Infineon Technologies S29WS512PABBFW000

Overview

S29WS512PABBFW000 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. It supports zero-latency concurrent read and write across two independent banks, delivers 104 MHz synchronous burst access with 7.6 ns tBACC, and features hardware write protection, secured silicon sector, and CFI compliance for embedded boot and code storage applications in wireless baseband processors.

For engineers reviewing the S29WS512PABBFW000 datasheet, S29WS512PABBFW000 pinout, S29WS512PABBFW000 application, or S29WS512PABBFW000 equivalent, key selection criteria include simultaneous bank operation capability, 84-ball FBGA package compatibility, 1.7–1.95 V single-supply operation, 100,000-cycle sector endurance, and support for suspend/resume during program/erase.

Technical Context

This device implements a sixteen-bank architecture with 32 Mwords of addressable space, enabling true concurrent access: one bank executes burst reads while another performs buffered programming or sector erase. Its dual-boot sector configuration (four 16 Kword sectors at top and bottom) and RDY handshaking support deterministic firmware update timing in real-time systems.

The 84-ball FBGA package supports MCP-compatible layout with dedicated AVD#, ACC, and WP# pins for acceleration, address validation, and hardware sector lock. Clock-synchronized burst mode operates independently of asynchronous control, and CFI query structure enables automatic driver initialization in host boot ROMs.

FAQ

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

The S29WS512PABBFW000 supports up to 104 MHz in synchronous burst mode, achieving a 7.6 ns burst access time (tBACC). This frequency is validated across the full operating voltage range (1.70–1.95 V) and temperature range (–25°C to +85°C), with CLK input meeting specified setup/hold timing relative to AVD# and address transitions.

How does the RDY pin function during simultaneous read/write operations?

RDY asserts low when valid burst data is ready for read access and deasserts high when internal program or erase operations complete. During simultaneous operation, RDY reflects the status of the read bank only-write/erase completion is indicated separately via status register bits, enabling independent flow control for each bank.

Can the secured silicon sector be erased or rewritten after initial programming?

No-the secured silicon sector consists of two 128-word regions (factory and customer) that can be permanently locked via persistent protection bits. Once locked, these regions are immune to standard erase commands and require hardware reset to re-enter secured mode; factory region contents are pre-programmed and unalterable by end users.

Is the 84-ball FBGA package compatible with standard PCB assembly processes?

Yes-the VBH084 package uses standard 0.80 mm ball pitch and Pb-free solder balls, qualified for reflow per J-STD-020. However, Cypress specifies strict handling: avoid ultrasonic cleaning, limit peak reflow temperature to ≤260°C, and ensure VCC/VCCQ ramp simultaneously to prevent latch-up or data corruption during power-up.
