ST72321R6规格书详情
INTRODUCTION
The ST72321R, ST72321AR and ST72321J devices are members of the ST7 microcontroller family designed for mid-range applications All devices are based on a common industry standard 8-bit core, featuring an enhanced instruction set and are available with FLASH or ROM program memory.
Under software control, all devices can be placed in WAIT, SLOW, ACTIVE-HALT or HALT mode, reducing power consumption when the application is in idle or stand-by state.
■ 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, clock security system 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 on 64-pin devices
– 15 external interrupt lines (on 4 vectors)
■ Up to 48 I/O Ports
– 48/32 multifunctional bidirectional I/O lines
– 34/22 alternate function lines
– 16/12 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
■ 3 Communications Interfaces
– SPI synchronous serial interface
– SCI asynchronous serial interface (LIN compatible)
– I2C multimaster interface
■ 1 Analog peripheral
– 10-bit ADC with up to 16 input pins
■ 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
