Product data
P89C60X2/61X2
DESCRIPTION
The Philips microcontrollers described in this data sheet are
high-performance static 80C51 designs. They are manufactured in
an advanced CMOS process and contain a non-volatile Flash
program memory that is programmable in parallel (via a parallel
programmer) or In-System Programmable (ISP) via boot loader.
They support both 12-clock and 6-clock operation.
The P89C60X2 and P89C61X2 contain 512 bytes RAM and
1024 bytes RAM respectively, 32 I/O lines, three 16-bit
counter/timers, a six-source, four-priority level nested interrupt
structure, a serial I/O port for either multi-processor
communications, I/O expansion or full duplex UART, and on-chip
oscillator and clock circuits.
In addition, the devices are static designs which offer a wide range
of operating frequencies down to zero. Two software selectable
modes of power reduction — idle mode and power-down mode —
are available. The idle mode freezes the CPU while allowing the
RAM, timers, serial port, and interrupt system to continue
functioning. The power-down mode saves the RAM contents but
freezes the oscillator, causing all other chip functions to be
inoperative. Since the design is static, the clock can be stopped
without loss of user data. Then the execution can be resumed from
the point the clock was stopped.
