8.1 General
The SZF2002 is a stand-alone high-performance CMOS
microcontroller designed for use in real-time applications
such as wireless telephone and mobile communications,
instrumentation, industrial control, intelligent computer
peripherals and consumer products.
The device provides hardware features, architectural
enhancements and new instructions to function as a
controller for applications requiring up to 256 kbytes of
program memory and/or up to 6144 + 256 bytes of on-chip
data memory.
The SZF2002 contains a 6-kbyte program memory; a
static 6144 + 256 byte data memory (RAM); 24 I/O lines;
three 16-bit timer/event counters; a fifteen-source two
priority-level, nested interrupt structure, a 6-channel 8-bit
ADC, a Watchdog Timer and a Pulse Width Modulation
output.
Two serial interfaces are provided on-chip:
• A standard UART serial interface
• A standard I2C-bus serial interface with a transfer speed
of up to 400 kbits/s (depending on clock frequency).
The I2C-bus serial interface has byte oriented master
and slave functions allowing communication with the
whole family of I2C-bus compatible devices.
The device has two software selectable modes of reduced
activity for power reduction:
• Idle mode: freezes the CPU while allowing the
derivative functions (timers, serial I/O, RAM,
ADC and PWM) and interrupt system to continue
functioning
• Power-down mode: saves the RAM contents but stops
the clock causing all other chip functions to be
inoperative.
8.2 CPU timing
A machine cycle consists of a sequence of 6 states. Each
state lasts one clock period, thus a machine cycle takes
6 clock periods or 1 µs if the clock frequency (fclk) is
6 MHz.
