Manufacturer:ZILOG Description:The ST92F120 microcontroller is developed and manufactured by STMicroelectronics using a pro- prietary n-well HCMOS process. Its performance derives from the use of a flexible 256-register pro- gramming model for ultra-fast context switching and real-time event response. The intelligent on- chip peripherals offload the ST9 core from I/O and data management processing tasks allowing criti- cal application tasks to get the maximum use of core resources. The new-generation ST9 MCU devices now also support low power consumption and low voltage operation for power-efficient and low-cost embedded systems. 1.1.1 ST9+ Core The advanced Core consists of the Central Processing Unit (CPU), the Register File, the Inter- rupt and DMA controller, and the Memory Man- agement Unit. The MMU allows a single linear ad- dress space of up to 4 Mbytes. Four independent buses are controlled by the Core: a 16-bit memory bus, an 8-bit register data bus, an 8-bit register address bus and a 6-bit inter- rupt/DMA bus which connects the interrupt and DMA controllers in the on-chip peripherals with the core. This multiple bus architecture makes the ST9 fam- ily devices highly efficient for accessing on and off- chip memory and fast exchange of data with the on-chip peripherals. The general-purpose registers can be used as ac- cumulators, index registers, or address pointers. Adjacent register pairs make up 16-bit registers for addressing or 16-bit processing. Although the ST9 has an 8-bit ALU, the chip handles 16-bit opera- tions, including arithmetic, loads/stores, and mem- ory/register and memory/memory exchanges. The powerful I/O capabilities demanded by micro- controller applications are fulfilled by the ST92F120 with 77 I/O lines dedicated to digital In- put/Output. These lines are grouped into up to ten 8-bit I/O Ports and can be configured on a bit basis under software control to provide timing, status signals, an address/data bus for interfacing to the external memory, timer inputs and outputs, analog inputs, external interrupts and serial or parallel I/O. Two memory spaces are available to support this wide range of configurations: a combined Pro- gram/Data Memory Space and the internal Regis- |
