Product details

Overview

S28HL01GTFPBHM033 from Cypress Semiconductor is a 1-Gb (128-MB), 3.0-V Semper® Flash NOR memory with Octal xSPI interface, ISO 26262 ASIL-B compliant safety architecture, EnduraFlex™ endurance partitioning, and 24-ball 8×8 mm BGA package. It delivers up to 332 MBps DDR read throughput at 166 MHz, supports 2.7–3.6 V supply, operates from −40 °C to +125 °C (AEC-Q100 Grade 1), and enables automotive boot code storage with SafeBoot recovery and SECDED ECC.

For engineers reviewing the S28HL01GTFPBHM033 datasheet, S28HL01GTFPBHM033 pinout, S28HL01GTFPBHM033 application, or S28HL01GTFPBHM033 equivalent, this page provides verified technical context, pin-level signal roles, real-world automotive and industrial use cases, and validated alternative flash devices with documented interface and endurance differences.

Technical Context

This device implements Cypress's 45-nm MirrorBit® technology with dual-bit-per-cell storage and supports both JEDEC JESD251-compliant Octal Peripheral Interface (8S-8S-8S/8D-8D-8D) and legacy SPI (1S-1S-1S). Its dual-controller architecture separates Host Interface Controller (HIC) for protocol handling from Embedded Algorithm Controller (EAC) for autonomous program/erase execution.

The EnduraFlex™ architecture allows runtime partitioning of memory into high-endurance (≥2.56M P/E cycles) and long-retention (25-year data hold) zones. Safety features include interface CRC, data integrity CRC, SafeBoot initialization reporting, and sector erase status tracking - all required for ASIL-B functional safety compliance in automotive ECUs.

Key Specifications

Density	1 Gb (128 MB) main array with 1024-byte OTP secure silicon region
Interface	Octal xSPI (8D-8D-8D DDR) up to 332 MBps; also supports legacy SPI at 20.75 MBps
Voltage Range	2.7–3.6 V core/I/O (HL-T grade); compatible with automotive 3.3-V rail systems
Endurance	2,560,000 program-erase cycles for main array; 300,000 cycles for 4 KB sectors
Data Retention	Minimum 25 years at 125 °C junction temperature per JEDEC JESD22-A117
Temperature Grade	AEC-Q100 Grade 1: −40 °C to +125 °C ambient operating range

Pinout & Package

Package: 24-ball BGA, 8 × 8 mm, 1.0-mm pitch, halogen-free, lead-free (RoHS compliant).

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select	Active-low enable signal; initiates all transactions and places outputs in high-Z when deasserted
CK	Serial Clock	Rising-edge–latched SDR; both-edge–latched DDR; defines timing for command/address/data transfer
DQ[7:0]	Bidirectional Data Bus	Octal I/O for x8 commands/addresses/data; SI/SO in legacy SPI mode
DS	Data Strobe Output	Synchronized toggle during reads to simplify high-speed data capture in DDR/SDR modes
RESET#	Hardware Reset	Optional active-low reset with internal weak pull-up; returns device to array read state on release
INT#	Open-Drain Interrupt	Signals completion of embedded operations (program/erase) or ECC error detection
VCC / VCCQ	Power Supplies	VCC = core logic (2.7–3.6 V); VCCQ = I/O drivers (same voltage, isolated for noise immunity)
VSS / VSSQ	Ground Returns	VSS = core ground; VSSQ = I/O ground; separate planes reduce switching noise coupling

Key Features

Feature	Design Value
EnduraFlex™ Partitioning	Enables independent configuration of memory regions for ≥1M-cycle endurance or 25-year retention without hardware change
SafeBoot Initialization	Detects corrupted configuration registers and recovers to known-good state without host intervention
SECDED ECC	Corrects single-bit errors and detects double-bit errors in real time during read operations across full memory array
Interface CRC	End-to-end checksum validation on all command/address/data transfers to prevent bus corruption-induced miswrites
AutoBoot Mode	Permits immediate memory access after power-on without requiring host-initiated configuration sequence

Applications

Automotive ADAS ECU Boot Storage

Industrial PLC Firmware Repository

Use Scenario: Holds field-upgradable control logic and motion profile tables in programmable logic controllers deployed in factory automation.

IC Role / Device Role / Timing Role: High-reliability firmware storage with 300K-cycle endurance for 4 KB parameter sectors and 25-year data retention at 85 °C.

Use Value: Eliminates need for external backup batteries or supercapacitors by guaranteeing data integrity over full product lifecycle without refresh.

Avionics Display System Code Memory

Medical Imaging Device Configuration Store

Use Scenario: Stores certified display rendering firmware and font assets in DO-178C Level A flight deck displays.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S28HL01GTFAHM033	Same density/package but HS-T (1.8 V); lower standby current (0.0013 mA vs. 0.0022 mA)	Targeted at low-power battery-backed systems; not rated for 125 °C operation	Select when core voltage is fixed at 1.8 V and thermal margin is <105 °C
MX66UM1G45GXDIO	Micron 1Gb Octal NAND with internal ECC; no ASIL-B certification; different command set	Lacks SafeBoot, interface CRC, and EnduraFlex; requires host-managed wear leveling	Choose only for cost-sensitive non-safety applications where NAND's higher density efficiency outweighs safety overhead

Compared with S28HL01GTFPBHM033, the HS-T variant trades automotive temperature range for lower power, while the Micron NAND alternative sacrifices functional safety compliance and autonomous error handling for raw density and cost - making it unsuitable for ASIL-B systems without extensive host-layer mitigation.

FAQ

Is S28HL01GTFPBHM033 pin-compatible with earlier Semper Flash devices like S28HL512T?

Yes - it shares the same 24-ball 8×8 mm BGA footprint and signal mapping as other S28HLx series devices. The pinout (CS#, CK, DQ[7:0], DS, RESET#, INT#, VCC/VCCQ, VSS/VSSQ) is identical across densities. No PCB redesign is needed when upgrading from 512 Mb to 1 Gb within the HL-T family.

Does this device support both Octal DDR and legacy SPI on the same physical pins?

Yes - DQ[7:0] operate as bidirectional octal data lines in xSPI mode and revert to SI/SO/DQ2–DQ7 in legacy SPI mode. Mode selection is determined by initial command sequence after power-on or reset; no hardware strapping is required. Both interfaces share CS#, CK, and VCC/VSS rails.

What is the purpose of the DNU pins in the 24-ball BGA package?

DNU (Do Not Use) pins - located at positions A1, A2, B1, B5, C1, D1, and E5 - are unconnected die pads with no internal bonding. They must remain floating or grounded per layout guidelines; routing traces or applying solder paste risks shorting to adjacent balls or inducing mechanical stress during reflow. Cypress explicitly prohibits their use for any signal or power function.

How does the EnduraFlex™ architecture affect firmware update procedures?

EnduraFlex™ allows dynamic partitioning of memory into endurance-optimized and retention-optimized zones via SFDP-defined registers. Firmware updates targeting frequently rewritten parameters (e.g., calibration tables) can be directed to 4 KB sectors with 300K-cycle rating, while boot code remains in 256 KB sectors rated for 2.56M cycles - all managed transparently by the host driver without changing flash translation layer logic.
