Периферийный микроконтроллер P-51 фирмы Cybernetic Micro Systems

Cybernetic Micro Systems Peripheral 8051 System on a Chip


The P-51 "Peripheral 8051" is a new concept: An 8051 with built-in (E)ISA or PC-104 interface and supporting subsystems. These include downloadable Code RAM, dual port RAM, and all eleven IRQs to the host. Unlike classical 8051s, the P-51 naturally and easily interfaces to a host through simple standard buses, and its microsecond timing can provide real-time response to Windows applications.

USB-микроконтроллеры фирмы Cypress с ядром 8051

Cypress 8051-core USB-microcontrollers


Cypress's EZ-USB family of full-speed USB microcontrollers feature an enhanced 8051 core running at 24 MHz, and a RAM-based architecture, enabling the download of firmware from the host PC. The EZ-USB family supports high-bandwidth applications by providing the maximum number of endpoints allowed by the USB specification, as well as an efficient mechanism to move data on or off chip. For data intensive applications like modems, scanners, printers, and cameras, the EZ-USB family is the premier solution.

For even higher performance full-speed USB applications, Cypress has released the EZ-USB FX family. Based on the same architecture that has made the EZ-USB family so successful, the FX family (which stands for Faster and Xtended) implements an 8051 core that runs at 48 MHz, a 16-bit external datapath supported by on-chip FIFOs, as well as a DMA engine. The FX family is the highest performance full-speed USB solution available--until high-speed USB comes on line next year with USB 2.0 (with signaling rates up to 480 Mbits/second)! The EZ-USB and EZ-USB FX families offer software compatibility, and EZ-USB FX provides an excellent migration path to USB 2.0 for your customers. The I/O side is already capable of the high-speed signaling rates.

All Cypress USB family members are supported by one of our comprehensive Development Kits. These kits are the fast track to developing firmware and driver software for USB peripherals. Examples complete with source code are included to provide the designer with fast time to market.

Features EZ-USB and EZ-USB FX Series
  • High-Performance I/O port
  • RAM Architecture--4/8 Kbytes
  • Enhanced 8051 Core
  • Pin and Software Compatible Family
  • I2C Controller
  • USB 1.1 Compliant

Микроконтроллеры семейства E5 фирмы Triscend с ядром 8051

Triscend 8051-core E5 Family Microcontrollers


The Triscend E5 family is based on a performance-enhanced "turbo" version of the 8032 8-bit microcontroller. The E5 Family consists of 4 devices (all based on the "turbo" 8032) which vary in the amount of on-chip programmable logic, RAM, and I/Os.

The E5 is ideal for embedded systems applications that demand both time-to-market and high levels of customization. The E5 is compatible with existing, third-party 8032 firmware tools--from code development to in-system, real-time debugging. Thus a designer can utilize familiar processor development tools and code libraries.

Designers can configure E5 CSoC chips using the Triscend FastChip Development System. FastChip software allows designers to customize the processor peripherals using a "drag and drop" methodology. Designers simply select which soft peripheral is desired, then they "drag" it into place around the processor. From there FastChip makes the rest of the process automatic--code development can proceed without worrying about the implementation details of the soft peripheral.
E5 Highlights

  • High performance 8032 (10 MIPS at 40 MHz)
  • Binary and source code compatible with other 8032/8052 variants
  • Standalone operation from a single external memory (code + configuration)
  • Up to 64Kbytes of on-chip, dedicated system RAM
  • Up to 3200 Configurable System Logic (CSL) cells (up to 40,000 "ASIC" gates)
  • Power-down and power-management modes (low power mode consumption under 100 uA)
  • Compliant to the "CSI Socket" interface, allowing soft peripherals to be used on other CSoC Families
  • Two dedicated DMA Channels
  • On-chip breakpoint unit provides sophisticated debugging capability

CSL = Configurable System Logic. Implements any possible logic function with four or less inputs plus a flip-flop. Also can be used as a 16x1 ROM or RAM. Also can be used an 8x1 dual-port RAM or a 8-bit serial-in/serial-out shift register.

The embedded programmable logic is ideal for adding peripherals. Triscend's FastChip development system allows a designer to drag-and-drop functions from a pre-defined library or to custom create functions using standard logic design tools such as schematic capture or logic synthesis.
