The PCIe-Mini-ESCC module is a Dual Channel serial communication controller with 4K FIFO per Line. The PCIe-Mini-ESCC module is based on the Z85230 Enhanced Serial Communication Controller, with larger FIFOs and several SDLC improvements from Zilog. This module provides two asynchronous ports up to 230Kbaud and synchronous ports up to 2Mbaud full-duplex channels, with an independent baud rate generator for each channel.
Asynchronous capabilities
- 5, 6, 7 or 8 bits/character
- 1, 1.5 or 2 Stop bits
- Odd or Even parity
- Parity, Overrun and Framing Error detection
- Up 230Kbits
Synchronous/Isosynchronous capabilities
- Up to 1/4 of PCLK using an external Clock
- Up to 1/8 of PCLK using DPLL in FM mode
- Up to 1/16 of PCLK using DPLL in NRZI
- Up to 2Mbits In Synchronous
Character-oriented synchronous capabilities
- Internal or external synchronization
- 1 or 2 SYNC characters (6 or 8 bits/character)
- NRZ, NRZI, or FM encoding/decoding, as well as Manchester decoding
- Cyclic redundancy check (CRC-16, CRC-CCITT) generation/detection
SDLC/HDLC Capabilities
- Automatic zero insertion and detection
- Automatic flag insertion between messages
- Address field recognition
