ST ST72F651AR6T1

ST712 МГц32 КБ (32К x 8)

Overview

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 / [email protected])    – 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    (Continue ...)
