IA8044R0146-PLC44I-01 is listed in the Application Specific Microcontrollers range at ChipApex. The manufacturer field lists Analog Devices Inc.. Its product description is IC SDLC COMM CTLR 44PLCC. Review the specifications below when checking this part for your BOM.
The IA8044R0146-PLC44I-01 is an application-specific microcontroller manufactured by Analog Devices Inc. It is designed for serial data link control (SDLC) communication tasks. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 5 MHz. It features an 8-bit data bus width and includes 112 bytes of data RAM. The component is housed in a PLCC-44 package, suitable for surface mount installation. It functions within a temperature range of -40°C to +85°C.
This component is classified as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary distributors or existing stock. Verify part authenticity and condition carefully when purchasing from non-direct channels due to discontinuation status.
Select this part only if legacy SDLC compatibility is required. Consider modern alternatives if new designs are feasible, as the component is discontinued. Ensure system requirements match the 8-bit architecture and 5 MHz speed limitations before procurement.
The IA8044 series represents specialized communication controllers from Analog Devices. This specific model targets SDLC applications, differing from general-purpose microprocessors. It belongs to a family of components designed for dedicated protocol handling rather than flexible computing tasks.
No direct public substitute part numbers are confirmed for this obsolete component. Engineers should evaluate generic SDLC controllers or updated microcontrollers with software-defined protocol support for replacement strategies.
