Product details
Overview
S29PL032J55BFI123 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 in-system programming without VPP. Used in industrial HMI firmware storage where concurrent code execution and background firmware updates are required.
For engineers reviewing the S29PL032J55BFI123 datasheet, S29PL032J55BFI123 pinout, S29PL032J55BFI123 application, or S29PL032J55BFI123 equivalent, key selection criteria include 4-bank FlexBank concurrency, 3V-only VIO compatibility, persistent/password sector protection, and 1M-cycle erase endurance - all validated for embedded control firmware retention and field-upgradeable systems.
Technical Context
This device implements a true Simultaneous Read/Write architecture using four physically isolated banks (A–D), enabling zero-latency switching between read and program/erase operations in different banks. Each bank supports independent command execution, 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 the PL032J variant.
Enhanced VersatileI/O™ fixes I/O voltage tolerance and output drive to the VIO pin level (3.0 V for PL032J), decoupling interface signaling from core VCC (2.7–3.6 V). Sector protection combines persistent locking (PPB), password-secured 64-bit authentication, and hardware WP#/ACC pin control - all operating at standard VCC without high-voltage assist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (2 Mwords × 16-bit bus), enabling compact firmware image storage with x16 parallel interface efficiency. |
| Access Time | 55 ns random access / 20 ns page access - meets real-time boot latency requirements for industrial controllers. |
| Operating Voltage | 2.7–3.6 V VCC with 3.0 V VIO - supports single-supply battery-powered and 3.3 V rail designs without level shifters. |
| Erase Endurance | 1 million cycles per sector - validated for frequent field firmware updates over 10+ years of deployment. |
| Data Retention | 20 years typical at 125°C - ensures long-term reliability in automotive-grade and industrial temperature environments. |
| Bank Architecture | 4 independent FlexBank units (A–D), allowing concurrent read from one bank while erasing/programming another - eliminates CPU stall during firmware patching. |
| Protection Modes | Persistent Sector Protection (PPB), Password Sector Protection (64-bit user-defined), and hardware WP# - provides layered security for bootloader and calibration data. |
Pinout & Package
Package: 48-ball Fine-pitch BGA (VBK048), 8.15 mm × 6.15 mm, 0.5 mm pitch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 2 Mword addressing; A0–A1 select byte within 16-bit word. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with 3.0 V VIO-tolerant drivers and receivers - no external level translation needed. |
| CE#, OE#, WE# | Chip/Output/Write Enable | Standard asynchronous control signals; CE# enables device, OE# gates output, WE# initiates write - compatible with legacy microcontroller buses. |
| RY/BY# | Ready/Busy Output | Open-drain status indicator: low during active program/erase, high when ready - enables hardware polling without software overhead. |
| RESET# | Hardware Reset Input | Asynchronous active-low reset that forces device into reading array mode - critical for recovery after power brownout or watchdog timeout. |
| WP#/ACC | Write Protect/Acceleration | VIL = locks top/bottom 4K-word sectors; VIH = unlocks; VHH = factory accelerated programming - dual-role pin simplifies board-level protection design. |
| VIO | I/O Supply Reference | Defines I/O voltage level (3.0 V for PL032J); separates interface signaling from core VCC - enables mixed-voltage system integration. |

FAQ
Does S29PL032J55BFI123 require a 12 V VPP supply for programming?
No. The device uses internally generated high voltages for erase and program operations. Only a single 2.7–3.6 V VCC supply is required - eliminating external charge pumps and simplifying power design for battery-powered and space-constrained applications.
What is the function of the VIO pin on S29PL032J55BFI123?
The VIO pin sets the I/O voltage reference for all control inputs and data pins at 3.0 V. This decouples interface signaling from core VCC, ensuring consistent timing and noise immunity - critical when interfacing with 3.3 V microcontrollers in mixed-voltage systems.
How does the Secured Silicon Sector differ from standard Flash sectors?
The Secured Silicon Sector is a dedicated 128-word region accessible only via a specific unlock sequence. Up to 64 words are factory-locked and cannot be modified; up to 64 are customer-lockable - providing tamper-resistant storage for cryptographic keys or calibration data not achievable in standard addressable sectors.
Can S29PL032J55BFI123 perform erase and read operations simultaneously?
Yes. Its FlexBank architecture divides memory into four independent banks (A–D). While erasing or programming in one bank (e.g., Bank B), the host can simultaneously read from another bank (e.g., Bank A) with zero latency - a hardware-enforced capability confirmed in the datasheet's Simultaneous Read/Write section.
