The Intel CHMOS M82510 is designed to increase system efficiency in asynchronous environments such as
modems serial ports including expanding performance areas MCS -51 9-bit format and high speed async
The functional support provided in the M82510 is unparalleled 2 baud rate generators timers provide inde-
pendent data rates or protocol timeouts a crystal oscillator and smart modem I O simplify system logic New
features dual FIFOs and Control Character Recognition (CCR) dramatically reduce CPU interrupts and in-
crease software efficiency The M82510’s software versatility allows emulation of the INS 8250A 16450 for
IBM PC AT compatibility or a high performance mode configured by 35 control registers All interrupts are
maskable at 2 levels The multi-personality I O pins are configurable as desired A DPLL and multiple sampling
of serial data improve data reliability for high speed asynchronous communication The compact 28-pin
M82510 is fabricated in CHMOS III technology and includes a software powerdown option
