Overview of STMicroelectronics M48T86PC1 The STMicroelectronics M48T86PC1 is a specialized integrated circuit (IC) used primarily as a backup memory solution. It combines non-volatile SRAM with a battery backup system, allowing it to retain data even when power is lost. This device is part of the M48 series of real-time clock (RTC) and SRAM components, specifically designed for applications where data integrity is critical in the event of a power failure. Functions - Non-Volatile SRAM: It provides memory storage that retains data without needing continuous power. - Real-Time Clock (RTC): It includes a real-time clock function, facilitating timekeeping applications. - Battery Back-Up: The built-in battery keeps the SRAM data intact when the primary power source is lost. - Low Power Consumption: Designed for low power operation, making it suitable for battery-operated devices. Applications - Datasheets: For devices that require low power memory retention, such as embedded systems and IoT devices. - Computing Devices: Useful in situations where data must be preserved between sessions, like BIOS settings in PCs. - Consumer Electronics: Found in devices like digital cameras and smart appliances needing persistent settings or logs. - Industrial Applications: Suitable for systems that need to maintain real-time data tracking and logging, like manufacturing equipment. Alternative Components 1. M48T35: Similar non-volatile SRAM product with a different capacity for less demanding applications. 2. Buzzer-Controlled RTCs: Provides timekeeping functionality but may lack backup memory features. 3. EEPROMs: These are also non-volatile memory devices, but generally have slower write speeds compared to SRAM. 4. Flash Memory: Non-volatile and useful in similar applications, but often requires more complex management for write cycles. Embedded Modules - M48T86PC1 Modules: Some manufacturers may offer development boards or integrated modules featuring the M48T86PC1 for prototyping and testing. - RTC Modules: Other RTC modules might include similar features but vary in memory capabilities or battery life. - Microcontroller Development Boards: Boards that have integrated RTC and SRAM capabilities might embed such components to enhance functionality.
