ST72F63BK4M1

低速USB 8位MCU系列具有高达32 KB的闪存/ ROM ， DFU功能， 8位ADC ， WDG ，定时器， SCI和I²C Low speed USB 8-bit MCU family with up to 32 KB Flash/ROM, DFU capability, 8-bit ADC, WDG, timer, SCI and I²C

The ST7263B microcontrollers form a sub-family of the ST7 MCUs dedicated to USB applications. The devices are based on an industry-standard 8-bit core and feature an enhanced instruction set. They operate at a 24 MHz or 12 MHz oscillator frequency. Under software control, the ST7263B MCUs may be placed in either Wait or Halt modes, thus reducing power consumption. The enhanced instruction set and addressing modes afford real programming potential. In addition to standard 8-bit data management, the ST7263B MCUs feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes. The devices include an ST7 Core, up to 32Kbytes of program memory, up to 1024 bytes of RAM, 27 I/O lines and the following on-chip peripherals: USB low speed interface with 3 endpoints with programmable in/out configuration using the DMA architecture with embedded 3.3V voltage regulator and transceivers no external components are needed.8-bit analog-to-digital converter ADC with 12 multiplexed analog inputs Industry standard asynchronous SCI serial interfaceWatchdog 16-bit timer featuring an external clock input, 2 Input Captures, 2 Output Compares with Pulse Generator capabilitiesFast I2C multimaster interfaceLow voltage reset LVD ensuring proper power-on or power-off of the device

The ST72F63B devices are Flash versions. They support programming in IAP mode in-application programming via the on-chip USB interface.
