ATTINY202-SSNR 是一款由美国微芯科技(Microchip Technology)公司生产的高性能微控制器(MCU),基于 AVR 架构,专为低功耗和高效能的嵌入式系统设计。该微控制器在多种应用场景中表现出色,尤其是在需要灵活的连接能力和高效数据处理的行业中。
ATTINY202-SSNR 配备了一个 8 位 AVR 核心处理器,其主频可达 20MHz。这使其适合执行复杂的控制任务,并处理多个 I/O 操作。8 位处理器架构在低功耗设备中非常受欢迎,因为它能够以较低电量消耗实现有效的性能,特别适合于电池供电的设备。
微控制器内部集成有 2KB 的闪存,用于程序存储,这在许多中小型应用中足够满足存储需求。此外,64 x 8 的 EEPROM 和 128 x 8 的 SRAM 提供了灵活的数据存储选项,用户可以根据需要进行数据持久存储和临时数据处理。EEPROM 的容量使得用户能够保存参数和配置数据,而 SRAM 更加适合运行时数据的处理。
ATTINY202-SSNR 提供了丰富的外设接口,包括 I²C、IrDA、LINbus、SPI 和 UART/USART。这种广泛的连接能力使得其在各类通信和信息传输领域具备极高的通用性。例如,I²C 可用于连接传感器和执行器,SPI 适合高速数据传输,而 UART 可用于串行通信。
此外,该微控制器内置的多种外设,如欠压检测/复位(POR)、脉宽调制(PWM)和看门狗定时器(WDT),为用户设计应用程序提供了极大的便利。欠压检测确保在电源电压下降到一定水平以下时,微控制器能够安全地复位,从而防止数据损坏。PWM 则常用于控制电机速度和亮度调节等应用。
ATTINY202-SSNR 采用 8-SOIC 封装,具有紧凑的尺寸(0.154",3.90mm 宽),这使得该微控制器非常适合嵌入式设计,尤其是在空间受限的环境中。此外,该微控制器的工作温度范围为 -40°C 至 105°C,表明其具备良好的环境适应能力,可在各种严苛的工业环境中稳定工作。
该产品的工作电压范围为 1.8V 至 5.5V,确保其在多个电压标准下的兼容性,也使其适用于低电压应用,从而有效降低能耗。ATTINY202-SSNR 特别适合于对功耗敏感的应用,如便携式设备、消费电子以及工业自动化设备。
ATTINY202-SSNR 适用于广泛的应用场景,包括但不限于简单的传感器数据采集、灯光控制、家居自动化、智能汽车电子、以及医疗设备。这种灵活性使得其成为设计师和开发者实现各种奇思妙想的理想选择。
总之,ATTINY202-SSNR 是一款具有强大功能和灵活性的微控制器,能够满足当今数字设备对高效能、低功耗和广泛连接的需求。无论是在消费电子、工业控制、还是物联网应用中,ATTINY202-SSNR 都能够为设计师提供强有力的支持,使其可以创造出更加智能和便捷的产品。
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.
