Product details

Overview

S29JL064J70BHI003 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 70 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 retention and in-system reprogramming.

For engineers reviewing the S29JL064J70BHI003 datasheet, S29JL064J70BHI003 pinout, S29JL064J70BHI003 application, or S29JL064J70BHI003 equivalent, key selection criteria include simultaneous bank operation capability, 256-byte secured silicon sector lockability, 70 ns tACC timing, 48-ball FBGA package compatibility, and hardware write protection via WP#/ACC pin.

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. Sector protection is enforced via hardware WP#/ACC and software command sequences, with temporary unprotect allowing in-system updates to protected boot sectors.

It supports Common Flash Interface (CFI) for automatic parameter detection, erase suspend/resume for interruptible erase cycles, and dual-mode data bus (DQ15/A−1 pin for byte/word mode selection). Status reporting uses RY/BY# pin, DQ7 polling, and DQ6/DQ2 toggle bits-no external status controller 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 boot loader + application firmware in space-constrained designs
Access Time (tACC)	70 ns max - defines minimum clock cycle for reliable read access in high-speed microcontroller interfaces
Supply Voltage	2.7–3.6 V single VCC - eliminates need for separate VPP programming voltage; compatible with modern 3.3 V logic rails
Active Read Current	10 mA at 5 MHz - enables low-power operation in battery-backed or energy-sensitive embedded systems
Standby/Sleep Current	200 nA typical - allows persistent state retention during extended system sleep without capacitor hold-up
Cycling Endurance	1 million cycles per sector - supports frequent field firmware updates over product lifetime
Data Retention	20 years typical - ensures long-term reliability of stored configuration and calibration data

Pinout & Package

Package: 48-ball Fine-pitch BGA (VBK048 footprint), RoHS-compliant, 7 mm × 9 mm body size, 0.8 mm ball pitch.

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 byte-mode LSB addressing
DQ15–DQ0	Data I/O (x16)	16-bit bidirectional data bus; DQ15 doubles as A−1 in byte mode for seamless 8/16-bit interface adaptation
CE#, OE#, WE#	Control Enables	Standard asynchronous control signals; CE# gating enables low-power bank isolation; no bus contention during multi-device sharing
WP#/ACC	Hardware Write Protect / Acceleration	Active-low pin: WP# permanently disables programming/erasing of boot sectors 0,1,140,141; ACC enables faster 7 µs/word programming
RY/BY#	Ready/Busy Output	Open-drain active-low signal indicating internal operation completion - eliminates need for software polling in time-critical systems
RESET#	Hardware Reset	Forces device into read mode and clears internal state machine - 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 path - simplifies migration between microcontroller families

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29JL064J60BHI003	60 ns access time (vs. 70 ns); identical bank architecture, pinout, and feature set	Better suited for systems with tighter timing margins, e.g., high-clock-rate ARM Cortex-M7 MCUs	Select when system timing budget requires sub-70 ns read latency; otherwise, S29JL064J70BHI003 offers cost advantage
S29JL064J55BHI003	55 ns access time; same voltage range, package, and command set	Targeted at performance-critical applications like FPGA configuration storage with fast startup requirements	Choose only if 55 ns tACC is mandatory; verify board-level signal integrity supports faster edge rates

Compared with S29JL064J60BHI003 and S29JL064J55BHI003, the S29JL064J70BHI003 trades 15–25 ns slower access for improved noise margin and lower power consumption in thermally constrained industrial enclosures, making it optimal for cost-sensitive, reliability-focused deployments.

FAQ

What is the function of the WP#/ACC pin on S29JL064J70BHI003?

The WP#/ACC pin serves dual functions: as WP# (Write Protect), it hardware-locks sectors 0, 1, 140, and 141 against accidental program/erase operations regardless of software protection status; as ACC (Acceleration), it enables accelerated 7 µs/word programming when driven high during write cycles. This dual-role pin eliminates need for external logic to manage protection and performance modes.

How does the Secured Silicon Region differ between factory-locked and customer-lockable versions?

Factory-locked Secured Silicon Region contains a verifiable 16-byte random Electronic Serial Number and is permanently read-only; customer-lockable versions allow writing custom data before one-time locking. The DQ6 bit indicates lock type: 0 = factory locked, 1 = customer locked. Once locked, neither version permits modification - ensuring irreversible identity binding or secure code storage.

Can S29JL064J70BHI003 operate in both 8-bit and 16-bit data bus configurations?

Yes. The BYTE# pin selects bus width: low enables 16-bit mode (DQ15–DQ0 active); high enables 8-bit mode (DQ7–DQ0 active, with DQ15 repurposed as A−1 address bit). This flexibility allows direct interfacing with both 8-bit microcontrollers (e.g., legacy 8051 derivatives) and 16-bit processors (e.g., TI C2000) without level-shifting or glue logic.

What is the practical impact of erase suspend/resume functionality in real-world applications?

Erase suspend/resume allows pausing a sector erase to immediately read or program another sector - essential for maintaining system responsiveness during firmware updates. In an industrial HMI, this enables displaying progress indicators or handling user inputs while background erase proceeds, avoiding UI freezes. Resume occurs automatically upon command, preserving erase timing accuracy without host intervention.
