The 82C52 is a single-chip high-performance programmable Universal Asynchronous Receiver/Transmitter (UART) and Baud Rate Generator (BRG) from Intersil Corporation. It uses Intersil Corporation's advanced Scaled SAJI IV CMOS process, supporting data rates up to 1M baud asynchronously with a 16X clock (16MHz clock frequency). The on-chip Baud Rate Generator can be programmed for any one of 72 different baud rates using a single industry standard crystal or external frequency source. When using any one of three industry standard crystals (1.8432MHz, 2.4576MHz or 3.072MHz), a unique pre-scale divide circuit can be designed to provide standard RS-232-C baud rates. A programmable buffered clock output (CO) is available and can be programmed to provide either a buffered oscillator or 16MHz digital clock output.
The Intersil 82C52 is a single-chip CMOS Serial Controller Interface designed as a high-performance Universal Asynchronous Receiver/Transmitter (UART) and Baud Rate Generator. It supports data rates up to 1 Mbaud asynchronously with a 16 MHz clock frequency.
| Data Rate | DC to 16MHz (1M Baud) |
|---|---|
| Power Supply | +5V |
The device supports data rates up to 1M baud asynchronously with a 16X clock.
The device operates with a single +5V power supply.
The Reset Input must be held high for at least two IX clock cycles to initialize the circuits.
