Product details
Overview
S29PL032J70BFI073 from Infineon Technologies (formerly Cypress) is a 32-Mbit (2 M × 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 supports 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 deterministic bank-switching and secure sector protection are required.
For engineers reviewing the S29PL032J70BFI073 datasheet, S29PL032J70BFI073 pinout, S29PL032J70BFI073 application, or S29PL032J70BFI073 equivalent, key selection criteria include dual-bank zero-latency operation, VIO-controlled 3 V I/O tolerance, persistent/password sector protection, and 48-ball FBGA (VBK048) package compatibility with embedded boot code storage requirements.
Technical Context
This device implements a 4-bank FlexBank architecture enabling concurrent read from one bank while erasing or programming another - eliminating latency between execution and firmware update phases. Each bank is independently addressable, with Bank A and D sized at 4 Mbit (4 Kw × 8 + 32 Kw × 7) and Banks B/C at 12 Mbit (32 Kw × 24) for asymmetric firmware partitioning.
Enhanced VersatileI/O™ fixes all I/O and control pin voltage thresholds to the VIO supply (3 V), ensuring signal integrity in mixed-voltage systems. Sector protection combines persistent locking (PPB), password-secured 64-bit authentication, and hardware WP#/ACC input for factory-accelerated programming - supporting secure in-system reprogramming without external high-voltage sources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29PL032J70TFI073 | Same die, TSOP-56 package (20 × 14 mm); no BGA ball pitch constraints | Suitable for legacy PCBs with through-hole or wide-pitch routing; lacks BGA thermal performance | Select for cost-sensitive designs with existing TSOP footprint and no space constraints |
| MX29LV320EBTI-70G | 32 Mbit x16, 70 ns access, 3.0 V; no FlexBank or simultaneous operation; JEDEC-compatible only | Lacks zero-latency bank switching and password protection; limited to simple firmware storage | Select only when advanced features are unnecessary and legacy JEDEC toolchain support is mandatory |
Compared with S29PL032J70BFI073, the TSOP variant offers identical functionality in larger form factor, while the MX29LV320EBTI-70G sacrifices bank concurrency and security for broader toolchain compatibility - making the BGA version optimal for space-constrained, high-integrity embedded systems.

Manufacturer
Infineon Technologies is a global semiconductor leader headquartered in Munich, Germany, specializing in power management, sensing, connectivity, and memory solutions for industrial, automotive, and IoT applications.

FAQ
What is the purpose of the VIO pin on the S29PL032J70BFI073?
The VIO pin sets the voltage reference for all I/O and control pin logic thresholds and input voltage tolerances. For this part, VIO is fixed at 3 V, ensuring compatibility with standard 3.3 V microcontrollers without level-shifting circuitry. It does not power the core logic - that is handled separately by VCC (2.7–3.6 V).
How does the FlexBank architecture improve system performance?
FlexBank divides the 32-Mbit array into four independent banks (A–D), allowing simultaneous read from one bank while erasing or programming another. This eliminates CPU wait states during firmware updates, enabling real-time operation - for example, executing control code from Bank A while reprogramming calibration data in Bank C.
Can the Secured Silicon Sector be used to store cryptographic keys?
Yes. The Secured Silicon Sector provides up to 128 words (256 bytes) of dedicated, non-erasable memory accessible only via command sequence. Up to 64 words are factory-locked and 64 are customer-lockable, making it suitable for storing AES keys, device IDs, or calibration constants that must survive bulk erase operations.
Is the S29PL032J70BFI073 compatible with standard JEDEC Flash command sets?
Yes. It implements the JEDEC 42.4 single-power-supply Flash command set, ensuring backward compatibility with Am29F/LV/DL/PDL families and MBM29QM/RM/LV/DL/PDL devices. CFI (Common Flash Interface) compliance also enables automatic host software detection and configuration.
