The devices are based on an industry-standard 8-bit core and feature an enhanced instruction set. They operate at an 24MHz oscillator frequency. Under software control, the ST7263 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 ST7263 MCUs feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes. The devices include an ST7 Core, up to 16K program memory, up to 512 bytes RAM, 19 I/O lines and the following on-chip peripherals: - USB low speed interface with 3 end points 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 8 multiplexed analog inputs Table 1.

The ST72T63x are the One Time Programmable (OTP) versions in SO34/PSDIP32 packages. The ST7263x are the ROM versions in SO34/ PSDIP32 packages. A specific mode is available to allow programming of the EPROM user memory array. This is set by a specific voltage source applied to the VPP/TEST pin.
