ST72F651AR6T1集成电路（IC）的微控制器规格书PDF中文资料

ST72F651AR6T1属于集成电路（IC）的微控制器。由意法半导体集团制造生产的ST72F651AR6T1微控制器微控制器产品是相对复杂的用户可编程数字逻辑器件。这些产品与视为微控制器的器件密切相关，两者之间的区别主要体现在制造商选择的用词。不过按照传统，微控制器集成了工作存储器，也更可能包含混合信号外设，并且往往与更简单的软件范例结合使用，旨在重复执行一系列预定义的任务。

INTRODUCTION

The ST7265x MCU supports volume data exchange with a host (computer or kiosk) via a full speed USB interface. The MCU is capable of handling various transfer protocols, with a particular emphasis on mass storage applications.

■ Memories

– Up to 32K of ROM or High Density Flash (HDFlash) program memory with read/write protection

– For HDFlash devices, In-Application Programming (IAP) via USB and In-Circuit programming (ICP)

– Up to 5 Kbytes of RAM with up to 256 bytes stack

■ Clock, Reset and Supply Management

– PLL for generating 48 MHz USB clock using a 12 MHz crystal

– Low Voltage Reset (except on E suffix devices)

– Dual supply management: analog voltage detector on the USB power line to enable smart power switching from USB power to battery (on E suffix devices).

– Programmable Internal Voltage Regulator for Memory cards (2.8V to 3.5V) supplying: Flash Card I/O lines (voltage shifting) Up to 50 mA for Flash card supply

– Clock-out capability

■ 47 programmable I/O lines

– 15 high sink I/Os (8mA @0.6V / 20mA@1.3V)

– 5 true open drain outputs

– 24 lines programmable as interrupt inputs

■ USB (Universal Serial Bus) Interface

– with DMA for full speed bulk applications compliant with USB 12 Mbs specification (version 2.0 compliant)

– On-Chip 3.3V USB voltage regulator and transceivers with software power-down

– 5 USB endpoints: 1 control endpoint 2 IN endpoints supporting interrupt and bulk 2 OUT endpoints supporting interrupt and bulk

– Hardware conversion between USB bulk packets and 512-byte blocks
