The EM91450BP is a microcontroller manufactured by ELAN Microelectronics. Similar to other EM91xxx series components, it likely served in various embedded applications. As indicated by the 'END - OF - LIFE' status, this part is no longer actively produced or supported by the manufacturer. This means information may be limited to existing legacy documentation and potentially archived online resources.

Applications:

• Remote control devices
• Low-power consumer electronics
• Simple industrial control systems
• Toys and educational devices
• Legacy embedded systems requiring replacement parts

Features:

• 8-bit microcontroller core
• On-chip ROM for program storage
• RAM for data manipulation and temporary storage
• Multiple programmable I/O pins for interfacing with external components
• Timers and counters for timing-related functions
• Interrupt handling capabilities for responding to external events

Benefits:

• Cost-effective solution for basic control applications
• Low power consumption, suitable for battery-operated devices
• Compact size for integration into small form-factor products
• Easy to program (using assembly language or C, depending on available tools)
• Reliable performance within specified operating conditions

Additional Details:

Specific technical specifications for the EM91450BP may include:

• Operating voltage: typically 3V to 5V
• Clock frequency: determined by an external crystal oscillator or internal RC oscillator
• Number of I/O pins: varies depending on the package type (DIP, SOP, etc.)
• Memory size: limited ROM and RAM capacity compared to modern microcontrollers
• Peripherals: may include UART, SPI, or other serial communication interfaces

Due to its end-of-life status, sourcing this part may be challenging, and direct support from ELAN Microelectronics is unlikely. Datasheets and application notes may be available through third-party websites or archived documentation repositories.
