GD25LE32DLIGR

A: The GD25LE32DLIGR is designed to provide high‑speed data throughput while consuming minimal power, making it ideal for battery‑powered and portable systems. The table below summarises its core specifications, drawn directly from manufacturer data and multiple distributor sources: Specification Value Memory Density 32 Mbit (4 Mbyte) Memory Organization 4M × 8 bits Memory Technology FLASH – NOR Memory Interface SPI, Dual I/O, Quad I/O, QPI Max Clock Frequency 120 MHz (Single, Dual and Quad I/O) Equivalent Data Rate Up to 480 Mbits/s (120 MHz × 4‑bit in Quad I/O mode) Supply Voltage (VCC) 1.65V to 2.0V (1.8V nominal) Page Size 256 bytes per programmable page Page Program Time (tPP) 0.3 ms (typical) Write Cycle Time – Word, Page 2.4 ms (max) Sector / Block Erase 4KB sector erase, 32/64KB block erase Chip Erase Time (tCE) 15 s (typical) Active Read Current 4 mA (typical) Power‑down (Standby) Current 0.5 μA (typical), 30 μA (max) Operating Temperature (Industrial) –40°C to +85°C (TA) Extended Temperature Option –40°C to +105°C / –40°C to +125°C available Write Endurance 100,000 cycles (minimum) Data Retention 20 years (minimum) Package Type 21‑pad WLCSP (21‑XFBGA, WLSCP) RoHS Status RoHS3 compliant (Lead‑free, Halogen‑free) Moisture Sensitivity Level (MSL) 1 (Unlimited) ECCN 3A991B1A Additional features include: Software RESET – Provides a software command to reset the device to a known state without power cycling. Security Registers with OTP Locks – Dedicated One‑Time Programmable registers for secure storage of device‑unique information (e.g., serial numbers, encryption keys). Suspend – Supports Erase/Program Suspend & Resume, allowing the host to interrupt a long erase or program operation to execute higher‑priority tasks. Unique ID (UID) – Factory‑programmed 64‑bit Unique ID for each device, enabling device traceability and authentication. HOLD# Pin – Allows the host to pause an ongoing serial communication without resetting the ongoing instruction, useful in multi‑device SPI bus systems where the bus may need to be temporarily shared for higher‑priority tasks. Write Protect (WP#) – Provides hardware and software write protection for selected sectors or the entire memory array, preventing accidental data corruption. Block Protection (BP4–BP0) – Software‑configurable bits that define protected memory areas (e.g., top, bottom, or any combination of sectors). Status Register Protection (SRP1, SRP0) – Configurable protection of the status register (Software Protected, Hardware Protected, Power Supply Lock‑Down or One‑Time Programmable).

A: The GD25LE32DLIGR uses a standard 4‑wire Serial Peripheral Interface (SPI) bus, supporting SPI Mode 0 and Mode 3 for maximum compatibility with a wide range of microcontrollers and SoCs. Beyond standard SPI, the device offers multiple high‑performance interface options: Single I/O (Standard SPI) – Uses separate SI (data in) and SO (data out) pins for 1‑bit data transfers per clock cycle. Dual I/O (Dual SPI) – Uses IO0 and IO1 pins as bidirectional I/O lines, transferring 2 bits of data per clock cycle, effectively doubling the data throughput compared to standard SPI without increasing the clock frequency. Quad I/O (Quad SPI) – Uses all four I/O pins (IO0, IO1, IO2, IO3) for simultaneous data transfer, delivering up to four bits per clock cycle – equivalent to a 480 MHz effective data rate (120 MHz × 4). This high throughput enables true Execute‑In‑Place (XIP) operation, allowing the host to execute code directly from the flash memory without needing to copy it to RAM first. QPI (Quad Peripheral Interface) – Also supported, operating entirely in 4‑bit mode for reduced command overhead and improved throughput. The device also features a Continuous Read Mode with configurable wrap (8/16/32/64 bytes) to optimise sequential read operations in XIP applications.

A: The GD25LE32DLIGR is specifically engineered for ultra‑low power operation and long‑term reliability, making it ideal for battery‑powered wearables, IoT sensors, and portable medical devices. The table below outlines its key power and reliability specifications: Parameter Specification Power‑down (Standby) Current 0.5 μA (typical), 30 μA (max) Active Read Current 4 mA (typical) Page Program Current 6 mA (typical) Page Program Time 0.3 ms (typical) Sector Erase Time (4KB) 45 ms (typical) Block Erase Time (32KB / 64KB) 120 ms / 150 ms (typical) Chip Erase Time 15 s (typical) Write Endurance 100,000 program/erase cycles (minimum) Data Retention 20 years (minimum) ESD Protection (HBM) ±4 kV The GD25LE family is designed with greatly reduced power consumption in standby and hibernation modes compared to general‑purpose SPI NOR Flash families, achieving the industry’s lowest Quad SPI NOR Flash power consumption. This makes the GD25LE32DLIGR especially well‑suited for applications requiring long battery life, such as true wireless earbuds, fitness trackers, smartwatches, and IoT edge nodes where every microampere of standby current matters.

A: Thanks to its 32Mb capacity, ultra‑low standby current (0.5 μA typical), high‑speed Quad SPI interface, industrial temperature range (–40°C to +85°C), and compact WLCSP‑21 package, the GD25LE32DLIGR is well‑suited for a broad range of power‑sensitive and space‑constrained embedded applications. Typical use cases include: Wearable devices – Smartwatches, fitness trackers, hearables, and true wireless earbuds. Internet of Things (IoT) edge devices – Sensor nodes, wireless modules, and remote monitoring systems. Industrial control systems – PLCs, HMIs, data loggers, and factory automation equipment. Consumer electronics – Smart home appliances, digital cameras, MP3 players, and game controllers. Medical devices – Portable diagnostic instruments, patient monitors, and wearable health trackers. Networking and communication equipment – Routers, switches, and wireless access points. Automotive systems – Infotainment systems, dashcams, and telematics units (with extended temperature options).
