Infineon Technologies S29JL064J60BHA000

Overview

S29JL064J60BHA000 from Infineon Technologies (formerly Cypress) is a 64-Mb simultaneous read/write flash memory organized as 4M × 16-bit or 8M × 8-bit, operating at 3.0 V only with 60 ns access time. It features four independent banks, zero-latency concurrent read/erase-program operations, and integrated hardware sector protection. Used in embedded boot code storage for industrial controllers requiring nonvolatile firmware persistence and in-system reprogrammability.

For engineers reviewing the S29JL064J60BHA000 datasheet, S29JL064J60BHA000 pinout, S29JL064J60BHA000 application, or S29JL064J60BHA000 equivalent, key selection criteria include simultaneous bank operation capability, secured silicon region support, JEDEC CFI compliance, 20-year data retention, and dual-boot sector architecture for fail-safe firmware updates.

Technical Context

The device implements a four-bank architecture-two 8 Mb banks (Bank 1 & Bank 4) with mixed 8 KB/64 KB sectors and two 24 Mb banks (Bank 2 & Bank 3) with uniform 64 KB sectors-enabling true background erase and program while reading from any non-busy bank. Sector addresses are fixed, but software-defined bank grouping allows flexible partitioning.

It supports Common Flash Interface (CFI), erase suspend/resume, data# polling (DQ7), toggle bits (DQ6/DQ2), and hardware status signaling via RY/BY#. The Secured Silicon Region provides a factory-locked 256-byte sector with verifiable 16-byte ESN or customer-lockable one-time programmable space.

FAQ

Is S29JL064J60BHA000 pin-compatible with earlier S29JL064J variants?

Yes-S29JL064J60BHA000 uses the same 48-ball FBGA (VBK048) package and identical pin mapping as all S29JL064J speed grades (55/60/70 ns). CE#, OE#, WE#, RY/BY#, RESET#, WP#/ACC, BYTE#, and address/data pins retain identical electrical behavior and timing relationships per Infineon Document 002-00856 Rev. *J.

Does this device support both x8 and x16 data bus widths?

Yes-BYTE# pin selects bus width: logic high enables 8-bit mode (DQ7–DQ0 active), logic low enables 16-bit mode (DQ15–DQ0 active). In x8 mode, A-1 (multiplexed on DQ15) becomes the LSB address; the device maintains full 64 Mb density in either configuration per Section 8.1 of the datasheet.

How is the Secured Silicon Region accessed and locked?

The Secured Silicon Region is accessed using the Enter Secured Silicon Region command sequence (00h on DQ7–DQ0, then specific unlock cycles). Factory locking is permanent and sets DQ6=0; customer locking uses the Customer Lock command and sets DQ6=1. Once locked, no further writes are possible-verified via autoselect function per Section 8.13.

What happens during an erase suspend operation?

When Erase Suspend is issued, the ongoing sector erase halts immediately. The device enters read/program mode for any non-erasing sector, allowing host CPU to fetch data or update other regions. Resume restores the suspended erase-no data loss occurs, and timing resumes from point of suspension per Section 8.10 and Figure 11-1.
