Detailed Description

1 Mbit (128 KB) DataFlash serial memory with SPI interface in SOP8 package. D-series architecture with page-based storage and dual SRAM buffers for fast writes and continuous reads. Industrial temperature grade, low-power operation, hardware write protection, and reset support. Suitable for embedded systems needing reliable non-volatile storage.

Key Features

1 Mbit density (approx. 128 KB usable)

SPI interface, up to about 20 MHz

Page-based architecture with user-configurable binary page size (typical default 264 bytes, can be set to 256 bytes)

Two internal SRAM buffers for seamless data streaming (buffered write/read)

Continuous read modes for high throughput

Auto page erase/program with built-in timing

Hardware Write Protect (WP#) and Reset (RESET#) pins

Deep power-down and standby modes for low energy use

Endurance typically 100k program/erase cycles per page

Data retention commonly 20 years

Industrial operating temperature range (about -40°C to +85°C)

Key Advantages

Simple SPI interface reduces MCU resource use

Dual-buffer design speeds logging and firmware updates

Flexible page size eases file system and data structure alignment

Low power saves battery in portable and IoT devices

Robust endurance and retention for long-term reliability

Small SOP8 footprint simplifies PCB layout and lowers BOM cost

Packaging

Type: SOP8 (SOIC-8, narrow body)

Package/Case code: 611 (SOP8)

Material: Molded epoxy, lead-free plating

Approximate size: 4.9 mm x 3.9 mm x 1.5 mm body, 1.27 mm lead pitch

Pin configuration:

1 CS# (Chip Select)

2 SO (Serial Data Out, MISO)

3 WP# (Write Protect)

4 GND

5 SI (Serial Data In, MOSI)

6 SCK (Serial Clock)

7 RESET#

8 VCC

Thermal characteristics (typical for SOP8 on standard PCB): ThetaJA around 100–130 °C/W; Max junction temperature about 125 °C

Electrical properties (typical):

- Supply voltage: about 2.5 V to 3.6 V

- Max SPI clock: about 20 MHz

- Active read/program current: a few mA (typical ~4 mA)

- Standby current: low hundreds of µA (typical ~0.15 mA)

- Deep power-down current: a few µA (typical <5 µA)

- Operating temperature: -40°C to +85°C

Lifecycle

Status: Availability can be limited for some AT45DB0xxD variants. Some D-series DataFlash parts have moved to NRND/EOL in certain regions.

Recommended action: Check current stock and lead time with Y-IC. If this exact part is constrained, consider equivalent or alternative models below.

Equivalent or alternative models (capacity and interface similar; note that standard SPI Flash uses different command sets than DataFlash, so firmware changes may be needed):

- Microchip AT25DF011A (1 Mbit SPI Flash)

- Winbond W25X10CLSNIG (1 Mbit SPI Flash)

- Macronix MX25V1035 (1 Mbit SPI Flash)

- GigaDevice GD25Q10 (1 Mbit SPI Flash)

- ROHM BR25L010 series (1 Mbit SPI Flash)
