Dallas Semiconductor

Category:  

Microcontroller Cores (new products)

Date:  

03-Nov-98
Dallas Texas (microcontroller.com) - Dallas Semiconductor  has introduced a new microcontroller to its high-speed 8051 family, p/n DS87C550 with a true 10-bit A/D converter and 8Kbytes of on-board EPROM memory.

Features
p/n: DS87C550

  • 8-bit 8051 CISC Core at 4 clocks/machine cycle
  • Dual data pointer operation
  • DC to 33MHz clock rate
  • Oscillator fail detect
  • 5V operation
  • 8Kbytes EPROM Memory
  • 1K on-chip SRAM
  • Watchdog Timer
  • 4-channels of 8-bit PWM
  • 8-channel 10-bit A/D @ 1.9µsec conversion time
  • Advanced Power Saving Modes
  • 80C52-Compatible UART
  • SPI interface

Pricing and Availability
Packaged in a 68-pin PLCC, a 68-pin windowed CLCC and an 80-pin PQFP, the DS87C550 EPROM Microcontroller with 10-bit A/D starts at $11.00 each in 10,000-piece quantities.

For more information on these products, contact Dallas Semiconductor.

Code Compatibility
The DS87C550 is code-compatible with other 80C51 and 80C52 microcontrollers, with increased performance due to its redesigned 80C52 core.
