Detailed Description

4 Mbit (512 KB) SPI NOR Flash memory designed for code and data storage in embedded systems. Standard SPI interface, 3 V operation, 256-byte page programming, sector/block erase, hardware write-protect, deep power-down, and long data retention. Optimized for fast boot code and reliable non-volatile storage across a wide temperature range.

Key Features

Density: 4 Mbit (512 KB)

Interface: SPI (single I/O), standard command set

Supply voltage: typically 2.7–3.6 V (3 V class)

Max clock frequency: high-speed SPI (consult datasheet for exact MHz rating)

Page size: 256 bytes

Erase architecture: sectors/blocks (typical sector size 64 KB)

Hardware pins: WP# (write protect), HOLD#, CS#, CLK, DI (MOSI), DO (MISO)

Status register with write protection bits

Deep power-down and standby modes for low power

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

Data retention commonly 20+ years; program/erase endurance typically up to 100k cycles per sector (refer to datasheet for precise values)

JEDEC-compatible pinout for 8‑pin packages

RoHS compliant, Pb-free

Key Advantages

Simple, industry-standard SPI for easy MCU/SoC integration

Reliable NOR architecture for execute-in-place (XIP) and fast random reads

Low power in standby and deep-sleep modes

Robust write-protect options to safeguard critical code

Mature ecosystem with broad cross-vendor compatibility

Small 8‑pin footprint reduces PCB area and BOM cost

Packaging

Type: 8-pin IC package; tape-and-reel shipment (suffix indicates T for tape; PB denotes Pb-free)

Material: Molded epoxy package with copper leadframe; RoHS-compliant plating

Size (typical by variant):

- SOIC-8 narrow (JEDEC MS-012): approx. 4.9 x 3.9 mm body, 1.27 mm pin pitch

- VFQFPN/MLF-8: compact 5 x 6 mm or similar footprint (check the datasheet for exact VMN6 dimensions)

Pin configuration (typical for SPI NOR):

1 CS# (Chip Select), 2 DO (MISO), 3 WP#, 4 GND, 5 DI (MOSI), 6 CLK, 7 HOLD#, 8 VCC

Thermal characteristics: ThetaJA typically in the 80–120 °C/W range depending on package and PCB; continuous operation from -40 to +85°C (consult datasheet for exact limits)

Electrical properties (typical): 2.7–3.6 V VCC, low standby current, fast read, 256-byte page program, sector erase; exact timing and current draw per datasheet

Lifecycle

Status: Mature product; certain suffix options may be NRND or have limited availability depending on region. Check current stock and lead times.
