GENERAL DESCRIPTION
The SZF2002 low power system controller is
manufactured in an advanced 0.5
μ
m CMOS technology.
The instruction set of the SZF2002 is based on that of the
80C51 and consists of over 100 instructions: 49 one-byte,
46 two-byte, and 16 three-byte. The device has low power
consumption and two software selectable modes for
power reduction: Idle and Power-down.
This data sheet details the specific properties of the
SZF2002; for details of the 80C51 core and peripheral
functions such as timers, UART and I/O, see
“Data Handbook IC20” For the I

C-bus and how to use it” ordering number
9398 393 40011.

APPLICATIONS
The SZF2002 is an 8-bit general purpose microcontroller
especially suited for wireless telephone and battery
powered applications. The SZF2002 also functions as an
arithmetic processor having facilities for both binary and
BCD arithmetic plus bit-handling capabilities.
