Infineon Technologies S29JL064J60BHI003

Overview

S29JL064J60BHI003 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, 4-bank architecture enabling zero-latency background erase/program, and integrated Secured Silicon Region for factory-locked 16-byte ESN - deployed in industrial control firmware storage and boot code retention systems.

For engineers reviewing the S29JL064J60BHI003 datasheet, S29JL064J60BHI003 pinout, S29JL064J60BHI003 application, or S29JL064J60BHI003 equivalent, key selection criteria include simultaneous bank operation capability, JEDEC CFI compliance, hardware sector protection, 20-year data retention, and FBGA/TSOP package compatibility with legacy 48-pin footprint designs.

Technical Context

The device implements a four-bank flash architecture (two 8 Mb + two 24 Mb banks), each with fixed sector sizes (8 KB and 64 KB), allowing any non-busy bank to be read during erase/program of another - enabling true background operations without software intervention. Bank grouping is configurable via system software to match application memory partitioning needs.

It supports Common Flash Interface (CFI) for standardized identification and command execution, includes Erase Suspend/Resume for interruptible erase cycles, and uses DQ7 polling and DQ6/DQ2 toggle bits alongside RY/BY# for real-time operation status feedback - all compliant with JEDEC 42.4 single-power-supply flash standards.

FAQ

What is the function of the WP#/ACC pin on S29JL064J60BHI003?

The WP#/ACC pin serves dual functions: as WP# (Write Protect), it permanently disables program/erase operations in boot sectors 0, 1, 140, and 141 regardless of software protection status; as ACC (Acceleration), it enables internal voltage boosting to reduce word-program time from 7 µs to ≤4 µs when asserted during programming sequences - verified in datasheet Section 8.11 and AC Characteristic Table 17.4.

Does S29JL064J60BHI003 support both 8-bit and 16-bit data bus configurations?

Yes - the BYTE# pin selects bus width: when low, DQ7–DQ0 operate as an 8-bit data bus with A-1 address input on DQ15; when high, DQ15–DQ0 form a full 16-bit bus. This dual-mode capability is implemented in silicon and confirmed in Section 8.1 (Word/Byte Configuration) and Pin Description Table 1 of the datasheet.

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

Factory-locked parts contain a verifiable 16-byte random Electronic Serial Number and support customer code programming via Cypress services; customer-lockable parts allow users to write arbitrary data and then permanently lock it. The Secured Silicon Customer Indicator Bit (DQ6) reads 0 for factory-locked and 1 for customer-locked devices - a hardware-level distinction validated through autoselect mode per Section 1.1 and 8.13.

Can S29JL064J60BHI003 perform true background erase while executing real-time read operations?

Yes - its four-bank architecture permits reading from any three banks while erasing or programming the fourth. Erase Suspend/Resume allows pausing an erase to service urgent read/program requests in other sectors, then resuming - enabling deterministic real-time response without sacrificing firmware update throughput, as detailed in Sections 1, 8.4, and 8.10.
