Key Features

• Core and ISA – Enhanced MIPS-II instruction set with a single 32-bit core providing standard MIPS-II functionality and DSP-style instructions for embedded processing tasks.
• On-chip Caches and MMU – 8 KB instruction cache and 2 KB data cache (both 2-way, lockable) plus an MMU with a 32-page TLB for virtual memory and memory protection.
• Memory Controller – Integrated SDRAM controller supporting 32-bit memory, four banks and up to 512 MB total SDRAM, enabling direct control of discrete or DIMM/SODIMM memories.
• Local Memory & Peripheral Bus – Local bus interface with a 23-bit address bus and 32-bit data bus for direct control of local memory and peripherals at up to 75 MHz operation (series capability).
• DMA and Timers – Four general-purpose DMA channels with scatter/gather, chaining, endianess swapping and support for unaligned and burst transfers; four 32-bit timer/counters for system timing and event management.
• Peripheral Interfaces – Integrated PCI bridge (32-bit, up to 50 MHz, 2.2 compatible), 16550-compatible UART (up to 1.5 Mb/s), SPI master interface and programmable I/O with per-pin interrupt capability.
• System Reliability – Built-in interrupt controller, programmable watchdog timers and EJTAG in-circuit emulator interface to aid debug and robust exception handling.
• Package and Environmental – Surface-mount 208-PQFP (28×28 mm) in tray packaging, industrial qualification with operating temperature -40 °C to 85 °C and RoHS compliance.

Typical Applications

• Embedded communications equipment – Suitable for integrated communications processors where MIPS-II core performance and on-chip peripheral integration reduce system complexity.
• Networking and I/O controllers – PCI interface, DMA channels and high-throughput memory controller support packet handling and I/O-heavy tasks.
• Industrial control systems – Industrial temperature qualification and programmable I/O/timers make it appropriate for control and monitoring applications.
• Memory-rich embedded appliances – On-chip SDRAM controller and sizable cache resources support applications requiring significant local memory bandwidth.

Unique Advantages

• Integrated communications-focused feature set: Combines a MIPS-II core with memory and I/O controllers to reduce external component count and simplify board design.
• Flexible memory subsystem: SDRAM controller with support for multiple banks and up to 512 MB of memory enables scalable system memory configurations.
• High-efficiency data movement: Four DMA channels with scatter/gather and chaining reduce CPU load for high-throughput transfers.
• Built-in system peripherals: PCI bridge, UART, SPI and programmable I/O provide broad connectivity without extensive external logic.
• Industrial-ready: Qualified for -40 °C to 85 °C operation and supplied in a robust surface-mount 208-PQFP package for demanding environments.
• Standards-compatible interfaces: 16550-compatible UART and PCI 2.2 compatibility simplify integration with common system components.
