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.
