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 × 8 ROM (83C749) EPROM (87C749), a 64 × 8 RAM, 21 I/O lines, a 16-bit auto-reload counter/timer, a 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.
