Product Summary
The AM186ER-40KC is a 16-Bit Embedded Microcontroller. The AM186ER-40KC has been designed to meet the most common requirements of embedded products developed for the communications, office automation, mass storage, and general embedded markets. The AM186ER-40KC integrates memory and the functions of the CPU, nonmultiplexed address bus, timers, chip selects, interrupt controller, DMA controller, PSRAM controller, watchdog timer, asynchronous ser ia l por t , synchronous serial interface, and programmable I/O (PIO) pins on one chip. The specific applications of the AM186ER-40KC include feature phones, cellular phones, PBXs, multiplexers, modems, disk drives, hand-held terminals and desktop terminals, fax machines, printers, photocopiers, and industrial controls.
Parametrics
AM186ER-40KC absolute maximum ratings: (1)Temperature under bias: Commercial (TC):0℃ to + 100℃; (2)Storage temperature:–65℃ to + 125℃; (3)Voltage on any pin with respect to ground:–0.5V to VCC + 2.6V.
Features
AM186ER-40KC features: (1)lower system cost with high performance; (2)32Kbytes of internal SRAM; (3)internal SRAM provides same performance as zero-wait-state external memory; (4)supports zero-wait-state operation at 50MHz with 55ns external memory; (5)1-Mbyte memory address space; (6)64-Kbyte I/O space; (7)non-multiplexed address bus provides glue-less interface to external RAM and ROM; (8)phase-locked loop enables processor to operate at up to four times clock input frequency; (9)thirty-two programmable I/O pins; (10)asynchronous serial port allows full-duplex, 7-bit or 8-bit data transfers; (11)DMA to and from asynchronous serial port; (12)synchronous serial interface allows half-duplex, bidirectional data transfer to and from ASICS; (13)reset configuration register; (14)additional external interrupts; (15)hardware watchdog timer can generate NMI or system reset.
