AT25040B-SSHL-T 是由美国微芯科技(Microchip Technology Inc.)推出的一款高性能非易失性存储器,属于 EEPROM(电可擦可编程只读存储器)系列。其主要特点是小巧、灵活且易于集成,广泛应用于需要可靠数据存储的各种电子设备和系统中。
AT25040B-SSHL-T 的存储容量为 4 Kbit(即 512 x 8 位),通过 SPI(Serial Peripheral Interface)接口进行数据传输,支持的最大时钟频率为 20 MHz。这使得其在数据读写过程中能够实现快速响应与高效性能。
该器件的工作电压范围为 1.8V 到 5.5V,使其能够灵活适应多样的电源环境。这一电压范围确保了在低电压下也能保持高效的读写性能,适合用于便携式和电池供电的应用。
非易失性存储:AT25040B-SSHL-T 的数据存储特性使其在电源断电情况下依然能够保持数据完整性,适用于存储配置参数、设备设置及其他关键数据。
快速写入周期:在此器件中,数据的写入周期时间为 5ms,这为需要频繁更新存储内容的应用提供了便捷。同时,由于其支持页写入模式,用户可以在一次操作中写入多个字节的数据,从而提升写入效率。
温度范围:该器件适用于广泛的工作温度范围,从 -40°C 到 +85°C 的温度范围使其在严苛的工业环境及户外应用中也能够保持稳定的性能。
AT25040B-SSHL-T 采用 8-SOIC 封装(尺寸为 0.154" x 3.90mm),这种表面贴装型设计不仅节省空间,还方便在现代电子设备中集成。8-SOIC 封装的轻巧特性使其成为需要高密度布局的电路板的理想选择。
AT25040B-SSHL-T 的应用场景相当广泛,几乎涵盖了所有需要数据存储的领域,包括但不限于:
消费电子:例如家庭电器、便携式音响和其他智能设备,能够存储用户偏好设置、播放记录等。
汽车电子:在现代汽车中,AT25040B-SSHL-T 可以用于存储车辆的故障诊断信息、导航设置等关键数据。
工业自动化:在自动化设备中,该器件能够保存设备的配置参数和历史数据,使设备在重启后能够恢复至正常工作状态。
医疗设备:用于存储病人信息、设备校准参数等,确保医疗设备在不同环境条件下均能实现可靠的数据存储。
综上所述,AT25040B-SSHL-T 作为微芯科技推出的一款功能强大的 EEPROM 存储器,凭借其高性能、广泛的工作电压范围、适应极端温度的能力以及小巧的表面贴装设计,无疑将成为各种电子产品中理想的选择。它的可靠性和灵活性使其完美适应多种应用需求,能够为设计工程师和产品开发者提供更高效的解决方案。无论是用于简单的消费电子产品还是复杂的工业设备,AT25040B-SSHL-T 都能如用户所愿,确保重要数据的安全和完整性。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
