Spansion S26KL512SDABHB030

Overview

S26KL512SDABHB030 from Infineon is a 512 Mb (64 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 sectors and optional 4-KB parameter sectors, and operates across –40°C to +105°C (Industrial Plus grade) in automotive-grade AEC-Q100 Grade 2 applications.

For engineers reviewing the S26KL512SDABHB030 datasheet, S26KL512SDABHB030 pinout, S26KL512SDABHB030 application, or S26KL512SDABHB030 equivalent, key selection criteria include HYPERBUS™ timing compliance (96 ns tACC, 118 ns CS# access @ 166 MHz), ECC 1-bit correction/2-bit detection, configurable burst modes (16/32/64-byte wrapped or linear), and deep power-down current (8 µA typical).

Technical Context

This device implements a synchronous DDR interface using differential clock inputs (CK/CK#) and a center-aligned read strobe (DCARS) protocol, enabling two 8-bit transfers per clock cycle on the 8-bit DQ bus. Its embedded algorithm controller (EAC) autonomously executes program/erase sequences without host intervention, while the host interface controller (HIC) handles real-time signal capture and command forwarding.

It uses MIRRORBIT™ NOR architecture with page-aligned 32-byte random reads (two 16-byte half-pages), supports both wrapped and linear burst transactions, and integrates RSTO# for system-level power-on reset with user-configurable LOW period and INT# for ECC error or busy-to-ready interrupt signaling.

FAQ

What voltage levels does S26KL512SDABHB030 support for core and I/O operation?

The device supports dual-voltage operation: VCC/VCCQ = 1.8 V ±0.15 V for high-speed 166 MHz operation with differential clock, and VCC/VCCQ = 3.0 V ±0.3 V for 100 MHz operation with single-ended clock. Both configurations share the same 24-ball FBGA package and command set, enabling flexible system-level voltage scaling.

Does S26KL512SDABHB030 require external pull-up resistors on its control signals?

No external pull-ups are required on CS#, INT#, or RSTO# - all three signals have internal weak pull-up circuitry enabled after power-on reset. RWDS and DQ[7:0] are actively driven outputs/inputs and do not require termination resistors beyond standard DDR impedance matching (typically 40–50 Ω series or parallel).

How is ECC handled during read operations, and what happens on uncorrectable errors?

ECC logic runs transparently during every read access: 1-bit errors are corrected in hardware and data delivered error-free; 2-bit errors trigger the INT# pin assertion and set the corresponding status bit in the device's error flag register. No automatic retry or host intervention is required for correction, but uncorrectable errors must be handled by firmware via INT# polling or interrupt service routine.

Can S26KL512SDABHB030 be used with controllers lacking native HYPERBUS™ support?

Yes - it can interface with standard microcontrollers via GPIO-banged HYPERBUS™ protocol, though performance will be limited to ~10–20 MBps due to software timing constraints. Full 333 MBps throughput requires a dedicated HYPERBUS™ master IP block (e.g., in NXP S32G or Renesas RH850/U2A), which provides hardware-level DDR clock alignment and RWDS synchronization.
