Product details
Overview
S29JL064J70TFI003 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. It features zero-latency concurrent read/erase-program operations across four independent banks, 55–70 ns access time, and integrated Secured Silicon Region with factory-locked 16-byte ESN for secure boot in embedded control systems.
For engineers reviewing the S29JL064J70TFI003 datasheet, S29JL064J70TFI003 pinout, S29JL064J70TFI003 application, or S29JL064J70TFI003 equivalent, key selection criteria include bank-level concurrency support, JEDEC CFI compliance, hardware sector protection, RY/BY# status signaling, and FBGA/TSOP package compatibility for industrial firmware storage.
Technical Context
The device implements a four-bank 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. Sector erase suspend/resume and autoselect mode are fully supported via standard CFI command set.
It uses internal charge pumps to generate high-voltage programming/erasing conditions from a single 3.0 V supply, supports BYTE#-controlled x8/x16 data width, and integrates hardware write protection (WP#) plus acceleration (ACC) on a shared pin. Reset# and RY/BY# provide deterministic state recovery and cycle completion detection.
Key Specifications

|---|---|
| Memory Density | 64 Mb (4,194,304 × 16-bit or 8,388,608 × 8-bit) |
| Access Time (tACC) | 70 ns - defines maximum clock-to-data delay in high-speed read cycles |
| Program Time | 7 µs/word typical - enables rapid field firmware updates without host CPU blocking |
| Standby Current | 200 nA - ensures ultra-low power retention during system sleep states |
| Cycling Endurance | 1 million cycles/sector - supports long-term field reprogramming in industrial controllers |
| Data Retention | 20 years - guarantees firmware integrity over full product lifecycle |
| Supply Voltage | 2.7–3.6 V - single-rail operation compatible with 3.3 V logic domains |
Pinout & Package
Package: 48-ball Fine-pitch BGA (VBK048) and 48-pin TSOP (TS 048), both RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A21–A0 | Address Inputs | 22-bit address bus supporting full 64 Mb addressing in word or byte mode |
| DQ15–DQ0 | Data I/O (x16) | 16-bit bidirectional data path; DQ15/A-1 serves as LSB address in byte mode |
| CE#, OE#, WE# | Control Enables | Standard asynchronous flash control signals preventing bus contention |
| RY/BY# | Status Output | Active-low hardware flag indicating active program/erase cycle completion |
| RESET# | Hardware Reset | Forces device into read mode and clears internal state machine on power-up or fault recovery |
| WP#/ACC | Protection/Accel | Write-protects boot sectors (0,1,140,141); ACC mode reduces program timing overhead |
| BYTE# | Bus Width Select | Active-low input selecting 8-bit (BYTE# = L) or 16-bit (BYTE# = H) data interface |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous Read/Write | Zero-latency concurrent operation across four banks enables real-time firmware update without interrupting host execution |
| Secured Silicon Region | 256-byte one-time programmable sector with factory-locked 16-byte ESN for anti-cloning and secure boot authentication |
| Erase Suspend/Resume | Allows temporary interruption of sector erase to service urgent read/program requests elsewhere, enabling true background operation |
| Hardware Sector Protection | Independent locking of any sector combination via WP# or command sequence prevents accidental corruption of boot or configuration code |
| Automatic Sleep Mode | Enters <200 nA quiescent current after address stability timeout - eliminates need for external power gating in battery-powered edge devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S70TFI010 | 64 Mb, 3 V, 70 ns, MirrorBit® technology; lacks Secured Silicon Region and simultaneous read/write | No factory-locked ESN or background erase; requires full chip or sector erase before reprogramming | Select when security and zero-latency concurrency are not required, and cost optimization is prioritized |
| MX29GL640EHTI-70G | 64 Mb, 3 V, 70 ns, standard NOR flash; no bank concurrency, no secured silicon, CFI-compatible but no erase suspend | Single-bank architecture limits firmware update flexibility; no hardware-based boot sector protection | Choose for legacy designs where JEDEC CFI compliance suffices and background operation is handled externally |
Compared with S29JL064J70TFI003, the S29GL064S70TFI010 offers lower cost but sacrifices secure boot and real-time background programming, while MX29GL640EHTI-70G provides basic CFI compatibility without hardware concurrency or silicon-level security features essential for modern embedded firmware integrity.

FAQ
What is the purpose of the WP#/ACC pin on the S29JL064J70TFI003?
The WP#/ACC pin serves dual functions: as WP# (Write Protect), it permanently disables programming and erasure of boot sectors 0, 1, 140, and 141 regardless of software protection status; as ACC (Acceleration), it enables faster program timing by activating internal voltage boost circuitry during write sequences. Both modes are selected automatically based on command context and timing, not external logic level.
How does the Secured Silicon Region differ between factory-locked and customer-lockable versions?
Factory-locked Secured Silicon contains a verifiable 16-byte random Electronic Serial Number and is permanently read-only; its lock status is confirmed via autoselect command (DQ6 = 0). Customer-lockable versions allow writing custom data to the 256-byte region before one-time locking (DQ6 = 1), after which no further writes are possible. The region is physically isolated and inaccessible during normal array operations unless explicitly entered via command sequence.
Can the S29JL064J70TFI003 operate in both x8 and x16 data bus modes?
Yes - the device supports both 8-bit and 16-bit data widths via the BYTE# pin. When BYTE# is low, DQ7–DQ0 are active for byte-mode operation; when high, DQ15–DQ0 function as a full 16-bit bus. Address line A-1 is multiplexed onto DQ15 in byte mode to extend addressing range. This dual-width capability simplifies integration across 8-bit microcontrollers and 16-bit DSP platforms without external glue logic.
What distinguishes simultaneous read/write from standard NOR flash erase/program behavior?
Unlike conventional NOR flash that halts all reads during erase or program cycles, the S29JL064J70TFI003 divides memory into four independent banks, allowing reads from any non-busy bank while erasing or programming another. This eliminates latency penalties and enables true background operations - e.g., executing application code from Bank 1 while updating firmware in Bank 3 - without CPU intervention or polling overhead.
