DESCRIPTION
The 73M2910L high performance micro-controller is
based
implemented in an advanced submicron CMOS
process. The processor has the attributes of the
8032, including instruction cycle time, UART, timers,
interrupts,
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.
