73M2910L  
Microcontroller  
April 2000  
DESCRIPTION  
FEATURES  
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.  
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  
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.  
Bank select circuitry to support up to 128k of  
external program memory  
Also available in 100-Lead QFP and 100-Pin  
PGA packages  
For devices that require non-multiplexed address  
and data buses, eight latched outputs for the low  
byte of the address are available.
