2 DESCRIPTION

The P90CL301BFH is a highly integrated low-voltage

16/32-bit microcontroller especially suitable for digital

mobile systems such as GSM, DCS1900, IS54/95 and

other applications requiring low voltage, low power

consumption and high computing power. It is fully software

compatible with the 68000.

The P90CL301BFH optimizes system cost by providing

both standard as well as advanced peripheral functions

on-chip. The P90CL301BFH has a full static design and

special Idle, Standby and Power-down modes which allow

further reduction of the total system power consumption.

An 80-pin LQFP package dramatically reduces system

size requirements.

2.1 Compatibility between P90CL301AFH and

P90CL301BFH

For functional compatibility between P90CL301AFH

(SAC1 process) and P90CL301BFH (C100 process), the

following points should be considered when using the

P90CL301BFH:

• Wake-up; to wake-up the processor from Power-down

mode via the activation of an external SPn pin, it is

necessary to enable the interrupt mode first by setting

the corresponding bit in the SPCON register.

• SYSCON register; for the P90CL301AFH bits 11 to 15

in the SYSCON register should not be set in order to

keep additional functionality in the P90CL301BFH

inactive.
