AM186CU-25KI

The AM186CU-25KI is one member of the AM186 family which is designed as the high performance, 80C186- and 80C188-compatible, 16-bit embedded microcontroller. AM186CU-25KI integrates a complete DRAM controller to take advantage of low DRAM costs and have been designed to meet the most common requirements of embedded products developed for the communications, office automation, mass storage, and general embedded markets. Also the specific applications include PBXs, multiplexers, modems, disk drives, hand-held and desktop terminals, fax machines, printers, photocopiers, and industrial controls.

Features of the AM186CU-25KI are:(1)lower system cost with higher performance;(2)3.3-V ± 0.3-V operation (Am186EDLV microcontrollers);(3)includes programmable CAS-before-RAS refresh capability;(4)20-, 25-, 33-, and 40-MHz operating frequencies;(5)zero-wait-state operation at 40 MHz with 70-ns static memory;(6)1-Mbyte memory address space;(7)processor operates at the clock input frequency;(8)programmable interrupt controller with up to 8 external and 8 internal interrupts;(9)two independent DMA channels;(10)a pulse-width demodulation option;(11)independent serial port baud rate generators.

The absolute maximum ratings of the AM186CU-25KI can be summarized as:(1)storage temperature:-65°C to +125°C;(2)voltage on any pin with respect to ground:-0.5 V to Vcc+0.5 V;(3)input low voltage:-0.5 to 0.2Vcc0.3 V;(4)clock input low voltage:-0.5 to 0.8 V;(5)input capacitance:10 pF;(6)output or I/O capacitance:20 pF.
