SpecificationsTemperature under bias:
Commercial (TC) ........................0°C to + 100°C
Storage temperature ..................65°C to + 125°C
Voltage on any pin with
respect to ground.......................... 0.5 V to VCC + 2.6 V*
Notes:
Stresses above those listed under Absolute Maximum Ratings may cause permanent device failure. Functionality at or above these limits is not implied. Exposure to absolute maximum ratings for extended periods may affect device reliability.
*X1 and X2 are not 5-V-tolerant and have a range of 0 .5 V to VCC.DescriptionThe Am186TMER and Am188TMER microcontrollers are part of the AMD E86™ family of embedded microcontrollers and microprocessors based on the x86 architecture. The Am186ER and Am188ER microcontrollers are the ideal upgrade for designs requi ring 80C186/80C188 microcont roller compatibility, increased performance, serial communications, a direct bus interface, and integrated memory.
The Am186TMER and Am188TMER microcontrollers integrate 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 port, synchronous serial interface, and programmable I/O (PIO) pins on one chip. Compared to the 80C186/ 80C188 microcont rolle rs, the Am186ER and Am188ER microcontrollers enable designers to reduce the size, power consumption, and cost of embedded systems, while increasing functionality and performance.
The Am186TMER and Am188TMER microcontrollers have been designed to meet the most common requirements of embedded products developed for the communications, office automation, mass storage, and general embedded markets. Specific applications include feature phones, cellular phones, PBXs, multiplexers, modems, disk drives, hand-held terminals and desktop terminals, fax machines, printers, photocopiers, and industrial controls.
