VG-CD1865, Serial Communication Controller

The Amphus VG-CD1865 Serial Communication Controller is pin compatible and functionally equivalent to the Intel discontinued SCD1865 Serial Communication Controller.   It is a universal asynchronous receiver/transmitter with eight full-duplex serial channels, each has separate 8 byte transmit and receive FIFOs. By moving data efficiently from the serial channels to the host system, the Amphus VG-CD1865 reduces overhead and yields an eight-fold improvement in system throughput.

Product Overview

• 8 full-duplex 230.4 Kbit/sec. serial channels
• Independent baud-rate generators for each transmitter and receiver to support data rates up to 115.2 Kbps
• Generation and detection of special characters
• 5 modem/general-purpose I/O signals per channel
• Up to 60 MHz system clock
• Simultaneous interrupt requests for three classes of interrupts: Rx, Tx, and modem state changes
• Sophisticated interrupt schemes, including:

  - Vectored interrupts
  - Fair Share interrupts
  - Good Data* interrupts for improved throughput
  - Simultaneous interrupt requests for three classes of interrupts: Rx, Tx, and modem state     changes

• On-chip FIFO - 8 bytes each for Rx, Tx, and status FIFOs
• On-chip flow control
• In-band (Xon, Xoff generation and detection)
• Out-of-band (DTR/DSR or RTS/CTS)
• 100-pin MQFP package

Lead-Free version of VG-CD1865 is available now.   It is a Pin Compatible and Functional Equivalent to VG-CD1865.   It has the same silicon die as in VG-CD1865.   The only difference is the package material composition for the package used. Lead-content and other non-friendly environmental substances are completely removed from the package materials.   Because of the material differences, solder reflow profile for VG-CD1865-LF is slightly different from VG-CD1865.   The VG-CD1865-LF is fully compliant to RoHS environmental standards.
