Description



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.


Application

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.

Description

The SZF2002 low power system controller is manufactured in an advanced 0.5 mm 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.
