Infineon Technologies S29VS064RABBHW000

Overview

S29VS064RABBHW000 from Infineon Technologies (formerly Cypress) is a 64-Mbit (4M × 16-bit), 1.8 V-only, multiplexed-address burst-mode Flash memory IC with simultaneous read/write architecture across four independent banks. It supports zero-latency background erase/program in one bank while reading from another, operates within −25°C to +85°C, and uses a 44-ball Very Thin FBGA package. It is used in embedded boot code storage for industrial controllers requiring nonvolatile, high-reliability firmware retention.

For engineers reviewing the S29VS064RABBHW000 datasheet, S29VS064RABBHW000 pinout, S29VS064RABBHW000 application, or S29VS064RABBHW000 equivalent, key selection criteria include synchronous burst access time (7.6 ns), 100,000 program/erase cycles per sector, VersatileIO™ voltage flexibility, CFI compliance, and hardware sector protection via VPP = VIL.

Technical Context

This device implements a four-bank Simultaneous Read/Write architecture enabling true background operations: erase or program in one bank while performing continuous linear burst reads (8/16-word wrap-around) from another. Its VersatileIO™ interface decouples I/O voltage levels from core VCC by referencing VCCQ, supporting 1.8 V-compatible signaling without level shifters.

The memory uses MirrorBit® 65 nm process technology and integrates Embedded Program/Erase algorithms with auto-timed pulse widths and margin verification. It supports both asynchronous and synchronous (clock-driven) operation modes, with handshaking via RDY and programmable wait states for timing adaptation across host platforms.

FAQ

Is S29VS064RABBHW000 compatible with standard EPROM programmers?

Yes, the device supports programming in standard EPROM programmers using its JEDEC 42.4 command set. It accepts standard microprocessor write timings for command sequences and does not require specialized voltage sequencing beyond VCC (1.7–1.95 V) and optional VPP (9.0 V) for accelerated programming. Factory-erased state enables immediate use after programming.

What is the function of the VCCQ pin, and can it be tied to VCC?

VCCQ supplies power to the I/O buffers and sets input voltage thresholds and output drive levels via VersatileIO™. It must be supplied with 1.8 V ±0.1 V and cannot be tied directly to VCC unless VCC is regulated to match that exact range. Using mismatched voltages risks violating input tolerance or output drive specifications, potentially causing communication errors or latch-up.

How does the Dynamic Protection Bit (DYB) differ from hardware sector protection?

DYB provides in-system, software-controlled locking/unlocking of individual sectors at VCC level using command sequences, allowing dynamic field updates. Hardware sector protection activates automatically when VPP is pulled low (VIL), locking all sectors simultaneously - a failsafe mechanism during power instability or unauthorized access attempts.

Does S29VS064RABBHW000 support CFI query mode, and how is it accessed?

Yes, it fully supports Common Flash Interface (CFI) per JEDEC JESD68. CFI data is accessed by writing the CFI Query Command (0x98) to address 0x55 at offset 0x55, then reading the standardized parameter table from addresses 0x10–0x3F. This enables automatic driver detection and configuration in Linux MTD and U-Boot environments without hard-coded timing assumptions.
