FEATURES
80C51 type core
On-chip oscillator with a maximum frequency of 16 MHz
(maximum 0.75
μ
s instruction cycle)
A DDC interface:
– That fully supports DDC1 with specific hardware
– That is DDC2B, DDC2B+, DDC2AB (ACCESS.bus)
compliant, based on a dedicated hardware I
2
C-bus
interface.
– Contains a specific AUX-RAM buffer with
programmable size (128 or 256 bytes) that can be
used for DDC operation and shared as system RAM
Automatic mode detection by hardware to capture the
following information:
– HSYNC frequency with 12-bit resolution
– VSYNC frequency with 12-bit resolution
– HSYNC and VSYNC polarity
– HSYNC and VSYNC presence; needed for the VESA
Device Power Management Signalling (DPMS)
standard
On-chip sync processor comprising:
– Composite sync separation
– Free running mode
– Clamping
– Pattern generation
Two specific ports for the software I
2
C-bus interface
4 analog voltage outputs derived from an 8-bit
Digital-to-Analog Converter (DAC)
Ten 8-bit Pulse Width Modulation (PWM) outputs for
digital control application
One 14-bit PWM output for digital control application
One 4-bit Analog-to-Digital Converter (ADC) with 2 input
channels (for keyboard interface)
LED driver port (Port 0); eight port lines with 10 mA drive
capability
One 8-bit port only for I/O function
20 derivative I/O ports with the specific port type
configuration in each alternative function
Watchdog Timer with a programmable interval
On-chip Power-on-reset for low power detection
Special Idle and Power-down modes for reduced power
operation
Optimized for Electromagnetic Compatibility (EMC)
Operating temperature:
25 to +85
°
C
Single power supply: 4.4 to 5.5 V.
1.1
Differences from the 80C51 core
No external memory connection; signals EA, ALE and
PSEN are not present.
Port 1, Port 2 and Port 3 (P3.0 to P3.3 only) mixed with
other derivative functions.
Timer 0/Counter 0 and Timer 1/Counter 1: external
input is removed.
External interrupt 0/INT0 replaced by Mode detection
function.
Standard serial interface (UART) and its control register
are removed.
Wake-up from Power-down mode is also possible by
means of an interrupt.
