ST7263B
1 INTRODUCTION
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 fre-
quency. 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 in-
clude an ST7 Core, up to 16 Kbytes of program
memory, up to 512 bytes of RAM, 19 I/O lines and
the following on-chip peripherals:
– USB low speed interface with 3 endpoints with
– 8-bit Analog-to-Digital converter (ADC) with 8

The ST7263B devices are ROM versions.
The ST72P63B devices are Factory Advanced
Service Technique ROM (FASTROM) versions:
they are factory-programmed and are not repro-
grammable.
The ST72F63B devices are Flash versions. They
support programming in IAP mode (In-application
programming) via the on-chip USB interface.
