Quick Detail:

Semiconductor - EPROM High-Speed Micro with A/D and PWM

Description:

The DS87C550 EPROM High-Speed Micro with A/D and PWM is a member of the fastest 100% 8051-

compatible microcontroller family available. It features a redesigned processor core that removes wasted

clock and memory cycles. As a result, it executes 8051 instructions up to three times faster than the

original architecture for the same crystal speed. The DS87C550 also offers a maximum crystal speed of

33 MHz, resulting in apparent execution speeds of up to 99 MHz.

The DS87C550 uses an industry standard 8051 pin-out and includes standard resources such as three

timer/counters, and 256 bytes of scratchpad RAM. This device also features 8 kbytes of EPROM with an

extra 1 kbyte of data RAM (in addition to the 256 bytes of scratchpad RAM), and 55 I/O ports pins. Both

One-Time-Programmable (OTP) and windowed packages are available.

Applications:

87C52-Compatible

-  8051 pin- and instruction set-compatible

-  Three 16-bit timer/counters

-  256 bytes scratchpad RAM

On-chip Memory

-  8 kbytes EPROM (OTP & Windowed Packages)

-  1 kbyte extra on-chip SRAM for MOVX access
