DESCRIPTION
The Philips 83C749/87C749 offers many of the advantages of the
80C51 architecture in a small package and at low cost.
The 8XC749 Microcontroller is fabricated with Philips high-density
CMOS technology. Philips epitaxial substrate minimizes CMOS
latch-up sensitivity.
The 8XC749 contains a 2k
64
fixed-priority level interrupt structure, an on-chip oscillator, a five
channel multiplexed 8-bit A/D converter, and an 8-bit PWM output.
The EPROM version of this device, the 87C749, is available in
plastic one-time programmable (OTP) packages. Once the array
has been programmed, it is functionally equivalent to the masked
ROM 83C749. Thus, unless explicitly stated otherwise, all
references made to the 83C749 apply equally to the 87C749.
The 83C749 supports two power reduction modes of operation
referred to as the idle mode and the power-down mode.
