ST72521R Détails du produit

INTRODUCTION

The ST72F521 and ST72521B devices are members of the ST7 microcontroller family designed for mid-range applications with a CAN bus interface(Controller Area Network).

All devices are based on a common industry standard 8-bit core, featuring an enhanced instruc tion set and are available with FLASH or ROM program memory.



■ Memories

   – 32K to 60K dual voltage High Density Flash (HDFlash) or ROM with read-out protection capability. In-Application Programming and In-Circuit Programming for HDFlash devices

   – 1K to 2K RAM

   – HDFlash endurance: 100 cycles, data retention: 20 years at 55°C

■ Clock, Reset And Supply Management

   – Enhanced low voltage supervisor (LVD) for main supply and auxiliary voltage detector (AVD) with interrupt capability – Clock sources: crystal/ceramic resonator os cillators, internal RC oscillator and bypass for external clock

   – PLL for 2x frequency multiplication

   – Four power saving modes: Halt, Active-Halt, Wait and Slow

■ Interrupt Management

   – Nested interrupt controller

   – 14 interrupt vectors plus TRAP and RESET

   – Top Level Interrupt (TLI) pin

   – 15 external interrupt lines (on 4 vectors)

■ Up to 64 I/O Ports

   – 48 multifunctional bidirectional I/O lines

   – 34 alternate function lines

   – 16 high sink outputs

■ 5 Timers

   – Main Clock Controller with: Real time base, Beep and Clock-out capabilities

   – Configurable watchdog timer

   – Two 16-bit timers with: 2 input captures, 2 output compares, external clock input on one timer, PWM and pulse generator modes – 8-bit PWM Auto-Reload timer with: 2 input captures, 4 PWM outputs, output compare and time base interrupt, external clock with event detector

■ 4 Communications Interfaces

   – SPI synchronous serial interface

   – SCI asynchronous serial interface

   – I2C multimaster interface (SMbus V1.1 compliant)

   – CAN interface (2.0B Passive)

■ Analog periperal (low current coupling)

   – 10-bit ADC with 16 input robust input ports

■ Instruction Set

   – 8-bit Data Manipulation

   – 63 Basic Instructions

   – 17 main Addressing Modes

   – 8 x 8 Unsigned Multiply Instruction

■ Development Tools

   – Full hardware/software development package

   – In-Circuit Testing capability
