Building on Lantiq‘s expertise, the SEROCCO satisfi es a system designer‘s need for a multiprotocol
serial communications controller that operates at 3.3 V.
Additionally, the SEROCCO provides a throughput of up to 16 Mbit/s full duplex on each port and
deep (64 byte) TX and RX FIFO‘s. The μP interface can be operated as either 8 or 16 Bit with
a maximum of 33 MHz bus speed and can be confi gured to be compatible with both Intel® or
Motorola® style processors.
The design of the SEROCCO is based upon the industry standard ESCC2 (SAB 82532) and DSCC4
(PEB 20534) and supports HDLC, BISYNC, ASYNC and PPP protocols. A DMA controller handshake
interface is provided. SEROCCO is available in three versions optimized for your application.
Applications
Serial Link Control •
Intersystem or Backplane Communication •
LAN/WAN Internetworking •
Maintenance Ports on WAN Switches/Routers •
Mobile Base Stations •
Workstations, Server, Modems •
Features
Two independent serial multiprotocol communication controllers in three versions (-H, -M, -D) •
Each channel supports HDLC, BISYNC, ASYNC and PPP protocols •
Serial Interface •
- Full duplex data rates on each channel up to 16 Mbit/s
- Enhanced time-slot assignment (8 Mbit/s PCM link)
- Octet-, bit- synchronous and asynchronous PPP interface modes
- Asymmetric data rates for RX and TX direction
- Clock gating and gapping
- Modem control signals (/CTS, /RTS, …)
- Internal DPLL and baud rate generator per channel
- Internal oscillator
A large set of layer-2 protocol functions (LAPD Automode, SS7) reduces bus and host CPU load •
Two channel specifi c timers support protocol functions 64 byte TX and RX FIFO for each channel •
Integrated 4-channel DMA controller (SEROCCO-D version only) •
