Product speciﬁcation

Low voltage 8-bit microcontroller with

6-kbyte embedded RAM

SZF2002

FEATURES

• Fully static 80C51 Central Processing Unit (CPU)

• 8-bit CPU, ROM, RAM and I/O in a 80 lead LQFP

package

• 6-kbytes ROM program memory, expandable externally

to 256 kbytes

• 6144 + 256 bytes low power RAM data memory,

expandable externally to 32 kbytes

• Internal AUX RAM can be used for program execution

(only in combination with internal ROM)

• Three 8-bit ports; 24 I/O lines

• Three 16-bit timer/event counters

• Flash Memory Interface optimized, with power saving

and programming options

• Internal demultiplexing and latching of address/data bus

to reduce system component count

• Interfaces to up to 256-kbyte Flash Memory (banked)

• Fifteen source, fifteen vector nested interrupt structure

with two priority levels

• Full duplex serial port (UART)

• I2C-bus interface for serial transfer on two lines

• Analog-to-Digital Converter (ADC) with Power-down

mode; 6 input channels and 8-bit ADC

• Pulse Width Modulated (PWM) output (8-bit resolution)

• Watchdog Timer

• Enhanced architecture with:

– Non-page oriented instructions

– Direct addressing

– Four 8-byte RAM register banks

– Stack depth limited only by available internal RAM

(maximum 256 bytes)

– Multiply, divide, subtract and compare instructions

• Modes of reduced activity: Power-down and Idle modes

• Wake-up via external interrupts at INT0 to INT8

• Frequency range: up to 16 MHz (only limited by external

memory and ADC performance)

• Supply voltage: 3.0 V

• Very low power consumption:

operational 0.65 mW/MHz; Idle 0.25 mW/MHz at 3.0 V

• Operating temperature: −40 to +85 °C.

GENERAL DESCRIPTION

The SZF2002 low power system controller is

manufactured in an advanced 0.5

µm 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 I2C-bus refer to “The

I2C-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.
