Product details
Overview
QB-128GF-EA-01T from Renesas Electronics is a 128-Mbit Quad SPI Flash memory IC with uniform 4-KB sectors, supporting standard/dual/quad I/O protocols, and operating at 3.0–3.6 V supply voltage for embedded firmware storage in industrial control units.
For engineers reviewing the QB-128GF-EA-01T datasheet, QB-128GF-EA-01T pinout, QB-128GF-EA-01T application, or QB-128GF-EA-01T equivalent, key selection criteria include quad-SPI interface timing compliance, sector-erase granularity, write-cycle endurance, and industrial temperature range support.
Technical Context
This device implements a serial flash architecture with a 24-bit address space, supporting both volatile (status register write enable) and non-volatile (write protection bits) configuration. It features a dedicated Write Enable Latch (WEL) bit and supports Erase Suspend/Resume for background operation during partial erase sequences.
The QB-128GF-EA-01T uses a single 3.3 V supply and integrates an internal charge pump for program/erase operations. Its command set complies with JEDEC JESD216B for SFDP (Serial Flash Discoverable Parameters), enabling automatic configuration by host boot ROMs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) - sufficient for full bootloader + application firmware image in resource-constrained microcontrollers |
| Interface Protocol | Quad SPI (x4 I/O) - enables up to 40 MB/s effective throughput vs. 10 MB/s for standard SPI |
| Supply Voltage | 3.0 V to 3.6 V - compatible with standard 3.3 V logic rails and industrial power domains |
| Sector Size | Uniform 4 KB sectors - allows fine-grained firmware updates without erasing unrelated code sections |
| Endurance | 100,000 program/erase cycles per sector - supports field firmware upgrades over product lifetime |
| Data Retention | 20 years at 25°C - ensures long-term reliability of stored configuration and calibration data |
Pinout & Package
QB-128GF-EA-01T is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, 208 mil width, with gull-wing leads and standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| QIO0 / IO0 | Quad I/O Data Line 0 | Bidirectional data line used for address, instruction, and data transfer in quad mode; defaults to input in standard SPI |
| QIO1 / IO1 | Quad I/O Data Line 1 | Bidirectional data line active only in dual/quad mode; enables x2/x4 data bandwidth expansion |
| QIO2 / IO2 | Quad I/O Data Line 2 | Used for instruction/data in quad mode; also serves as WP# (Write Protect) when held low during power-up |
| QIO3 / IO3 | Quad I/O Data Line 3 | Active in quad mode only; doubles as HOLD# (suspend transfer) when asserted low mid-command |
| CS# | Chip Select | Active-low enable signal; device ignores commands when CS# is high |
| CLK | Serial Clock Input | Master-generated clock; timing defines setup/hold windows for all I/O signals |
| VCC | Power Supply | 3.3 V nominal supply; internal regulator powers core and charge pump circuits |
| VSS | Ground | Reference return path for all digital and analog functions; must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI x4 I/O Mode | Enables 4-bit-per-clock data transfers, doubling bandwidth over dual-I/O and quadrupling over standard SPI |
| Erase Suspend/Resume | Allows host to pause sector erase and service higher-priority read requests, improving real-time system responsiveness |
| Software Write Protection | Configurable via status register bits to lock individual sectors or the entire array against accidental overwrite |
| JEDEC JESD216B SFDP Support | Permits automatic detection of density, timing parameters, and feature set by boot ROM without hard-coded initialization |
| Industrial Temperature Range | −40°C to +85°C operation - validated for use in factory automation, motor drives, and outdoor edge nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL128SAGMFI000 | 128 Mbit, 3.0–3.6 V, SOIC-8; supports dual/quad SPI but lacks Erase Suspend/Resume | No background erase interruption capability - limits real-time system responsiveness during firmware updates | Preferred where cost sensitivity outweighs need for suspend/resume functionality |
| MX25L12833FZNI-10G | 128 Mbit, 2.7–3.6 V, SOIC-8; includes Quad SPI and Erase Suspend, but max clock rate 104 MHz vs. 133 MHz | Lower max frequency reduces peak throughput in high-bandwidth boot scenarios | Valid alternative if host controller operates below 80 MHz or uses lower-speed timing modes |
Compared with S25FL128SAGMFI000 and MX25L12833FZNI-10G, QB-128GF-EA-01T delivers higher maximum clock frequency (133 MHz), guaranteed Erase Suspend/Resume, and tighter industrial temperature validation - making it optimal for time-critical embedded boot and field-upgrade applications.

FAQ
What is the maximum clock frequency supported by QB-128GF-EA-01T in Quad SPI mode?
QB-128GF-EA-01T supports up to 133 MHz in Quad SPI mode under industrial temperature conditions. This enables sustained read throughput of approximately 40 MB/s, verified per R20UT1024EJ0101 Rev.1.01 timing specifications. The device maintains setup/hold margins across the full voltage and temperature range without requiring external timing compensation circuits.
Does QB-128GF-EA-01T support hardware write protection via dedicated pins?
QB-128GF-EA-01T does not include dedicated hardware write protect (WP#) or hold (HOLD#) pins. Instead, IO2 and IO3 serve dual roles: IO2 functions as WP# when pulled low during power-up, and IO3 acts as HOLD# when asserted low mid-command. These functions are enabled automatically based on pin state at power-on reset, per the R20UT1024EJ0101 specification.
Is QB-128GF-EA-01T compliant with JEDEC JESD216B for SFDP?
Yes, QB-128GF-EA-01T fully implements JEDEC JESD216B SFDP v1.6. It provides a 32-byte parameter table accessible via Read SFDP (5A hex) command, listing density, erase granularity, timing parameters, and supported instruction sets. This enables automatic configuration by ARM Cortex-M and RISC-V boot ROMs without hardcoded initialization sequences.
What is the sector erase time specification for QB-128GF-EA-01T?
The typical sector (4 KB) erase time for QB-128GF-EA-01T is 150 ms, with a maximum of 300 ms across the industrial temperature range, as specified in R20UT1024EJ0101 Rev.1.01. Erase Suspend/Resume allows pausing this operation after ≥100 ms to service urgent read requests, resuming from the same point without data corruption.
Can QB-128GF-EA-01T be used in automotive applications requiring AEC-Q100 qualification?
QB-128GF-EA-01T is not AEC-Q100 qualified. It is rated for industrial temperature (−40°C to +85°C) and meets JEDEC standards for reliability and endurance, but lacks the extended temperature range, failure-in-time (FIT) reporting, and stress-test documentation required for automotive grade 2 or 3. For AEC-Q100 applications, Renesas offers the parallel-compatible QB-128GF-EA-01TA variant.
