S29PL032J70BFA073

Memory IC Overview

The Infineon S29PL032J70BFI073 is a 32 Mbit (2M x 16-bit) parallel NOR flash memory device from the PL-J family. It features a 70 ns access time and operates on a single 2.7 V to 3.6 V power supply. The component utilizes an 8.15 mm x 6.15 mm, 48-ball Fine-Pitch BGA package (VBK048). Key architectural features include Simultaneous Read/Write capability across four banks with zero latency switching, page mode operation for fast sequential reads, and Enhanced Versatile I/O (VIO) support. It supports industrial temperature ranges of -40°C to +85°C.

Memory IC Feature Summary

• Simultaneous Read/Write architecture allows continuous reading from one bank while executing erase or program operations in another bank with zero latency.
• FlexBank organization divides the memory into four separate banks, enabling flexible sector protection and independent operation.
• Enhanced Versatile I/O (VIO) control allows input voltages and output levels to be determined by the voltage on the VIO pin, supporting 3.0 V I/O levels.
• Includes hardware data protection features such as a Ready/Busy# pin, hardware reset pin, and persistent sector protection.

Memory IC Applications

• Code storage in embedded systems requiring simultaneous execution and modification
• Industrial applications needing robust sector protection and wide operating temperatures
• Battery-powered devices utilizing single-supply read, erase, and program operations
• Systems requiring fast page-mode access for efficient data retrieval

Memory IC Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type, speed bin, and temperature range. Confirm current availability status as this component may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints for the 48-ball FBGA package. Cross-reference the VIO requirements with system interface voltages.

Memory IC Selection Notes

Select this component when simultaneous read/write operations are required to improve system throughput without waiting for erase cycles. The 32 Mbit density suits applications needing moderate code storage with high reliability. Ensure the design accommodates the 48-ball FBGA package dimensions and thermal requirements. Verify that the 3.0 V VIO level matches the host controller's I/O standards.

Memory IC Part Context

This device belongs to the S29PL-J family of 3 V-only Page Mode and Simultaneous Read/Write Flash memories. It is manufactured using 110-nm process technology. The PL-J series is designed for high performance and flexibility, offering both top and bottom boot sectors. It is backward compatible with standard JEDEC command sets and other legacy flash families.

Memory IC Replacement Considerations

S29GL064S70BHI033 is listed as a manufacturer recommended substitute. Note that the substitute has a different density (64 Mbit vs 32 Mbit) and may require software or hardware adjustments. Verify electrical and mechanical compatibility before replacement.
