Intel will debut a new processor for embedded systems by the end of this year, codenamed Tolapai. The special thing about this new CPU is that it features an integrated north and south bridge.

The 65nm Tolapai processor is based on the Pentium M architecture and will use a 1088-ball FCBGA package and will measure only 3.75 x 3.75cm. It has an integrated DDR2 memory controller, that supports up to 2GB 400MHz, 553MHz and 800MHz memory with dual-channel and ECC support.
Features of Tolapai include: Gigabit Ethernet (RGMII, RMII), IEEE 1588 Time Synch, 1MDIO, 133x GPIO, 2組UART, 2 SMBus, 2 Controller Area Network; CAN, 1 Sync Serial Port (SSP), 1 16Bit PCI, 5 PCI-E, 2 SATA 2.0 and 2 USB 2.0.

What’s more, there is also an Acceleration Services edition for Tolapai, providing enhanced hardware security services including AES, 3DES, RC4, MD5, SHA-1, SHA-224-256-384-512, HMAC, ESA and DSA up to 1.6Gbps. And its TDM interface could make IP Telephony be possible.


The Tolapai will be launched at 600MHz, 1.06GHz and 1.2GHz. The TDP ranges from 13W to 25W. It will compete against the VIA C7 and AMD Geode processors.
