Infineon Technologies S29VS128RABBHW000

Overview

S29VS128RABBHW000 from Spansion is a 128-Mbit (16-MB) 1.8 V burst-mode MirrorBit Flash memory with multiplexed address/data interface (ADM), eight-bank architecture, and simultaneous read/write capability across independent banks. It delivers 108 MHz synchronous operation, 72.34 ns latency, and supports JEDEC-standard command set for embedded wireless baseband and application processors.

For engineers reviewing the S29VS128RABBHW000 datasheet, S29VS128RABBHW000 pinout, S29VS128RABBHW000 application, or S29VS128RABBHW000 equivalent, key selection criteria include 1.7–1.95 V single-supply operation, 32-word write buffer performance, hardware sector protection via VPP, CFI support, and FBGA-44 package compatibility with high-density mobile SoC designs.

Technical Context

This device implements Spansion's 65 nm MirrorBit technology with asynchronous and synchronous (burst) read modes, including programmable linear and wrap-around burst configurations. It features an eight-bank architecture enabling zero-latency concurrent access - one bank executing erase/program while another performs read operations.

The RDY output provides handshaking control, and status register bits report program/erase completion, suspend/resume state, and protection status. Command execution follows JEDEC 42.4 standard sequences, with hardware reset (RESET#) and software reset options supporting robust system initialization and recovery.

Key Specifications

Pinout & Package

Package: 44-ball FBGA (6.2 mm × 7.7 mm × 1.0 mm, ball pitch 0.8 mm), RoHS-compliant, suitable for fine-pitch automated assembly in mobile and networking modules.

Key Features

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar burst-mode parallel NOR flash applications.

Compared with S29VS128RABBHW000, the Cypress alternative requires voltage translation and sacrifices burst throughput, while the Macronix part increases board area and removes critical firmware security features - making the Spansion device optimal for new 1.8 V mobile and automotive designs demanding performance, density, and security.

Availability

S29VS128RABBHW000 is available at Aetrix Electronics and suitable for mobile baseband processors, wireless access points, and industrial HMI controllers requiring stable component supply, long-term lifecycle support, and verified flash interoperability.

Supply support for S29VS128RABBHW000 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Spansion Inc. was a leading developer of flash memory and microcontrollers, formed from the merger of AMD's and Fujitsu's flash businesses; acquired by Cypress Semiconductor in 2015 and later integrated into Infineon Technologies.

This device belongs to the S29VS/XS-R MirrorBit Flash family, designed specifically for high-performance, low-voltage embedded systems where simultaneous code execution and firmware update coexistence are mandatory - especially in wireless infrastructure and mobile SoC platforms.

FAQ

Is S29VS128RABBHW000 pin-compatible with other S29VS-R series devices?

Yes - all S29VS-R variants (e.g., S29VS256R) share identical 44-ball FBGA mechanical layout and pin assignment. Differences are limited to internal memory density and timing parameters; no PCB redesign is needed when scaling capacity within the same speed grade and temperature range.

Does this device support XIP (eXecute-In-Place) operation?

Yes - its synchronous burst read mode with 6.75 ns access time and RDY handshaking enables direct code execution from flash without copying to RAM. The 108 MHz clock and linear/wrap-around burst modes are optimized for continuous instruction fetch in ARM and MIPS-based application processors.

What is the role of the VPP pin beyond factory programming?

VPP serves dual functions: during manufacturing, it accelerates programming to 9 µs/word; in system operation, it enables hardware-based sector lock/unlock - applying VPP voltage (≥2.7 V) permanently protects designated sectors from accidental writes until next power cycle, enhancing field update safety.

How does the Secure Silicon Region differ from standard flash sectors?

The Secure Silicon Region consists of two dedicated 128-word sectors (factory and customer) physically isolated from the main array. These sectors are inaccessible via standard command sequences, require special unlock keys, and retain data independently - used for storing cryptographic keys, device IDs, or calibration constants immune to firmware overwrite.
