Description



Features:

• 3.3V to 5.5V operation to 30MHz over the industrial temperature range, available in 100 pin LQFP package.
• 4 onboard SCC's for 2B+D plus Asynch port, or any combination of 4 sync/async ports. Industry standard IDL and SCP interfaces for glueless connection to U-Chip or S/T chip. Sync data rates to 4Mbps. Asynch data rates to 921.6Kbps with/without autobaud.
• Complete onboard DRAM controller supports 5 banks of up to 8MBytes each. Interfaces without glue chips to most industry standard DRAMs.
• Memory controller also generates 6 chip selects to support SRAM, ROM, Flash, EPROM, peripheral chips, etc. without external glue.
• Supports off-chip addressing up to 32 MB (2 x 2**24 address spaces) in Harvard architecture, or 16MB in unified memory configuration.
• A clock output reference "ClkOut" is added to simplify external bus interfacing.
• High performance 8-channel DMA Controller offloads the CPU for moving data to/from SCC's and memory.
• Two standard counter/timers with enhanced features (same as XA-G3 T0, T1). Both timers have a toggle output capability.
• Watchdog timer.
• Seven standard software interrupts, plus four High Priority Software Interrupts, plus 7 levels of Hardware Event Interrupts.
• Active low reset output pin indicates all internal reset occurrences (watchdog reset and the RESET instruction). A reset source register allows program determination of the cause of the most recent reset.
• 32 General Purpose I/O pins, each with 4 programmable output configurations.
• Power saving operating modes: Idle and Power-Down. Wake-Up from power-down via an external interrupt is supported.

Description

The XA-SCC device is a member of Philips' XA (eXtended Architecture) family of high performance 16-bit single-chip
microcontrollers.
The XA-SCC includes a complete onboard DRAM controller capable of supporting up to 32MegaBytes of DRAM.

The XA-SCC device combines many powerful communications oriented peripherals on one chip. 4 Full Function SCC's, 8 DMA channels (2 per SCC), hardware autobaud up to 921.6Kbps, IDL TDM interface, two timers/counters, 1 watchdog timer, and multiple general purpose I/O ports. It is suited for many high performance embedded communications functions, including ISDN terminal adaptors and Asynchronous Muxes.
