P R O D U C T B R I E F 3.3 V, 2 Channel, Serial Optimized Communications Controller, with P Interface Building on Infineon's expertise, the SEROCCO satisfies 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 P interface can be operated as either 8 or 16 Bit with a maximum of 33 MHz bus speed and can be configured to be compatible with both Intel(R) 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) SEROCCO - 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 specific timers support protocol functions 64 byte TX and RX FIFO for each channel Integrated 4-channel DMA controller (SEROCCO-D version only) Microprocessor Interface Selectable 8 or 16 Bit data width Multiplexed or non-multiplexed operation Maximum 33 MHz bus timing with no wait-states General JTAG boundary scan test interface CMOS Technology 3.3 V power supply with 5 V tolerant I/O P-TQFP-100, P-TQFP-144 or LF-BGA-80 packages Temperature range of -40 C to +85 C Documentation and Support Package Data Sheet Application Notes Evaluation Systems EASY20525/32/42 SEROCCO-H/M/D PEB 20525/32/42 w w w . i n f i n e o n . c o m / h d l c N e v e r s t o p t h i n k i n g .
