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.
