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.

 

P-51 Features

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.
