AO3402L datasheet

 

Description

The AO3402L uses advanced trench technology to provide excellent R DS(ON), low gate charge and operation with gate voltages as low as 2.5V. This device is suitable for use as a load switch or in PWM applications. This is a logic-level N-channel MOSFET in a compact SOT-23 package, designed for low-voltage switching applications with a 30V drain-source rating. It utilizes advanced trench technology to achieve low RDS(ON), fast switching performance, and efficient operation even at low gate drive voltages. This device is widely used in load switching, DC-DC converters, and PWM-controlled power circuits.

Description

The Microchip Technology Inc. 25AA080, 25LC080, 25C080 (25XX080) are 8 Kbit Serial Electrically Erasable PROMs. The memory is accessed via a simple Serial Peripheral Interface™ (SPI™) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input.

Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of chip select, allowing the host to service higher priority interrupts.

It is designed for low-power, non-volatile data storage in embedded systems, offering byte-level access with page-write capability and self-timed erase/write cycles. The device includes a HOLD function to pause communication without resetting the internal state, making it suitable for interrupt-driven systems.

Features

  • 8 Kbit EEPROM (1024 × 8-bit organization)
  • SPI-compatible interface (SCK, SI, SO, CS)
  • Low-power CMOS operation
  • Write current: ≤ 3 mA
  • Read current: ~500 µA typical
  • Standby current: ~500 nA typical
  • 16-byte page write capability
  • Self-timed write and erase cycle (max 5 ms)
  • HOLD pin for pausing serial communication
  • Supports sequential read and write operations

Pin Configuration

25AA080 datasheet

Functional Description

  • Data is accessed via SPI using standard commands (READ, WRITE, WREN, WRDI, RDSR, WRSR)
  • Page write allows up to 16 bytes to be written in a single operation
  • Internal write cycle automatically handles erase-before-write
  • Status register indicates write-in-progress (WIP) and write enable latch (WEL)
  • HOLD pin allows communication pause without resetting the SPI session

Design Notes

  • Ensure CS is properly controlled to frame SPI transactions
  • Respect page boundaries during write operations to avoid data wraparound
  • Use WP pin for hardware-level write protection if needed
  • Add proper decoupling capacitor (e.g., 0.1 µF) close to VCC pin
  • Consider write endurance and cycle limits for frequent updates

How to Choose This Part

  • Select for low-density non-volatile storage with SPI interface
  • Ideal when low power consumption is critical
  • Suitable for applications requiring small page writes
  • Choose higher-density variants (e.g., 25AA160, 25AA320) if more memory is needed

Typical Applications

  • Configuration and calibration data storage
  • Embedded systems non-volatile memory
  • Industrial control parameter storage
  • Consumer electronics settings retention

Alternative / Equivalent Products

  • 25LC080 (wider voltage range variant)
  • AT25080 (Microchip/Atmel equivalent)
  • M95080 (STMicroelectronics SPI EEPROM)
  • CAT25080 (ON Semiconductor equivalent)
