Product details
Overview
AT25DN011-SSHFGP-B from Renesas Electronics is a 1-Mbit SPI serial flash memory IC supporting dual-output read, 104 MHz max clock frequency, 6 ns clock-to-output delay, and flexible erase architecture (256-byte page / 4-kByte & 32-kByte blocks). It operates from 2.3 V to 3.6 V and is used for code shadowing and embedded data storage in resource-constrained microcontroller systems.
For engineers reviewing the AT25DN011-SSHFGP-B datasheet, AT25DN011-SSHFGP-B pinout, AT25DN011-SSHFGP-B application, or AT25DN011-SSHFGP-B equivalent, key selection criteria include dual-read throughput, ultra-deep power-down current (350 nA), OTP security register support, hardware write protection via WP pin, and industrial temperature range compliance.
Technical Context
The AT25DN011-SSHFGP-B implements a standard SPI interface with full compatibility for Modes 0 and 3, using rising-edge input sampling and falling-edge output timing. Its dual-output read mode repurposes the SI pin as I/O0 alongside SO (I/O1) to deliver two bits per SCK cycle, doubling effective read bandwidth versus standard single-output reads.
Internally, the device features a segmented memory array with uniform 4-kByte and 32-kByte erase blocks plus 256-byte page erase capability - enabling efficient co-location of code modules and data segments without cross-contamination during updates. Protection is enforced via both software-configurable status register bits and hardware-controlled WP pin locking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 bytes), sufficient for boot code + firmware + configuration data in compact MCU designs. |
| Supply Voltage Range | 2.3 V – 3.6 V - enables direct interfacing with 2.5 V and 3.3 V logic domains without level shifting. |
| Max Clock Frequency | 104 MHz - supports high-speed read operations up to 13 MB/s in dual-output mode (2 bits/cycle × 104 MHz). |
| Read Latency (tV) | 6 ns - ensures minimal wait states when fetching instructions from flash into CPU cache or RAM. |
| Erase Granularity | 256-byte page / 4-kByte block / 32-kByte block - allows precise firmware patching and field-upgradable parameter storage. |
| Power-Down Current | 350 nA ultra-deep power-down - critical for battery-powered IoT endpoints requiring multi-year shelf life. |
| Endurance & Retention | 100,000 program/erase cycles and 20-year data retention - validated for long-life industrial control and automotive telematics. |
Pinout & Package
AT25DN011-SSHFGP-B is packaged in an 8-lead SOIC (150-mil) with standard JEDEC footprint and pinout. This package supports reflow soldering and is compatible with automated PCB assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must transition low-to-high to complete commands and enter standby mode after self-timed operations. |
| SCK | Serial Clock | Master-generated clock; rising edge latches input (SI), falling edge clocks output (SO/I/O0); supports up to 104 MHz. |
| SI (I/O0) | Serial Input / Dual-Output Data 0 | Input for commands/addresses/data; becomes output (I/O0) during dual-output read to deliver LSB-aligned bitstream with SO. |
| SO (I/O1) | Serial Output / Dual-Output Data 1 | Primary output for standard reads; remains active (I/O1) during dual-output read to deliver MSB-aligned bitstream with SI. |
| WP | Write Protect | Hardware lock control: low assertion disables all write/erase commands - prevents accidental firmware corruption during power transients. |
| HOLD | Communication Hold | Pauses ongoing SPI transfers without deselecting device; requires CS asserted and SCK low to activate - useful for interrupt servicing. |
| VCC | Power Supply | Single 2.3–3.6 V supply; no auxiliary voltage required for programming or erasing - simplifies power design. |
| GND | Ground Reference | System ground return path; decoupling capacitor placement near this pin is mandatory for stable high-frequency operation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Output Read Mode | Enables 2-bit-per-cycle data transfer using SI and SO simultaneously - doubles read bandwidth over standard SPI without increasing clock rate. |
| Flexible Erase Architecture | Supports 256-byte page, 4-kByte block, 32-kByte block, and full-chip erase - minimizes wasted space and enables atomic firmware updates. |
| 128-byte OTP Security Register | One-time programmable area for device serialization, ESN storage, or cryptographic key binding - immune to field reprogramming. |
| Ultra-Deep Power-Down | Reduces current draw to 350 nA typical - extends battery life in always-on sensor nodes and remote monitoring devices. |
| Hardware Write Protection | WP pin provides physical lockout of all write/erase commands - eliminates risk of corruption during brown-out or noise events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q80DVSSIG | 8-Mbit density, same 2.3–3.6 V supply, but lacks ultra-deep power-down (1 µA vs. 350 nA) and OTP register. | Better suited for higher-capacity boot storage where ultra-low sleep current is secondary. | Select if >1 Mbit capacity is needed and deep-sleep current is not critical. |
| Micron MT25QL01GBBB8E12-0SIT | 1-Gbit density, quad-SPI interface, 133 MHz max clock, but requires 1.7–2.0 V or 2.7–3.6 V dual supply - no 2.3 V minimum support. | Targeted at high-performance applications needing quad-I/O bandwidth and larger code images. | Select only if quad-SPI throughput and >1 Mbit capacity outweigh single-supply simplicity and ultra-low-power needs. |
Compared with W25Q80DVSSIG and MT25QL01GBBB8E12-0SIT, the AT25DN011-SSHFGP-B delivers optimal balance of ultra-low power (350 nA), industrial temperature resilience, and fine-grained erase control - making it uniquely suitable for compact, battery-sensitive, and safety-critical embedded systems where 1 Mbit suffices.

FAQ
What is the maximum operating frequency supported by the AT25DN011-SSHFGP-B?
The AT25DN011-SSHFGP-B supports a maximum operating frequency of 104 MHz for all command types including read, program, and erase operations. This enables high-throughput dual-output read performance up to 13 MB/s. The device maintains timing integrity across its full industrial temperature range (-40°C to +85°C) and 2.3–3.6 V supply range without derating.
Does the AT25DN011-SSHFGP-B support dual-output read mode, and how does it affect pin usage?
Yes, the AT25DN011-SSHFGP-B supports dual-output read mode using opcode 3Bh. In this mode, the SI pin functions as I/O0 (output) alongside SO as I/O1 (output), delivering two bits per SCK falling edge. This requires no additional pins but mandates proper timing alignment between SI and SO outputs - confirmed in Figure 9 and Section 5.1 of the datasheet.
What erase options are available on the AT25DN011-SSHFGP-B, and what are their typical durations?
The AT25DN011-SSHFGP-B supports four erase options: 256-byte page erase (1.25 ms typical), 4-kByte block erase (35 ms typical), 32-kByte block erase (250 ms typical), and full chip erase. These granular options allow targeted updates without disturbing adjacent code or data - critical for field-upgradable firmware and parameter storage in safety-certified systems.
How does the hardware write protection (WP) pin function on the AT25DN011-SSHFGP-B?
The WP pin on the AT25DN011-SSHFGP-B provides hardware-enforced lockout of all write, program, and erase commands when asserted low. It works independently of software status register settings and remains active even during power transitions. The pin is internally pulled high, so leaving it unconnected defaults to unprotected mode - external pull-up to VCC is recommended unless protection is actively used.
What is the purpose and capacity of the OTP security register in the AT25DN011-SSHFGP-B?
The AT25DN011-SSHFGP-B includes a 128-byte One-Time Programmable (OTP) security register accessible via opcodes 9Bh (program) and 77h (read). Once programmed, contents cannot be altered - making it ideal for storing immutable device identifiers, electronic serial numbers (ESN), or cryptographic keys. This register resides outside main memory and is protected from accidental overwrite by dedicated command protocols.
