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
