What are the key features of TL16PIR552PH?
- Dual UART channels provide two independent asynchronous serial ports from a single 80-pin QFP IC, reducing chip count in multi-port serial designs
- IBM PC-AT bus compatibility enables seamless integration into legacy embedded systems and ISA bus industrial controller platforms
- Supports a maximum clock frequency of 16 MHz with 8-bit external data bus for straightforward interfacing to PC-compatible processors
- Asynchronous serial communication at up to 0.125 MBps suits low-to-medium-speed industrial and instrumentation data links
What is TL16PIR552PH used for?
The TL16PIR552PH is used in industrial PC-based controllers, embedded single-board computers, and legacy automation systems that require dual asynchronous serial ports on an ISA or PC-AT compatible bus. Its dual UART architecture supports simultaneous communication with two serial devices such as barcode scanners, modems, or PLC terminals from a single IC. Ruggedized industrial terminals and data acquisition systems benefit from its 80-pin QFP form factor and compatibility with established 8-bit bus architectures.
