MAXIM INTEGRATED / ANALOG DEVICES DS89C450ENL High-Speed Microcontroller

The DS89C450-ENL+ is an ultra-high-speed 8051-compatible flash microcontroller housed in a 44-pin TQFP package. It features a modern processor core capable of executing instructions up to 12 times faster than the original 8051 at the same clock speed, delivering typical performance improvements of up to 10 times. Operating at 1 MIPS per MHz, it can achieve up to 33 MIPS with a maximum clock frequency of 33 MHz. The microcontroller includes 1 KB of data RAM, a second hardware serial port, seven additional interrupts with two extra priority levels, a programmable watchdog timer, brownout monitor, and power-fail reset. It also supports dual data pointers with automatic increment/decrement and toggle capabilities. Memory access speed can be adjusted via stretch values up to 10 machine cycles for flexible external memory and peripheral interfacing. The device operates within a voltage range of 4.5V to 5.5V and an temperature range from -40°C to 85°C. It boasts 64KB of internal flash memory, supports single-cycle instructions in 30ns, and offers four paged memory-access modes. Additional features include 256 bytes of scratchpad RAM, a programmable clock divider, and full access to the external memory map, which can be dynamically adjusted by software. Typical applications include embedded systems development, automotive, industrial automation, consumer electronics, motor control, and security systems. Note: Due to high market demand, lead times may be extended, and delivery dates can fluctuate. The product is not eligible for discounts.
