GDS1110 Datasheet | Intel

Features The Intel®Strong ARM SA-1110 Microprocessor (SA-1110) is a device optimized for meeting portable and embedded application requirements. The SA-1110 incorporates a 32-bit Strong ARM RISC processor capable of running at up to 206 MHz. The SA-1110 has a large instruction and data cache, memory-management unit (MMU), and read/write buffers. The SA-1110 memory bus interfaces to many device types including synchronous DRAM (SDRAM), synchronous mask ROM (SMROM), and SRAM-like variable latency I/O devices with a shared data ready signal. In addition, the SA-1110 provides system support logic, multiple serial munication channels, a color/gray scale LCD controller, PCMCIA support for up to two sockets, and general-purpose I/O ports. s High performance - 150 Dhrystone 2.1 MIPS @ 133 MHz - 235 Dhrystone 2.1 MIPS @ 206 MHz s Memory bus - Interfaces to ROM, synchronous mask ROM (SMROM), Flash, SRAM, SRAM-like variable latency I/O, DRAM, and synchronous DRAM (SDRAM) - Supports two PCMCIA sockets s Low power (normal mode) † s 32-way set-associative caches - 16 Kbyte instruction cache - 8 Kbyte write-back data cache - <240 m W @1.55 V/133 MHz - <400 m W @1.75 V/206 MHz s Integrated clock generation - Internal phase-locked loop (PLL) - 3.686-MHz oscillator - 32.768-k Hz oscillator s 32-entry MMUs - Maps 4 Kbyte, 8 Kbyte, or 1 Mbyte s Power-management features - Normal (full-on) mode - Idle (power-down) mode - Sleep (power-down) mode s Write buffer - 8-entry, between 1 and 16 bytes each s Big and little endian operating modes 3.3-V I/O interface † s Read buffer - 4-entry, 1, 4, or 8 words 256 mini-ball grid array (m BGA) s s Power dissipation, particularly in idle mode, is strongly dependent on the details of the system design Order Number: 278241-005 April 2000 Description The SA-1110 is a general-purpose, 32-bit RISC microprocessor with a 16 Kbyte instruction cache (Icache), an 8 Kbyte write-back data cache (Dcache), a minicache, a write buffer, a read...
