Infineon Technologies S29WS512P0SBFW000

Overview

S29WS512P0SBFW000 from Cypress Semiconductor is a 512 Mb (32 M × 16-bit) 1.8 V simultaneous read/write NOR Flash memory using 90 nm MirrorBit™ technology, supporting zero-latency concurrent operations across two independent banks, with 104 MHz burst read capability and hardware write protection for top/bottom sectors - deployed in wireless baseband processors and LTE modem firmware storage.

For engineers reviewing the S29WS512P0SBFW000 datasheet, S29WS512P0SBFW000 pinout, S29WS512P0SBFW000 application, or S29WS512P0SBFW000 equivalent, key selection criteria include simultaneous bank operation support, 84-ball FBGA package compatibility, CFI compliance, 100,000-cycle sector endurance, and dual-boot sector architecture for fail-safe firmware updates.

Technical Context

This device implements a sixteen-bank architecture with 32 Mwords of addressable space, enabling true concurrent read and write on separate banks using dedicated address/data paths. It supports both synchronous burst (up to 104 MHz, 7.6 ns tBACC) and asynchronous access modes (80 ns tACC), with handshaking via RDY output and AVD#-controlled address latching.

Program and erase operations are managed through JEDEC-standard command sets, including suspend/resume, unlock bypass, and advanced sector protection via persistent bits or password methods. The Secured Silicon Sector provides factory- and customer-programmable 128-word regions for boot code integrity.

Equivalent & Alternatives

The following parts are listed as comparable options for similar simultaneous-read/write NOR Flash applications.

Compared with S29WS512P0SBFW000, the S29GL512S lacks true simultaneous operation and voltage compatibility, while MX29GL512F omits RDY signaling and CFI - making the S29WS512P uniquely suited for latency-critical, field-upgradable wireless firmware where deterministic burst timing and secure dual-boot are mandatory.

FAQ

What is the maximum clock frequency supported in synchronous burst read mode?

The S29WS512P0SBFW000 supports up to 104 MHz in synchronous burst read mode, achieving a 7.6 ns burst access time (tBACC). This frequency is validated across the full operating temperature range (–25°C to +85°C) and 1.70–1.95 V supply, with CLK input meeting specified setup/hold timing relative to AVD# and CE#.

Does this device support true simultaneous read and write across different memory banks?

Yes - the S29WS512P0SBFW000 implements a sixteen-bank architecture with physically separate data and address paths per bank pair, enabling zero-latency concurrent read from one bank and program/erase in another. This is confirmed in the block diagram and Section 7.8 of the datasheet, and requires no external arbitration logic.

How is hardware write protection implemented, and which sectors does WP# protect?

WP# is an active-low input that permanently disables program and erase functions in the four outermost sectors - specifically the topmost and bottommost 16 Kword sectors (total of eight 16 Kword sectors). Protection remains active regardless of software commands, and is effective across all VCC levels within specification.

Is the Secured Silicon Sector accessible via standard read commands, and what is its purpose?

No - the Secured Silicon Sector (128 words factory + 128 words customer) is isolated from normal array reads and requires explicit entry/exit command sequences (as defined in Section 10.3). Its purpose is to store immutable boot code, cryptographic keys, or calibration data immune to accidental overwrite or malware injection.
