Integrerade kretsar


Integrerade kretsar ("IC-kretsar") är kretsar där en viss logisk eller analog funktion realiserats genom att kombinera ett antal transistorer på samma kiselbricka. Detta gör att samma funktion kan realiseras på mindre yta än om den realiserats med diskreta transistorer.

Det finns huvudsakligen två typer av kapsling för integrerade kretsar; hålmonterade (DIP-) och ytmonterade (SO-). De flesta kretsar finns i både hålmonterat och ytmonterat utförande.

  MC68SEC000AA20 QFP-64 MPU 32-bit 20MHz
The MC68SEC000 is a cost-effective static embedded processor engineered for low-power applications. In addition to providing the substantial cost and performance benefits of the MC68EC000, the low-power mode of the MC68SEC000 provides significant advantages in power consumption and power management. The typical current consumption of the MC68SEC000 is only 0.5µA in static standby mode and 15.0mA in normal 3.3V operation. The MC68SEC000 operates in either 3.3V or 5.0V systems. The remarkably low power consumption, small footprint packages, and static implementation are combined in the MC68SEC000 for low-power applications such as personal digital assistants, portable measuring equipment, electronic games, and batteryoperated hand-held consumer products. The HCMOS MC68SEC000 static architecture is a direct replacement for the MC68EC000, which offers the lowest cost entry point to 32-bit processing. The internal 32-bit architecture provides fast and efficient processing that satisfies the requirements of sophisticated applications based on high-level languages. In addition to being pin-for-pin compatible with the MC68EC000, the MC68SEC000 is object-code compatible with any member of the M68000 Family. Complete code compatibility lets system designers reduce time to market because they can rely on existing M68000 Family code and a broad base of established development tools. The primary features of the MC68SEC000 embedded processor include the following: Direct Replacement for the MC68EC000 Pin-for-pin compatibility with the MC68EC000 in the plastic QFP package Vast selection of existing third-party development tools for the MC68EC000 support the MC68SEC000 Software written for the MC68EC000 will run unchanged on the MC68SEC000 Power Management Low power HCMOS technology Static design allows for stopping the processor clock 3.3V or 5V operation Typical 0.5µA current consumption at 3.3V in sleep mode Architecture Eight 32-bit address registers Eight 32-bit data registers 16-Mbyte linear addressing range 56 powerful instruction types Operations on five main data types Memory-mapped I/O 14 addressing modes Software Strength Fully upward object-code compatible with other M68000 Family products M68000 architecture allows effective assembly code with a C compiler Available Packages 64-pin plastic Quad Flat Pack (QFP) 64-pin Thin Quad Flat Pack (TQFP) Speed 10/16/20 MHz Upgrade Fully upward code-compatible with higher performance 680x0 and 68300 Family members ColdFireTM code-compatible with minor modifications
