Overview
The COM8017LJP is a CMOS Serial I/O Controller manufactured by SMSC, housed in a 28-pin Plastic Dual In-Line Package (PDIP). It operates at a nominal supply voltage of 5 V and supports standard TTL/CMOS logic levels. The device integrates UART functionality with FIFO buffers to manage serial data transmission and reception efficiently. Designed for commercial temperature ranges, it provides reliable serial communication interfaces for embedded systems requiring robust asynchronous data handling capabilities.
Feature Summary
- Integrated UART controller with FIFO buffers for efficient serial data management
- Compatible with standard TTL/CMOS logic voltage levels
- Supports multiple baud rates and programmable configuration options
Applications
- Industrial control systems requiring serial communication
- Embedded computer peripheral interfacing
- Data acquisition systems with serial input/output needs
Procurement Notes
Verify the specific suffix 'LJP' against official SMSC documentation to confirm package type and temperature grade. Ensure compatibility with existing 5V logic designs. Check for RoHS compliance status as older SMSC parts may not meet current environmental directives. Confirm pinout alignment with system PCB layout requirements before procurement.
Selection Notes
Select this component when a dedicated serial I/O controller with FIFO capability is required in a through-hole package. Compare against newer integrated solutions if board space is limited. Verify that the commercial temperature range meets the operational environment requirements. Consider availability and lifecycle status given the age of the SMSC product line.
Part Context
This part belongs to the SMSC COM801x family of serial I/O controllers. These devices were widely used in legacy PC architectures and industrial automation. SMSC was later acquired by Microchip Technology, which continues to support some of these legacy interfaces. The COM8017 variant specifically offers enhanced features compared to basic UARTs.
Replacement Considerations
Direct replacements may be limited due to the proprietary nature of older SMSC controllers. Check Microchip's current portfolio for compatible serial controllers. Evaluate generic UART ICs if software abstraction layers can accommodate pin and register differences. Verify mechanical fit for the 28-pin DIP package.
