Infineon Technologies S29PL064J70BFW122

Overview

S29PL064J70BFW122 from Infineon Technologies (formerly Cypress) is a 64-Mbit (4 Mword × 16-bit) single-supply 3.0 V 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, and supports in-system programming without VPP. Used in industrial HMI firmware storage where concurrent code execution and background update are required.

For engineers reviewing the S29PL064J70BFW122 datasheet, S29PL064J70BFW122 pinout, S29PL064J70BFW122 application, or S29PL064J70BFW122 equivalent, key selection criteria include bank-level erase/read concurrency, 3.0 V-only operation with 2.7–3.6 V tolerance, persistent/password sector protection, CFI compliance, and 48-ball FBGA (VBK048) package compatibility.

Technical Context

This device implements a 4-bank FlexBank architecture enabling zero-latency switching between read and program/erase operations-e.g., reading from Bank A while erasing Bank B. Each bank supports independent command execution, with Bank A and D sized at 8 Mbit (4 Kw × 8 + 32 Kw × 15), Banks B and C at 24 Mbit (32 Kw × 48).

Enhanced VersatileI/O™ fixes I/O voltage to 3.0 V via dedicated VIO pin, eliminating level-shifting requirements. Sector protection combines persistent locking (PPB), password-secured 64-bit authentication, and hardware WP# control for first/last two 4K-word sectors-enabling secure boot code partitioning and field firmware updates.

FAQ

Does S29PL064J70BFW122 support true simultaneous read and write across different banks?

Yes. The FlexBank architecture divides memory into four independent banks (A–D), allowing full read operations from one bank while executing erase or program commands in another. This zero-latency concurrency is confirmed in the datasheet's Simultaneous Read/Write Operation section and verified via RY/BY# status signaling.

What is the function of the VIO pin on S29PL064J70BFW122?

The VIO pin sets the I/O voltage reference for all control inputs and data pins (DQ0–DQ15, CE#, OE#, WE#, etc.). For PL064J devices, VIO is fixed at 3.0 V-ensuring consistent signal levels without external level shifters when interfacing with 3.3 V microcontrollers or FPGAs.

How does Password Sector Protection differ from Persistent Sector Protection in this device?

Password Sector Protection uses a user-defined 64-bit password to lock/unlock sectors, requiring authentication before modification. Persistent Sector Protection uses non-volatile PPB bits that retain lock state through power cycles without password entry. Both coexist: password protection adds dynamic access control; persistent protection ensures immutable boot sector lockdown.

Is the Secured Silicon Sector accessible after factory shipment?

Yes. The Secured Silicon Sector (up to 128 words) is accessible via documented command sequences (Enter/Exit Secured Silicon Sector). Up to 64 words are factory-locked and cannot be modified; up to 64 words are customer-lockable. Its contents survive full chip erase and support cryptographic key storage or calibration constants.
