Infineon Technologies S29PL064J55BFI070

Overview

S29PL064J55BFI070 from Infineon Technologies (formerly Cypress) is a 64-Mbit (4 Mword × 16-bit) 3.0 V-only Page Mode Flash memory with FlexBank architecture, Enhanced VersatileI/O™, and simultaneous read/write operation across four independent banks. It delivers 20 ns page access, 55 ns random access, 1 million erase/program cycles per sector, and 20-year data retention - deployed in industrial control firmware storage where fast in-system reprogramming and bank-level concurrency are required.

For engineers reviewing the S29PL064J55BFI070 datasheet, S29PL064J55BFI070 pinout, S29PL064J55BFI070 application, or S29PL064J55BFI070 equivalent, key selection criteria include its 48-ball Fine-pitch BGA (VBK048) package, 2.7–3.6 V single-supply operation, persistent/password sector protection, CFI compliance, and zero-latency bank switching capability for real-time firmware updates.

Technical Context

This device implements a 4-bank FlexBank architecture enabling concurrent read from one bank while erasing or programming another - eliminating latency between host command execution and memory access. Each bank supports independent sector erase (4 KiB sectors), with Bank A and D sized at 8 Mbit (4 Kw × 8 + 32 Kw × 15) and Banks B/C at 24 Mbit (32 Kw × 48) each.

Enhanced VersatileI/O™ fixes I/O voltage to 3.0 V via the VIO pin, ensuring signal integrity across mixed-voltage systems. Sector protection combines hardware WP#/ACC control, persistent PPB locking, and 64-bit password-secured regions - all configurable in-system at V_CC without high-voltage programming.

FAQ

Does S29PL064J55BFI070 support true simultaneous read and write across different banks?

Yes. The FlexBank architecture enables two independent operations - e.g., reading from Bank A while erasing Bank B - with zero latency switching. This is confirmed in Section 2 and Table 1 of the datasheet (Document Number 002-00615 Rev. *F), where bank sizes and concurrent operation capability are explicitly defined.

What is the function of the VIO pin, and is it mandatory to connect?

The VIO pin sets the I/O voltage reference for all control inputs and DQ lines to 3.0 V. It must be connected to 3.0 V; leaving it floating or connecting to other voltages violates the Absolute Maximum Ratings (Section 17) and risks undefined behavior or damage. This is specified in the "Enhanced VersatileI/O™" section on page 2.

Can the Secured Silicon Sector be programmed using standard command sequences?

No. Access to the Secured Silicon Sector requires a dedicated 6-byte unlock sequence (0xAA, 0x55, 0x80, 0xAA, 0x55, 0x10) followed by the autoselect command, as defined in Section 15.4. Standard program commands will not write to this region without first entering secured silicon mode.

Is the 48-ball BGA package (VBK048) compatible with standard reflow profiles?

Yes. The VBK048 package complies with IPC/JEDEC J-STD-020D moisture sensitivity level 3 and supports standard Pb-free reflow profiles with peak temperature ≤260°C. Thermal characteristics and soldering guidelines are provided in Section 23 (Physical Dimensions) and Appendix A of the datasheet.
