Infineon Technologies S29PL064J70BFI072

Overview

S29PL064J70BFI072 from Infineon Technologies (formerly Cypress) is a 64-Mbit (4 Mword × 16-bit) 3.0 V-only Page Mode Flash memory with Simultaneous Read/Write capability, FlexBank architecture, and Enhanced VersatileI/O™ supporting 3 V I/O. It features 4 independent banks (A–D), 8-word page size, 20 ns page access time, and operates across 2.7–3.6 V for battery-powered embedded systems requiring nonvolatile code/data storage with in-system reprogrammability.

For engineers reviewing the S29PL064J70BFI072 datasheet, S29PL064J70BFI072 pinout, S29PL064J70BFI072 application, or S29PL064J70BFI072 equivalent, key selection criteria include bank-level concurrent read/write operation, persistent/password sector protection, CFI compliance, 1 million erase/program cycles, and 48-ball Fine-pitch BGA (VBK048) package compatibility.

Technical Context

This device implements a FlexBank architecture with four physically isolated banks (A–D), enabling true simultaneous read from one bank while erasing or programming another-eliminating latency between operations. Each bank supports independent command execution, and bank boundaries are fixed per density: Bank A/D = 8 Mbit each, Banks B/C = 24 Mbit each for the PL064J variant.

Enhanced VersatileI/O™ fixes all I/O and control pin voltage tolerance and output drive to the VIO pin level (3 V for PL064J), decoupling interface signaling from core VCC. Sector protection is implemented via three complementary mechanisms: hardware WP# pin lock, persistent PPB bits, and 64-bit password-secured locking-each enforceable at individual sector or group level without requiring high voltage.

FAQ

What is the function of the VIO pin on the S29PL064J70BFI072?

The VIO pin sets the input threshold and output drive voltage for all I/O and control signals-including DQ0–DQ15, CE#, OE#, WE#, RY/BY#, RESET#, and WP#/ACC. For the PL064J variant, VIO must be tied to 3 V to ensure correct 3 V logic-level operation. This eliminates external level shifters when interfacing with 3 V microcontrollers or FPGAs.

Does the S29PL064J70BFI072 support true simultaneous read and write across different banks?

Yes. The FlexBank architecture divides the 64 Mbit array into four independent banks (A–D). While a program or erase operation executes in one bank, the host can issue read commands to any other bank with zero latency-verified by RY/BY# status and supported by hardware state-machine isolation per bank.

How is sector protection implemented, and what are the differences between Persistent and Password modes?

Persistent Sector Protection uses PPB (Persistent Protection Bit) flags stored in nonvolatile registers to lock sectors permanently until explicitly unlocked via command sequence at VCC. Password Sector Protection requires a 64-bit user-defined key to unlock protected sectors-both methods operate independently and can be combined. Neither requires high voltage; both survive power cycles.

Is the S29PL064J70BFI072 compatible with standard JEDEC Flash programmers?

Yes. It implements the JEDEC 42.4 single-power-supply Flash command set and supports standard programming equipment via its parallel x16 interface. No 12 V VPP is needed. Autoselect mode returns manufacturer and device IDs, and CFI query enables automatic tool configuration-confirmed in Cypress/Infineon documentation 002-00615 Rev. *F.
