GENERAL DESCRIPTION

1.1 INTRODUCTION Due to the fully static design of this device, operation down to DC is possible. Under software control the ST7275 can be placed in WAIT or HALT mode thus reducing power consumption. The enhanced instruction set and addressing modes afford real programming potential. Figure 1. ST7275-2 Block Diagram In addition to standard 8-bit data management the ST7 features true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes. The device includes an on-chip oscillator, CPU, Sync Processor for video timing & Vfback analysis, up to 32K ROM, up to 1K RAM, I/O, a timer wi...
