Philips Semiconductors
80C51 8-bit microcontroller family
4K/256 OTP/ROM, DAC, comparator, UART, reference
Preliminary specification
83C754/87C754
DESCRIPTION
The Philips 83C754/87C754 offers many of the advantages of the
80C51 architecture in a small package and at low cost.
The 8XC754 Microcontroller is fabricated with Philips high-density
CMOS technology. Philips epitaxial substrate minimizes CMOS
latch-up senitivity.
The 8XC754 contains a 4k × 8 ROM (83C754) EPROM (87C754), a
single module PCA, a 256 × 8 RAM, 11 I/O lines, two 16-bit
counter/timers, a two-priority level interrupt structure, a full duplex
serial channel, an on-chip oscillator, and an 8-bit D/A converter.
The EPROM version of this device, the 87C754, is available in
plastic one-time programmable (OTP) packages. Once the array
has been programmed, it ifs functionally equivalent to the masked
ROM 83C754. Thus, unless explicitly stated otherwise, all
references made to the 87C754 apply equally to the 83C754.
The 8XC754 supports two power reduction modes of operation
referred to as the idle mode and the power-down mode.
