The 8XC552 contains a non-volatile 8k × 8Meer info
read-only program memory (83C552), a
volatile 256 × 8 read/write data memory, five
8-bit I/O ports, one 8-bit input port, two 16-bit
timer/event counters (identical to the timers of
the 80C51), an additional 16-bit timer coupled
to capture and compare latches, a 15-source,
two-priority-level, nested interrupt structure,
an 8-input ADC, a dual DAC pulse width
modulated interface, two serial interfaces
(UART and I2C-bus), a “watchdog” timer and
on-chip oscillator and timing circuits. For
systems that require extra capability, the
8XC552 can be expanded using standard
TTL compatible memories and logic.
The P8xC592 is a single-chip 8-bit high-performanceMeer info
microcontroller with on-chip CAN-controller, derived from
the 80C51 microcontroller family.
It uses the powerful 80C51 instruction set.
Figure 1 shows a block diagram of the P8xC592.
The P8xC592 is manufactured in an advanced CMOS
process, and is designed for use in automotive and
general industrial applications. In addition to the 80C51
standard features, the device provides a number of
dedicated hardware functions for these applications.
