Product details

Overview

S29JL064J70TFA000 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 independently addressable banks, 55–70 ns access time, and integrated secured silicon region with factory-locked 16-byte ESN for secure boot in embedded systems.

For engineers reviewing the S29JL064J70TFA000 datasheet, S29JL064J70TFA000 pinout, S29JL064J70TFA000 application, or S29JL064J70TFA000 equivalent, key selection criteria include bank-level concurrency support, JEDEC CFI compliance, hardware sector protection, WP#/ACC dual-function pin behavior, and FBGA/TSOP package compatibility in industrial control 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 JEDEC command set.

It uses internal charge pumps to generate high-voltage programming/erasing signals from a single 3.0 V supply, supports both byte (DQ7–DQ0) and word (DQ15–DQ0) data interfaces via BYTE# control, and integrates hardware reset (RESET#), ready/busy (RY/BY#), and write protect/acceleration (WP#/ACC) functions with defined timing margins per AC spec.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (4,194,304 × 16-bit or 8,388,608 × 8-bit)
Access Time (tACC)	70 ns max - defines minimum clock-to-data valid delay in high-speed read cycles
Program Time	7 µs/word typical with acceleration - enables rapid field firmware updates
Read Current	10 mA at 5 MHz - determines power budget for active instruction fetch in microcontroller boot loaders
Standby Current	200 nA - supports ultra-low-power retention in battery-backed systems
Cycling Endurance	1 million cycles/sector - qualifies for frequent OTA update partitions in edge devices
Data Retention	20 years typical - ensures long-term reliability of stored calibration or configuration data

Pinout & Package

Package: 48-ball Fine-pitch BGA (VBK048 footprint); RoHS-compliant, 7 mm × 9 mm body, 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
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 logic; prevents bus contention during multi-device operation
WP#/ACC	Hardware Write Protect / Program Acceleration	Active-low pin that locks sectors 0/1/140/141 when asserted, or enables faster programming when pulsed
RY/BY#	Ready/Busy Output	Open-drain status signal indicating active erase/program cycle completion
RESET#	Hardware Reset	Forces device into read mode and clears internal state machine on power-up or fault recovery
BYTE#	Bus Width Select	Active-low input selecting 8-bit (DQ7–DQ0) or 16-bit (DQ15–DQ0) data interface

Key Features

Feature	Design Value
Simultaneous Read/Write	Zero-latency concurrent operation across four banks enables real-time firmware execution during background update
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 interruption of sector erase to service urgent read/program requests without data loss or timing violation
JEDEC CFI Compliance	Enables automatic detection of device geometry, command set, and timing parameters by host bootloader or flash utility
Zero Power Operation	Automatic sleep mode reduces current to 200 nA after address stability, eliminating need for external power gating

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29JL064J70TFI010	Same die, TSOP-48 package instead of FBGA-48; identical timing and feature set	Preferred for through-hole or legacy PCB layouts with space for larger footprint	Select when board assembly uses TSOP carriers or requires manual rework accessibility
S29GL064S90TFI010	64-Mb GL-series part with 90 ns access, no simultaneous read/write; different bank architecture	Lacks zero-latency concurrency; suited for cost-sensitive, non-real-time firmware storage	Choose only if background operation is unnecessary and lower performance is acceptable

Compared with S29JL064J70TFA000, the TSOP variant offers identical functionality in a different package for layout flexibility, while the GL-series alternative sacrifices simultaneous operation for reduced cost and simpler control logic-making it unsuitable for real-time update scenarios.

FAQ

What is the function of the WP#/ACC pin on S29JL064J70TFA000?

The WP#/ACC pin serves dual roles: when held low, it hardware-protects sectors 0, 1, 140, and 141 from accidental erase/program; when pulsed low during programming, it activates accelerated write timing (7 µs/word). Its behavior is defined in the datasheet's Section 8.11 and confirmed in AC timing Table 17.4.

Does S29JL064J70TFA000 support true background erase?

Yes-it supports true background erase via Erase Suspend/Erase Resume commands. While erasing one sector, the host can read from or program any other non-erasing sector, then resume the suspended erase. This is implemented in hardware and verified in Section 8.10 and Figure 11 on page 31 of the datasheet.

How is the Secured Silicon Region used in secure boot implementations?

The Secured Silicon Region provides a 256-byte OTP sector where Infineon pre-programs a verifiable 16-byte random ESN. The DQ6 indicator bit confirms factory lock status, enabling cryptographic binding of firmware images to the unique device identity-used in bootloader signature verification per Section 8.13 and Figure 22.

Can S29JL064J70TFA000 operate in both 8-bit and 16-bit modes on the same PCB design?

Yes-BYTE# pin selects bus width: low enables 16-bit mode (DQ15–DQ0), high enables 8-bit mode (DQ7–DQ0), with DQ15/A-1 repurposed as address LSB. This dual-mode support is electrically validated in Section 8.1 and AC test condition Table 15, allowing flexible MCU interface design.
