Infineon Technologies S26KS128SDPBHV020

Overview

S26KS128SDPBHV020 from Infineon is a 128 Mb (16 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-plus temperature range (–40°C to +105°C) in 24-ball FBGA package for embedded boot code storage.

For engineers reviewing the S26KS128SDPBHV020 datasheet, S26KS128SDPBHV020 pinout, S26KS128SDPBHV020 application, or S26KS128SDPBHV020 equivalent, key selection criteria include HYPERBUS™ timing compliance (96 ns random access), RWDS-synchronized DDR read alignment, sector protection granularity, deep power-down current (4 µA), and AEC-Q100 grade 2 qualification for automotive control modules.

Technical Context

This 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#. The embedded algorithm controller (EAC) autonomously executes program/erase sequences without host intervention after command issuance.

It uses MIRRORBIT™ architecture enabling 16-bit word-wide accesses on 16-byte-aligned boundaries, with initial latency of 5–16 clock cycles and configurable burst modes (16/32/64-byte wrapped or linear). RWDS output is edge-aligned to data transitions during reads, while DCARS (DDR Center-Aligned Read Strobe) ensures precise capture timing at the host receiver.

FAQ

What is the purpose of the RWDS signal in S26KS128SDPBHV020?

RWDS (Read Data Strobe) is an output signal synchronized to read data edges on the DQ bus. It enables the host controller to accurately latch DDR-read data without relying solely on CK/CK# timing margins. RWDS transitions align with valid data windows during burst reads, reducing setup/hold timing constraints and improving signal integrity in high-speed layouts.

Does S26KS128SDPBHV020 support both 1.8 V and 3.0 V I/O operation?

No - S26KS128SDPBHV020 is specified for 1.8 V I/O operation only, with differential CK/CK# and RWDS. The "3.0 V / 1.8 V" designation in the family datasheet refers to the broader HYPERFLASH™ portfolio; this specific part number (PBHV020 suffix) denotes 1.8 V I/O, industrial-plus temperature, and FBGA packaging.

How does the embedded algorithm controller (EAC) affect firmware update design?

After issuing a program or erase command sequence to the command address space, the EAC autonomously executes the full algorithm - including voltage ramping, verify steps, and status reporting - without host CPU intervention. This allows the host to enter low-power states or service other tasks during flash operations, simplifying real-time update scheduling in safety-critical systems.

Can S26KS128SDPBHV020 be used with standard SPI or QSPI controllers?

No - it requires a native HYPERBUS™ master interface capable of DDR signaling, differential clock handling, and RWDS synchronization. Standard SPI/QSPI controllers lack the timing control, signal count, and protocol stack needed to drive HYPERBUS™ commands, addresses, and data. Dedicated SoC peripherals (e.g., NXP i.MX RT117x, Renesas RZ/G2L) or FPGA IP blocks are required.
