Motorola announces three derivatives of popular 68302 communications processor; market-focused solutions for low-power, PCMCIA, wireless and internetworking applications.

AUSTIN, Texas--(BUSINESS WIRE)--March 20, 1995--Motorola's Microprocessor and Memory Technologies Group today announced three additions to its 68302 (302) Integrated Multiprotocol Processor family of communications processors: the 68LC302, 68PM302 and 68EN302.

The three derivative products are based on the widely used 302 architecture with new functions added for low-power, PCMCIA, wireless and internetworking applications. First introduced in September 1989, the 302 is a highly integrated processor for use in data communications applications. The 302 has enjoyed consistent success and continues to win major designs in the modem, line card, PBX, base station and ISDN markets. By introducing the 302 derivatives, Motorola is broadening its data communications processor offerings for users who require specific functionality and cost-effective semiconductor solutions for newly developed markets.

"The 68302 has established itself as the leading embedded processor for communications applications," said Trey Oprendek, marketing manager, Motorola Data Communications Operation. "The new derivatives will expand Motorola's product offerings, making the 302 family an even more desirable solution for next-generation applications and for the growing PCMCIA and internetworking markets."

The 68302 is currently being used by over 500 customers worldwide. Customers currently using the 302 include Alcatel, AT&T Paradyne, Motorola, Northern Telecom and Xircom. (For additional information, please see the attached list).

"The high integration and performance of the 68302 architecture enables AT&T Paradyne to design top-of-the-line V.32 bis and V.34 modem products," said Pete Schramm, AT&T Paradyne. "We are excited about the 302 derivatives and are actively evaluating them for use in future designs."

"Xircom has been a long-standing customer of the 68302 because it provides the performance and flexibility that we look for in designing our mobile networking products," said Jim Soriano, vice president of product development, Xircom. "We are now incorporating the LC302 into our cost- and power-sensitive PCMCIA products to meet the changing needs of this market."

68302 Architecture

The 302 integrates on a single chip the functions of many peripheral chips, augmenting the high performance of the 68000 microprocessor. It is designed to carry out a complete range of protocol dependent functions and supports five major protocols: HDLC/SDLC, UART, BISYNC, DDCMP and transparent. These protocols can be supported by any of the processor's three serial communication channels (SCCs). The integrated SCCs operate independently, allowing the 302 to support up to three different protocols simultaneously.

The 302 contains a RISC-based communications processor and system integration circuitry, including an independent DMA controller, two general purpose timers/counters, a clock generator, DRAM refresh support, an interrupt controller, parallel output/input (I/O) ports and chip selects. Designers of wide-area networks, satellite communications, modems, telephone switching equipment and computer I/O subsystems benefit from the 302's unmatched level of integration, cost-effectiveness and reduced system design time.

The concept behind the 302 architecture has been incorporated into Motorola's other communications processors, including the 68302 (QUICC) and the highly-integrated 68356. The 68360 is the first controller to integrate high-performance processing power with LAN and WAN functionality. The 68356 is the first commercially available monolithic device to offer general purpose DSP and RISC microprocessors on a single chip.

68LC302

The 68LC302 (LC302) is a low-cost, reduced-functionality alternative to the 68302, incorporating a static core processor, less one SCC. The static core enables the LC302 to operate down to direct current (DC), utilizing significantly less power and extending battery life when in low-power modes. The LC302 also incorporates a phase lock loop (PLL), enabling users to multiply-up the clock source to use less system power. This makes the LC302 an optimal solution for applications that may not require the entire range of 68302 performance, such as V.32 bis and V.34 modems, ISDN terminal adapters, cable interface units and portable devices. It is also useful in space- and height-limited applications because it is the first 302 solution found in a 100-pin TQFP.

Customers currently evaluating the 68LC302 include Continuum, Diva Communications, Metricom, Motorola Messaging, Information and Media Sector (MIMS), NetComm, Scientific Atlanta, Trimble Navigations and Xircom.

68PM302

The 68PM302 (PM302) integrates a PCMCIA controller into the 302 core architecture to accommodate PCMCIA-based applications such as data modem, GSM modem, ISDN, wireless LAN and CDPD cards. The power requirements of the PM302 are comparable to the LC302 because it incorporates the same static core, PLL and low-power mode capabilities.

The PM302 is capable of operating as either a 302 with PCMCIA functionality or as a stand-alone, fully-static 302. When in PCMCIA mode, the PM302 provides support for a PC card 16-slave interface capable of handling 8- or 16-bit data and host DMA. The PM302 also includes a UART 16550-compatible interface to provide a direct connection to the serial port of the AT bus. The 68000 bus supports 20-bit addressing and 8- or 16-bit data. When not in PCMCIA mode, the PM302 becomes a static version of the 302 and provides full 24-bit addressing, plus additional input pins. The PM302 is offered in a 144-pin TQFP, making it an ideal solution for PCMCIA cards.

The PM302 minimizes overall system costs by reducing board space, decreasing power requirements and eliminating the need for an external PCMCIA controller. Customers currently evaluating the PM302 include Allen-Bradley Datamyte, Digi International Israel, Inc., Nokia and Samsung Electronics Company, Ltd.

68EN302

The 68EN302 (EN302) integrates Ethernet capability and a DRAM controller to provide a cost-effective solution for the low-end bridge and router markets. The EN302 provides all three of the 302 SCCs and integrates an additional Ethernet interface.

The Ethernet controller has a 16-bit interface, is IEEE 802.3 compatible and resides on the 68000 bus. The DRAM controller provides a glueless interface to DRAM, SRAM and EPROM, and has been enhanced to support both external bus masters and parity.

When operating at 20 MHz, the EN302 supports data rates of up to 10 Mbps. It incorporates separate 128-byte FIFOs for transmit and receive functions, eliminating the CPU intervention required for collision fragments. The EN302 effectively supports address recognition found in bridges and routers via a 64-entry, 48-bit content-addressable memory (CAM). By incorporating this functionality in hardware, the EN302 reduces the software overhead required of the CPU.

To complement the EN302, Motorola offers the MC68160 Enhanced Ethernet Serial Transceiver (EEST), an integrated serial interface adapter (SIA) and transceiver, for a complete Ethernet solution.

The high level of integration enables the EN302 to reduce board space requirements and lower overall system costs for internetworking applications, including bridges, routers, industrial control and remote-access dial-in. Another popular use of the EN302 will be in ISDN-to-Ethernet routers.
