Product Summary
The CDP1854ACE is a silicon-gate CMOS Universal Asynchronous Receiver/Transmitter (UART) circuit. The CDP1854ACE is designed to provide the necessary formatting and control for interfacing between serial and parallel data. The CDP1854ACE is capable of full duplex operation, i.e., simultaneous conversion of serial input data to parallel out-put data and parallel input data to serial output data.
Parametrics
CDP1854ACE absolute maximum ratings: (1)DC Supply-Voltage Range, (VDD): -0.5 to +11V; (2)Input Voltage Range, All Inputs: -0.5 to VDD + 0.5V; (3)DC Input Current, Any One Input: ±10mA; (4)Device Dissipation Per Output Transistor: 100mW; (5)Operating-Temperature Range (TA): -55 to +125℃.
Features
CDP1854ACE features: (1)Two Operating Modes: Mode 0 - Functionally Compatible with Industry Types Such as the TR1602A and CDP6402; Mode 1 - Interfaces Directly with CDP1800-Series Microprocessors without Additional Components; (2)Full or Half Duplex Operation; (3)Parity, Framing and Overrun Error Detection; (4)Baud Rate: DC to 200K Bits/s at VDD: 5V; DC to 400K Bits/s at VDD: 10V; (5)Fully Programmable with Externally Selectable Word Length (5-8 Bits), Parity Inhibit, Even/Odd Parity, and 1, 1-1/2, or 2 Stop Bits; (6)False Start Bit Detection.
