Frequently Asked Questions
How many UART channels does the TL16CP554APM provide?
The TL16CP554APM provides four independent asynchronous UART channels in a single IC, making it a quad UART (QUART). Each channel operates independently with its own transmit and receive logic, baud rate generation, and status registers, allowing four simultaneous asynchronous serial communication links from a single device.
What is the maximum data rate of the TL16CP554APM?
The TL16CP554APM supports a maximum clock frequency of 16MHz and a maximum data transfer rate of 125 kbps (0.125 MBps) per channel using NRZ (Non-Return-to-Zero) encoding. This is sufficient for standard RS-232, RS-485, and similar asynchronous serial protocol applications in embedded and industrial equipment.
What host interface does the TL16CP554APM use?
The TL16CP554APM interfaces to a host processor through an 8-bit parallel data bus and a 3-bit address bus, allowing the host to access the registers of each of the four UART channels. It also has no boundary scan capability, making it a straightforward parallel-bus peripheral for legacy and embedded processor systems.
What package does the TL16CP554APM come in?
The TL16CP554APM is housed in a 64-pin PQFP (Plastic Quad Flat Package), designated by the JESD-30 code S-PQFP-G64. This surface-mount package provides a reasonable footprint for high pin count ICs used in industrial and communication board designs, and the 'PM' suffix in the part number corresponds to this specific package variant.
