73M2910L

73M2910L Microcontroller April 2000 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. A key feature is a user friendly HDLC Packetizer, accessed through the special function registers. It has a serial I/O, hardware support for 16 and 32-bit CRC, zero insert/delete control, a dedicated interrupt and a clear channel mode for by-passing the packetizer. Other features include additional user programmable I/O with programmable bank select and chip select logic, designed to eliminate board level glue logic. It also includes two general-purpose input ports with programmable wakeup capability. For devices that require non-multiplexed address and data buses, eight latched outputs for the low byte of the address are available.
