Nexperia USA Inc. S26KS512SDPBHA020

Overview

S26KS512SDPBHA020 from Infineon Technologies is a 512 Mb (64 MB) HYPERFLASH™ NOR flash memory with HYPERBUS™ DDR interface, operating at 1.8 V I/O and supporting differential clock (CK/CK#), 8-bit DQ bus, and RWDS read strobe. It delivers 333 MBps sustained read throughput at 166 MHz, features 256-KB uniform sectors, ECC 1-bit correction/2-bit detection, and supports industrial temperature range (–40°C to +85°C) in 24-ball FBGA package.

For engineers reviewing the S26KS512SDPBHA020 datasheet, S26KS512SDPBHA020 pinout, S26KS512SDPBHA020 application, or S26KS512SDPBHA020 equivalent, key selection criteria include DDR HYPERBUS™ timing compliance, RWDS-synchronized read latency (96 ns initial access), sector protection granularity, deep power-down current (8 µA), and AEC-Q100 grade compatibility for automotive boot code storage.

Technical Context

The device implements a synchronous DDR interface where command/address and data share the 8-bit DQ bus, with dual-edge sampling referenced to CK/CK#. Its embedded algorithm controller (EAC) autonomously executes program/erase sequences without host intervention, using a 512-byte write buffer to achieve ~1 MBps buffered programming.

HYPERFLASH™ uses MIRRORBIT™ architecture enabling 16-bit word-wide accesses on 8-bit DDR bus; read bursts support configurable wrapped (16/32/64 bytes) or linear modes, and DCARS (DDR Center-Aligned Read Strobe) aligns read data edges to RWDS transitions-not clock edges-ensuring timing robustness across voltage/temperature variations.

FAQ

What is the purpose of the RWDS signal in S26KS512SDPBHA020?

RWDS (Read Data Strobe) is an output signal synchronized to read data transitions-not the clock-and indicates valid data windows on the DQ bus. It enables precise edge-aligned sampling of DDR read data per the DCARS protocol, eliminating setup/hold timing dependency on CK/CK# skew and improving robustness across voltage/temperature variations.

Does S26KS512SDPBHA020 support both 1.8 V and 3.0 V operation?

No-S26KS512SDPBHA020 is a 1.8 V I/O device with differential clock (CK/CK#) and supports only 1.8 V VCCQ. The 3.0 V variants (e.g., S26KL512S) use single-ended clock and different timing; mixing voltages risks interface failure and violates absolute maximum ratings.

How does the 512-byte write buffer improve programming efficiency?

The internal 512-byte buffer allows host to issue one command followed by up to 512 bytes of data, reducing command overhead. Buffer programming achieves ~1 MBps throughput-over 200× faster than single-word programming (4 KBps)-and minimizes host CPU intervention during firmware updates.

Can S26KS512SDPBHA020 be used in AEC-Q100 Grade 1 applications?

No-this specific part number (PBHA020 suffix) is rated for Industrial (–40°C to +85°C) and Automotive Grade 2 (–40°C to +105°C). Grade 1 (–40°C to +125°C) requires PBHA120 or PBHA220 suffix variants, which undergo extended temperature screening and qualification testing per AEC-Q100 Rev G.
