ScanLogic to release two new additions to their highly popular and unique, USB host/slave chip series promising greater flexibility for computer devices.

Burlington, MA, April 10 - ScanLogic Corporation continues to demonstrate its leading position in the USB semiconductor market by announcing today the upcoming release of two new additions to their USB host/slave chip series in late spring. "What makes the combination host and slave chip unique is that a peripheral, which has traditionally relied on a host PC to receive commands, is now capable of operating as a host allowing it to connect and send commands to other USB peripherals," said CEO and founder, Israel Zilberman. "In addition, since the chip operates in either host or slave mode, this same device can switch automatically to slave or "peripheral" mode to communicate to a PC." The two new chips - identified as the SL811HS and the SL1612HS - support both USB (version 1.1) transfer rates of 1.5 Mbps (slow speed) and up to 12 Mbps for fast speed USB peripherals in both host and slave modes. The chips are available in different packages including a 48-pin low profile LPQFP package. Both support low power mode, 3.3/5v I/O interface logic, provide direct memory access (DMA) operations in slave mode and have built-in DPLL allowing the use of a low-cost external 6/12 MHz crystal.

The SL811HS is an 8-bit single port USB controller chip that automatically generates SOF, CRC5/CRC16, and supports root hub functions. The SL811HS can interface to a wide range of microcontrollers or digital signal processors (DSP). Samples available in May.

The SL1612HS does all of this plus includes a second dual speed USB host/slave port. In slave mode, its unique architecture allows support of up to 16 endpoints, which is double the standard for a slave chip. These endpoints are completely software configurable making the chip extremely flexible for developers. In addition, The SL1612HS has an 8/16-bit data port, 8 GPIO ports, can interface to an external flash EEPROM, has a 1.5KB memory buffer, and supports maximum packet transfers in Isochronous, Bulk, Interrupt and Control modes. Samples available in June.

As with all ScanLogic products, these two new chips will be accompanied by a comprehensive developer's kit that includes sample chips, demo boards, reference designs, sample firmware and host/slave drivers allowing customers to have a working USB device in only 2 - 3 weeks.

SL11H/SL811HS, and SL1612HS ScanLogic controllers are an ideal solution for many peripherals that also function as standalone devices. Since both host/slave modes are automatically detected, a peripheral becomes host to a variety of other USB peripherals. Hand-held devices such as PDAs, cellular phones, MP3 Players and communication devices like Set-Top Boxes can communicate to other USB peripherals such as printers, external storage devices, game pads, keyboards and joysticks. This same host device can then switch to slave mode allowing it to connect to a PC. All of this is possible with the host/slave chip because the host function is now within the peripheral rather than only within the PC.

ScanLogic will exhibit at the upcoming WinHEC 2000 conference in New Orleans, booth #226, this April 24^th – 26^th.
