Product details

Overview

S29PL032J55BFI073 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 delivers 55 ns random access time, 20 ns page access time, and supports 1 million erase/program cycles per sector with 20-year data retention. Used in industrial control firmware storage where concurrent code execution and field updates are required.

For engineers reviewing the S29PL032J55BFI073 datasheet, S29PL032J55BFI073 pinout, S29PL032J55BFI073 application, or S29PL032J55BFI073 equivalent, key selection criteria include 48-ball FBGA (VBK048) package compatibility, 2.7–3.6 V single-supply operation, persistent/password sector protection, CFI compliance, and zero-latency bank switching for real-time firmware patching.

Technical Context

This device implements a 4-bank FlexBank architecture enabling true concurrent operations: one bank can be erased or programmed while another serves active read requests with zero latency. Each bank supports independent command execution, and bank organization for S29PL032J is fixed as Bank A (4 Mbit), Bank B (12 Mbit), Bank C (12 Mbit), and Bank D (4 Mbit).

Enhanced VersatileI/O™ fixes I/O voltage tolerance and output drive to the VIO pin level (3 V for PL032J), decoupling interface signaling from core VCC. Sector protection includes both persistent (PPB-based) and password-secured (64-bit user-defined) modes, plus hardware WP#/ACC input for top/bottom boot block write lock at VIL.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL032N90TFI020	45 ns random access, 110 nm process, no VersatileI/O - fixed 3 V I/O, no VIO pin	Lacks zero-latency bank switching; uses uniform sector erase instead of FlexBank	Select when legacy JEDEC compatibility is prioritized over concurrent operation capability
MX29GL320EHTI-90G	90 ns access, 64 Mbit density, 3 V only, no CFI support - requires custom driver integration	No password protection or Secured Silicon Sector; limited sector protection granularity	Choose for cost-sensitive applications where firmware security and field update flexibility are secondary

Compared with S29PL032J55BFI073, the S29GL032N90TFI020 offers simpler timing but sacrifices concurrent operation and advanced protection, while the MX29GL320EHTI-90G trades performance and security for lower unit cost - making the S29PL032J optimal for secure, real-time upgradable systems.

FAQ

Does S29PL032J55BFI073 support true simultaneous read and write operations?

Yes. Its FlexBank architecture divides memory into four independent banks (A–D), allowing one bank to execute erase or program while another serves active read requests with zero latency. This is verified in the datasheet's Simultaneous Read/Write Block Diagram (page 10) and confirmed by the RY/BY# pin behavior during concurrent operations.

What is the function of the VIO pin on S29PL032J55BFI073?

The VIO pin sets the I/O voltage reference for all control inputs and data pins (DQ0–DQ15, CE#, OE#, WE#, etc.). For S29PL032J, VIO must be tied to 3 V, defining logic thresholds and drive strength - this decouples I/O signaling from core VCC and enables robust interfacing with 3 V microcontrollers without external level shifters.

How does password sector protection work on this device?

It uses a 64-bit user-defined password stored in the Secured Silicon Sector. After entering the correct password via the command sequence, users can unlock protected sectors for programming or erasure. Up to 64 words are customer-lockable; factory-locked portions prevent tampering with critical security parameters - detailed in Section 13 of the datasheet.

Is S29PL032J55BFI073 pin-compatible with earlier S29PL-J variants?

No. While sharing the same VBK048 package footprint, pin assignments differ between PL032J and PL064J/PL127J due to bank size and feature mapping. Specifically, A18–A19 and certain control signal routing vary; migration requires PCB layout revision and firmware register remapping per Table 1 and Pin Description (pages 16–17).
