Product details

Overview

S26KS256SDABHB030 from Infineon is a 256 Mb (32 MB) HYPERFLASH™ NOR flash memory with HYPERBUS™ DDR interface, 1.8 V I/O, differential clock (CK/CK#), 8-bit data bus (DQ[7:0]), and RWDS read strobe. It delivers 333 MBps sustained read throughput at 166 MHz, supports 256-KB uniform sector erase, and operates across –40°C to +105°C (Industrial Plus grade) in automotive-grade AEC-Q100 Grade 2 compliance.

For engineers reviewing the S26KS256SDABHB030 datasheet, S26KS256SDABHB030 pinout, S26KS256SDABHB030 application, or S26KS256SDABHB030 equivalent, key selection criteria include DDR burst timing (wrapped/linear), RWDS-synchronized read latency (96 ns initial access), ECC 1-bit correction/2-bit detection, and low-power deep power-down mode (4 µA typical).

Technical Context

This device implements a synchronous DDR interface over an 8-bit data bus using differential clocking (CK/CK#) and RWDS for precise read-data capture. Command, address, and data are all transferred in DDR fashion - two 8-bit transfers per clock cycle - enabling 16-bit word-aligned accesses with center-aligned command/address and edge-aligned read data relative to RWDS transitions.

The internal architecture separates host interface control (HIC) from embedded algorithm execution (EAC). The HIC handles real-time signal sampling and data transfer coordination, while the EAC autonomously executes program/erase algorithms, sector protection, and one-time-programmable (OTP) array management without host intervention.

Key Specifications

Memory Density	256 Mb (32 MB) - fixed capacity for boot code and firmware storage in resource-constrained systems
Interface Standard	HYPERTBUS™ DDR - 8-bit bus with differential clock and RWDS strobe, eliminating parallel address bus overhead
Max Read Throughput	333 MBps - achieved via 166 MHz clock × 2 transfers/cycle × 1-byte bus, enabling fast application loading
Initial Random Access Time	96 ns - latency from CS# assertion to first valid data, critical for deterministic boot timing

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed NOR flash applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Cypress S26KL256SDABHB020	Same die, identical electrical specs, but rated for Industrial (–40°C to +85°C) only - no AEC-Q100 certification	Lacks automotive qualification; unsuitable for under-hood or safety-critical ECUs	Select when cost sensitivity outweighs temperature or qualification requirements
Winbond W25Q256JWSIQ	Quad SPI interface (not DDR), 133 MHz max clock, no RWDS or differential clock - lower throughput (≈40 MBps)	Requires different controller IP and driver stack; no built-in ECC or sector protection granularity	Choose for legacy SPI-based designs where pin count and protocol simplicity are prioritized over speed

Compared with S26KL256SDABHB020, this part adds AEC-Q100 Grade 2 qualification and extended temperature operation; versus W25Q256JWSIQ, it delivers >8× higher read bandwidth and integrated ECC, justifying use in performance- and safety-critical edge nodes.

FAQ

What is the function of the RWDS pin?

RWDS (Read Write Data Strobe) is an output-only signal that indicates valid read data timing. During read operations, RWDS transitions align with the edges of DQ data, allowing the host controller to latch data reliably. It is not used during write operations and has no effect on command or address transfers.

Does S26KS256SDABHB030 support both 1.8 V and 3.0 V I/O operation?

No - this specific variant (S26KS256SDABHB030) is configured for 1.8 V I/O operation only, evidenced by its 'D' suffix (1.8 V I/O) and differential clock (CK/CK#) interface. The 3.0 V variants use single-ended clock and carry 'A' suffix (e.g., S26KS256SAABHB030).

How is sector protection implemented?

Sector protection uses both volatile lock bits (cleared on power cycle) and non-volatile OTP-based protection stored in a dedicated 1024-byte array. Each 256-KB sector can be individually locked/unlocked via command sequences, and parameter sectors (optional 4-KB × 8) support fine-grained configuration locking independent of main array access.

What is the wake-up time from Deep Power-Down mode?

The device requires 300 µs to exit Deep Power-Down mode and become ready for commands. This wake-up is initiated automatically upon CS# assertion and does not require external reset or clock stabilization - the internal oscillator resumes operation within the specified time.
