描述 Description

DESCRIPTION
The 73M2910L high performance micro-controller is based on the industry standard 8-bit 8032
implemented in an advanced submicron CMOS process. The processor has the attributes of the
8032, including instruction cycle time, UART, timers, interrupts, 256 bytes of on-chip RAM and
programmable I/O. The architecture has been optimized for low power portable modem or
communication applications by integrating unique features with the core CPU.FEATURES
•  8032 compatible instruction set
•  44 MHz Operation from 3.3 to 5.5V
•  HDLC support logic (Packetizer, 16 and 32 CRC, zero ID)
•  24 pins for user programmable I/O ports
•  8 pins programmable chip select logic or I/O for memory mapped peripheral eliminating glue logic
•  3 external interrupt sources (programmable polarity)
•  16 dedicated latched address pins
•  Multiplexed data/address bus
•  Instruction cycle time identical to 8032
•  Buffered oscillator (or OSC/2) output pin
•  1.8432 MHz UART clock available
•  Bank select circuitry to support up to 128k of external program memory
•  Also available in 100-Lead QFP and 100-Pin PGA packages
