Product Summary
The DS87C550QCL is an EPROM High-Speed Micro with A/D and PWM. It 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 DS87C550QCL also offers a maximum crystal speed of 33 MHz, resulting in apparent execution speeds of up to 99 MHz.
Parametrics
DS87C550QCL absolute maximum ratings: (1)Voltage on Any Pin Relative to Ground -0.3V to (VCC +0.5V); (2)Voltage on VCC Relative to Ground -0.3V to 6.0V; (3)Operating Temperature -40 to +85℃; (4)Storage Temperature -55 to +125℃; (5)Soldering Temperature 160℃ for 10 seconds.
Features
DS87C550QCL features: (1)Selects effective on-chip ROM size from 0 to 8k; (2)Allows access to entire external memory map; (3)Dynamically adjustable by software; (4)8051 pin- and instruction set-compatible; (5)Three 16-bit timer/counters; (6)256 bytes scratchpad RAM.
