The ST7260 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 ST7260 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 ST7260 MCUs feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes. The devices include an ST7 Core, up to 8Kbytes of program memory, up to 384 bytes of RAM, 19 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).
– Industry standard asynchronous SCI serial interface
– Watchdog
– 16-bit Timer featuring an External clock input, 2 Input Captures, 2 Output Compares with Pulse Generator capabilities
– Low voltage reset (LVD) ensuring proper poweron or power-off of the device
The ST72F60 devices are Flash versions. They support programming in IAP mode (In-application programming) via the on-chip USB interface.
