6.1
General
The P83C880, P83C180, P83C280, P83C380 and
P87C380 8-bit microcontrollers are manufactured in an
advanced CMOS process and are derivatives of the
80C51 microcontroller family. They have the same
instruction set as the 80C51.
They contain 512 bytes of data memory (RAM). ROM:
8 kbytes (P83C880); 16 kbytes (P83C180); 24 kbytes
(P83C280); 32 kbytes (P83C380) and 16 kbytes of
EPROM for the P87C180. The microcontrollers are
intended for use in monitors ranging from 14" to 21" that
can be controlled from the outside (e.g. by a PC) via the
external DDC interface.
In addition to the 80C51 standard functions, they provide a
number of dedicated hardware functions for monitor
application. Eight general I/O ports plus 20 functions
combined I/O ports cater for application requirements
adequately.
Ten sets of 8-bit PWM deliver the digital waveform for
analog control purposes. One 14-bit PWM can support
F to V application. The keyboard interface is achieved via
a 4-bit ADC. A Watchdog Timer with a maximum count
period of 5 s prevents the processor running out of control
due to malfunction. Four channels of linear DAC with 8-bit
resolution support more accurate analog controls.

C-bus interface is dedicated for the internal
connection. A DDC interface will cover all DDC protocols,
including DDC1, DDC2B, DDC2AB and DDC2B+.
A hardware mode detector will facilitate mode detection
even in power reduced modes, e.g. Idle mode.
The versatile HSYNC and VSYNC outputs can be
generated to serve the desired application. In the free
running mode, two display patterns can highlight the status
of the monitor. Accordingly, the following items will be
supported by these microcontrollers:
Mode detection for:
– Horizontal sync (HSYNC) frequencies from below
15 kHz up to 150 kHz
– Vertical sync (VSYNC) frequencies from below 40 Hz
up to 200 Hz
ACCESS.bus interfacing with external devices, e.g. PCs
DDC1, DDC2B, DDC2AB and DDC2B+ protocols as
defined in the VESA DDC standard
Device Power Management Signalling (DPMS) as
described in VESA DPMS proposal.
Figure 1 shows the block diagram functions.
