4,194,304 × 16-bit or 8,388,608 × 8-bit), sufficient for full bootloader + application firmware in space-constrained designs |
| Access Time (tACC) | 55 ns max - enables direct execution from flash (XIP) in real-time microcontroller systems without wait states |
| Operating Voltage | 2.7–3.6 V single supply - eliminates need for separate VPP programming voltage or level shifters |
| Program Time | 7 µs/word typical with acceleration - reduces firmware update duration in field-deployed devices |
| Endurance & Retention | 1 million erase/program cycles per sector; 20-year data retention - meets industrial lifecycle requirements |
| Power Consumption | 2 mA active read @ 1 MHz; 200 nA standby - suitable for battery-backed or energy-harvesting systems |
| Secured Silicon Region | 256-byte one-time programmable sector with factory-locked 16-byte ESN - provides hardware root-of-trust for secure boot |
Pinout & Package
Available in 48-ball fine-pitch BGA (VBK048) and 48-pin TSOP (TS 048) packages. Both are RoHS-compliant, lead-free, and support standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A21–A0 | Address Inputs | 22-bit address bus supporting full 4M-word addressing in x16 mode; A−1 alias on DQ15 enables LSB address in x8 mode |
| DQ15–DQ0 | Data I/O (x16) | 16-bit bidirectional data bus; DQ15 doubles as A−1 in byte mode for seamless 8/16-bit configuration |
| CE#, OE#, WE# | Control Enables | Standard asynchronous control signals - eliminate bus contention and support glueless interfacing with MCU parallel buses |
| WP#/ACC | Hardware Write Protect / Acceleration | Active-low pin that permanently disables writes to boot sectors 0/1/140/141; when driven high during programming, enables accelerated 7 µs/word timing |
| RY/BY# | Ready/Busy Output | Open-drain active-low signal indicating internal operation completion - allows polling-free interrupt-driven firmware updates |
| RESET# | Hardware Reset | Asynchronous active-low input forcing device into read mode - critical for recovery after power brownout or watchdog timeout |
| BYTE# | Bus Width Select | Active-low input selecting 8-bit (DQ7–DQ0) or 16-bit (DQ15–DQ0) data transfer - enables flexible MCU interface without redesign |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous Read/Write | Zero-latency concurrent access across four independent banks - eliminates CPU idle time during firmware updates |
| Flexible Bank Architecture | Software-definable bank groupings (e.g., 2×32 Mb or 4×16 Mb) - adapts to varying boot/application partitioning needs |
| Boot Sector Protection | Top and bottom boot sectors with hardware write protection - prevents accidental overwrite of critical startup code |
| Secured Silicon Region | Factory-locked 256-byte sector containing verifiable 16-byte ESN - enables cryptographic key binding and anti-cloning |
| Erase Suspend/Resume | Pause ongoing sector erase to read/program another sector - supports real-time data logging during background firmware upgrade |

FAQ
What is the function of the WP#/ACC pin?
The WP#/ACC pin serves dual roles: when held low, it hardware-protects boot sectors 0, 1, 140, and 141 from accidental erase or program; when driven high during programming, it activates accelerated timing (7 µs/word). This eliminates need for external logic to manage sector protection or optimize write speed.
How does the Secured Silicon Region support secure boot?
The Secured Silicon Region contains a factory-locked 16-byte Electronic Serial Number (ESN) verified via autoselect command. Its DQ6 indicator bit distinguishes factory-locked (DQ6 = 0) from customer-locked (DQ6 = 1) parts, preventing substitution and enabling cryptographic binding of firmware images to specific hardware units.
Can the S29JL064J55TFI000 operate in both 8-bit and 16-bit modes?
Yes - the BYTE# pin selects bus width: low enables 16-bit mode (DQ15–DQ0), high enables 8-bit mode (DQ7–DQ0), with DQ15 repurposed as A−1 address input. This allows reuse of the same PCB footprint across different MCU data bus widths without redesign.
What is the practical benefit of erase suspend/resume functionality?
Erase suspend/resume allows pausing an ongoing sector erase to read or program another sector, then resuming the original erase. In practice, this enables real-time data logging or UI updates during background firmware upgrades - eliminating system freezes and ensuring uninterrupted operation in safety-critical applications.
