Infineon Technologies S29VS064RABBHI000

Overview

S29VS064RABBHI000 from Infineon Technologies (formerly Cypress) is a 64-Mbit (4M × 16-bit), 1.8 V-only, multiplexed-address flash memory IC with simultaneous read/write capability across four independent banks, burst-mode support (8/16-word linear wrap-around), and VersatileIO™ interface for 1.8 V I/O compatibility. It operates from −25°C to +85°C in a 44-ball Very Thin FBGA package and is used in embedded boot code storage and firmware update systems requiring zero-latency background erase/program.

For engineers reviewing the S29VS064RABBHI000 datasheet, S29VS064RABBHI000 pinout, S29VS064RABBHI000 application, or S29VS064RABBHI000 equivalent, key selection criteria include synchronous burst latency (7.6 ns), sector erase time (350 ms for 8 kword sectors), dynamic protection bit (DYB) locking, CFI compliance, and simultaneous bank operation architecture.

Technical Context

This device implements a four-bank Simultaneous Read/Write architecture enabling concurrent execution of program/erase in one bank while reading from another - with zero latency handoff. Its VersatileIO™ feature decouples I/O voltage levels from VCC via dedicated VCCQ, supporting strict 1.8 V signaling integrity.

The memory uses MirrorBit® 65 nm process technology and supports JEDEC 42.4 command set compliance, including autoselect, secured silicon sector access (256 words), and hardware reset (RESET#) for state machine recovery. Burst mode is configured via internal registers and clock-synchronized timing.

FAQ

What is the function of the VCCQ pin on the S29VS064RABBHI000?

VCCQ sets the I/O voltage reference for all data pins (DQ0–DQ15) and controls both output drive strength and input voltage thresholds. It must be supplied with 1.8 V to ensure VersatileIO™ compatibility with 1.8 V host interfaces, and it operates independently from the core VCC supply.

Does the S29VS064RABBHI000 support true background erase?

Yes - using Erase Suspend/Resume, the device can pause an ongoing sector erase to read or program any non-erasing sector, then resume the original erase. This enables true background operation without interrupting system responsiveness, confirmed in Section 10.9 of the datasheet.

How is sector protection implemented on the S29VS064RABBHI000?

Sector protection uses two methods: Dynamic Protection Bit (DYB), which locks/unlocks individual sectors via command sequence at VCC level, and Hardware Sector Protection, which globally locks all sectors when VPP is pulled low. Both are documented in Sections 10.12 and 10.13 of the datasheet.

Can the S29VS064RABBHI000 be used in asynchronous-only systems without a clock signal?

Yes - the device supports full asynchronous operation using CE#, WE#, OE#, and AVD# signals. Clock (CLK) and RDY are required only for synchronous burst mode; all basic read, program, and erase functions operate without CLK, as specified in Section 10.2.
