Tolapai

Tolapai is the code name of Intel's embedded system-on-a-chip (SoC) which combines a Pentium M (Dothan) processor core, DDR2 memory controllers and I/O controllers, and a QuickAssist integrated accelerator unit for security functions.[1]

Overview

The Tolapai embedded processor has 148 million transistors on a 90 nm process technology, 1088-ball FCBGA with a 1.092mm pitch, and comes in a 37.5mm × 37.5mm package. It is also Intel's first integrated x86 processor, chipset and memory controller since 1994's 80386EX.[2]

Intel EP80579 integrated processor for embedded computing:

  • Serial: 1× synchronous serial port (SSP)
  • UARTs: 2× 16550-compatible UARTs
  • SMB: 2× System Management Bus (SMBus) interfaces
  • LPC: 1× Low Pin Count (LPC 1.1) interface
  • SPI: 1× Serial Peripheral Interface Bus (SPI) boot interface
  • RTC: Integrated real-time clock (RTC) support
  • EDMA: Enhanced DMA (EDMA) engine with low latency memory transfers; supports multiple peer-to-peer configurations
  • Operating temperature: 0 to 70 degrees C (most models); −40 to 85 degrees C (some models)
