1 Introduction
www.DInattaroShdeuect4tiUo.cnom
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 32 Kbytes 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 3.3 V 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 interface
● Watchdog
● 16-bit Timer featuring an External clock input, 2 input Captures, 2 output Compares
with Pulse Generator capabilities
● Fast I²C multimaster interface
● Low 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.
